New approaches in nature conservation
‘This grant is indicative of high appreciation for the work we’ve already done and represents active support of our plans for the future’, said Tatiana Minayeva, project coordinator at Wetlands International.

Minayeva: ‘We are glad that the bank helps meet the challenge of restoring peatland ecosystems, which is very important for the ecological situation in Russia, and contributes to the implementation of the most up-to-date technologies and approaches to nature conservation’.

IIB’s chairman of the board, Nikolay Kosov, mentioned that the restoration projects fully complies with the mission of his institution as a diversified development bank.

‘All-around support of green projects and consistent environmental protection activities are the bank’s strategic priority to which we will continue to adhere”, Kosov said.

dws-wetlands-russia-gis-map-350px GIS based decision making instrument on peatlands management has already been developed for local authorities.

Rewetting degraded peatlands
Millions of hectares of drained and abandoned peatlands in European Russia are highly vulnerable to fires, such as those that covered Moscow in smoke during the extremely dry summer of 2010.

Rewetting degraded peatlands, especially abandoned peat mining sites, and establishing a sustainable usage will prevent fires and their negative impacts on climate and biodiversity.

The project aims to restore the hydrological regime in an area of around 15,000 ha in the Moscow, Vladimir and Tver provinces, including 11,000 ha.

GIS-based decision making
The partners use state-of-the-art technologies for nature conservation, including the mapping of peatland with remote sensing, prioritisation of sites based on a decision support system and a GIS based peatlands management system.

A specially developed peatland management system has already been handed over to the Government of the Moscow Province.

The total amount of emission reductions already achieved is estimated at 175,000 to 220,000 tons CO2 equivalent per annum.

Acacia Water is conducting a robust hydrologic study in Darfur, Western Sudan, and the outcome will be used for a water buffering masterplan.

This plan will show the opportunities for sustainable water resources development of the individual hydrologic catchments (watersheds) where the involved communities are located.

Acacia Water will develop the plan as part of the Taadoud project, a new project for Catholic Relief Services in Sudan funded by UK’s Department for International Development (DFID).

dws-acacia-dafur3-goats-350px Drought in Dafur makes cattle herders to travel to areas with more water. Their cattle damages the crops of local farmers and this leads to conflicts between pastures (livestock) and farmers (agriculture).

Conflict and displacements
In Sudan, protracted conflict and displacement of communities are coupled with economic and political uncertainty, climatic variability, and environment degradation.

The Taadoud project aims at simultaneously improving the productivity of livelihoods and strengthening community-level disaster risk reduction and climate change adaptation in Darfur.

To do so, the project uses a holistic approach of natural resource management, necessary in such complex and fragile context.

Water balance calculations
Acacia Water is currently conducting a hydrologic study of the project area including map development, water balance calculations and an assessment of the current water infrastructure.

Based on this water resources assessment, a Water Buffering Master Plan will be developed for the project areas.

SNV receives 39.5 million grant for smart agriculture projects in Kenya, Tanzania and Uganda https://www.dutchwatersector.com/news-events/news/31838-snv-receives-39-5-million-grant-for-smart-agriculture-projects-in-kenya-tanzania-and-uganda.html dws-snv-smart-agri-irrigation-770px
The Netherlands Ministry of Foreign Affairs has granted funding of 39.5 million euro to implement a 5-year Climate Smart Agriculture programme in Kenya, Tanzania and Uganda to a consortium led by development organisation SNV Netherlands.

The programme aims to increase food production and food security in these three African countries by enhancing climate resilience throughout the supply chain. One of the issues is adapting the way communities farm to more frequent drought.

Other participants in the consortium are Wageningen University and Research, CGIAR’s Climate Change Agriculture and Food Security Programme, Agriterra, and Rabo Partnerships.

dws-snv-smart-farming-crop-350px More crop will raise the income of farmers.

By 2022 this will result in adaptive productive capacity and increased incomes for 300,000 medium sized and smallholder producers. On top of that we will improve business performance of 50 small medium enterprises and 30 cooperatives to mitigate the risks of climate change on their supply chains.

‘This grant will help us scale up our support to farmer communities to feed their families and increase their income. This will require adapting the way they farm to more frequent drought and other climate-related changes’, said Meike van Ginneken, CEO of SNV.

dws-snv-smart-farming-drip-irrigation-kenya-350px Drip irrigation is an option to preserve water and grow crops in a dry period.

Scaling to systemic change
The programme uses a three pronged approach. It will implement complementary interventions to increase adoption of climate smart practices and technologies among farmers and SMEs.

Furthermore, it will stimulate their growth throughout the value chain by enhancing private sector investments in climate adaptation.

And finally, it will advocate with partners and the government of the three targeted countries to encourage a favourable enabling environment for large scale market adoption.

Financial sector partners
To achieve this the consortium will collaborate with private and financial sector partners such as Rabobank - who will pave the way for financially viable Climate Smart Agriculture solutions and investment to agribusinesses.

Dutch expertise in sustainable food production systems, particularly in potatoes, oilseeds and pulses will be mobilised.

The programme activities will be in line with existing government strategies like the National Climate Plans and collaborate with multilateral climate investments and the Embassy of the Netherlands in all three countries.

Single-lift vessel Pioneering Spirit installs 22,000 ton drilling platform in North Sea https://www.dutchwatersector.com/news-events/news/31820-single-lift-vessel-pioneering-spirit-installs-22-000-ton-drilling-platform-in-north-sea.html dws-alleseas-sverdrup-nearing-770px
Allseas’ single-lift vessel Pioneering Spirit marked a milestone on 2 June with the safe and successful installation of the 22,000 ton drilling platform topsides in the Johan Sverdrup field on the Norwegian continental shelf.

It was the first platform installation job performed by Pioneering Spirit, and the heaviest installation ever executed in a single lift offshore to date.

The 382 m long Pioneering Spirit is the largest construction vessel in the world, designed for the single-lift installation and removal of large oil and gas platforms and the installation of heavy underwater pipelines. The maximum capacity to lift a platform topside is 48,000 ton.

dws-allseas-sverdrup-lifting-from-barge-350px The Pioneering Spirit lifts the topsides from the barge in Bømlafjorden.

Precise manoeuvring
The operation started with the transfer of the 147 m tall topsides (right on top photo) to Pioneering Spirit (left) by barge in Bømlafjorden, just north of Stavanger, Norway.

Nine hours later the vessel arrived with her cargo in the Johan Sverdrup field and immediately started using its dynamic position system to manoeuvre around the eight-legged steel jacket that had been fixed to the 110 m deep sea floor.

The precise manoeuvring, setting down the topsides on the jacket and moving out of the 500 m zone, only took three hours.

dws-allseas-sverdrup-placed-in-fog-350px Despite the fog on the North Sea, the topside deck was put on the jacket (in yellow) in only three hours.

Single lift
Up until now big topsides have been modular in design and put in place by crane vessels. However, crane vessels have not been able to lift more than 12,000 tonnes in one lift.

The brand new lifting technology on Allseas‘ Pioneering Spirit vessel allows entire topsides of up to 48,000 tonnes to be lifted in one, single lift.

Initially the vessel was developed for the removal of scrapped platforms. Equinor is the first user of the technology for the installation of big, new topsides.

This allows for great savings in the construction and installation phases, both in terms of manhours and costs.

Two more topsides
The drilling platform topsides are the first of three structures Pioneering Spirit will install during the Johan Sverdrup field’s first development phase.

The heavy lift vessel will return to the field in the spring of 2019 to install the 26,000 ton process platform topside and the 18,000 ton living quarters platform topside.

Delft researchers to study floating tunnel between Hainan island and Chinese mainland https://www.dutchwatersector.com/news-events/news/31803-delft-researchers-to-study-floating-tunnel-between-hainan-island-and-chinese-mainland.html dws-tudel-ft-floating-tunnel-hainan-750pxChinese engineering and construction company CCCC has plans to develop a submerged floating tunnel to cross the 120 m deep Qiongzhou Strait.

Researchers of the Delft University of Technology have been asked to be part of the project.

A submerged floating tunnel has never been built before and Delft research will look into the risks of such an option to connect the Hainan island to the China mainland.

dws-tu-delft-floating-tunnel-hainan-scheme-350px   CCCC has four options to choose from..

Technically difficult to build
Submerged floating tubes allow the construction of tunnels in extremely deep water where conventional bridges or tunnels are technically difficult to build or prohibitively expensive.

Depending on the buoyancy of the tunnels, cables anchored to the sea bed or to pontoons at the surface would prevent them from floating to the surface or submerging, respectively.

