Dutch Water Sector http://www.dutchwatersector.com Dutch Water Sector Feed World Water Day 2017: Why waste water? http://www.dutchwatersector.com/news-events/news/24268-world-water-day-2017-why-waste-water.html dws-wwd2017-poster6-770pxToday we celebrate World Water Day and this year the focus is on wastewater and ways to reduce and reuse as over 80 percent of all the wastewater from our homes, cities, industry and agriculture flows back to nature untreated, polluting the environment and losing valuable nutrients and other recoverable materials.

So let's reduce the quantity and pollution of our wastewater, and safely reuse as much as we can.

Don’t be a waster. Reduce and reuse wastewater.

Halving discharge untreated waste water
For all these reasons, the global community has committed to achieving universal and equitable access to safe and affordable drinking water by 2030, as part of the United Nations' Sustainable Development Goals (SDGs). A key target of SDG 6.3 is to improve water quality by reducing pollution, halving the proportion of untreated wastewater and substantially increasing recycling globally.

In fact, wastewater is a source for water, energy and nutrients. For example, farmers are increasingly interested in recycling wastewater as both a source of irrigation and recycled nutrients.

Effective wastewater management not only improves lives and the environment, but also makes economic sense, creating new business opportunities and long-lasting, sustainable jobs.

BAM Nuttall to construct deep water quay in Poole harbour, UK http://www.dutchwatersector.com/news-events/news/24250-bam-nuttall-to-construct-deep-water-quay-in-poole-harbour-uk.html dws-bam-nuttall-poole-harbour-aerial-725px
Poole Harbour Commissioners (PHC) has appointed civil engineering company BAM Nuttall as the main contractor for a 10 million UK pound project to provide the commercial port of Poole with a new 200m long deep water quay. The new quay is scheduled to be ready by January 2018.

Reuse of dredging material
Approximately 1,800 tons of steel piles will be needed to construct the new quay, all of which will be delivered by sea. In addition, the majority of the material reclamation fill is to be taken directly from the port’s maintenance dredging scheme.

This approach removes the need for road deliveries and uses a ‘waste’ product in the new construction. And, in order to ensure that local companies benefit from this project, all marine plant has been sourced from suppliers in Poole and Southampton.

Expanding cruise market
“This is an important step forward in the expansion of the port,” said Jim Stewart, PHC’s Chief Executive. “It means we will be able to accommodate vessels up to 220 metres long in a variety of different sectors including yacht transportation, bulk cargo, short sea containers and project cargo. As a result, we expect to see up to a 50 percent increase in tonnage in cargo across the quays.

“It will also allow us to take advantage of the rapidly expanding cruise market. At present we can only take smaller cruise ships but, with these new facilities, we will be able to accept visiting cruise ships accommodating over 1000 passengers”, he added.

Richard Hayman, Contracts Manager at BAM Nuttall commented: “We are delighted to have secured this prestigious contract and to have the opportunity to continue our long and successful history of working in the port.”

Construction of West 8’s design Xinhua Waterfront Park kicks off in Shanghai, China http://www.dutchwatersector.com/news-events/news/24189-construction-of-west-8-s-design-xinhua-waterfront-park-kicks-off-in-shanghai-china.html dws-west8-xinhua-park-binjiang-avn-770pxThe construction of the 1.6 km Xinhua Waterfront Park at the east coast of Huangpu River, Shanghai, China, will start at the end of this month.

The waterfront has been designed by Rotterdam-based West 8 architects, in cooperation with Tongji University.

Waterfront with vitality
According to the Shanghai Municipal Government that commissioned the project, it is their aspiration ‘to create a waterfront with vitality’. Their key to the design of the park is to ‘promote public health and to enrich citizen’s welfare’.

Given these objectives, West 8 designed a world-class waterfront park that harmonizes vegetation, atmosphere, culture and art against the metropolitan backdrop of Shanghai City.

dws-west8-xinhua-waterfront-impression-350px Impression of the new Xinhua Waterfront Park, along the banks of the Huangpu river.

Public green space
West 8's design for Xinhua Waterfront Park will turn the east coast of Huangpu River to an integrated waterfront corridor with new city squares and waterfront public green space, complete with cycling tracks connecting to the city center.

This project has been announced by the Shanghai Municipal Government as one of the key projects of the Waterfront green space infrastructure framework, and was included in the recent ‘13th Five-Year Plan’ issued by the Chinese National Development and Reform Commission as a pioneer project.

Four new squares
West 8's approach is 'simple yet beautiful, relaxed and romantic' and introduces four new major city squares:
● Minsheng square with a ferry terminal area
● Harbour square with a historic industrial architecture
● Baizi square with a retaining wall
● Xinhua square, functioning as a key node

River basin management of Volta delta focusses on balancing preservation and development http://www.dutchwatersector.com/news-events/news/24178-river-basin-management-of-volta-delta-focusses-on-balancing-preservation-and-development.html dws-tud-volta-fish-770px
Researchers from the Delft University of Technology and the Delta Alliance joined forces with the Ghanaian Development Institute and the University of Ghana, in Accra to discuss the challenges for integrated planning and sustainable management of the Volta river delta.

At two recent workshops Dutch and Ghanaian experts recognized that the problems in the delta relate a lack of land use planning and a limited enforcement capacity of local authorities. It was concluded that the key challenge is to develop a plan that balances nature conservation and development and that is integrated within the traditional governance structures.

