Dutch Water Sector https://www.dutchwatersector.com Dutch Water Sector Feed Scientists develop Beware-tool to asses flood risks along coral reef coast https://www.dutchwatersector.com/news-events/news/28809-scientists-develop-beware-tool-to-asses-flood-risks-along-coral-reef-coast.html dws-deltares-coral-reefs-aerial-770pxInternational scientists have developed a computer simulation tool to predict short-term flood hazards on coral-reef-lined coasts and to assess longer-term impacts from climate change. The tool is called Bayesian Estimator of Wave Attack in Reef Environments for predicting flooding (BEWARE) and can be used to understand the flood risks for low lying ocean islands that are often surrounded by coral reefs.

Scientists from Deltares, the US Geological Survey, and Delft University of Technology published an article about this tool in this month’s edition of the Journal of Geophysical Research: Oceans.

Damage to reefs
Hurricanes Harvey, Irma, Jose, and Maria became household names this fall as they tore a path of destruction through the Caribbean and southern United States.

The waves generated by such hurricanes or cyclones can have devastating effects on tropical island coasts fronted by coral reefs.

Many of these islands are low-lying (less than 3 m above mean sea level), with their freshwater in thin, fragile aquifers just beneath the surface of the ground.

This makes residents of such coastal areas extremely vulnerable to sea-level rise and flooding caused by waves, which can threaten their food and water supply, public health, and critical infrastructure.

Width variety of reefs
It is not easy to predict the flooding of coral-reef-lined coasts as there is a wide variety in physical structures.

According to lead author Stuart Pearson from Deltares and Delft University of Technology, the wave and sea level conditions vary significantly in space and time.

‘For many locations, there are little to no data available regarding these factors’, Pearson said. ‘The task of coastal flood prediction is made even more difficult by the complex changes that waves undergo as they move across coral reefs and approach the shore.’

dws-deltares-coral-reefs-scheme-wave2x-350px Reef profile as modelled in Deltares' XBeach.coastal modelling tool.

Tackling the problem
The Beware-tool can be of help in regions with poor data availability as it can generate an artificial database of wave conditions on coral reefs using the physics-based XBeach Non-Hydrostatic wave model.

This database is open-access and downloadable from the U.S. Geological Survey (USGS) database catalogue. Also look on the XBeach Open Source Community.

These data are compiled in a statistical Bayesian network model that enables the kind of fast predictions needed to power early warning systems for coastal flooding.

The Beware-tool will give input to estimate societal or economic risk and damage from such flooding. The tool can be used to play “what-if” games and ask questions such as, “how will flood risk change if the coral on this reef dies, or if sea level rises by more than 1 meter?”

Dutch-Ghanaian student team jointly worked on complex issues of Volta Delta, Ghana https://www.dutchwatersector.com/news-events/news/28796-dutch-ghanaian-student-team-jointly-worked-on-complex-issues-of-volta-delta-ghana.html dws-tud-ghana-wing-bus-770pxStudents and teachers from Delft University of Technology visited the Volta Delta and worked together with Ghanaian students of KNUST, Central University and University of Ghana, on integrated solutions for the complex issues of this river delta in Ghana.

The full week meeting included workshops and site visits in the river delta, focussing on a more strategic long-term response to climate change rather than on isolated engineering solutions. The visit was hosted and facilitated by the Ghana Wing of the Delta Alliance network organisation.

dws-tud-ghana-wing-boat-350pxWaterbed-like reactions
The Volta Delta is experiencing interacting problems due to a combination of climate change, coastal erosion, intensive urbanization and poor land use planning.

One of the major problems in Ghana is severe coastal erosion that affects coastal communities. Engineering solutions, such as the construction of groins and revetments have stabilized parts of the coast, but also blocked access to the beach, which is affecting traditional marine fishing activities, and have led to increased erosion of neighbouring areas.

In the lagoons, industrialization of salt mining and the development of intensive agriculture and unplanned urbanization put pressure on the delta’s ecosystem.

This competes with the traditional way of living of coastal communities and exaggerates the already poor livelihood of communities as a result of low fishing and agriculture harvests.

dws-tud-ghana-wing-busstop-350pxGuiding principles
The workshop funded by the Delft Deltas, Infrastructure and Mobility Initiative (DIMI) and Delta Alliance sought to improve the understanding of the complex challenges of the Volta delta and to develop guiding principles to support an integrated development that balances needs of local communities and economic development.

During one of the workshops, the Delft – Ghanaian student group developed long-term strategies based on the option of a managed retreat and relocation of the most vulnerable communities, a hold the line strategy by improved coastal protection, and a dynamic coast strategy, in which the sandy coast is maintained according to its natural dynamics.

Although the workshop did not aim to develop a comprehensive master plan, it helped to better understand the complexities of a delta that is urbanizing rapidly and that is threatened by climate change.

dws-tud-ghana-wing-beach-350pxKey findings
One of the key findings of the workshop is that it is absolutely necessary to better understand the natural dynamics of the delta and to better understand how the coastal system reacts to climate change.

Additionally, there is a strong need for both strategic long-term planning and new governance structures on the level of the delta to manage urbanization, coastal protection and other economic developments and the development of new economic activities to support a sustainable livelihood of the coastal communities.

Lastly, the lack of spatial planning and the community-focused culture brings in an element of complexity.

The workshop was funded by the Delft Deltas, Infrastructure and Mobility Initiative (DIMI) and Delta Alliance. A follow-up meeting will be held in Delft, the Netherlands, in April 2018.

Dutch-Indian partnership introduces less polluting tanning technology for cleaner Ganges, India https://www.dutchwatersector.com/news-events/news/28772-dutch-indian-partnership-introduces-less-polluting-tanning-technology-for-cleaner-ganges-india.html dws-solidaridad-ganges-ceremony-770px-1Three Dutch organisations, together with a number of Indian partners, launched a partnership to introduce a new, more environmental friendly, production process for the leather industry in India. 

The aim of the partnership is to reduce the effluent water discharged by at least 40 percent, contributing to a cleaner Ganges river. The three Dutch organisations are non-governmental organisation Solidaridad, leather processing product supplier Stahl and senior experts organisation PUM. The five-year project was launched in Kanpur on 13 November (see top photo).

dws-solidfaridad-stahl-tannery-kampur-350px  The aim is to reduce the effluent water discharge of the tanneries in Kanpur with 40 percent.

Overall water use
The project seeks to make the Kanpur Leather Cluster more sustainable by implementing new working methods and state-of-the-art technologies with a lower environmental impact.

It will address the overall water use and pollution from the Kanpur leather cluster, which is partly responsible for pollution loads in the Ganges.

Stahl will be established to demonstrate more sustainable technologies. In addition, there are activities for downstream communities about efficient water use for irrigation and livestock farming.

More sustainable tanneries
‘Solidaridad sees cooperation with tanneries and governments as the key to a cleaner Ganges’, says Gert van der Bijl, International Programme Manager Livestock & Leather at Solidaridad.

dws-solidaridad-ganges-go-leather-free-350px Protests against pollution of the Ganges river, made the Indian governement to start the Clean Ganga project.

‘Together we work on sustainable work practices for these tanneries. Solidaridad will introduce new technologies, business processes and trainings at all levels to diminish water use and pollution. Improving working conditions is an important focus’, Van der Bijl adds.

Complex water issues
According to Stahl the Kanpur leather cluster faces complex water issues. ‘Some 400 tanneries discharge 50 million liters of waste water each day’, explains Michael Costello, Director Sustainability at Stahl.

‘We alone cannot change the situation, so we have joined forces with industry partners and local authorities to contribute to the clean-up already underway of this iconic and sacred river,” says Costello.

The project is supported by The Sustainable Water Fund programme (FDW), a public-private partnership facility of the Dutch Ministry of Foreign Affairs.