More Dutch engineers involved
‘We are getting this project started,’ says professor Bas Jonkman, Head of the Hydraulic Structures and Flood Risk section of TU Delft Faculty of Civil Engineering and Geosciences, adding that more Dutch engineers such as engineers from the company TEC (Tunnel Engineering Consultants) are also involved.

‘We just signed the contracts and we are waiting for the Chinese to do the same. We will be hiring two PhD students, part of whose task is to look into the risk analyses. In the meantime, we already have bachelor students performing experiments with possible prototypes in our labs in Delft.’

dws-tudel-ft-floating-tunnel-hainan-map-350px The Qiongzhou Strait is 30 km wide and 120 m deep and is prone to earthquakes and typhoons.

‘The idea is to place the tube underwater, deep enough to avoid water traffic and weather, but not that deep that we need to deal with high water pressure,’ says Jonkman. ‘As a general rule of thumb, you can say that there is potential for floating tubes instead of tunnels on the sea floor for depths of 50 metres or more.’

But this is just theory. Though many countries have shown interest, namely Norway with its very deep fjords, a submerged floating tunnel has never been built before.

Airport at sea
Jonkman recently proposed a submerged floating tunnel to link the Netherlands with a yet to be built airport at sea, especially if the airport island is to be constructed in the deeper parts of the North Sea.

The Dutch Parliament has requested a study into the feasibility of a new airport on an artificial island in the North Sea.

Ocean Cleanup successfully completes first tow test in Pacific Ocean https://www.dutchwatersector.com/news-events/news/31777-ocean-cleanup-successfully-completes-first-tow-test-in-pacific-ocean.html dws-ocean-cleanup-tow-test-sets-out-770px
The Ocean Cleanup has successfully completed a two week tow test with a 120-meter floater segment of its ocean garbage collection system.

The test started with the assembly of the segment on Alameda Point, a former naval base, in California. Once completed the unit was towed to the Pacific Ocean, some 50 miles outside of San Francisco’s Golden Gate.

The segment was towed in various directions to test its hydrodynamics behaviours. The next step is to tow a 600 m long segment and test it in a fully operational configuration.

dws-ocean-cleanup-tow-test-screen-350px  Assembly of the floater segment with the screen underneath.

With and against the current
The purpose of the tow test is to see how the system behaves in the water, as well as the screen’s performance under tow and during various manoeuvres at sea.

To confirm the system’s behaviour at sea, the tug (on top photo when leaving Alameda Point) followed an elaborate pattern, going with and against the current and the waves, and under different weather and sea conditions.

The test segment departed from San Francisco Bay with the screen pulled up to the floater.

Screen down
The screen was lowered only after the first testing pattern had been completed, after which the entire pattern was repeated once more, with the screen down.

Engineers monitored and recorded the system responses in order to find the safest and most efficient way to transport it the much greater distance of more than 1,000 nautical miles it will go to get to the Pacific Ocean patch.

dws-ocean-clenaup-san-francisco-sensors-350px Checking the system’s electronic components. The system relies on the sun to power everything from AIS, satellite communications, cameras and sensors.

Drifting behaviours
The screen is the part of the system that is meant to concentrate the sub-surface plastics against the floaters.

It also plays an important role in the drifting behaviour of the system once it is fully deployed to freely move on the currents and the wind.

The 120 m segment will now be used for the next tow test with a 600 m segment that will also include the custom-built tow heads.

The full collection System 001 will be taken to international waters, 220-240 nautical miles off-shore from San Francisco.

After gathering all practical knowledge needed to tow the full-length system safely, it will be transported into the patch later this summer to begin cleaning.

Justdiggit handed out 240 used smart phones to the facilitators of their regreening project in the Kongwa district, Tanzania. The smart phones enable the facilitators not only to communicate better but also to monitor the progress of the project by taking pictures of trees.

The phones have been installed with a special app to collect the monitoring data.

dws-justdiggit-kisiki-hai-tree2-350px Tree restoration and rainwater catchment are two important elements of  the Farmer Managed Natural Regeneration method.

Restoring degraded landscapes
Together with the LEAD Foundation, Justdiggit conducts a 180.000 hectare regreening project in Tanzania involving some 300 communities to restore trees, improve soil conditions and re-introducing rainwater harvesting practices.

To re-green the landscape and improve the productivity of the land, the project uses the specially developed Farmer Managed Natural Regeneration (FMNR) method, called Kisiki Hal in Swahili.

Real time progress
Njamasi Chiwanga, partner LEAD Foundation: ‘The smartphones, while simplifying communication among our team of hundreds of community facilitators, will also be used in our monitoring and evaluation track whereby we’ll be able to monitor real time progress and photos of trees in the villages using the Kobotool app.’

The smart phones originally come from the Dutch Railway Company NS and are now given a second life in Tanzania.

dws-justdiggit-kisiki-hai-hill-350px Once vegetation regrows, erosion stops and a local water cycle of rain fall and evaporation will return. 

About Justdiggit
Dutch-based foundation Justdiggit runs several large regreening projects in Africa based on their system approach, called the Hydrologic Corridor.

By restoring degraded landscapes, using rainwater harvesting, soil improvements and re-greening techniques, the vegetation will regrow. As a consequence the water cycle will be restored. This is the key to sustainable re-greening and contributing to regional cooling and more equally distributed rain.

By conducting several large scale projects in Africa the foundation aims to able to change the regional climate by capturing CO2, reducing local temperature and creating local rains.

US-Dutch collaboration on new adsorbents for removal of micropollutants https://www.dutchwatersector.com/news-events/news/31740-us-dutch-collaboration-on-new-adsorbents-for-removal-of-micropollutants.html dws-wibo-cyclopure-wwtp-horstermeer-740px
Dutch-based organisations Water utility Waternet and engineering firm Witteveen+Bos announced their collaboration with CycloPure (USA) that is commercializing a new class of selective adsorbents to deal with micropollutants of emerging concern such as pharmaceuticals, pesticides and per- and polyfluoroalkyl substances (PFAS).

Based on extensive research at Cornell University and Northwestern University (USA), CycloPure designed an adsorbent called High Affinity Cyclodextrin Polymers (HACPs) that is now in early production and pilot testing.

Witteveen+Bos and Waternet jointly evaluate the potential of these promising adsorbents for effluent polishing at waste water treatment plants in the Netherlands, and develop the best suitable treatment concept.

dws-wibo-cyclopure-graphic-bpa-removal-350px CycloPure claims the uptake of Bisphenol-A (BPA) by its CD-MP in seconds as compared to minutes for activated carbon.

Rapid uptake
CycloPure’s technology allows the conversion of renewable cyclodextrins - derived from corn starch - into highly adsorbent materials that are ideally suited for water treatment applications.

Its adsorbents gain their strong binding affinity from cyclodextrin inclusion complexes that are optimally sized for the attraction and removal of micropollutants.

With high capacity and rapid uptake at trace pollutant concentrations, CycloPure’s HACPs feature lower dosing to achieve adsorption objectives, and can be regenerated on-site with a very high reuse percentage.

About partners
Witteveen+Bos provides consulting- and engineering services for several regional Dutch water authorities and is highly involved in the micropollutant topic.

Waternet is the water utility for Amsterdam that built a full-scale effluent polishing plant (in front on top photo) removing micropollutants in 2012 and are currently optimizing this system.

CycloPure has developed two novel adsorbent formulations, CD-MP and CD-PFAS, for the removal of micropollutants from water. The company’s patented HACPs can be produced in varying particle sizes, allowing for flexible use across a broad spectrum of water treatment applications.

VP Delta opens living lab facility for new storm water catchment concepts https://www.dutchwatersector.com/news-events/news/31706-vp-delta-opens-living-lab-facility-for-new-storm-water-catchment-concepts.html  dws-vpdelta-water-street-kreijns-kuijken-770px-1
Valorisation Programme Delta Technology & Water, VP Delta, officially opened its demonstration facility for new concepts for a more smart way to handle storm water in cities.

As a result of the expected increase of extreme rainfall events, several Dutch SME-companies developed innovative concepts to handle extreme volumes of storm water and store in underneath hardened urban surface.

The testing ground was officially opened by Delta Programme Commissioner Wim Kuijken and Water Board Council Chair Michiel van Haersma Buma on 16 May.

Local retention, anticipating on dry periods
VP Delta took the initative to gather 12 new concepts at one location on the campus of the Delft University. The facility got the appropriate name of Water Street.

A smart aspect of the new concepts is the local retention of the storm water runoff to anticipate on dry periods. 

‘The Netherlands is more often faced with extreme showers’, said Marjan Kreijns (right on top photo), program director of VPdelta during the opening ceremony. ‘We cannot change the weather, but we can try to limit the nuisance and damage.’