This is reported by urban deltas researcher dr. ir. Peter van Veelen at the Delft University of Technology (TU Delft) in a long read on the website of TU Delft WaterViewer.

dws-tud-volta-delta-map-350px  The Akosombo dam has large impact on the lower delta of the Volta river.

Rich natural environment
Coastal erosion, flow loss on the Volta river due to the Akosombo dam and poor land use planning, are some of the interacting problems the Volta river delta is facing.

According to Van Veelen the river delta is one of the few African deltas that is not yet urbanized and still has a rich and partly intact ecosystem. Its coastal lagoons and creeks serve as good breeding grounds for fish species and for migrating bird species.

The rich lagoon and coastal zone ecosystem is an important source of food and provides firewood for coastal communities. The coastal communities mainly live from traditional fishing, small-scale horticulture and salt mining.

Lack of sediment
The ongoing strong coastal erosion is one of the more urgent issues, writes Van Veelen. Although data is generally incomplete or poor, the coastal erosion is partly attributed to a lack of sediment that is trapped behind the dams in the Volta river. Other contributing circumstances are effects of sea level rise and associated change of coastal currents along the West African coastline.

Another serious problem is the illegal sand winning, driven by the city expansions of Accra and Tema. The illegal sand mining causes further coastal erosion of the beach and the natural flood protection.

dws-tud-volta-delta-erosiom-keta-350px Coastal erosion in the village of Keta.

Stabilization versus access
On average, the rate of loss of land is estimated to a range between a 1- 2 m a year. Already, some coastal villages and infrastructure are lost to the ocean.

Engineering solutions such as the construction of groins and revetments stabilized parts of the coast but block access to the coast, affecting traditional marine fishing activities. The construction led to increased coastal erosion elsewhere along the coast.

Joint research agenda
At two well-attended meetings in Ghana experts recently exchanged ideas, and discussed a joint research agenda between Ghanaian and Dutch universities.

The discussions with the stakeholders revealed that development and integration of base line data, for example on coastal erosion, salinization and urbanization, are key to start understanding the complex relations that define sustainability of the delta system.

According to Van Veelen a key challenge is to develop a plan in which both conservancy and development are balanced and that is integrated within the traditional governance structures.

Most remarkable polling station for Dutch elections on brand new nature island http://www.dutchwatersector.com/news-events/news/24147-most-remarkable-polling-station-for-dutch-elections-on-brand-new-nature-island.html dws-markerwadden-voters-770px-1Probably the most remarkable polling station for the elections of a new Dutch parliament was on the nature island Marker Wadden. The construction of the island was completed only last year and officially it is still closed to the public. However, on the occasion of the Dutch elections a ferry boat took people to the island where they could vote for the candidate of their choice.

dws-markerwadden-warning-sign-350px A remarkable combination of signs. Red sign: pointing in the direction of the polling station. Yellow sign: warning for quick sand.

Beautiful spring weather
More than 1,300 voters took the opportunity to queue up for the ferry boat and the polling station on the remote and sandy island. No doubt the beautiful spring weather encouraged them to take the boat and combine the voting with a visit to the latest showpiece of Dutch civil engineering.

The ferry boat took an hour. Voting and wander around the island, took most visitors half a day.

The first voters to be brought in, were the local officials. A group of young people who voted for the first time took a rib speed boat.

The island Marker Wadden is an example of eco-engineering, in the Netherlands known as Building with Nature. Contractor Boskalis only constructed some beaches, sand banks and low dunes, linked by a rock dam.

These constructions have been shaped in such a way that fine sediment settles in shallow areas and creeks, thus creating natural wetlands.

dws-markerwadden-opening-350px Construction of the first island was completed in September last year. Because of its special shape the construction will trap fine sediment and gradually turn into a wetland of marshes and mud plains.

Poor water quality
The island is situated in Lake IJssel, the largest fresh water basin in Europe. In contrast to other large, shallow European lakes, the lake has a poorly developed littoral zone due to its non-natural origin and due to the continuous mixing and high turbidity.

The turbidity hampers light penetration through water and the overall ecological development.

Archipelago of five islands
Dutch Society for the Preservation of Nature (Natuurmonumenten), together with the national department of public works Rijkswaterstaat and a consortium (Boskalis, Royal Haskoning DHV, Deltares and Alterra) committed themselves to bringing life back to the lake.

By removing the mud layer from the lake’s bed and re-using the soft sediment to build wetlands, they are expecting to transform a part of the lake into the new nature reserve Marker Wadden.

The goal is to create an archipelago of five islands by 2020, covering 1000 ha of land, marshes and mud plains.

Recently the construction started on the other four islands.

Buwatec introduces new assortment of stronger and special coated water storage tanks http://www.dutchwatersector.com/news-events/news/24114-buwatec-introduces-new-assortment-of-stronger-and-special-coated-water-storage-tanks.html dws-buwatec-industrial-770px-Buwatec announced the launch of a new assortment WSW water storage tanks in three qualities pre-fabricated, easy-to-handle versions. The new versions include the use of stronger steel quality and a special double sided thermoplast coating. The new versions will become available in April.

Specific task
The new product differentiation allows Buwatec to consider the specific use of a tank and offer an economy, standard or industrial tank version. This can result in the use of less steel.

All new versions of the modular steel water tanks will be supplied with a new standard patron for bolt sets. This requires less bolts in high tank sizes.