Fairylike light reflections at night on closure dam Afsluitdijk, the Netherlands https://www.dutchwatersector.com/news-events/news/28748-fairylike-light-reflections-at-night-on-closure-dam-afsluitdijk-the-netherlands.html dws-afsluitdijk-roosegaarde-at-night-770px
Car drivers that enter the road on the closure dam Afsluitdijk at night, are welcomed by sculptures that reflect in their car lights. The fairylike reflection lights have been designed by Dutch artist and innovator Daan Roosegaarde and outline the monumental square constructions of the flood gates on each side of the road.

The line shaped design fits the iconic nature of the 32-kilomter straight dam that protects the Netherlands against floods since 1933. Car drivers can see the light sculptures each night till 21 January.

dws-afsluitdijk-roosegaarde-daylight-350px  The flood gates at the entrance of the 32 km long straigth closure dam in daylight.

New icon
For the occasion of the ‘Gates of Light’ exhibition the studio of Daan Roosegaarde has impregnated the flood gates with a new retro-reflective material that glows in the headlights of oncoming cars.

The flood gates have recently been restored as part of overall programme for upgrading the whole closure dam.

The Dutch government has embarked on a 850 million euro reinforcement plan to make the Afsluitdijk a new icon of Dutch flood protection.

Overflow-resistant and energy-neutral
The Dutch government opts not to raise the dam but to reconstruct it as an overflow-resistant dam.

dws-afsluitdijk-roosegaarde-portret-350px Artist and innovator Daan Roosegaarde is specialised in light art.

The owner of the dam, the national public work agency Rijkswaterstaat, wants to make the dam energy neutral.

Already existing energy supply stations along the dam that generate power, are an array of tidal turbines and a Blue energy pilot plant that generates electricity from the difference in salt concentrations between the fresh water on one side of the dam and the salt sea water on the other side. A plan for a 6,5 MW solar station is being studied.

A real novelty for the new Afsluitdijk will be a 5 km long artificial fish passage to allow migration between the Wadden Sea and IJssel Lake.

Groasis to supply Growboxx plant cocoons for UN campaign to eliminate hunger by 2030 https://www.dutchwatersector.com/news-events/news/28728-groasis-to-supply-growboxx-plant-cocoons-for-un-campaign-to-eliminate-hunger-by-2030.html dws-groasis-un-pilot-colombia-instructions-770px-1Dutch company Groasis will run a pilot project in Colombia to investigate the impact of its Growboxx plant cocoon that uses 90 percent less water to grow plants. The project is part of the UN’s World Food Proramme for ‘Zero hunger by 2030’. It combines ecosystem restoration and agroforestry, thus restoring degraded land.

The pilot to study the impact of the Groasis water saving technology will start in December. This summer the Growboxx was introduced in four Colombian villages (see top photo).

dws-groasis-un-pilot-colombia-watering-350px  Only one bucket of water can make a fruit tree grow in very arid areas.

Zero hunger
Groasis is part of the first cohort of 27 start-ups to receive support through the UN’s World Food Programme’s Innovation Accelerator.

The first selection beat competition from more than 100 start-ups who applied to the Global Impact Challenge, a joint call for innovations by Singularity University and the UN World Food Programme for “Zero hunger by 2030”.

Bold ideas
The competition seeks bold new ideas for quickly providing access to nutritious food for people living in hard to reach, eroded and disaster struck areas.

‘We are very honoured that we now have been selected as one of the winners’, said Pieter Hoff, founder of Groasis, ‘and to launch our first project with Wórld Food Programme. We share the same goal of achieving zero hunger’.

Less depend on aid
For the pilot on Colombia, Groasis provides the low-cost, scalable solution - the Groasis Growboxx® - which enables marginalized Colombians to grow their own fruit and vegetables thus lowering their dependence on aid.

The project focuses on the food production on degraded land with a promising water saving technology from Groasis, the Growboxx plant cocoon, which can be deployed on any type of soil and in any type of climate.

Less costs, less water and more crop
The Growboxx is a smart designed ‘bucket’ to collect water from rain and night time condensation in a reservoir.

The water is gradually released into the ground and stimulates the plant to develop a root structure. The box acts as a shield for the water in the upper ground and limits evaporation.

Groasis’ technology has already proven itself in more than 40 countries around the globe, offering 90 percent cost savings, 90 percent water savings, and a 90 percent survival rate of the trees and vegetables that are planted.

Groasis has installed the inexpensive, easy-to-use Waterboxx in many different countries, mainly to grow trees to combat desertification in arid regions.

Hand washing, soap and a clean toilet are needed to fight this silent humanitarian disaster. Sunday 19 November is World Toilet Day to raise awareness that toilets are of vital importance to the health of people around the world. 

dws-world-toilet-day-poster-350px1Selfie movement
In advance of the celebration several organisations have started a social media campaign. Dutch-based organisation Simavi launched a selfie movement and asks to send in your toilet selfies.

Simavi invites everbody to join the campaign, to take a good look at your beloved toilet and take a selfie. Tag @SimaviNL on Twitter, Instagram or Facebook and view the #toiletselfie of others.

Patrick’s poo
Dutch-based thinktank IRC Wash launched a film on the peoples need for proper sanitation systems. Not just the tiolet itself. ‘The film is hard-hitting and unpleasant’, says IRC director Patrick Moriarty. ‘But the status quo is worse, with a child dying every minute from diarrhoea or over half the world’s population still using unsafe sanitation.’

Patrick’s poo tells in a dramatised way that a toilet is just a hole full of sh*t, unless there is a sanitation system to deal with it. Let's put poo in its place. Permanently!

dws-world-toilet-day-irc-patrick-poo-350px IRC director Patrick Moriarty has his own way of telling that sanitation is more than a hole in the ground. It is a system. See the video below.

Create a sanitation economy
Multinational Unilever emphasises the possibility to turn sanitation into a strong economic sector that thrives on agile start-ups, governments and larger businesses working in collaboration.

On the Unilver-website Cheryl Hicks and Nitin Paranjpe look at how an innovative approach could transform society for the better, while also creating businesses and jobs.

As director of the Toilet Board Coalition Cheryl Hicks announces several projects that will be started in India to stimulate self-sufficient business models incorporating smart technologies such as pay-per-use wifi-hotspots.

Adequate sanitation for everybody
In 2013, the United Nations General Assembly officially designated November 19 as World Toilet Day. World Toilet Day is coordinated by UN-Water in collaboration with governments and partners.

The United Nations adopted the Sustainable Development Goals for 2030, including universal access to adequate and equitable sanitation and hygiene and end open defecation, paying special attention to the needs of women and girls and those in vulnerable situations.

We got the tools. Let’s make it happen.

VBA contracted to improve coastal defences at Fairhaven and Church Scar, UK https://www.dutchwatersector.com/news-events/news/28671-vba-contracted-to-improve-coastal-defences-at-fairhaven-and-church-scar-uk.html dws-vba-fairhaven-760pxJoint venture VBA, comprising VolkerStevin, Boskalis Westminster and Atkins, has been awarded a two year coast protection scheme contract by Fylde Council.

The 17.5 million UK pound contract will provide new coast protection at Fairhaven and Church Scar, south of Blackpool, as the current concrete defences, built in the 1890s, are in poor condition and require emergency repairs every year to prevent a major breach. Work is expected to start on site mid-January 2018 with completion in 2020.

dws-vba-fairhaven-st-anna2-350pxHold the line
The scheme is funded by the Environment Agency and is part of the North West Shoreline Management Plan to ‘hold the line’ here. On completion 2.425 properties will benefit from the new flood and erosion defences.

VBA will begin construction at Church Scar. Work will include piling, earthworks, pre-cast concrete revetment installation and concrete re-surfacing to the promenade, before starting work at Fairhaven.

As part of the protection scheme, a temporary bird roost will be created to avoid bird population disturbance to the natural ecology and environment.

dws-vba-fairhaven-boulevard-350pxEnhance promenade
Rob Coupe, managing director at VolkerStevin, said: ‘VBA has significant experience in coast protection and flood response and is delighted to be working closely with Fylde Council, to not only improve their coastal defences and protect homes, but to enhance the promenade experience for residents and tourists to enjoy, both now and in the future.’

Councillor David Eaves, chairman of the operational management committee for Fylde Council, said: ‘This is the largest capital project to be undertaken in the history of Fylde Borough Council. After all our hard work I’m delighted to see the contract now executed for the scheme.’