Special Deltacommissioner Wim Kuijken (second right on top photo) called the testing ground a wonderful opportunity to take the next steps towards a nationwide climate proof and water resilient approach. Kuijken: ‘Use this testing ground to study and innovate together, and to bring about a transition. A transition to a new way of spatial planning. A way in which climate-proof action becomes standard practice.’

Further development of concepts
The facility is the intermediate step between a laboratory setup and actual application in the public space.

It features several abilities for the SME’s to further develop their concept. For instance, there is a special shower that can be used to simulate extreme rainfall.

It is also possible for the SME’s to use researchers of the Civil engineering department of the Delft university.

At the same time the Water Street offers the possibility to demonstrate the concept to municipalities, water authorities, estate owners, or even foreign water delegations visiting The Netherlands.

dws-vpdelta-water-street-smart-barrel-350px The Smart water barrel that can be programmed to slowly release its water before an extreme rain shower hits.

Three storm water concepts
The Water Street shows 12 different solutions to handle storm water in cities. These include:
● Urban Rainshell by Ecological Water Management
An underground storm water buffering and purification system with shells and minerals to purify the collected road run off water. The treated run off water allows local re use for instance as fire water, irrigation of sport fields and process water.
● Flowsand by Aquaflow
a special kind of sand for use in street pavements so the rain water drains more rapidly and prevents clogging. The sand has a capillary effect on the rain water so the street will be water free more quickly.
● Smart rain barrel by Studio Bas Sala
a rain barrel with a tap that can also be operated online and linked to the local weather forecast. In case a heavy rain shower is predicted, the barrel can slowly be emptied in advance, so the full retention capacity can be used during the actual rain fall.

The Water Street is an initiative of The Green Village, the regional Delfland Water Authority and VP delta.

Three Dutch NGOs sign mondial agreement to scale up sanitation projects https://www.dutchwatersector.com/news-events/news/31666-three-dutch-ngos-sign-mondial-agreement-to-scale-up-sanitation-projects.html dws-a4a-finish-tripartite-mou-signing-770px
During the Dutch trade mission to India, headed by Dutch Prime Minister Mark Rutte, a Finish mondial partnership agreement was signed between the non-governmental organisations Waste, Amref Health Africa and Aqua for All.

The partnership aims to scale up safe sanitation for the poor through Public Private Partnerships (PPPs), thereby contributing to Sustainable Development Goal 6 on water.

dws-a4a-finish-toilet-donald-duck-350px  With small grants as seed money, the Finish society wants to build millions of new toilets in India. The concept will now be scaled up to six countries.

Leveraging local finance
Finish - financial inclusion improves sanitation and health - is a programme initiated by Dutch-based non-profit organisation Waste, with ongoing success in India and Kenya that started in 2009 and 2013 respectively.

The agreement includes a sanitation impact bond. This starts as a pilot with 5 million euro from Dutch institutional investors expected to be scaled up to a 100 million euro bond, if successful.

Head of the Dutch mission, Prime Minister Mark Rutte, emphasized: ‘The basis for success is cooperation between government, private sector and communities to address challenges in the local context. For a comprehensive solution, we need collective action’.

700,000 toilets already realised
The Finish programme has already been able to leverage significant local financing for safe sanitation. In India, less than 5 per cent of the initial FINISH funding came from grants.

As a result, by 2017 3.1 million people enjoyed the benefits of safe sanitation thanks to nearly 700,000 toilets and the creation of over 5,000 jobs.

To scale up results, WASTE, Amref Health Africa and Aqua for All, under the new FINISH Mondial partnership agreement – will expand FINISH in 6 priority countries, including India, Kenya, Uganda, Ethiopia, Tanzania and Bangladesh.

dws-a4a-finish-toilet-masonkhund-350px The Finish society involves constructors and faecal sludge remover, so many new jobs are created as well.

First sanitation impact bond
During the Dutch trade mission to India, a first of its kind Sanitation Impact Bond was launched.

Agreements were signed with partners including Actiam, KPMG, Waste, ESAF and Cashpor Micro Credit. Starting with a pilot phase of 5 million euro, the Bond aims to raise 100 million euro from institutional investors to build 1.5 million toilets in three years.

The funds will be invested in Indian microfinance institutions who will extend loans for sanitation and repay the Dutch Institutional Investors through Dutch Impact investor Actiam with a small return.

One of the truly innovative factors is that if the impact is reached in the number of sanitation systems constructed (target 1.5 million toilets), the Indian microfinance institutions will be rewarded in the form of lower interest rates.

Simulations show four folding of damage at most densely-populated Pacific island in near future https://www.dutchwatersector.com/news-events/news/31644-simulations-show-four-folding-of-damage-at-most-densely-populated-pacific-island-in-near-future.html dws-deltares-ebeye-island-aerial2-770px
Simulations by scientists from Dutch research centre Deltares and Joint European Research Centre show that the Marshall island Ebeye is becoming more vulnerable to natural disasters and sea level rise.

The annual damage is already very extensive in the present situation. According to the scientists this may constitute a serious threat to the daily life of local inhabitants and the economies of the Marshall Islands and other low-lying island countries. Ebeye is with 4,000 inhabitants the most densely populated Marshall Island in the Pacific. The scientists published their findings in the most recent issue of Journal of Regional Environmental Change.

dws-deltares-ebeye-risk-scheme2-350px Damage at Ebeye is expected to four fold by 2100. Predicted development of annual damage (in US dollar/m2) on Ebeye (Giardino et al., 2018)

Factor four more damage
The island of Ebeye is a small strip of land on the Kwajalein atoll (Republic of the Marshall Islands) in the middle of the Pacific Ocean. It has an average height of about 2 m above mean sea level and so it is highly vulnerable to natural hazards and climate change.

‘Annual damage to property and infrastructure may increase on Ebeye by a factor of three to four by the end of the century according to standard RCP scenarios for sea level rise,’ says Alessio Giardino, one of the researchers and a coastal engineer and disaster risk specialist at Deltares.

State-of-the-art modelling
Simulations were carried out at Deltares using a state-of-the-art modelling train that included the assessment of offshore hazards, an assessment of the impact on property and the population on the islands, and the presentation of the results as risk maps and cost-benefit analyses, all for a range of climate change scenarios.

Useful input for a resilience project
‘Quantitative risk-based information is extremely useful to help increase resilience and improve planning for small islands’, says Denis Jean-Jacques Jordy, lead environmental specialist at the World Bank.

dws-deltares-ebeye-flooded-streets-350px Flooding on the island of Ebeye during a daily, non-extreme, event

‘This study informed the preparation of a 49 million US dollar resilience project funded by the World Bank and the Green Climate Fund.’ According to Jordy the results can also serve as a proxy for many other islands in similar situations.

The study was conducted in close collaboration between Dutch scientists from Deltares, the SISRI team from the Global Facility of Disaster Reduction and Recovery of the World Bank, the Joint Research Centre from the European Commission and the government of the Republic of Marshall Islands. The study was published in the Journal of Regional Environmental Change.

IFAT 2018: A look back on a successful and diverse Dutch participation https://www.dutchwatersector.com/news-events/news/31599-ifat-2018-a-look-back-on-a-successful-and-diverse-dutch-participation.html dws-ifat2018-photo-00-pavilion-770px
The organisers of the environmental trade fair IFAT 2018 expected over 130,000 visitors. As it turned out, the number was over 141,000. A rise of 4 percent, underlining the claim by the organisers that the demand for environmental technology products, including water treatment, is rising all over the world.

The 2018 edition of IFAT took place from 14 to 18 May and hosted a record number of over 75 participants from the Dutch water sector.

Numerous delegations
‘IFAT presents the technologies of the future for clean environment, hence, it is driving the public discourse more actively than ever before’, said Stefan Rummel, Managing Director of Messe München in response to the new visitor’s record.

‘This was reflected in the visits of international politicians’, Rummel continued, ‘the numerous delegations from all over the world and technology experts who came to share ideas, experiences and knowhow’.

A look back
The Dutch water sector offered a very wide range of sustainable solutions on efficient (waste) water management, purification, nutrient recovery, water reuse, smart monitoring, and other appropriate water technologies.

An overview of the exhibitors at the well-visited Netherlands Pavilion can be found on a special section of this website.

Below a selection of photos that illustrate some of the Dutch exhibitions and presentations.

Most sustainable evaporator in the world
Water technology supplier Cirtec officially launched its latest version of the GaLiCos evaporator at IFAT. Carlijn LaHaye (left) and Harry Tuinier revealed the first example of the fully synthetic Crescendo-version. According to CirTec it brings the most sustainable evaporator to date to the market. By using high-quality recyclable plastic, the new design can be applied to thicken liquids in an exceptional wide PH-range from 1 to 14 at temperatures ranging from 30 to 100°C.