The thermoplast coating Plastisol, makes the tank corrosion and maintenance free for 25 upto 30 years.

Coverage to keep water cool
One of the users of a Buwatec water stoage tank is US farmer Bogdan Caceu. He searched the world to solve an irrigation problem on his farm. In the end he build his own water storage system with a pre-fabricated Buwatec tank.

As cover he used BUHexa-covers to keep the water cool, algae-free and reduces evaporation to a minimum.

This way he put together a simple, inexpensive water storage system that holds 35,000 gallons.

“It doesn’t get us through the entire season, but I wanted to see how inexpensive and easy to build it could be,” Caceu said.

Caceu estimated that the entire system cost less than 16,000 US dollar.

The call for proposals was collaboratively launched to contribute to the United Nation’s Sustainable Development Goals (SDGs) in an innovative way and with a focus on the most vulnerable people in low- and middle-income countries. A total budget of 7 million euros is available.

dws-nwo-sdg-researhc-map-350px  Low- and middle-income countries in the world (source: WEF)

Tangible outputs, global perspectives
Because of the complexity of the challenges, an interdisciplinary and transdisciplinary approach of co-creation is needed to be able to contribute to the SDGs.

Furthermore, research projects should generate tangible outputs -other than knowledge- that are accessible, affordable and applicable for practitioners in low- and middle-income countries (LMICs).

Collaboration with scientists from LMICs clears the path to innovative insights and breakthroughs that would otherwise be beyond the reach of Dutch science.

This joint initiative contributes to more coherent research funding and to a collaborative effort of the Dutch science community in addressing global challenges.

Dutch and local researchers
Research proposals should include close cooperation between Dutch and local researchers, between different disciplines and between knowledge institutes, governments, NGOs, private partners, or other relevant end-users.

The co-funding research organisations are: Delft University of Technology, Erasmus University Rotterdam, Unesco-IHE Institute for water education, University of Amsterdam, Utrecht University, VU Amsterdam and Wageningen University & Research.

The deadline to submit a proposal - only after preselection and approval of the co-funding research organisation - is 23 May 2017. Click here for more detailed information on the call ‘Tackling Global Challenges through Use-Inspired Research'.

Patrick Moriarty gives TED talk on building water systems that deliver 24/7 http://www.dutchwatersector.com/news-events/news/24051-patrick-moriarty-gives-ted-talk-on-building-water-systems-that-deliver-24-7.html dws-irc-tedx-moriarty-open-eyes-770px“Let’s face it. It is when the water doesn’t get out of the tap, we begin to notice the system”, noted Patrick Moriarty of knowledge centre IRC on water and sanitation services. Holding his first TED talk he addressed the general blindness for water systems and tendency to see only what they deliver. Moriarty urged to focus more on the whole water supply in developing countries. “The only way we are going to end the need for development aid, is by building a system."

IRC CEO Patrick Moriarty held his first TED talk at TEDxDenHelder on 13 February.

dws-irctedx-moriarty-portret-350px  IRC CEO Patrick Moriarty: "It's about the systems". 

System blindness
"We live in a world surrounded by complex systems that deliver health, education and water, sanitation and hygiene to us”, Moriarty explained. “Despite this we are largely blind to them. In both the rich and developing world this ‘system blindness’ is responsible for failed investments and poor services on a huge scale.”

“What can we learn from people who are building systems in developing countries? What are the long term costs of quick wins?", he asked himself.

Lack of appreciation
Patrick Moriarty is an engineer with more than 20 years of experience building sanitation systems in South Asia and Africa. He has been with IRC since 2000. In his TED talk he referred to his work in Ghana where he worked on a nationwide project to create ‘a healthy water system that can repair itself’ as he mentioned it.

The system blindness leads to a lack of appreciation of the system that delivers the water, said Moriarty. “It means that now up to today 30 percent of the installed water infrastructure in rural Africa is not working at any time. Billion dollars of aid, flushed down the drain.

Systems within systems
Moriarty talked about systems within systems. “Systems that rely on people, on money, on infrastructure and on information, to make them work. Here the crazy thing comes in. For a water system to work, for water to come out of the tap, or things to happen when you flush the toilet, the whole system has to work, all the time”.

When the system fails, there has to be an ability to repair it, he went on. “Pipes break down, taps stop working. Shit gets into the environment, kids get sick and die. But because we are system blind, we make stupid decisions.”

dws-irc-tedx-moriarity-system-scheme-350px The whole system of sanitation.

Quality of services
“We vote for people who say they are going to reduce tax and improve the quality of services. We give money to charities who want to use it to build new infrastructure. But when that infrastructure fails they are nowhere to be seen”, he warned.

Moriarty shared his four years of experience in Ghana, not building a single pump or a single meter of pipe. “We took away the system blindness. We made them aware why so many water systems were failing and made them decide to do something about that”.

“We planned, we budgeted”, he continued. “Not just for new hardware, but also to fix the stuff that was already there. We brought back water services to thousands of people.”

Go-ahead for expansion of Dutch Marker Wadden archipelago with four new islands http://www.dutchwatersector.com/news-events/news/24034-go-ahead-for-expansion-of-dutch-marker-wadden-archipelago-with-four-new-islands.html dws-rws-marker-wadden-aerial-first-island-770px-1Contractor Boskalis started the construction of four new islands of the Marker Wadden archipelago, the Netherlands, on 8 March.