COP23: Launch of GCECA centre to speed up worldwide climate adaptation https://www.dutchwatersector.com/news-events/news/28618-cop23-launch-of-gceca-centre-to-speed-up-worldwide-climate-adaptation.html dws-cop23-gcecaq-launch-nieruwenhuizen-770px
At the climate summit COP23 in Bonn, the new centre of excellence on climate adaptation has officially been launched on 14 November.

The Global Centre of Excellence on Climate Adaptation (GCECA) aims to accelerate worldwide preparedness for climate change by getting a better understanding of climate adaptation, by stimulation of knowledge exchange and international collaboration worldwide. The centre will be based in Rotterdam and Groningen, the Netherlands.

dws-cop23-gceca-launch-solheim-hijioka-nieuwenhuizen-assy-350px Present at the launch event (left to right): Erik Solheim, (UN Environment), Yasuaki Hijioka (National Institute for Environmental Studies, Japan), Cora van Nieuwenhuizen (Dutch Minister), Elhadj As Sy (International Federation of the Red Cross Red Crescent Societies IFRC).

International collaboration
In the opening address, Mrs. Cora van Nieuwenhuizen, the newly appointed Dutch Minister of infrastructure and Water Management (on top photo), underscored the importance of international collaboration in the new centre and the uptake and exchange of knowledge.

‘There are many examples of adaptation, like the mangroves being replanted along the coast of Indonesia’, she said. ‘Or the way the World Meteorological Organization is using big data to inform African farmers with text messages when to plant and to harvest their crops.’

‘All these examples, all this knowledge is worth spreading all over the world. And that’s exactly what the Global Centre will do’, Van Nieuwenhuizen explained.

dws-cop23-gceca-launch-wallet-350px GCECA's Operations director Christiaan Wallet wants to make climate adaptation more measurable.

Paper into practise
Speaking ahead of the launch, Operations Director, Christiaan Wallet linked the demand for GCECA with the Paris Agreement.

‘We are grateful that the Paris Agreement has put climate adaptation on a par with mitigation but there is a long way to go. Understanding climate adaptation is crucial if we want to put paper into practice’, according to the centre’s operations director Wallet.

According to Wallet it will be important to learn what makes climate adaptation effective and how it can become measurable. ‘We need to understand to which degree the results of climate adaptation add up to meeting the global goals of the Paris Agreement and the Sustainable Development Goals’.

Wallet sees also an important role for his centre to unlock the large amounts of money already available and make it flow more direct to where it is needed most.

dws-cop23-gceca-launch-scheme-350px Key issues the GCECA centre wants to address.

Worldwide knowledge network
The centre will amass an ever-expanding network of international partners, among which leading knowledge institutes, businesses, NGOs, local and national governments, international organisations, and the financial sector.

Previously at COP23, GCECA supported the launch of UN Environment’s Adaptation Gap Report and held a side event, with Red Cross Red Crescent Climate Centre regarding measuring excellence in Climate Adaptation.

Looking beyond COP23, the Centre’s next engagement will be co-hosting the conference ’Towards a Resilient Financial Sector’ in London on 31 May 2018.

Many participants
The initiators of GCECA are the Dutch Ministry of Infrastructure and Water Management, UN Environment and Japan National Institute for environmental studies.

Other participating organisations include Acclimatise, Netherlands Environmental Assessment Agency (PBL), Partnership on Sustainable Low Carbon Transport, S&P Global, Delta Alliance, Deltares, Stockholm Environment Institute, Acclimatise, Netherlands Water Partnership, MCII, World Resources Institute, Wageningen University and Research Centre, UNEP DTU Partnership, SNV, Caribbean Community Climate Change Center, GEF, Adaptation Fund, The Nature Conservancy, NDC Partnership, Climate-KIC, Fundación Avina, African Climate Policy Centre, World Meteorological Organisation, Red Cross/Red Crescent Climate Centre, C40, Care, WWF, IDRC, Delft University of Technology, and IHE.

Landustrie to supply surface aerators for wwtp Jebel Ali in Dubai https://www.dutchwatersector.com/news-events/news/28596-landustrie-to-supply-surface-aerators-for-wwtp-jebel-ali-in-dubai.html dws-landustries-landy-adu-dhabi-750pxDutch Water technology supplier Landustrie received a 3 million euro order to deliver and install 48 Landy 7 surface aerators at the waste water treatment plant in the Jebel Ali district in Dubai.

The capacity of wwtp Jebel Ali will be increased from 300,000 to 675,000 m3 per day. The upscaling is needed to treat additional sewage water from a new housing area with 1 million inhabitants, the new airport and the World Expo 2020.

Landustrie will deliver its aerators together with gearboxes, motors and other accessories.

dws-landustrie-landy-7-dubai-scheme-350px  The Landy 7 aerators for wwtp Jebel Ali will all have a diameter of 2.4 meters.

Optimal oxygen transfer
Typical about Landustrie’s aerators is the axial flow design, allowing a high-efficient oxygen transfer in the aeration tanks of the treatment plant. This ensures a optimum microbial growth and removal of the organic materials from the waste water.

Both oxygenation and absorbed power are a function of the immersion depth, and increase slowly at larger immersion depths, allowing for a more flexible process sequence.

Due to the uniquely shaped blades, the LANDY surface aerators guarantee that the oxygen is evenly distributed across the full basin, thus eliminating sedimentation and dead zones.

In its own test tank in The Netherlands, Landustrie determined the best configuration to achieve the most efficient oxygen input.

dws-landustrie-jebel-ali-aerial-350px Wwtp Jebel Ali with the expansion under construction (right).

High temperatures
The treatment plant is located in open desert area, with temperatures rising in the summer months to well above 50 degrees Celsius. Therefore, the gearboxes driving the aerators will be provided with sunshields. The motors driving the gearboxes are designed to suit the high ambient temperatures.

The Landy 7 aerators will be installed in the following months under the supervision of Landustrie.

The delivery is carried out on behalf of the Belgian-Indian joint venture Besix - Larsen & Toubro.

The expansion project of the whole waste water treatment plant offered by the City of Dubai, comes to more than 300 million euro.

Utilising space-based assets and IoT technology, Blue Desert aims the development of an integrated monitoring & control service to assist customers in desert areas to manage groundwater resources.

Blue-Value is a consortium of two Dutch-based companies Rencos and 52impact, supported by International Groundwater Resources Assessment Center (IGRAC), Thuraya Satellites (UAE), SamTech Middle East (UAE) and the Netherlands Space Office (NSO).

dws-blue-value-desert-gorundwater-350pxGroundwater depletion
Global population growth and high water consumption in combination with severe climate change is resulting in catastrophic water shortages in many areas of the world.

For example, Abu Dhabi’s groundwater reserves are set to run out in 50 years if no action is taken (see top satellite image).

Simon van den Dries, co-founder of Blue-Value said: ‘The award of this project shows great recognition of the work done and the opportunity that we foresee here. It is vitally important that steps are taken to help us use water much more wisely and effectively.’

Real-time insight
Using IoT sensor data and satellite imagery and infrastructure information, the Blue-Value solution delivers real-time insight into water usage, quality and environmental effects.

This is all made available via an easy-to-use intuitive web application which is also available as a mobile phone app.

The integrated software solution enables services such as automated well monitoring, water abstraction metering and remote water pump control.

Water authorities and utilities can directly benefit from this service, enabling them to better manage the quantity and quality of the groundwater resource.

At the same time, the solution will enable farmers, miners, constructors and others to make better use of their water resource.

Nijhuis Industries awarded construction large industrial wwtp in Port Said, Egypt https://www.dutchwatersector.com/news-events/news/28519-nijhuis-industries-awarded-construction-large-industrial-wwtp-in-port-said-egypt.html dws-nijhuis-green-valley-oil-port-siad-impression-770px-1Green Valley Oil Services awarded Nijhuis Industries the order to deliver a turnkey wastewater treatment plant for the South Port Said Industrial Zone (SPIZ) in Port Said, Egypt.