Strategies on removal of micropollutants
At a special forum, representatives of the European Commission, and German, Dutch and French environmental ministries, explained their national strategies to combat micropollutants in surface water. Apparently, all are currently talking to a wide range of stakeholders, from the chemical and pharmaceutical industries to the operators of municipal waste water treatment plants. Everybody is requested to take a share in the solution and contribute with viable measures. Marjan van Giezen reported the first successfully implemented measures in The Netherlands: hospitals with a Pharmafilter to treat their waste water and patients using urine bags at home during the first days after leaving the hospital.

All-Frisian screw pump
Specialist in water technology and hydropower screw turbines, Landustrie, showed a special painted Archimedes screw pump at its booth. The screw was painted in the colours of the Dutch Frysian province. Landustrie uses the screw in strong flowing rivers to drive hydropower turbines. Hydropower screw systems have already been delivered to Austria, France, Germany, United Kingdom and even to the – very flat – Netherlands.

Networking reception at Dutch pavilion
The three organising parties of Netherlands water pavilion, Envaqua, Water Alliance and Netherlands Water Partnership, held a well-attended networking reception on the second day of the trade fair. Several exhibitors were given the opportunity to present their latest technology, including director Lex van Dijk (middle) of Bluetec who told about his new waste water treatment pilot with forward osmose.

Fancy built-in system for domestic water reuse
Hydraloop showed its residential water saving system at a special pavilion on water reuse and stormwater catchment. The fancy built-in system has the potential to reuse up to 85 percent of domestic water by cleaning and disinfecting waste water from the shower, bath and washing machine. The water can be reused for lavatory flushing, washing machine, garden irrigation or topping up the swimming pool.

What are they talking about?
Two exhibitors at the Netherlands Pavilion, Erik Roesink (left) of NX Filtration and Tom van Remmen of Van Remmen UV Technologies caught up in a conversation. Yes, it had to be about the additional treatment of effluent of a waste water treatment plant. The nanofiltration technology of NX Filtration has the ability to separate the wwtp-effluent in a clean fresh water stream and a concentrate that contains all micropollutants. Van Remmen has a solution for an additional treatment of the concentrate by advanced oxidation, using UV-light in conjunction with hydrogen peroxide oxidant. Both agreed their technologies would be an ideal match.

Joint German-Dutch 'Green-Blue Living Labs'
Hosted by the Consul-General of the Netherlands in Munich, Peter Verweij, Dutch and German companies interested in joint projects met at a circular economy breakfast meeting on 17 May. Both in Germany as in the Netherlands, many environmental technology suppliers are small SME-companies. The breakfast meeting had been organise to bring them in contact and talk about possible to participate in joint ‘Green-Blue Living Labs’ projects in urban environments.

Special pavilion for start-ups
For the first time IFAT had a special pavilion for start-ups, under the banner of Experience.science.future. One of the exhibitors at the pavilion was the Dutch-based start-up SenZ2. This company showed a ground breaking small blue box for online measuring of water levels in mm accuracy. The box used radar technology, combined with the connectivity of Internet-of-Things (IoT). Here seen is director Martin van Rijn showing the blue box, on top is a barrel with water treatment chemicals.

Live presentations on flux enhancement with Helix membranes
Every day Pentair X-Flow’s r&d manager Jens Potreck gave a live presentation on the Helix-membranes that have been developed by Pentair X-Flow. By enhancing the turbulence right at the entrance at the membrane wall, the Helix technology provides a higher flux, increases flow, and saves energy. Potreck showed the results of the Helix UF-membranes that are already operational.

Smart water sensors
In line with many German exhibitors, Dutch supplier of water monitoring equipment, Royal Eijkelkamp, payed special attention to its devices with smart technology that supply 24/7 online insight in water flows and water quality. On their booth. Eijkelkamp showed its automated Divers sensor for monitoring groundwater levels, as well as its Spectral-8 (UV/VIS) datalogger-sensor set for real-time optical measurement of BOD, COD, TOC, NO3 at waste water treatment plants.

The next IFAT will take place from 4 to 8 May 2020.

IFAT 2018: Potential of renewable nutrients from sewage sludge left untouched https://www.dutchwatersector.com/news-events/news/31531-ifat-2018-potential-of-renewable-nutrients-from-sewage-sludge-left-untouched.html dws-ifat2018-run4life-zeeman-770px-1
In Germany there is not enough capacity to recover nutrients from sewage sludge. Although many municipal waste water treatment plants are required to recover phosphate from their sludge, the real recovery is left untouched.

‘There is currently too little capacity to do so and the sludge is now stored’, revealed Christan Kabbe of Ilse Utilities at the opening of a special workshop of the EU Run4Life research project at the IFAT trade fair in Munich on 17 May.

Kabbe showed pessimism about a rapid improvement. ‘The German law on nutrient recovery can be changed overnight. This uncertainty makes the waste treatment sector reluctant to invest in additional recovery capacity’, Kabbe said at IFAT.

The situation in Germany is not an isolated case. In Switzerland the mandatory phosphate recovery leads to the storage of struvite. In the Netherlands the recovery is not yet mandatory and recovery projects do not scale up.

dws-ifat2018-run4life-gysin-ostara-350px  Ostara's Andrea Gysin explained the success of her company as it sees itself as a fertilizer company, not as a supplier of sludge treatment technology.

Involving fertilizer sector
The big problem is that the fertilizer market is reluctant to take up renewable nutrients. The only success reported at the Run4Life meeting was by the Canadian company Ostara.

According to Andrea Gysin, Ostara can operate successfully because it sees itself as a fertilizer company. ‘We now have 14 factories operational worldwide where we produce our carefully developed Crystal Green struvite from sewage sludge. Our big challenge is now to upscale the volume’.

Gysin told that her company has found a niche market in selling its Crystal Green to potatoes farmers. ‘We can develop more such niche crops but we can also increase the blending of our product in compost.’

Decentralized treatment
Gysin identified the problem of the small struvite volumes produced at each waste water treatment plant. Ostara sees it as a challenge to bring together these volumes.

At the same time, the Run4Life project looks at possibilities to treat sewage water more locally, at district level. On this topic two Dutch participants of the Run4Life project contributed with a presentation.

Brendo Meulman of Desah explained that his company has been active for ten years in the construction of decentralised treatment plants, based on the separated collection of grey waste water (from showers, washing machines and washbasins) and black water (from toilets and kitchen).

dws-ifat2018-run4lifew-meulman-350px Director Brendo Meulman at Desah told that after ten years of small decentralised treatment plants, the market is finally picking up to the +1000 inhabitants scale the Desah-technology needs commercially

Specialized sales companies
In his presentation Meulman identified the most important issue in his view: ‘We can think of the most fancy projects, but we cannot scale up if nobody wants to sell or to buy our recovered products’.

Desah participates in the Run4Life project to develop a closer relation to companies that sell the recovered products. Meulman: ‘We are involved in the grey water reuse and black water treatment at four selected demo locations. There we want to achieve 90 percent fresh water re-use and 90 percent nutrient recovery.’
The locations are in Helsingborg (Demark), Gent (Belgium), Vigo (Spain) and Sneek (the Netherlands).

Ground-breaking nutrient recovery strategies
Senior consultant Grietje Zeeman (on top photo) of the Dutch-based foundation Leaf gave a presentation on the development of new technologies to treat separated grey and black water streams.

Zeeman introduced the new Run4Life demonstration project to start in Sneek, the Netherlands. ‘At the current decentralized plant in Sneek, we cannot link the effluent of the anaerobic sludge reactor directly to our struvite reactor. First we need to remove the nitrogen’.

She pointed out that the current vacuum toilets still produce too high volumes of black water. ‘By using the newest ultra-low flushing toilets we can reduce the water use from 3 to 2 liters per flush. This enabled us to develop a new concept at the Wageningen University to produce calcium-phosphate granules inside the UASB anaerobic reactor. With less black water volumes, we can increase the temperature in the one-step reactor and use hyperthermophilic fermentation technology.

Zeeman told that the Run4Life project will also test a new technology of the Spanish demonstration side in Vigo. ‘At the office complex there, we will use a bioelectrical technology that is currently under development. We hope to be able to recover nitrogen from the reactor effluent, producing potassium fertilizer’.

World Menstrual Hygiene Day: help us to end this taboo! https://www.dutchwatersector.com/news-events/news/31541-world-menstrual-hygiene-day-help-us-to-end-this-taboo.html dws-menstrual-day-770px
Taboo, a lack of information, privacy and sanitary facilities, means that 70 percent of the girls in eastern and southern Africa miss one to three school days a month due to menstruation. Women and girls are seen as unclean during their menstruation period and are often excluded from school, family life, work and other social activities. 