The islands are constructed on behalf of nature conservation organisation Natuurmonumenten and national department of public works Rijkswaterstaat, and are expected to be ready by 2018.

The ceremony to mark the official start of the expansion took place on the first island that was completed in September last year.

dws-rws-marker-wadden-tweel-schultz-dronkers-350px  The expansion was officially marked by Dutch minister Melanie Schultz van Haegen (middle) who revealed a large impression of the archipelago as it will look like by 2020. (photo: Marten van Dijl)

Public-private partnership
The construction of the four new islands in the shallow IJssel lake, one of the largest fresh water lakes in Europe, is financed by public and private organisations. Together they raised 38 million euro for this new phase of the development of the archipelago.

By 2020 the whole archipelago is expected to be ready, covering 1000 ha of land, marshes and mud plains.

Natural sedimentation
The construction is a show case of the concept of Building with Nature. Boskalis will only construct some dams. These dams are placed in such a way it traps sediment.

As the silt sediment accumulates, the predesignated areas will be filled slowly, creating land, marsches and mud plates.

First island
Last year Boskalis completed the construction of the first 250 ha island (see top photo). The work was limited to the construction of a rock dam to protect the island from storms and some silt dams and beaches.

These dams will trap the silt sediment of the lake that is essentially too soft for building an island.

Water quality
The archipelago will form a unique ecosystem that will boost the biodiversity and increase the water quality of the lake.

Moreover, the lake will become more attractive for water sports and nature lovers. The nature islands of the Marker Wadden will be accessible to the public.

Circular economy can almost fully undo water stress in California http://www.dutchwatersector.com/news-events/news/24002-circular-economy-can-almost-fully-undo-water-stress-in-california.html dws-ing-deltares-circular-poster2-770px
If Californian water users close the water loop and make their water systems regenerative, 12 billion cubic meter of water can be saved annually. This would reduce the water stress in this US state by more than 90 percent.

This emerges from the Dutch retail bank ING report Less is more: Circular solutions to water shortages, for which the research institute Deltares supplied the datasets.

The report focuses on the effects of a circular economy on the water stress in six regions around the world. Potentially these regions can save 400 billion cubic meter of water yearly, equivalent to 11 percent of global water demand and almost the entire water consumption in the US.

dws-ing-deltares-circular-graphic-350px    Source: ING calculations based on Deltares modelling

Reduction of water stress
The water savings by the introduction of multiple cycles cannot fully compensate for the expected water shortages, the study concludes.

Up to 2050 California is expected to experience water shortages in 30 out of the 34 years. According to the studies, the circular economy has the potential to reduce this considerably to 13 years.

The report shows that more circular water systems can improve the local balance of water supply and demand in all six regions (Northern India, California, Ghana, United Arab Emirates, Bangladesh and the Netherlands).

New business opportunities
Gerben Hieminga, ING Economics Department: “Applying the principals of the circular economy requires transformative change of current linear water systems, which in turn also presents businesses with a range of opportunities throughout the supply chain.”

“Nonetheless, we must be aware of the fact that these measures cannot be implemented in isolation,” says Hieminga. “Barriers to progress, such as costs of implementation, regulatory control and free water rights, as well as the entire water cycle from supply, demand and behaviour, needs to be improved before a circular water solution can be as effective in achieving such positive results.”

dws-ing-deltares-circular-graphic2-350px If no changes are made, global water demand is forecasted to outpace the sustainable water supply in 2040 by 35% (source: ING – Too Little Too Much, 2015, based on IFPRI and Aquastat)

Global water model
Deltares looked at how measures based on the circular economy can impact the efficient use and recycling of water in agriculture, industry and households.

The global water model Water2Invest was used to calculate the potential effect of these measures on water scarcity in six countries.

This model was developed by Deltares in collaboration with, among others, consultancy firm Future Water and Utrecht University.

To calculate the potential of a circular economy in California, the following water measures were identified:
• maintain water quality in ground water resources.
• behavioural change and water efficient technologies introduced by industries and households.
• apply water efficient irrigation techniques and increase the use of water efficient crops as well as drought tolerant crops.
• water retention through aquifer storage and rain water harvesting coupled with water transfer possibilities between storage facilities.
• re-use of grey water by businesses and households

Visit to the Netherlands
The signing follows a visit of a Japanese delegation to the Netherlands in November last year. The Japanese experts attended the fourth International OTEC conference and visited some of the innovative Dutch marine energy companies and test facilities, such as Tocardo, Fishflow Innovations, REDstack and the Tidal Testing Centre at the closure dam Afsluitdijk.

About Ocean thermal energy conversion
Ocean Thermal Energy Conversion (OTEC) is a marine renewable energy technology that generates electricity by exchanging heat with the warm water from the ocean surface and with the cold water from the deep ocean.

The exchanged heat drives a Rankine Cycle, which converts it to electricity. The technology is viable primarily in equatorial areas where the year-round temperature differential is at least 20 degrees Celsius.

dws-tudelft-otec-bluerise-scheme-350px  OTEC generates electricity by exchanging heat with the warm water from the ocean surface and with the cold water from the deep ocean.

About Bluerise
In cooperation with the Delft university of technology, the Dutch start-up company Bluerise designed and constructed a room size demonstration of an advanced OTEC power plant.

The small-scale working power-extraction cycle is a ‘proof-of-principle’ and a real innovation, since it will be the first mini OTEC plant demonstrating the chosen advanced cycle.