The capacity of the plant is 60.000 m3/day – equalling 4 million PE - and will be delivered in two phases. Phase 1 will treat 35.000 m3/day and another 25.000 m3/day of industrial wastewater will be treated after the second phase, which is expected to be in operation in April 2019.

The industrial wwtp will be one of the largests in the world.

dws-nijhuis-green-valley-oil-alexandria-350px  Existing industrial wwtp of Green Valley Oil Services near Alexandria, Egypt.

Energy self-sufficient
The plant consists of Nijhuis’ technologies for the physical-chemical, aerobic and anaerobic biological treatment, active sludge and tertiary treatment, to meet the strict effluent requirements, and will also recover as much as possible biogas and energy from the effluent.

Based on the current composition of the wastewater collected from over 250 companies in the Port Said Industrial Zone the plant is designed to be self-sufficient on its energy demand, but will also sell access power to the grid, a true example of turning the cost for wastewater into profit.

Fifteen-year BOT contract
According to chairman and CEO Mr. Ahmed Ramadan at Green Valley Oil Services the contract marks the new policy of the Egyptian Government to work in public private partnership with industry together

Ramadan: ‘The fifteen-year BOT contract to operate this wastewater treatment facility is of very big importance to the GVOS Group and builds on our reputation to deliver solutions for environmental challenges.’

Tidal gate arrives at Ipswich flood barrier after crossing the North Sea https://www.dutchwatersector.com/news-events/news/28511-tidal-gate-arrives-at-ipswich-flood-barrier-after-crossing-the-north-sea.html dws-hollandia-ipswich-gate-arrival-770px
A 200 tonne tidal gate has arrived in Suffolk, UK, ready to be installed at Ipswich’s new flood barrier.

The delivery of the gate from its manufacturing site in Rotterdam, Holland, is a significant step towards the completion of the Environment Agency’s 70 million UK pound project. This reports the Environment Agency who is responsible for the new flood barrier to protect the port of Ipswich.

The work was carried out by Hollandia, a sub-contractor for Environment Agency contractor VBA – a joint venture between VolkerStevin, Boskalis Westminster and Atkins.

dws-hollandia-ipswich-gate-rotterdam3-350px The 200 tonne flood gate put on transport in Rotterdam, the Netherlands.

Heavy transport
It took 2 years to design and build the gate and 24 hours for it to be transported across the North Sea, finally passing under the Orwell Bridge and entering Ipswich early on the morning of Friday 27 October.

The gate is 22 metres wide and will stand 9 metres tall when it is in ‘closed position’. It is finished with 5 tonnes of special paint that will help protect it, as it spends most of its life under water.

Final elements
Project manager Andrew Usborne at Environment Agency, said: ‘This is a key milestone for the project and sees the final elements of the barrier arriving on site.’

dws-hollandia-ipswich-gate-work-350px Construction work on the flood barrier in the port of Ipswich, UK.

According to Usborne a very busy period has started for what has been a long-running project. The big crane has to be assemble on an island in the middle of the harbour to lift the heavy gate into place.

One in 200 year protection
The Ipswich Flood Defence Management Strategy (IFDMS) will increase the standard of protection to 0.33 percent (greater than 1 in 200) and takes into account current climate change predictions. The 0.33 percent relates to the probability of a combined fluvial and tidal flood event happening in any year.

The new scheme will reduce the risk of flooding to 1,608 homes and 422 businesses and support key infrastructure.

AIWW 2017: Look back at a productive event highlighting opportunities and alliances https://www.dutchwatersector.com/news-events/news/28463-aiww-2017-look-back-at-a-productive-event-highlighting-opportunities-and-alliances.html dws-aiww2017-photos0-rutte770px-1‘Industry, science, business, government and technology need to come together and act now’, said Dutch Prime Minister Mark Rutte at the opening of the 4th edition of the Amsterdam International Water Week (AIWW).

Rutte addressed the big challenge for the global water community to meet the water demand when the world population will reach the 9 billion mark by 2050. ‘The International Water Week is a great platform to forge new alliances’, he said.

By attracting over 20,000 visitors to the Aquatech Amsterdam trade fair and over 1,100 delegates to attend the AIWW conference, the event met the Prime Minister’s expectations to the fullest extent.

A remarkable output of AIWW 2017 are the nine Amsterdam Agreements, signed by case owners, experts, suppliers and investors to solve complex water issues and bring solutions to scale. They pledged to report back on their progress at the next AIWW in 2019.

The next Amsterdam International Water Week will take place from 4 – 8 November 2019.

Below a selection of photos, giving an impression of the whole event, including the conference and trade exhibition.

Crowd-puller: the Innovation Avenuedws-aiww2017-photos-01-innovation-avenue-770pxState-of-art water treatment technology had been gathered along one walkway. The Innovation Avenue was a big crowd-puller at the Aquatech Amsterdam trade fair that had a record breaking 928 exhibitors from around the world.

Amsterdam Agreements on breakthrough projects
dws-aiww2017-photos-02-aa-human-signing-770pxNine Amsterdam Agreements were signed by unique coalitions that – in the spotlight of the global water community – want to achieve breakthroughs. One of the agreements was signed by the public-private Human Cities Coalition that works on the improvement of the settlements in megacities.

Better valuing of water
dws-aiww2017-photos-03-rutte-ovink-suitcase-770pxThe value of water is more than just its price at the tap. Special Dutch water envoy Henk Ovink (left) travelled around the world to collect reactions on the concept of five principles that should lead to a better valuing of water, including environment, culture and local social circumstances. Ovink collected the reactions at the AIWW in a suitcase that he presented to Dutch Prime Minister Mark Rutte who is also a member of the High Level Panel on Water. In the coming months the panel is expected to adopt the principles.

Monetizing pee and poop
Dutch practitioner Samuel Sarphati came in from the afterlife and met the winners of the awards named after him. Sarphati collected excretes from toilets in Amsterdam some 150 years ago and brought it outside the city to use it as fertiliser to grow crops. Today award winners Sasha Kramer and Abhijit Banerji follow in his footsteps to monitize pee and poop as fertiliers to grow crops in Haiti and India.

Who's afraid of red, yellow and blue
Pump supplier Pentair Fairbanks Nijhuis displayed a split case pump painted in the typical cubic style of Piet Mondriaan. The famous Dutch painter started his career in Winterswijk where Nijhuis Pompen has its production location. This year the Netherlands celebrates the centenary of De Stijl abstract art movement with Piet Mondriaan as its best known member.

Water stress as driver of conflicts
Water scarcity may not be the only driver of conflicts but it surely is a powerful one. That was the message by the expert panel at a session on the avoidance of conflicts and migration. The water community can contribute by improving the availability of water in countries or regions where there is social unrest already and harvests are failing. Former Dutch water minister Melanie Schultz van Haegen (left at the table) called for defence ministers to get involved and prevent conflicts to escalate.

Great time for young water professionals
dws-aiww2017-photos-08-young-professionals-770pxYoung water professionals met ‘awesome waterholics’ from Mali, Czech, Norway, Columbia, US, Singapore, Australia, Oman, Germany, Korea, UK and the Netherlands. They had a great time discussing water issues in the ‘arena’ of their own pavilion.

Photoshoot city leaders
dws-aiww2017-photos-09-leader-forum-cities-770pxThe AIWW Conference had three Leader forums, one on the industry, one on the utilities and one of cities. The Cities Leaders Forum with representatives from over 50 different cities had a group photoshoot following their round table session. Cities realise they need to forge new partnerships with stakeholders, including business and citizens, to curve the linear water supply to a more circular one.

If we do not act….
A graph that says it all. It was presented by Lydia Whyatt, director of Resonance, specialised in advising institutional investors in asset investment funds. She showed the predicted increase of the water demand by the industry and the power sector (in Bric countries and worldwide) as a result of the expected improvement of the living standards for 9 billion people by 2050.

A rise of the sanitation economy boost payable and sustainable services for improved sanitation. Financial institutes need to recognise more the potential value of pee and poop as a source for biogas and nutrients. That was the key message at the Sarphati Award workshop that was attended by the award winners Sasha Kramer of SOIL and Abhijit Banerij of Finish.