Even in progressive societies, there is much shame about the monthly menstruation cycle. Women around the world hide their tampons and sanitary pads. Women's periods should be the most normal thing in the world. Therefore, today is Menstrual Hygiene Day. Because only by being open about menstruation we will break the worldwide taboo and go beyond shame.

Join Simavi that will start a series of webinars or on the campaign #Beyondshame.

dws-simavi-snv-menstrual-day-pinky-350px Pinky Devi (right with camera) made a video on how she broke the taboo in her Indian village and got involved in workshops (see her video below).

Weekly webinar on menstruation issues
On 31 May a series of five weekly webinars will start with different topics every week. The series aim to touch on many of the complex aspects of MH, including evidence, knowledge, menstrual products, infrastructure and policy.

The first webinar is 'Menstrual hygiene: the issue, evidence and gaps' and starts on 31 May at 12.00 UCT.

Participants learn about key opportunities and gaps regarding menstrual hygiene globally, particularly menstrual health as a cross-cutting theme. Furthermore, participants will be inspired to apply evidence informed programming in MH to ensure maximum impact.

Live broadcast from New York
The fifth and last webinar is planned to be a live broadcast from New York where a side event on this issue will take place during the High Level Political Forum on the Sustainable Development Goals at the headquarters of the United Nations.

The broadcasting of the whole series of webinars is a join production by Menstrual Hygiene Alliance, Wash United, WorldVision, Simavi and GIZ.

All webinars are free-of-charge and open to all interested professionals and individuals from all sectors.

Egyptian-Dutch panel identifies next steps in integrated coastal zone management https://www.dutchwatersector.com/news-events/news/31481-egyptian-dutch-panel-identifies-next-steps-in-integrated-coastal-zone-management.html dws-egypt-delegation-visit-oasen3-770px
An Egyptian delegation visited the Netherlands for a series of meetings with Dutch experts on a variety of water issues that urgently need to be addressed by Egypt. These issues included integrated coastal zone management (ICZM), rural waste water treatment and agricultural water management.

The delegation had been invited by the Egyptian-Dutch water panel to participate in the expert meetings with the Dutch water sector and site visits on 14 and 15 May.

dws-egypt-delegation-coast-alexandria-350px  Coastal restoration to protect the Qaitbay castle in Alexandria, Egypt.

Coastal restoration
During one of the joint sessions the Egyptian-Dutch panel discussed the issue of coastal zone management, identifying the next steps for Egypt to integrate its urgently needed coastal restoration and flood defence measures with other national development plans, including those for cities, ports and tourism and the environment.

The 1,000 km long Egyptian northern coast is vulnerable and prone to flooding, coastal erosion and pollution. Egyptian coastal authorities recognise these issues are also related to urban development, saline intrusion, agricultural and industrial water use and tourism.

Therefore, Integrated Coastal Zone Management has been on the agenda of the Egyptian-Dutch cooperation since 2014.

Major obstacles identified regarding the implementation of ICZM are the fragmentation of governance, lack of incentives for cooperation, lack of an adequate integrated legal framework and lack of clear responsibilities for the enforcement of legal regulations.

dws-egypt-delegation-oasen-raslan-350px Director Mamdouh Raslan at Holding Company for Water and Wastewater (HCWW) takes a closer look at the river bank infiltration station of water supply company Oasen.

Green climate fund project
In 2017, the Netherlands aided Egypt in its successful application for the Green Climate Fund grant for climate adaptation, including coastal zone management.

The fund approved a 31.4 US dollar million project by the United Nations Development Programme (UNDP) to protect Egypt's Nile Delta from rising sea levels due to climate change.

The project, 'Enhancing Climate Change Adaptation in the North Coast of Egypt’, will be implemented by the Egyptian Ministry of Water Resources and Irrigation over seven years.

The ministry will contribute 140 million Egyptian pounds to the project, which is centred around the construction of dikes to prevent flooding of homes and farmland due to rising sea levels and extreme weather due to climate change.

The project also includes the development of a ICZM plan and the establishment of a system to monitor changes in oceanographic parameters as an effect of climate change, as well as the impact of the different shore protection scenarios on the coastal erosion and shore stability.

dws-egypt-iczm-new-port-said-map-350px Impression of the coastal expansion plan for Port Said, Egypt.

New Port Said
The Egyptian delegation also talked about the plan for the outward expansion of Port Said, which comprises of land reclamation including coastal protection and economic prospects related to tourism and real estate.

The aim of the project is to protect Port Said through climate adaptation, while at the same time offering attractive development possibilities to public and private sector.

The Netherlands is ready to take on the role of trusted advisor for assistance and counselling for further project development involving all stakeholders and paying attention to social and sustainability issues.

About Egyptian-Dutch High-Level Panel
At the core of the Egyptian-Dutch cooperation is the Egyptian-Dutch High-Level Panel on Water Management. The panel meets twice a year: once a year with the water Ministers of both countries, and once a year with expert panel members.

The next panel meeting, most likely with the involvement of the water ministers of both countries, will take place in Egypt at the margin of the Cairo Water Week from 14 – 18 October 2018.

Witteveen+Bos to do feasibility study into bypass Itaipu dam, Brazil https://www.dutchwatersector.com/news-events/news/31509-witteveen-bos-to-do-feasibility-study-into-bypass-itaipu-dam-brazil.html dws-wibo-itaioudam-aerial-770px
Management company Itaipu Binacional has commissioned consultancy firm Witteveen+Bos to conduct a feasibility study for a bypass channel for shipping traffic passing the Itaipu Dam – one of the world’s largest hydroelectric dams, located on the border between Brazil and Paraguay.

The study focuses on bridging a height difference of 125 metres, using three or four locks, and comprises a technical design, an analysis of the environmental and social impact, and an economic cost-benefit analysis. The study also covers factors that determine the project’s social impact, such as stakeholder interests and environmental aspects.

The results of the study are expected to become available late July 2018.

dws-wibo-itaioudam-lake-side-350px Lake of Itaipu, as seen upstream of the 196 metres high dam..

Unparalleled capacity
The Itaipu Dam powers the world’s largest hydroelectric plant, which has an unparalleled capacity for the generation of renewable energy.

The dam is 7.7 kilometres long and its hydroelectric turbines generated 103 MWh of renewable energy in 2016, sufficient to meet 75 percent of the national energy demand of Paraguay and 17 percent of the total energy needs of Brazil.

Complex sustainability issues
To accommodate an increase in traffic over the past ten years, Itaipu Binacional decided to conduct a feasibility study into a bypass channel for shipping traffic near the Itaipu Dam.

Witteveen+Bos project manager Paul Ravenstijn: ‘We want to combine sustainable water management and energy generation with sustainable transport and economic development.’

dws-wibo-itaioudam-power-side-350px Seen on the downstream side, are the water pipes that feed 20 turbines, producing around 100 TWh electricity per year.

Key solutions
According to Ravensteijn rivers constitute vulnerable ecosystems, but they can provide key solutions for climate-related and environmental problems connected to energy production, food security and mobility.

‘This makes our feasibility study a complex undertaking that requires specialised expertise’, Ravensteijn explains.

Dutch prime minister Rutte supports Modi on goals for clean Ganges river, India https://www.dutchwatersector.com/news-events/news/31495-dutch-prime-minister-rutte-supports-modi-on-goals-for-clean-ganges-river-india.html dws-india-mission-ganga-forum-panel-770px-1
‘We need worldwide to value water, not only as an economic asset but also for its social, cultural, environmental, and of course, its religious value. All of which are so relevant when working on the holy Ganga river’, said Dutch prime minister Mark Rutte at the opening of the Indo-Dutch Ganga Forum in Delhi, India on 24 May.

He praised the Namami Ganga initiative by Indian prime minister Narendra Modi, aimed at cleaning the 2525 km-long Ganges river. The programme to prevent future pollution and to restore the river has a budget of Rs 20,000 crore (3.1 billion US dollars).

dws-india-mission-ganga-modi-rutte350px Indian prime minister Narendra Modi welcomed Dutch prime minister Mark Rutte as head of a large trade mission including four Dutch ministers.

Valuing water
Dutch prime minister Rutte headed a Dutch trade mission and spoke at the forum as a member of the UN-World Bank High level panel on water (HLPW) and leader of the Valuing water initiative.

On the occasion of the forum the Dutch prime minister stressed the need to recognise that clean and sufficient water cannot be taken for granted.

Huge river project
In 2014 the Indian government launched an integrated Ganga conservation mission called ‘Namami Gange’ to prevent pollution of the Ganges River and to revive the river.

Recently the Indian government announced to have started 195 projects for various activities such as improving and expansion of sewage infrastructure, landing steps to the river and crematoria development, river front development, river surface cleaning, institutional development, biodiversity conservation, afforestation, rural sanitation, and public participation.

dws-india-mission-ganges-haridwar-350px Special about the Ganges river is its religious meaning, here seen at the holy city of Haridwar.