About Ocean Energy Platform of Delft University of Technology
Ocean Energy Platform stimulates research and education in ocean energy application at Delft University of Technology.

The platform develops a joint research agenda, actively pursues funding opportunities, stimulates internal knowledge exchange, and takes care of external communication about ocean energy.

Workshop on unlocking rainwater harvesting practises in Bangladesh http://www.dutchwatersector.com/news-events/news/23893-workshop-on-unlocking-rainwater-harvesting-practises-in-bangladesh.html dws-rain-workshop-bangladesh-improvements-770pxDutch-based non-governmental organization RAIN, in cooperation with Bangladesh University of Engineering and Technology (ITN-BUET), facilitated an expert consultation workshop in Dhaka in January.

In the workshop the results of the research on the potential of rain water harvesting practises were discussed.

This workshop was scheduled after completing a desk study and field visits in the coastal regions of Bangladesh.

dws-rain-bangladesh-improvements-rice-field-350pxToo much, too little
In Bangladesh coastal region rainfall in the monsoon season is abundant, but almost absent during the dry season, leading to water scarcity for households and farmers.

Due to high salinity in surface and groundwater and natural arsenic pollution, people in the coastal region of Bangladesh, are facing water crisis in many areas and are looking for alternatives.

Benefits of 3R practices
Rain water harvesting practices, such as 3R (recharge, retention and reuse) are often thought as a potential solution to enhance the availability of water.

RAIN, with funding of the WASH Alliance International, initiated an in-country study to understand the context of current water supply in the coastal region, to identify main challenges in implementation of the 3R practices, the benefits of such practices and the potential for scaling up of successful practises.

The workshop was participated by partners of WASH Alliance International as well as other organizations implementing WASH in coastal areas.

Academicians, researchers and experts having experience of working on RWH practises in the coastal region also attended the workshop and shared their feedback on the research findings.

In a presentation existing local 3R practices and the results of a FIETS sustainability assessment of these practises were shared. The recommendations of the participants will be addressed in the final version of the research report.


About Rain and 3R
RAIN has extensive experience in programme and project management in the field of rainwater harvesting, collection and buffering. With local and international partners it has implemented rainwater programmes and projects in various countries in East and West Africa and Southeast Asia.

RAIN actively promotes the 3R (recharge, retention and reuse) and MUS (Multiple Use Services) approaches in which rainwater harvesting and collection plays a key role.

3R is an initiative of four Dutch entities (RAIN, Acacia Water, MetaMeta and Aqua for all). The concept is about cheap, decentralized storing of water in the soil profile that, when applied at scale, it does not disrupt the local environment. The measures contribute to diminish the risk of crop failures in rain-fed agriculture.

About Dutch Wash Alliance and FIETS
Six Dutch NGO's work together in the Dutch Wash Alliance with dozens of local partners in eight low-income countries in Africa and Asia, to build and to strengthen an environment in which local people can assert and realise their right to sufficient quantities of safe drinking water, adequate sanitation and hygienic living conditions, in order to improve their health, nutritional status and economic living standard.

The programme is funded by the Netherlands Ministry of Foreign affairs, started in 2011.

The alliance follows the FIETS strategy, pursuing Financial, Institutional, Environmental, Technical and Social sustainability.

Deep Water Energy to install Oryon Watermill on Suriname river http://www.dutchwatersector.com/news-events/news/23876-deep-water-energy-to-install-oryon-watermill-on-suriname-river.html dws-deepwater-oryon-water-mill-ulft-770pxDeep Water Energy is about to install its first underwater hydropower Oryon Watermill on the Suriname River, near the village of Duwatra. The 30 kW off-grid power station will generate enough electricity to support the inhabitants of a total of three villages.

Installation is planned for July this year and, once fully operational, it will be passed on to the local population to replace the current polluting diesel generators.

dws-deepwater-oryon-suriname-river-350px The selected location on the Suriname river.

Suitable location
DWE’s international sales manager Dolf Pasman and business partner Jaap Ory started talks on the project with the responsible Suriname government departments in January 2012.

The talks led to the choice of an off-grid location and recently the Netherlands Enterprise Agency (RVO) decided to support the project financially.

Increase of electrical output
The Oryon Watermill is an underwater construction consisting of a housing that directs the flow of the river water to a turbine.

The water pushes the turnable blades on one of the three wings that are connected to a vertical axis.

A special funnel shaped housing can accelerate the river water up to 80 percent, increasing the electrical output.

dws-deepwater-oryon-water-mill-2- Lowering of the Oryon Watermill at the demonstration location at Ulft, the Netherlands in 2014.

DWE placed its first Oryon Watermill in the forced water of a weir at Ulft, the Netherlands, in 2014. Here the fish-friendliness and the actual power generation were tested.

This installation also served as demonstration location for interested parties to observe the performance of the watermill. The location has been visited by delegations from the Philippines and Suriname.

Growing interest
Dolf Pasman and Jaap Ory see a growing interest for their watermill all over the world: “We receive new requests for information and quotations almost on a daily basis.”

They realise these requests will not lead into orders straight away. “We are talking about long and complicated processes. But this year we expect first substantial orders”, said Pasman and Ory.

Youth ambassador Amsterdam International Water Week keen to attract more young water professionals http://www.dutchwatersector.com/news-events/news/23849-youth-ambassador-amsterdam-international-water-week-keen-to-attract-more-young-water-professionals.html dws-aiww-young-professionals-stand-770pxjpg-1“We are really very keen to get many young professionals at the Amsterdam International Water Week”, says Andrea Kralikova, the current Youth Ambassador of Amsterdam International Water Week (AIWW).