The day prior to the workshop, both winners received the Sarphati Sanitation Awards during the Opening Ceremony of the Amsterdam International Water Week on 30 October. Deputy Mayor of Amsterdam, Alderman Udo Kock, handed out the Sarphati Sanitation Life Time Achievement award to Sasha Kramer and the Young Entrepeneurs Award to Ahijit Banerji.

dws-aiww2017-sarphati-old-new-350px The 'old' and the 'new' Sarphati: Doctor Samuel Sarphati (right) came in from the afterlife and met the award winner of 2017 Sasha Kramer of SOIL.

Exemplary work
The Jury decided to award Sasha Kramer (middle on top photo), who founded SOIL in 2006, for her exemplary work to provide sustainable sanitation services in Haiti, with an approach they considered to be replicable in many other situations, especially in fast growing peri-urban areas.

This year’s Sarphati Sanitation Award for Young Entrepreneurs, went to Mr Ahijit Banerji (seond left) of FINISH Society for his work as financer of sanitation and health projects in India.

On shoulders of giants
At the workshop Sasha Kramer reminded the attendants that the Amsterdam general practitioner Samuel Sarphati had already discovered the economic potential of faeces and urine some 150 years ago. As true entrepreneur, Sarphati had the faeces collected and applied as the fertilizer to crops on his estate and brought fruit and vegetables back to Amsterdam for the benefit of his patients.

According to Kramer today’s entrepreneurs in the field of sanitation, including herself, build their success on the shoulders of giants such as Sarphati.

However, there is still much to be done, Kramer said, referring to the 2 billion people in the world that still lack access to a clean toilet.

dws-aiww2017-sarphati-workshop-350px Two awards winners, Banerji (right) and Kramer (second right) joined the AIWW workshop on sanitation.

Unsafe facilities
Kramer told that many sanitation projects involve the construction of a centralized sewage system, or the construction of pit latrines in homes.

‘Neither meet the needs’, said Kramer. ‘and both lead to unsafe situations. In homes there is hardly space of a latrine and often the faeces are dumped just outside the settlements, leading to soil degradations.’

The disadvantage of a centralized sewage system is that there is hardly water to flush the system. And in case of extreme rainfall, the systems are vulnerable to floods and uncontrolled spreading of pathogens.

Kramer advocated Container-Based Sanitation (CBS) services using dry toilers that are specially designed for informal urban settlements and allow the transformation of the waste into valuable end-products, like SOIL’s organic compost.

Huge market potential
Award winner Ahijit Banerji mentioned the need to raise the awareness of the people living in the slums. ‘Our organisation Finish, focusses on the finance of sanitation services in India. For us it is important to aggregate demand for proper toilets and vendors that want to transport and handle the sludge’.

Finish realised 600.000 clean toilets in India since it started in 2010. ‘We see a huge market for sanitation’, Banerji said, ‘and social impact bonds can enable us to attract investors. However, we still concentrate on smaller towns where we understand the sanitation and waste markets better. The circumstances in big cities are too complex’, Banerji said.

A fish passage in a polder that only opens at a certain level of rainfall: This new fish migration system won the Wetskills challenge on 2 November. The winning team received their award from Nomvula Mokonyane, the South African Minister for Water and Sanitation during the closing session of the Amsterdam International Water Week Conference.

It was the fourth time the challenge for young water professionals took place in the Netherlands and was again hosted at the Amsterdam International Water Week.

dws-aiww2017-wetskills-talks-350px   Six teams were challenged to come up with a solution for a real case.

Mixed teams
For two weeks, 23 participants from around the world worked in mixed teams on cases of governments, companies, knowledge institutes and water authorities from home and abroad. Their goal: finding innovative solutions for current water-related challenges.

The participating students and young professionals came from all over the world, such as Oman, Egypt, India, Kyrgyzstan, Honduras, Israel, South Africa, and Indonesia.

They were guided by water professionals from the Netherlands.

New fish passage
The team that invented a new fish migration system was formed by Thijs Lieverse (Netherlands), Jelle Dijkema (Netherlands), Asandiso Mbewu (South Africa) and Radwa Elzeiny (Egypt) (from left to right on top photo).

dws-aiww2017-wetskills-poster-350px Solution of a fish passge that opens following a rainfall.

Thijs Lieverse commented on their solution: ‘Dutch regional water authority Waternet uses fish passages in their polders with a permanent opening. The problem is that you are continuously losing water and you have to pump back water to maintain the required water level.’

Rain as a solution
‘Our idea was to develop an event triggered system’, Lieverse continued, ‘so that only under certain conditions there is an opening for the fish to migrate. And what is a typical recurring event in Holland? Rain!’

The team designed a system for rainfall to raise the water level in the polder to a certain level. At some point, the system gets the signal ‘full’ and the passage is opened for a few days.

Next ‘Olympic’ edition
The next Wetskills challenge will take place in South Korea, early February, having the finals and awarding in the framework of the Olympic Winter Games. Bachelor, Master, PhD students and recent graduates can still apply for the ‘Olympic’ edition.

At every conference the young water professionals urge the governments and global water community to act. Their plea seems to have affect. At the Amsterdam International Water Week nine coalitions presented their ‘breakthroughs’ and signed the Amsterdam Agreement that promised to report back on their progress at the next AIWW Conference in 2019.

The AIWW Conference took place from 31 October until 1 November as part of the Amsterdam International Water Week. The conference was attended by 1,200 delegates.

dws-aiww2017-aa-residues-broere-olaf-vierssen-350px A coalition of three Dutch partners signed an Amsterdam Agreement to upscale the recovery and reuse of materials from waste water.

Finding a new concept
The idea of the Amsterdam Agreements is that coalitions are essential to solve the complex water issues of the future.

The conference had a focus on the world population reaching the 9 billion mark in 2050 and the subsequent sharp rise of the demand for fresh water. Not only for drinking water, but also for industry to make more products, for power station to deliver more electricity and agriculture to grow more crops.

Sharing successes and failures
The first nine Amsterdam Agreements that have been signed on 31 October show a wide variety of solutions and coalitions. It includes public, private and financial partners.

These partners are considered to be able to address best the future water challenge in a joint effort. The coalitions that presented themselves in Amsterdam are expected to show their progress to the world so everybody can learn from their experiences.

dws-aiww2017-aa-living-sea2-350px A coalition of also three Dutch partners will provide an experimental playground for new building practises on the coast.

Exploit opportunities
Dutch Prime Minister Mark Rutte underpinned the importance of the initiative. ‘Working together in the field of water is more crucial than ever. That is why we are here to exploit the opportunities water presents, but also to tackle the problems it creates.’

Rutte continued: ‘The Amsterdam International Water Week provides an excellent platform for government bodies, cities, industry, water companies, NGOs and next generation water professionals to create alliances, share knowledge and turn promising plans into practice.’

Discover roadblocks
Lennart Silvis, Chairman of the Managing Board AIWW and Managing Director of the Netherlands Water Partnership (NWP) highlighted the urge of organisers to give the conference more meaning. ‘The success of this conference is that we did not organise a traditional call for papers. We deliberately want to come up with concrete output and new partnerships, such as the Amsterdam Agreements.’


The already existing Human Cities coalition – founded by Dutch multinational Akzo-Nobel - agreed to share their experiences on their contribution to th UN New urban agenda by improving settlements in megacities such as Jakarta and Manilla.

The challenging part of the agreements is their follow up after the conference. ‘Part of the agreement is to keep us informed about the progress, the challenges, road blocks and successes, and increase the transparency which is required to make the next step in the global water world’, added Silvis.

Working towards an international movement
During this week the AIWW management board and a delegation from Singapore agreed on an intensive cooperation between AIWW and Singapore International Water Week.

The organisers of both conferences will intensify the sharing of experiences and contacts, as well as sharing the experiences and giving updates on the Amsterdam Agreements next year at the conference in Singapore.

This way the AIWW is intended to gradually transform from an event into an international movement.