Modernising ports and waterways
On the first day of the trade mission, Dutch minister for Infrastructure and Water Management, Cora van Nieuwenhuizen, attended the Indo-Dutch Forum on Smart and Sustainable Port-led Development in Mumbai.

‘India features a long coastline and an extensive river network that holds a great many opportunities for the logistics sector. In large sections of India, goods transport by water can be an ideal alternative to transport by busy roads,’ she pointed out in her opening address.

‘Dutch companies are eager to assist the Indian government in realising its ambition of modernising the ports and improving waterway connections to the hinterland’, Van Nieuwenhuizen added.

Urban planning on waste and waste water
Dutch municipality of Amsterdam concluded a Memorandum of Understanding during the conference. The Dutch capital will be collaborating with the State of Maharashtra in the fields of urban planning, waste management, waste processing, and water management.

IFAT 2018: Colsen presents water supply plant for company in dry running Cape Town, South Africa https://www.dutchwatersector.com/news-events/news/31472-ifat-2018-colsen-presents-water-supply-plant-for-company-in-dry-running-cape-town-south-africa.html dws-ifat2018-colsen-joop-770px
‘What can you do when you run an entertainment business just outside Cape Town when the city is running dry? One can hope for enough rain to refill the reservoirs and the water crisis to vanish? Or you can take the initiative to install your own water supply plant? The latter was the choice of our South African client’, says director Joop Colsen of water technology supply group of companies Colsen.

Earlier this year Colsen’s South African office, Aquest Colsen, commissioned a water treatment plant on the premises of the entertainment company, including 5 groundwater wells and a treatment plant with iron removal, sand filtration, reverse osmosis and stripping, for the delivery of 400 m3 per day.

dws-ifat2018-colsen-plant-cape-town-350px  Earlier this month Aquest Colsen started up a groundwater filtration plant for a commercial client near Cape Town, South Africa.

Start up treatment
Aquest Colsen closely follows the water crisis in the South African West Cape region.

According to director Joop Colsen (on top photo) many companies consider take matters into their own hands. Therefore Colsen was not surprised when the entertainment company asked them to build a water supply plant.

‘In September last year we started with the first preliminary studies and already by May we were able to start up the treatment’, adds Colsen.

Aquest Colsen designed a plant with a aerated sand filter to de-ironize the groundwater and managed to upgrade the RO-process to deliver 70 percent of the incoming groundwater as drinking water.

As final step the water is stripped to reach the right pH.

dws-ifat2018-colsen-ro-plant2 RO-modules deliver 70 percent of the incoming groundwater as drinking water.

Water supply for townships
On the occasion of the presentation of the new plant at the IFAT trade fair, Colsen reflects on the water crisis. ‘It is not only about climate change. The crisis is also a result of the increasing water demand’, he comments.

‘The South African authorities are upgrading all townships and thousands of new homes are being built, all with their own drinking water taps.'

'The water demand in Cape Town is rapidly increasing and the fresh water supply from the upstream water basins is no longer sufficient’, according to Colsen.

He foresees that it is inevitable Cape Town turns to desalination of sea water. In fact the South African office of Colsen has already been asked for preliminary studies for a desalination plant in the harbour of Cape Town.

Nine remaining design teams reveal final proposals to make San Francisco climate proof https://www.dutchwatersector.com/news-events/news/31453-nine-remaining-design-teams-reveal-final-proposals-to-make-san-francisco-climate-proof.html dws-rbd-san-francisco-winners-challenge2-770px-1
Nine teams have presented their final design to make specific areas in San Francisco more resilient to sea level rise, severe storms, floods and earthquakes. Together with local communities the teams made their final design public during a special meeting in San Francisco, USA, on 17 and 18 May.

In January the teams were selected as finalists of the Resilient by Design challenge and each was allocated to a specific area in the city. During the past months the teams had the opportunity to further develop their innovative ideas, involving the local residents, community organisations and public officials.

A jury approved all nine final concepts and they are now ready to be implemented and catalyse action. Three teams include Dutch firms.

dws-rbd-san-francisco-winners-ovink-350px Dutch water envoy Henk Ovink addressed the Resilient by Design community on the issue of urgency and to start acting.. Connecting creeks to the bay

Last year, the design challenge started off with over 30 international teams of which 10 got 250.000 dollars each to further develop their ideas. Several ideas concerned the restoration of creeks that flow into the bay, to restore water front and to create space in up-hill areas to store rainwater.

Now, a year later, the final design concepts are ready to be shared - each meant to inspire, catalyse action, and push the Bay Area along the path to a more resilient future.

The projects have networks of community organizations, city officials, local electeds, designers, engineers, scientists, and other experts that have been activated and inspired to work together to continue to move each project forward.

dws-rbd-san-francisco-winners-one-islais-350px Final design by the Big+One+Sheerwood team for the Islais hyper creek. Dutch participation

The three projects with Dutch participation are:
● Islais Hyper Creek, San Francisco County
Final design by Danish-Dutch team of BIG, ONE and Sherwood to restore the Islais creek and create a watershed, absorbing millions of gallons of storm water annually while providing multi-level ecosystem benefits. Public spaces along the swimmable riparian corridor offer recreational amenities, reconnecting the area to its historic waterfront.
● Resilient South City, San Mateo County
Final design by Australian-Dutch team Hassell+ and Deltares/ MVRDV/Goudappel to manage the flooding along Colma Creek by widening and greening the canal as well as creating a sequence of new parks, connect the community along the creek to the shoreline, between a series of active public spaces including a new waterfront pool.
● Unlock Alameda Creek, Alameda County, Public Sediment
Final design by SCAPE Landscape Architecture and Arcadis links the Alameda creek with the baylands to provide a sustainable supply of sediment to the baylands for sea level rise adaptation, reconnects migratory fish with their historic spawning grounds, and introduces a network of community spaces that reclaim the creek as a place for people.

Arcadis designs tunnel under Suez Canal in Egypt https://www.dutchwatersector.com/news-events/news/31443-arcadis-designs-tunnel-under-suez-canal-in-egypt.html dws-arcadis-ismailia-tunnel-impression-770px-1
For the second time design and consultancy firm Arcadis helps with the realization of a tunnel under the Suez Canal in Egypt. After the Ismailia Road Tunnel, Arcadis is now working on the three kilometer long tunnel under the canal at Suez.

Client of Arcadis is a joint venture between Egypt based companies Petrojet and Concord for Engineering and Contracting. The end client is the Ministry of Defense represented by the Engineering Authority of the Armed Forces (EAAF).

Acradis announced the project on 21 May.


dws-arcadis-ismailia-tunnel-canal-ships-350px  As part of the Suez Canal Corridor Development Project three new tunnels will be constructed underneath the recently widened and deepened canal. Concept to detailed design

The tunnel consists of a tunnel tube with a diameter of 13 meters at a maximum depth of 40 meters below ground level.

Arcadis is to deliver the complete design from concept to detailed design for the tunnel construction including the alignment, launch and receiving shaft, intermediate inspection and ventilation shafts, cross passages and highway design.

The design project also includes all MEP systems, such as ventilation, light, communication, pump systems and a fixed firefighting system.

Two TBM boring machines

The tunnel, with two parallel tunnel tubes will be constructed as a TBM drive with two tunnel boring machines with a 13.0 meters diameter.

The total TBM length will be about 4.7 kilometers, excluding the connecting ramp structures.

dws-arcadis-ismailia-tunnel-dredging-boskalis-350px The widening and deepening of the Suez canal was completed in Augustus 2015 and involved Dutch dredging companies Van Oord and Boskalis. Technical tunnel expertise

‘It is an honour to be able to continue working on such a project under the Suez Canal for the second time,’ says General Manager Gert Kroon of Arcadis in the Netherlands.

According to Kroon his firm was called in again as its technical tunnel expertise proved of great value at the Ismailia Road Tunnel. ‘We've shown that all our different business units work well together. There was enormous time pressure on the construction of the first tunnel and we quickly delivered a robust design’, Kroon adds.

‘Colleagues from different European countries are involved and we are ready for this second tunnel.’

Suez Canal Corridor Development project

The Ismaïlia Road Tunnel project is part of the investments made in the context of the Suez Canal Corridor Development Project.

In addition to the construction of the new Suez Canal a rail and road tunnel will be constructed at three locations (Port Said, Ismailia and Suez).

The Ismailia Road Tunnel is located in the vicinity of the town of Ismaïlia, halfway between Port Said and Suez alongside the Suez Canal.

This news is based on the original project presentation on the website of Arcadis.