Kralikova, who works for international consultancy Accenture, took up her Youth ambassador role in 2015 during the last AIWW. She is now heavily involved in the planning for the forthcoming edition in November, helping to ensure there is a strong representation of youth interests.

dws-aiww-ambassador-sagen-kralikova-350px Andrea Kralikova (right) takes over the role of Youth Ambassador from Marie Rødsten Sagen during the 2015-edition of AIWW.

Strong youth interest
As Youth Ambassador Kralikova´s main role is to ensure there is a strong representation of youth interests in the programme of the Amsterdam International Water Week.

The AIWW will be held for the fourth time from 30 October to 3 November 2017. The event includes the AquaTech Amsterdam trade exhibition on watertechnology, the Floodex Europe exhibition on flood control and the three day AIWW conference on the transition to a circular and resilient water environment in urban areas.

Passionate about water
Certainly some exciting new features are emerging from her role to represent the youth programme team set to achieve a step up from the successes of 2015. “The difference for the youth programme this year is we don’t only want to focus on students”, she says, adding. “We are really very keen to get many young professionals there.”

The interaction is an experience that she has found extremely valuable. “It has certainly been rewarding for me – not only an opportunity to meet lovely people passionate about water, but also it was a learning process for me,’ she says. ‘It’s really been broadening my horizons.”

dws-aiww-youth-ambassador-winning-pitch-350px Some 200 young water professionals participated in the 2015-edition of AIWW and on the final day they ended up in a very vivid pitch battle. The winning team pitched the idea of a smart card for women in slums to have access to a public toilet.

Search for her replacement
With planning escalating towards the event in November, Kralikova still has much to do to continue contributing to the expanded youth programme.

A new ambassador will be appointed in November, but the search for the replacement will begin soon. She is keen to encourage potential successors to put themselves forward.

“I think for anyone who is really passionate about water and is at the beginning of their professional career in the water sector, this is a really great opportunity”, says Kralikova.

About Young AIWW
The upcoming edition of the Amsterdam International Water Week (AIWW) includes an extensive program for students and young professionals, organized by and for young water professionals. The programme includes participation in various conferences, workshops, events and challenges.

Royal IHC to build world’s largest cutter suction dredger for Belgian dredger DEME http://www.dutchwatersector.com/news-events/news/23831-royal-ihc-to-build-world-s-largest-cutter-suction-dredger-for-belgian-dredger-deme.html dws-ihc-impression-spartacus-770px-1Royal IHC has been awarded a contract for the design, construction and delivery of a self-propelled cutter suction dredger for Belgian dredging company DEME.

The newly built CSD, called Spartacus, will be 164 metres long. With an installed engine power of 44,180 kW it will be the largest cutter suction dredger in the world.

The Spartacus will also be the world’s first LNG-powered CSD and follows the order of the first LNG-powered Trailing Suction Hopper Dredgers (TSHD) ‘Minerva’ and ‘Scheldt River’.

dws-ihc-spartacus-launch-tshd-scheldt-350px DEME’s dual fuel trailing suction hopper dredger (TSHD), Scheldt river, during the launch ceremony last January at Royal IHC's shipyard in Krimpen aan den IJssel, the Netherlands.

Dual-fuel technology
According to the specification released by Royal IHC its four main diesel engines can run on LNG, MDO and HFO, and the two auxiliary engines have dual-fuel technology.

The application of LNG to power TSHDs has proven to be a very complex puzzle for the Dutch ship builder.

In close cooperation with DEME, Royal IHC and Vuyk Engineering Rotterdam have managed to fit all the pieces together.

One-man operation
Other innovations on board will include a waste heat recovery system that converts heat from the exhaust gasses to electrical energy.

The dredge control is arranged for a one-man operation. The vessel will have a heavy-duty cutter ladder and can reach a dredging depth of 45 m.

dws-ihc-spartacus-launch-tshd-jun-yang1-350px Last year Royal IHC completed the delivery of the world largest trailing suction hopper dredger (TSHD), Jun Yang for the Chinese dredging firm CCCC Guangzhou Dredging Co.

Benchmark for dredging industry
“We can state that this CSD is the largest and most complex that IHC has ever built,” said IHC's CEO Dave Vander Heyde. He thanked DEME for giving his company the opportunity to build the world’s first LNG-powered cutter suction dredger.

Vander Heyde: “The combination of power, size and innovations makes it a true challenge to build. We are proud and honoured that DEME has again placed their trust in us.”

DEME’s Head of Construction and Conversion, Jan Gabriel, emphasized the commitment to green initiatives. “This cutter suction dredger is going to be an important benchmark for the industry and a huge step toward limiting the environmental impact of our vessels”.

The government of Sierra Leone launched a data portal on water and sanitation. The portal displays data analysis features, maps and raw data from the 28,000 water points mapped in 2016.

The open website is a joint initiative led by Sierra Leone’s Ministry of Water Resources and has been set up using open source technologies provided by Akvo.

dws-akvo-wash-portal-sierra-leones-map-350px  All 28,000 water points mapped in Sierra Leone.

Sharing data on water
The aim of the data portal is to publish data for the WASH indicators as established by the Sustainable Development Goal (SDG) number 6 on water.