AIWW 2017: Sightseeing ‘hot stuff’ at Aquatech’s Innovation Avenue https://www.dutchwatersector.com/news-events/news/28348-aiww-2017-sightseeing-hot-stuff-at-aquatech-s-innovation-avenue.html dws-aiww2017-inno-avn-walkway-770pxA walk along the Innovation Avenue shows the world’s ‘hot stuff’ on water treatment technology. That is one of the new features at the latest edition of the Aquatech Amsterdam trade exhibition that has entered its final day.

Given the many visitors that daily stroll down the specially designed walkway, it has proven to be a real success.

The Aquatech Amsterdam trade exhibition is one of the major events of the Amsterdam International Water Week that takes place from 30 October till 3 November.

dws-aiww2017-inno-avn-molenkamp-350px  Director Hein Molenkamp of Water Alliance (left) calls innovation a trade mark for the Dutch water sector.

Extremely long walkway
Next to the latest technologies from the Dutch water sector, the walkway also shows the nominated solutions for the Aquatech Innovation Award, the carefully selected ‘cutting edge’ technology by the Irish-based market specialist BlueTech and the latest scientific research in the InnovationLAB.

The concentration of all this ‘hot stuff’ along the extremely long walkway, provides the visitors of Aquatech a good impression of the innovation trends.

New sensoring technology
Absolute key are the new multiparameter sensoring technologies to collect ‘big data’ that can be linked to all kind of process control and management tools.

Another trend clearly visible is the development of concepts that go beyond a single technical installation such as the recovery of energy incorporated in the electricity grid and the use of solid waste to produce more biogas.

The idea to create a special walkway with innovative water technologies, originates from the Dutch business facilitator Water Alliance.

    dws-aiww2017-inno-avn-schonewille-350px CEO Henk Schonewille of Wafilin Systems at the Innovation Avenue.

Innovation as a trade mark
‘For Dutch water technology companies, innovations are very important’, says director Hein Molenkamp of Water Alliance. ‘By bringing new technologies to the market, they can distinguish themselves in the world and stay in the lead in niche markets.’

One of the exhibitors at the Innovation Avenue is Wafilin Systems. CEO Henk Schonewille adds: ‘From the first day, it was clear that this dedicated walkway is a success. It is much more crowded here than elsewhere on the exhibition floor.’

Schonewille has an explanation for the success. ‘Most visitors do not come for yet another pump or filter. They are looking for new end user’s products and the most remarkable ones are here.’

AIWW 2017: Game-changing WWTP-technology CoRe Water launched at Aquatech https://www.dutchwatersector.com/news-events/news/28317-aiww-2017-game-changing-wwtp-technology-core-water-launched-at-aquatech.html dws-aiww2017-core-water-signing-770px
On the first day of the Aquatech Amsterdam, Allied Waters, BLUE-tec, KWR and Royal HaskoningDHV signed a collaboration agreement for the further development of CoRe Water, a new technology concept that can radically change the treatment of municipal waste water.

The four parties believe it is time for a fundamentally rethought of the current treatment process that are designed to meet effluent standards. Resource recovery should not be a side-line, but the central trust of a production process.

The objective of the agreement is for parties to develop a process that aims to recover a maximum amount of energy and resources from waste water, and to radically cut emissions of greenhouse gases and pharmaceutical residues.

dws-aiww2017-core-water-fo-scheme350px   At the hearth of the CoRe water concept is a forward osmosis technology that draws out the water, leaving a concentrate for the recovery of energy and materials.

Concentration as first step
CoRe Water stands for an innovative concept: Concentration and Reuse. ‘As a first step, we will concentrate municipal wastewater by a factor of 20 applying forward osmosis,’ says Lex van Dijk, director of BLUE-tec.

The separation results in very clean water of a ‘demi’ water quality which is suitable for reuse in a number of applications. The concentrated stream (1 part of the 20) is then biologically treated – first anaerobically, then aerobically.

Maximum recovery
Danny Traksel, Business Developer at Royal HaskoningDHV explains: ‘In this way we can recover the maximum amount of energy and valuable components, while making the removal of pharmaceutical residues manageable. We also take huge steps towards limiting greenhouse gas emissions.’

Making the leap
The key technique applied is Forward Osmosis, a relatively new and promising technology which is now beginning to break through in water practice.

‘More than ten years ago, we started researching Forward Osmosis on a small scale and, little by little, we made progress’, says Emile Cornelissen, senior scientist at KWR. ‘Now, I look forward to making the leap to water practice with our partners’.

Van Dijk concludes: ‘With CoRe Water we’re now truly making the step from WWTP to water factory!’

dws-aiww2017-core-water-booth-7350px The foward osmosis installationin is displayed at the booth of BLUE-tec in Amsterdam.

In the presence of Dutch Prime Minister Mark Rutte, the prestigious Aquatech Innovation Award 2017 was handed out to the Dutch company CirTec that participates in the Cellvation system for the recovery of clean, marketable cellulose fibres from municipal waste water.

The award was handed out to Marite van Veen of CirTec during the Opening Ceremony of the Amsterdam International Water Week on 30 October.

dws-aiww2017-aquatech-award-cirtec-fibres   Clean and marketable cellulose fibres recovered from sewage water with the Cellvation process.

The Cellvation system has been developed by CirTec in partnership with the company KNN. CirTec is responsible for the fine sieve screen separation technology and KNN is responsible for bringing the recovered cellulose fibres to the market.

In The Netherlands a recovery installation based on Cellvation system is already operational at municipal waste water treatment plant Beemster, just north of Amsterdam, where daily 400 kilogramme of pure cellulose is recovered for different kind of applications.

Part of this cellulose is exported to England where it is used as a raw material to produce bio-composite.

High-profile showcase
The Aquatech Innovation Award wants to showcase the high-profile solutions offered by the exhibitors at the Aquatech Amsterdam trade exhibition. From a total of 78 entries 14 were selected as nominees for five different categories.

CirTec was selected by the jury as overall winner.

‘It is a good example of resource and is a perfect example of the circular economy in action’, comments jury chairman Cees Buisman (right on top photo), scientific director of Wetsus water technology centre.

dws-aiww2017-aquatech-award-cirtec-veen-350px Proud overall winner Marite van Veen of CirTec. 

Less sludge
The cited benefits of recovering the remains of the toilet papers when the sewage water enters the treatment plant included a reduction in energy and chemical costs for sewage treatment, along with a reduction in amount of sludge that is produced.

Furthermore, the cellulose is used as a technical product in applications such as road construction, offering an outlet for the marketable products derived from the Cellvation process.

‘It also means you have to cut down fewer trees, and the enormous amount of energy and chemicals that are used to convert a tree into cellulose can also be saved’, adds Buisman.

Opening AIWW 2017: Dutch PM calls for better reflection of true values of water https://www.dutchwatersector.com/news-events/news/28261-opening-aiww-2017-dutch-pm-calls-for-better-reflection-of-true-values-of-water.html dws-aiww-opening-rutte-770px‘It all comes down to one thing: valuing water’, said Dutch Prime Minister Mark Rutte at the Opening Ceremony of the Amsterdam International Water Week on 30 October.

Rutte told that he has lobbied for this theme as a member of the High Level Panel on Water (HLPW) in recent years. ´If we know what water is worth to each stakeholder, we can make the most of trade-offs and maximise the total value of water to society’, he said. Next to economic value, water also has cultural, social and environmental values.

The Dutch prime minister is one of the eleven sitting heads of states that form the panel initiated by the United Nations and the World Bank. The panel aims to mobilize global support for the implementation of the water-related Sustainable Development Goals (SDGs).

The Amsterdam International Water Week takes place this week and includes the international AIWW Conference and the Aquatech Amsterdam trade exhibition on water technology.

dws-aiww2017-opening-tuck-350px Laura Tuck, Vice President for Sustainable Development of the World Bank took a stand for girls and their future development that depends so much on the availibity of water.