IFAT 2018: How Nijhuis links tasteful mint to waste water https://www.dutchwatersector.com/news-events/news/31428-ifat-2018-how-nijhuis-links-tasteful-mint-to-waste-water.html dws-ifat2018-nijhuis-waste-taste-mint-box6-770px
Visitors of IFAT 2018 may have wondered why Nijhuis Industries showed a washing table, an urinoir and a stack of three growing boxes with mint herbs on their booth: to make the Radler beer more tasty.

The setup demonstrated the special concept developed by Nijhuis Industries to turn waste water into taste.

dws-ifat2018-nijhuis-booth-350px  The packed booth of Nijhuis Industries at IFAT 2018.

Circular sanitation concept
Waste-to-taste is a circular sanitation concept that utilises space technology with modular plug-and-play elements to treat separately collected human faeces (black), urine (yellow) and household washing water (grey).

After treatment the water can be re-used and the remaining fertilizer can be used to grow food.

Nijhuis Industries developed the concept (on top photo at the IFAT-booth) together with startup Semilla for cost-effective sanitation hubs in remote places and disaster areas.

The ‘water-to-taste’ concept fits in the growing portfolio of Nijhuis Industry offering a range of waste water treatment technologies to recover all kinds of valuable resources such as fat, ammonia, biogas and clean water.

dws-ifat2018-nijhuis-i-dose-350px The fully redesigned i-Dose  intelligent dosing control.

Nijhuis’ philosophy is that the recovery of these resources, not only results in less sludge and therefore less waste handling costs, but can also create income for the operator of a waste water treatment plant and lower the operational costs.

Next step in automation
Day-to-day fluctuations in waste water demand a flexible dosing of chemicals to achieve the discharge requirement, using as little chemicals as possible.

At IFAT Nijhuis Industries showed its latest step in process automation for dosing chemicals: the upgrade version of the i-Dose.

The new real-time monitoring system not only looks fancy in the well designed and colourful housing, it can save up to 30 percent on chemical consumption. The i-Dose consists of a UV-vis spectrometer, control & algorithm, monitoring system and automatic cleaning mechanism.

IFAT 2018: Paques presents compact version of its Astrasand continuous sand filter https://www.dutchwatersector.com/news-events/news/31409-ifat-2018-paques-presents-compact-version-of-its-astrasand-continuous-sand-filter.html dws-ifat2018-paques-hayward-sandy-770px
At this year’s IFAT, water technology supplier Paques launched a much smaller version of its continuous self-cleaning Astrasand sand filter. By redesigning the typical cone that contains the sand bed, Paques managed to reduce the height by one third, resulting in several advantages, one of which is 20 percent less energy use.

To mark the launch of the Astrasand Compact, Keith Hayward (left on top photo) of Paques handed over a model version of the filter to Sandy, one of the firm’s four ‘bacteria’ mascots that are always present at trade fairs.

dws-ifat2018-paques-astrasand-leeuwarden-350px  The first compact Astrasand filter is now opertional at an industrial site in Leeuwarden, the Netherlands.

Multiple sand cones
‘Size does matter’, says Keith Hayward, business development director for sand filters at Paques. ‘It has been a longstanding idea to develop a version of our Astrasand filter that is less high, but the engineering proved to be difficult. Now we have finally succeeded. The main change is the replacement of the traditional single cone, by multiple smaller ones.’

According to Hayward the advantages are numerous. ‘As the filter is substantial smaller, it fits into many existing buildings, making it possible to be placed inside. This is a real advantage for many industrial clients.'

More flexible control
‘By operating with smaller cones, there is more flexibility to control the filtration process, compared to a traditional single cone version. It improves the sand velocity distribution, lowering the risk of plugging of the filter bed’, Hayward explains.

The smaller version also means less use of material and less energy consumption, particularly by the pumps, which lowers overall life cycle costs.

Same process
‘The filtration process stayed the same, so the new compact version builds on Paques' history of proven and reliable sand filtration technology’, Hayward assures.

‘We have some 35 years of experience in providing sand filtration and can point to some 3,500 installations we have built worldwide. This is a truly innovative development of a well-known and trusted filtration process’.

The first compact Astrasand is operational at an industrial plant in Leeuwarden, the Netherlands.

Speakers from German, Dutch and French ministries shared their experiences on the development of a national strategy to prevent micropollutants from getting into the surface water and on how they engage all stakeholders involved, such as producers of chemicals, the pharmaceutical sector, hospitals, consumer groups, water quality authorities and water suppliers.

dws-ifat2018-micro-pollutantswagner-350px  Jorg Wagner of the German environmental ministry explained that his government is working step-by-step towards waste water regulations for micropollutants.

Most speakers were convinced that in the end an additional treatment - a fourth step - at waste water treatment plants is inevitable, but at this stage it is difficult for water technology suppliers to develop new technologies as there are no national or European effluent standards for micropollutants yet.

Bettina Doeser, head of unit clean water of the European Commission, updated the forum on the latest water regulatory developments in Brussel. She mentioned that early next year the European Commission will announce its plans for the revision of the Water Framework Directive. Doeser did not go any further into the commission’s plans on micro-pollutants.

At the forum the regulatory example of Switzerland was often mentioned. By national law 100 Swiss waste water treatment plants have been ordered to build a fourth treatment step and the first ones are now being extended with additional ozone filtration.

Germany, the Netherlands and France are clearly not yet ready for such legislation. The presentations made clear that the three countries are still in de middle of the process to talk with all stakeholders. ‘We do it step-by-step’, said Jörg Wagner of the German environmental ministry. ‘We are now in the process to operationalise our national policy strategy on micropollutants in two main elements: a new regulation for waste water and a publicity campaign’.

dws-ifat2018-micro-pollutants-giezen-350px Marjan van Giezen (middle) of the Dutch ministry briefed the forum on developments in the Netherlands where the first fourth stage wwtp expansions are now being planned.

According to Wagner it is impossible for the national government to prescribe an additional fourth step for all 6,000 municipal waste water treatment plants in Germany. ‘The costs have been estimated at 50 billion euros that is a no-go for the current German coalition government’.

First achievements at hospitals
On behalf of the Dutch government Marjan van Giezen reported on the first achievements, such as special urine bags for patients to take home when they come from a hospital.

Van Giezen also told that some Dutch hospitals installed a Pharmafilter to treat their own waste water, including a membrane bioreactor and a digestor for biogas production.

In the Netherlands several treatment technologies have been piloted and the Dutch government has earmarked 30 million euros to contribute to regional water authorities if they want to upgrade their municipal wwtp-plant.

dws-ifat2018-micro-pollutants-firk-350px Professor Wolfgang Firk of DWA explained the complexity of the establishment of regulations for the removal of micropollutant sfrom wastewater.

Polluter pays
In principal all three ministries share the policy of the polluter pays. But in negotiations with all stakeholders, they find it difficult to pinpoint the polluter. Is it the supplier of the medicines, the pharmacists or hospital or it is the user?

Professor Wolfgang Firk of the German Association for Water, Wastewater and Waste (DWA) stated that the issue is complex. ‘In the nineties we had similar discussions about additional treatment for the removal of nutrients'. Firk recalled.

'The costs were a manifold of what we are now discussing for the removal of micropollutants. But nutrients only concerned phosphate and nitrogen which are easy measurable. European effluent standards could easily be determined and regulation was quickly introduced.’

Firk was sceptical on the introduction of regulation for the removal of micropollutants as it is still unclear what specific substances cause the highest health or ecological risks and should be prioritised to be removed first.

The IBM grant allows TAHMO to use crowdsourced computing power through World Community Grid and weather data from The Weather Company, which are provided by IBM as part of its Corporate Citizenship program.

The Weather Company provides customized weather information to global commodity traders via its industry-leading WSI Trader website.

In return for this support, TAHMO will publish its African weather data publicly, thereby enabling the global community to benefit from and build upon their findings.

Rainfall modelling in Africa
According to professor Van de Giesen Africa is in urgent need of much more detailed rainfall modelling. ‘African rain storms are erratic and vary strongly from place to place, while many Africans rely on rain for their livelihood.'

Van de Giesen: ‘If we want to come to grasps with rain in Africa, we have to be able to make very detailed calculations of the atmosphere. Such calculations would not be possible with standard computers but IBM’s World Community Grid makes this possible.’

Van de Giesen suggests to divide the continent into many small areas, each area sufficiently small to be calculated by a single computer, so that rainfall throughout Africa can be determined with the necessary detail.

About IBM's World Community Grid
World Community Grid is an award-winning philanthropic initiative within IBM’s Corporate Citizenship program. Since 2004, World Community Grid has powered 29 research projects in critical areas such as sustainable energy, clean water, ecosystem preservation, cancer, AIDS, Ebola virus, and genetic mapping. This research is made possible by more than 740,000 individual volunteers and 430 institutions from 80 countries who donate unused computing power from their desktops, laptops, and Android mobile devices. 