Additionally the website aims to simplify the way data is shared so all stakeholders can work more efficiently.

Information available includes: water supply access and functionality, water supply and sanitation facilities for households (including newly completed wwtp Kenema on top photo), current sanitation and latrine coverage, and data on demand for latrine emptying services.

Baseline monitoring
The idea is that all progress on water and sanitation facilities in Sierra Leone will be measured, compared and published on this portal over the next 13 years.

This way, the baseline and subsequent monitoring data will provide an important foundation for water sector planning and strategy development of the WASH sector in Sierra Leone.

dws-akvo-sierra-leone-engineers-350px Local water engineers are trained to familiarize themselves with the open access data tools provided by Akvo.

Field surveys
The platform uses the latest open source technology developed by Akvo, a not-for-profit foundation specialized in open source software.

One of Akvo’s latest products is Akvo Lumen. It lets people process the data of field surveys even if they are not data specialists, and produces graphical displays on a dashboard

Akvo developed a multi-language tool for collecting, evaluating and displaying any quantity of geographically referenced field data - using smartphones and an online dashboard.

Akvo’s tools are used worldwide to monitor and evaluate improvements to infrastructure and services, and make informed investment decisions based on accurate, current data.

Indymo deploys under water drones to inspect water quality around Surabaya, Indonesia http://www.dutchwatersector.com/news-events/news/23754-indymo-deploys-under-water-drones-to-inspect-water-quality-around-surabaya-indonesia.html dws-indymo-indonesia-drone-turbulent-water-770pxUnder water drones of the Dutch start-up Indymo were recently used to inspect the poor quality of the surface water around Surabaya, Indonesia.

The use of the drones is part of a large-scale international research project to find ways to improve the water quality of the Brantas- and Surabaya rivers that both end up in this Indonesian city.

The research is conducted by a Dutch-Indonesian consortium with experts from many organisations, including the Indonesian organisation Ecological observation and wetlands conservation (Ecoton), the Indonesian water board Jasa Tirta 1, the river basin management organisation BBWS and the technical university of ITS Surabaya.

dws-indymo-indonesia-water-pollution-350px  The heavily polluted rivers in and around Surabaya, Indonesia.

Healthy rivers
The consortium was hosted by the non-governmental organisation Ecological observation and wetlands conservation (Ecoton) that launched a number of initiatives to stop the pollution of these rivers and make them healthy again.

The activities range from raising awareness amongst citizens, to organizing lawsuits against polluters, and placing warning flags on locations where the river water is dangerously contaminated.

Base-line assessment
Together with Ecoton, Dutch-Indonesian experts started a base-line assessment of all aspects of water quality management, including data collection, modelling, regulation, monitoring and planning. This baseline is a first step to be able to determine the ambition and strategy with the various stakeholders.

To determine the full extent of the pollution of both rivers, different measurement methods have been applied, including the use of underwater drones of the Dutch firm Indymo.

dws-indymo-indonesia-instructions-350pxRandom samples
The current measurement of the water quality, is often random and static with sensors only in one place. An important lesson of the collaborative research is that such random samples are not representative of a body of water, given the water quality parameters in space and time can vary widely.

The use of drones allowed to take a closer look at the 35 m deep sediment underneath a floating fish pond. It was assumed that such fish ponds, by the excessive use of fish feed, are responsible for high nutrient and low oxygen levels.

The measurements showed that the water quality at these ponds do not differ much from other locations. However, there are now clear indications that the sediment is contaminated by accumulation of contaminants which needs further research.

High pollution levels
Measurements with sensors on fishing boats revealed that the water quality varies from location to location. Locations with high BOD and COD levels could be associated with the various points of discharge of domestic and industrial waste water.

The industrial-related measurements have not yet been published but will be discussed first in a constructive and open dialogue with the industry and individual companies.

The joint outcome of sustainable, cost-effective solutions is one of the most important tasks of the consortium in the coming years.

dws-indymo-indonesia-drones-boogaard-lima-350px Floris Boogaard (right) and Rui Lama (left) holding the equipment they used to measure the water quality.

About Indymo
Indymo is a start-up that works in the field of the management of water resources and water quality.

The company focusses on innovative ways of monitoring water quality and ecology using underwater drones and apps.

Indymo has two offices in Leeuwarden and Delft and the main supporting partners in this project are Delft university of technology, consultancy firm Tauw, water quality centre WLN, research institute Deltares and specialist on floating urbanization DeltaSync.

Room for the River programme nears completion with new by-pass on IJssel river, the Netherlands http://www.dutchwatersector.com/news-events/news/23707-room-for-the-river-programme-nears-completion-with-new-by-pass-on-ijssel-river-the-netherlands.html dws-rftr-veesen-intake2-770pxAfter five years of construction a new 8 km long flood channel by-passing the Dutch river IJssel was officially commissioned by Dutch minister Melanie Schultz-van Haegen and chairman Tanja Klip-Martin of Vallei and Veluwe Regional Water Authority on 23 February.

The new by-pass is one of the last in a series of 30 projects of the national flood protection programme Room for the River and is designed - in case of extreme discharges - to lower the level of the river IJssel by 71 cm.

Unique is the 800 m wide inlet work (on top photo) with 62 adjustable openings. The project ended up costing 190 million euro and was realized by a consortium of two contractors, Boskalis and Van Hattum and Blankevoort.

dws-rftr-veessen-map2-350px  Normal water levels (left), high water levels (middle) and extreme high water levels (right). 