Opening Ceremony
Prime Minister Rutte invited all 800 delegates that attended the Opening Ceremony to exploit the opportunities presented, but also to tackle the problems it creates. ‘The event provides an excellent platform for government bodies, cities, industry, water companies, young people and NGOs to create alliances, share knowledge and turn promising plans into practice’, he mentioned.

‘Climate, water, poverty - and all the other SDG themes - are interrelated’, Rutte said. ‘Trying to tackle them is like trying to solve a Rubik's cube. In the Netherlands, we always start with the blue side’.

Better reflection of value
Just prior to the Opening Ceremony, the High Level Panel on Water held a roundtable on the issue of valuing water where the recent revealed provisional five principles leading to the better reflection of the value of water as was mentioned by the Prime Minister.

The principles will officially be launched at the 8th World Water Forum in Brasilia in March and in the run up a team of experts organised roundtable sessions all around the world to collect comments for improvement.

The roundtable session in Amsterdam was one of the last consultations.


At a side event Willem Mak explains that valuing water is a constant process as the value changes in tme and place.

Conflicts of values
The consultation is Amsterdam showed that trust is an important element as the value of water changes in time and place. It also changes when different stakeholders are involved. To maximise the value it is important that stakeholders talk about trade offs to balance the different values. Trust was mentioned a crucial element when talking about who pays and who gets the benefits.

One of the examples given was the case of the Dutch beer brewer Heineken that built a production plant in Mexico and in order to compensate for the use of water, it planted a forest.

Another example was given from Mali where people are not accustomed to pay for water. Local authorities started an awareness campaign that the water  infrastructure costs money and that if the people pay for this service, the supply and the water quality can be improved.

Update version
At the Amsterdam International Water Week the revised version of the principles was presented. According to project manager Willem Mak at the Dutch Ministry of Infrastructure and Water Management, many consultations discussed the integration of the human right to water in the principles.

‘It was recognised that cost recovery is an important element for sustainable water supply’, said Mak in Amsterdam. ‘But many urged to keep water tariffs and taxes at affordable prices, also for the poor.’

The preamble of the five principles has recently re-edited and now addresses this issue and mentions: where tariffs and prices are used, safeguards are essential to ensure that access to water is available, equitable and affordable to all.

Meet the Dutch water sector
Part of the Amsterdam International Water Week is the trade exhibiton Aquatech Amsterdam where it is possible to meet the Dutch water sector at the Netherlands Pavilion booth 07.430 (hall 7). See the day-by-day programme on this website.

Lettinga Award 2017 for research on growing biomass in the dark using wastewater https://www.dutchwatersector.com/news-events/news/28232-lettinga-award-2017-for-research-on-growing-biomass-in-the-dark-using-wastewater.html dws-lettinga-award2017-770px
The winners of the Lettinga Award 2017 are assistant professor David Strik, PhD researcher Mathijs van der Zwart and professor Cees Buisman from Wageningen University, the Netherlands, with their research on the possibility to grow plants on electricity in a anaerobic bioreactor using the nutrients from waste water.

The winning project was announced at the well-attended closing ceremony of the 15th World Congress on Anaerobic Digestions in Beijng, China on 20 October.

The Lettinga Award 2017 was sponsored by water technology suppliers Paques and Biothane, as well as the LeAF Foundation.

dws-lettinga-award-2017-dark-photosynthesis-lab-350px Lab scale anaerobic bioreactor (left) with algae that grows on electricity and nutrients from wastewater. The solar collector (right) provides the electricity to make the algae grow.

Growing biomass in the dark
The three researchers at the department of Environmental Technology of the Wageningen University wrote a project proposal, entitled ‘Dark photosynthesis: anaerobic biosynthesis of food from wastewater and electricity’.

The idea of the project is that by dark photosynthesis, food is produced in a bioreactor in a water and energy efficient way.

Dark photosynthesis is an idea in which photosynthetic micro-organisms, such as algae, are grown in the dark while an electrode provides the electron donor and conditions needed for growth.

By providing a nutrient rich wastewater, high value biomass can be produced which is in potential food of feed grade.

The winners of the Lettinga Award hypothesize that they can create conditions which will also allow growth in the dark.

dws-lettinga-2017-buisman-350px Professor Cees Buisman of Wageningen University received the award in Beijing - also on top photo - and in his presentation he talked about the role of water in a biobased economy.

Urine as nutrient
With the award the winners will experimentally validate their ideas and use real (diluted) urine as primary nutrient. In this way they expect to open new doors of research on anaerobic biosynthesis technologies which use wastewater as raw feedstock.

The project proposal reflects this year’s call for the award that was on using anaerobic technology for closing resource cycles.

The judges who evaluated the proposals came from the industry and academia and were guided by the following criteria: scope, innovation and impact.

Most potential
The winning proposal was characterized by the judges as ‘the one with the most potential’.

With the award they will experimentally validate their ideas and use real (diluted) urine as primary nutrient.

In this way they expect to open new doors on research on anaerobic biosynthesis technologies which use wastewater as raw feedstock.

About the Lettinga Award
The Lettinga Award was initiated more than fifteen years ago by Dutch environmental technology suppliers to stimulate the development of anaerobic treatment technology.

Traditionally, the award is coupled to IWA Anaerobic Digestion congresses and is presented every two years.

The Lettinga Award was initiated in 2001 and has been awarded for six times now.
● 2015 – SimGas
Adding value to anaerobic digestion by development of a biogas powered milk chilling solution for East African smallholder farmers
● 2013 - Shiva Salek

The team, led by dr. Leon Korving (middle on top photo), received a cheque of 50.000 US dollar and enters the third phase of the competition. Together with the two other winners, the team will build a pilot version.

The winner of the third phase will receive a prize of 10 million dollar for full scale application in Florida.

dws-wetsus-barley-glades-poster-350pxRemoval and recovery
The Everglades Foundation launched the George Barley prize in their search to find cost-effective solutions to remove and recover phosphorus from surface water in their combat against toxic algae blooms in the Everglades and along the coasts of Florida.

In total 77 entries from all over the world started this competition on the most promising system to combat algae bloom in surface waters by removing low concentrations – 10 ppb - of phosphorus at low cost.

Minimal footprint and minimal costs
The competition challenged the entries to develop an new system with a very minimal footprint and at cost of less than 120 dollar/kg P.

Wetsus proposed their NaFRAd-solution which is a combination of flocculation with natural flocculants and reversible adsorption with high capacity iron based adsorbents. In this way both particulate and soluble phosphorus can be removed with minimal waste formation.

dws-wetsus-barley-phase-1-kumar-350px Wetsus PhD-researcher Prashanth Kumar received an award for the first phase on 22 March, in West Palm Beach, Florida.

Two other winners
Other winners of the Stage 2 awards are:
● second place for Green Water Solutions with their BioPhree-technology that decreases phosphorus concentrations to less than 10 ppb even under high-phosphorus inflow.
● third place for USGS Leetown Science Center with an environmentally friendly water filter system using a discarded mining byproducts, called mine drainage ochre, as the primary filtering agent to remove phosphorus from municipal and agricultural waste waters.

Bluerise nears crowdfunding target for first two OTEC projects on Curacao and Jamaica https://www.dutchwatersector.com/news-events/news/28134-bluerise-nears-crowdfunding-target-for-first-two-otec-projects-on-curacao-and-jamaica.html dws-bluerise-crowdfunded-launch-770pxWithin one day after Dutch-based company Bluerise started its crowdfunding campaign for its first project on thermal ocean energy on the Caribbean island of Curacao, it already reached the targeted 250.000 US dollar. After this success, the company has set itself a new goal of 500.000 dollar to be able to realise a second project on the Caribbean island of Jamaica.

At this moment the crowdfunding website states a result of 377.000 dollar and the campaign is still running. Bluerise started the successful crowdfunding campaign on 7 September (on top photo).

dws-bluerise-crowdfunded-scheme350px  Bluerise's B-TEC uses the 25 - 30 degrees lower tempersture at 1,000 m depth to generate electricity and to extract cold ocean water for cooling.

New OTEC-technology
Bluerise has developed a new Ocean Thermal Energy Conversion (OTEC) technology to generate energy from the ocean in the tropics.