TAHMO is a not-for-profit organisation that wants to realise a dense network of hydro-meteorological monitoring stations in sub-Saharan Africa; one every 30 km. This asks for 20,000 of such stations.

So far, TAHMO has deployed over a hundred of stations in schools in the African nations of Ghana, Kenya, Uganda, and Tanzania.

These beta weather stations have been developed over the past years in close cooperation with Meter Group (USA), with special attention to African conditions

Call for action: Come up with multifunctional designs to make three Asian cities more resilient https://www.dutchwatersector.com/news-events/news/31315-call-for-action-come-up-with-multifunctional-designs-to-make-three-asian-cities-more-resilient.html dws-rvo-water-leverage-colored-front-770px
Netherlands Enterprise Agency (RVO) calls on the global market to join their initiative ‘Water as Leverage for Resilient Cities Asia’ and to propose viable solutions for water problems in Chennai (India), Khulna (Bangladesh) and Semarang (Indonesia).

RVO challenges civil engineers, landscape architects, urban planners, non-governmental agencies, scientists and other key players, to form internationally operating multidisciplinary teams to start a pilot in one of the three cities.

The government agency has announced the rules for teams to enter the challenge and launched its first call on 26 April. Interested parties have till 18 June to submit their proposals.

dws-rvo-water-as-leverage-example-manhattan-350px   Example of a succesful design for the Rebuild by Design challenge in New York: a new waterfront for Manhattan.

Solving complex urban issues
It has proven to be extremely complex for cities to take measures to prevent damage caused by extreme weather events or to minimise their effects. Heavy rainfall, floods and droughts cause increasingly more economic and social damage.

Challenges in cities as New York and San Francisco have proven that by involving multidisciplinary teams, it is possible to mobilise citizens, and realise innovative and integral urban water projects that are developed and supported locally.

Such integral urban water projects can solve other issues as well, such as a better city planning, urban renovation, improvement of social coherence, protection of cultural heritage, recreation, air quality.

A water project that includes multiple infrastructural and social targets, can be a leverage for a impactful and catalytic change in tackling complex issues.

dws-rvo-water-as-leverage-exemaple-slum-bath-350px Certain parts of Asian cities need different designs to solve local water issues.

Call for transformative pilots
The Dutch government launched the Water as Leverage project to start a challenge for pilots in three selected Asian cities.

 The first phase started with the call for urban and water experts to form teams and come up with innovative solutions. The ideas will be judged on their bankability, innovation and multi functionality.

 Two financial institutes are involved in the project - Asian Infrastructure Investment Bank (AIIB) and the Dutch Development Bank (FMO) – to assist the teams on the financial aspects of their proposals.

 Each teams can make 3 to 5 different conceptual designs.

Awarded team get a predefined contract price of 200.000 euro to continue with phase 2.

Final proposals
Entering phase 2, the teams will be asked to transform their designs into final proposals for Urban Water Project(s) with a focus on physical infrastructure.

 RVO will organise local workshops in each city to bring together leaders of local communities, local experts and local government representatives.

The final proposals are expected to be ready by April 2019.

Salutions Collab joins Urban Farming Partners initiative on irrigation issues https://www.dutchwatersector.com/news-events/news/31293-salutions-collab-joins-urban-farming-partners-initiative-on-irrigation-issues.html dws-salutions-urban-farming-101-tower-770px-1
R&D specialist on fresh water supply to greenhouses, Salutions Collab, is to collaborate with Urban Farming Partners to set up their first urban farm in Singapore.

Urban farms will play an important role in increasing Singapore’s food security and Salutions Collab wants to contribute with its knowhow on the supply of irrigation water to ‘vertical’ greenhouses.

Farming concepts in Asian megacities
Urban Farming Partners is an initiative of Dutch experts in food, logistics and urban planning to setup urban farming concepts in megacities in Asia: from traditional horizontal greenhouses to vertical farming and roof-top agriculture.

Together with local partners, the consortium is well on its way to establishing the first urban farming concepts in Singapore.

In Asian cities the demand for fresh fruit and vegetables is growing rapidly while the space to grow these products is limited.

Urban farming connects to this trend with its short supply-lines from farm to consumer, guaranteeing fresh fruit and vegetables at all times.

Fresh water supply
Salutions Collabs now collaborates with Urban Farming Partners, strengthening the consortium with its know-how and expertise in supplying freshwater to greenhouses.

Rain-water harvesting, water reuse and aquifer storage and recovery (ASR) to balance water demand and supply, innovations developed by Allied Water’s Salutions Collab, will be fundamental in tackling irrigation water supply challenges.

About Salutions Collab
Salutions Collab is one of the R&D projects of Allied Waters, a public-private partnership (PPP) dedicated to implementing innovations in the urban water cycle that are ‘driving the circular economy’. The initiative reflects the Dutch water sector’s desire to create solutions to the key water problems, both within and outside of Europe.

About Urban Farming Partners
Urban Farming Partners, a group of experts in the fields of food, logistics, planning and architecture, are working together with the Dutch Government, to team up with partners in Singapore and investors on the issue of urban farming that has a high potential, especially in densely built-up areas like Singapore.

Universal access to water: ‘How do we make sure no one is left behind?’ https://www.dutchwatersector.com/news-events/news/31271-universal-access-to-water-how-do-we-make-sure-no-one-is-left-behind.html dws-irc-no-one-behing-ghana-650px-1
Universal access to water by 2030. The Sustainable Development Goal 6 on water is very clear. However, the task is huge.

‘Water has been acknowledged as a human right and this concept of universality and non-discrimination leaves us no room to leave anybody behind’, said Sara Ahrari of aid-organisation Simavi, speaking at a meeting on the topic in The Hague, the Netherlands on 18 April.

The meeting 'Leaving no one behind' was organised by IRC Wash to explore the framework that has to come in place to achieve this ambitious goal.

dws-irc-no-one-behind-ahrari-350px  Sara Ahrari of Simavi shared her experiences in Ghana on being inclusive in the WASH sector.

Making history
‘For a person who is working in the WASH sector’, said Ahrari, ‘it is a blessing that we are working in a period that we are making history.’ As a Senior Programme Officer for Simavi in Ghana, Ahari shared her experiences working with the Wamahinso community in the Ghana district of Asutifi North.

‘District, providers, supporting NGOs and the communities are partnering to implement a WASH masterplan’, she highlighted. The plan maps the district’s unserved and identifies the dilemmas that need to be overcome to ensure that no one is left behind.

Invisible groups
Ahrari specially mentioned the importance of including 'invisible' groups, such as the disabled. She noted that the taboo surrounding disability, led to under-reporting on the exclusion of the disabled.

On the ‘ínvisible’ group of the poor, she noted ‘Their reliance on daily wages, can prevent ultra poor’s participation in decision making when it comes to attending public meetings.’

dws-irc-on-one-behind-debate3-350pxgDifferent interpretations
Commenting on the existing legal framework of the United Nations for human right on water and sanitation, Ahrari explained that human rights can be interpreted differently.

As an example, she mentioned the Netherlands that acknowledges these rights, while in Belgium, India, Kenya, South Africa and Uruguay people can go to court to enforce them because they are included in their constitutions.

Economic or civil right
IRC Chair Robert Bos added some countries are reluctant to include the rights to water and sanitation in their constitution.

According to Bos these countries are unaware that the rights are part of the economic, social and cultural rights framework and not of the more contentious civil and political human rights framework.

Student Centaine Du Toy van Hees to represent The Netherlands at Stockholm Junior Water Prize https://www.dutchwatersector.com/news-events/news/31248-student-centaine-du-toy-van-hees-to-represent-the-netherlands-at-stockholm-junior-water-prize.html dws-waterhoofden-hees-blue-battery2-770px
Centaine Du Toy van Hees, student at RSG Magister Alvinus in Sneek, won the Dutch national qualification Knappe Waterhoofden, with her research on the Blue Battery, an electrical storage system on water and salt.

This allows high school student Du Toy van Hees to represent The Netherlands at the Stockholm Junior Water Prize 2018.

dws-waterhoofden-hees-winner-350pxThree different configurations
For her research on the best way to store energy in a acid-base salt fuel stack, Du Toy van Hees tested three configurations of her self-made bipolar membrane.

One configuration was a Battery Protection. Module (BPM) without a catalyst. The second was a module with an in situ catalyst.

The third – which proved to function best – was a module with an ex situ catalyst.

Michel Saakes of the water technology research institute Wetsus advised and trained Du Toy van Hees in the process of developing a membrane for the system.