OTEC-technology uses the temperature difference between the surface and deep layers to generate electricity. The energy production with OTEC is very constant, as the temperatures in the ocean hardly vary between day and night or even between the seasons.

This makes OTEC a very reliable source of energy that can be easily integrated into the electricity grid.

dws-bluerise-crowdfunding-amount-350px On 26 October the campaign website showed 377,940 dollar was raised.

Commercial roll out
The combination of a more efficient thermodynamic system with smart control systems form part of Bluerise’s B-TEC technology which can provide savings of up to 20 percent in costs per kwh.

In the tropics the surface water is 25 to 30 degrees, while the temperature is at 1,000 meters depth between 4 and 6 degrees. Bluerise uses this energy to produce sustainable cooling and electricity.

The company tested a demonstration size advanced OTEC power plant in which mixed working fluids are used and B-TEC is ready for commercial rollout.

In Curacao, Bluerise is working on a B-TEC project at the airport and in Jamaica it is intended to build a cooling plant for the local energy supply company New Leaf Power at the Montego Bay.

Cheaper cooling
Robert Wright, CEO of New Leaf Power, partner Bluerise in Jamaica: ‘Bluerise offers a clean and cheaper alternative by cold sea water 1,000 meters deep to pump up to cool our hotels. This cooling mode is 10 times more efficient, saving up to 90 percent of the energy.’

‘Ultimately, what our customers want, they want cheaper energy, cheaper cooling, that's clean and green’, said Wright.

dws-bluerise-crowdfunding-development-350px   Development of B-TEC at Delft University of Technology.

Energy saving on air conditioning
In the tropics, more than a billion people live near the coast. More than half of the energy goes to air conditioning. These air conditioners use a lot of expensive, non-sustainable electricity and provide a lot of CO2 emissions.

Cold water from the deep ocean is able to cool buildings at a much lower cost in a sustainable way. With the temperature difference between hot water on the surface and the cold deep water, electricity can also be generated day and night.

Because unlike solar and wind energy, ocean energy is always available and does not need to be supplemented by polluting energy at times when the sun is not shining or the wind is not blowing.

Deltares models impact of hurricanes that might head for Western Europe https://www.dutchwatersector.com/news-events/news/28071-deltares-models-impact-of-hurricanes-that-might-head-for-western-europe.html dws-deltares-ophelia-londonderry-770pxDutch research institute Deltares ran some simulations of hurricanes that develop in the warm waters of the African coast. Instead of crossing the Atlantic Ocean heading for the Caribbean, the hurricanes may divert more often to Europe and follow the path of hurricane Ophelia two weeks ago.

Delatres investigates the effects of such hurricanes to get a better understanding of the potential storm surges when reaching the European coast. The runs show that especially Ireland and Great Britain are in the firing line.

See below animations of potential storm surges.

Still a rare phenomenon
At present, hurricanes are a relatively rare phenomenon in Europe because of the colder seawater temperatures in this area.

However, Hurricane Ophelia, which reached Ireland (on top photo) in the form of a severe storm/depression on 16 October this year, inflicted severe damage, causing floods and even fatal casualties in Ireland.

Although this was one of the most severe storms to reach Europe in recent decades, the future may have worse in store. Research institute Deltares ran a simulation last week to show the effects of possible hurricanes in Europe in the future.

More hurricanes in Western Europe
Research conducted by institutes such as the Royal Netherlands Meteorological Institute (KNMI) indicates that climate change in the future may lead to more hurricanes in Western Europe and that they may have a greater impact.

The effects are highly dependent on the path of a hurricane and the strength of the winds. To investigate the effects in the future, Deltares experts ran simulations for other possible hurricane paths.

Different paths
These simulations show that water levels and waves at different locations could be a lot higher, possibly making flooding more likely when a hurricane follows a slightly different path.

Expert Deepak Vatvani of Deltares comments: ‘It will be important in the future to have water models that simulate hurricanes accurately so that we can properly predict the possible effects. At present, we do not take hurricane-force winds into account adequately and so we may be underestimating the impact.’

Ireland and Great Britain in the firing line
The simulated hurricane paths suggest that more severe flooding is likely in Ireland and Great Britain in particular and that France may also suffer damage in some scenarios.

The Netherlands seems unlikely to be affected by hurricanes on the basis of these simulations but that depends on the path taken by a hurricane.

AIWW 2017: Setting the stage for a circular economy https://www.dutchwatersector.com/news-events/news/28049-aiww-2017-setting-the-stage-for-a-circular-economy.html dws-aiww2017-circular-economy-ng-pub-770px‘We have a huge problem with water and the circular economy is essentially one of the few possible solutions’ says Tomás Michel, president of the Brussels-based Water Supply and Sanitation Technology Platform (Wsstp) on the eve of the Amsterdam International Water Week (AIWW) 2017. ‘The circular economy cannot be implemented by single actors. The AIWW provides again an opportunity for different stakeholders to come together and showcase and discuss the concept', he adds.

Next to Michel, several other top experts will be present at the AIWW to bring the issue of resource recovery in the water sector a step further.

Circular economy, together with resilient cities, will be a major topic at the Amsterdam International Water Week that will take place from 30 October till 3 November.

dws-aiww2017-circular-economy-michel-350px President Tomás Michel of Water Supply and Sanitation Technology Platform (Wsstp) will be leading the AIWW-session on Next Tech Ventures and Upscaling on Wednesday 1 November.

New mind set
‘The concept of circular economy definitely includes a need to reuse water, but goes well beyond this’, continues Michel. ‘It demands a complete change of mindset on how we consume, produce, grow food’.

Michel will be leading a session on 'Next Tech Ventures and Upscaling' on Wednesday 1 November. The aim for the workshop is to identify success factors that allow use of a technology to be replicated in different locations, including ensuring the right skills are developed through capacity building.

‘It’s important that, for innovation to happen, there is this environment of collaboration, partnership and capacity building. I think what we can achieve at AIWW with this workshop is precisely to take one more little, but important, step forward in that direction,’ says Michel.

Zero waste nation
Also present at the AIWW, will be Chief executive Peter Joo Hee Ng (on top photo) of PUB Singapore. He will participate in Global Dialogue of the Utilities Leader Forum. Peter Joo Hee Ng will share the latest experiences on large scale water re-use and the recent introduction of sustainable energy at Pub’s major water plants.

He will reflect on Singapore’s wider efforts to achieve a circular economy. ‘We recognise that there will be continued challenges for the future in terms of increasing competition for resources,’ says Peter. ‘We will work towards a Zero Waste Nation by reducing our consumption, as well as reusing and recycling all materials to give them a second lease of life,’ he adds, pointing also to plans to create ‘Living Labs’ to test-bed ideas.

dws-aiww2017-circualr-economy-verstraete-350px Professor Willy Verstraete will deliver a key note at the workshop Water Cycle Recovery and Reuse Implementation on Wednesday 1 November.

New steps ahead
Belgian top expert on anaerobic waste treatment, professor Willy Verstraete will deliver a key note at the workshop 'Water Cycle Recovery and Reuse Implementation' on Wednesday 1 November.

Verstraete emphasises the importance for the global water community to take new steps ahead. Politicians and public are ready for a cyclic economy, he is convinced.

‘Climate change will result in a more variable supply of water and this is a key issue in the context of the water cycle. This must be our first focus', says Verstrate on the occasion of the AIWW.


Visitors of the Aquatech trade fair can walk through a 'sewer tube' to see many different products that can already be recovered from municipal waste water.

Exhibition of new technologies
The AIWW conference will coincide with the water technology trade fair Aquatech Amsterdam where the latest technology on water resource recovery will be shown.

At the entrance of the trade fair, in the Europe Foyer, there will be a special circular economy expo in a walk-through ‘sewer’ tube. It will show the latest’s development in the recovery of water, energy and materials from municipal waste water.

Another highlight on the theme of circular economy is the CirTec-technology (in hall 7, 07.450) to recover toilet paper from waste water and process it into cellulose. In the Netherlands the first such recovered cellulose has been used in asphalt for a bike lane.