Additional discharge capacity
In case of extreme high water levels the valve of the inlet work will be lifted, allowing the water to enter the by-pass. This will increase the river’s discharge capacity with an additional 1.145 m3/s.

That is 45 percent of the total discharge capacity of the river at that specific location.

For the creation of the by-pass two new parallel levees were constructed with a total length of 8 km.

At the end of the by-pass an outlet work and two pumping stations allow to drain the by-pass after the flood event.

Under normal conditions the by-pass is used by meadowland farmers.

dws-rftr-veesen-opening-schultz-klip-350px Commissioning ceremony with minister Schultz van Haegen (middle).

National flood safety
Some six farmers have moved and nine houses were broken down. Initially the project faced enormous resistance by local residents and farmers.

The responsible water authorities, as well as the contractors, put a lot of effort in communication, trying to explain the necessity of the project and to anticipate on the nuisance from construction works.

In their communication the water authorities emphasized that the additional discharge is part of a national programme to increase the flood safety for 4 million people that live along the main rivers that cross the Netherlands.

On the occasion of the official commission, some residences told the media that they have not been convinced of the necessity for the new flood plain.

About Room for the River programme
Room for the River is a national flood prevention programme, comprising 30 projects mainly along the river Rhine, Netherland's biggest river.

The programme has two objectives. By giving the Rhine river more room its discharge capacity will rise from 15.000 m3/s to 16.000 m3/s. Additionally the projects will improve the spatial quality as well, making the river also economic and environmental more vital.

The Room for the River programme started in 2005 and will cost 2,3 billion euro. The final remaining large project is the widening of the mouth of the IJssel river. This project started in 2015 and is expected to be finished by 2022.

World’s first floating city to be developed in French Polynesia http://www.dutchwatersector.com/news-events/news/23673-world-s-first-floating-city-to-be-developed-in-french-polynesia.html dws-blue21-impression-floating-cities-770pxThe government of French Polynesia signed an historic agreement that allows the development of the first floating city in a lagoon off its most populated island of Tahiti.

The agreement was signed with the Californian Seasteading Institute in January. Dutch company Blue21 is involved in the engineering of the modular floating platforms for such a city in the Pacific Ocean.

Studies into the project should reach completion by 2018 and parties hope to be able to start construction of the world’s first floating city by 2019. The costs for a first pilot are estimated between 10 and 50 million US dollar.

Impacts studies
The deal specifies two points that the project must prove before it gets the green light. Studies will have to prove whether the ambitious plan will benefit the local economy and if it proves to be environmentally friendly.

According to Blue21 this is where the Polynesian plan gets complicated. Originally the non-profit foundation Seasteading opted for the concept of floating cities on the ocean, outside of territorial waters of existing nations. As libertarians they dream of creating self-ruling floating cities.

Smaller platforms
The current Polynesian project, however, foresees in a floating city in a more protected environment. According to Bart Roeffen of Blue21 this implies that the platforms can be much smaller, allowing more space between the platform. “This allows more sunlight to shine in the water of the lagoon, and thus reducing the environmental impact.”

Initially DeltaSync, closely linked to Blue21, did a feasibility study for Seasteading for a floating city in full sea, outside territorial waters. “This means we have to redesign our platforms”, says Roeffen. “Instead of exceptional sized platforms of 50 by 50 meter with wave breakers, we can now think of conventional platforms, in sizes like 20 by 20 or even 10 by 10 meter.”

dws-blue21-impression-floating-pavilion-350px Example of a smaller, more conventional, platform designed by DeltaSync for a pavilion that floats in a former harbour in Rotterdam, the Netherlands, since 2010.

Expert meeting
As an example Roeffen refers to the size of the Floating pavilion in a former harbour in Rotterdam, the Netherlands. DeltaSync engineered the platform for this pavilion that is now in use since 2010.

Roeffen expects that the real engineering can start following a meeting by experts in French Polynesia in March. A more detailed presentation of the whole plan is scheduled for May.

About Seasteading Institute
The Seasteading Institute, founded in April 15, 2008, is an organization formed to facilitate the establishment of autonomous, mobile communities on seaborne platforms operating in international waters.
PayPal cofounder Peter Thiel, invested 500,000 US dollar in the institute and has since spoken out on behalf of its viability.

About DeltaSync and Blue21
DeltaSync is a leading specialist in the field of floating urbanization. It provides consulting and design services and innovative solutions for delta areas.

The company is closely linked to social enterprise Blue21, that wants to inspire cities to expand towards the sea and plug in floating concepts including technologies for the recycling of waste, nutrients and CO2.

Tocardo Tidal Power kicks off demo project at EMEC test site, Orkney, Scotland http://www.dutchwatersector.com/news-events/news/23643-tocardo-tidal-power-kicks-off-demo-project-at-emec-test-site-orkney-scotland.html dws-tocardo-intotidal-orkney-770px-1Dutch-based company Tocardo Tidal Power has entered the tidal scene in the UK with the InToTidal project kick-off and the arrival of Tocardo’s tidal turbine system in Orkney, Scotland

It is the start of Tocardo’s planned 20-year commercial demonstration project at European Marine Energy Centre’s (EMEC) tidal test site Fall of Warness.

The system arrived at Hatston Pier in Kirkwall on 13th February (top photo) where it is prepared for deployment to the EMEC’s grid connected test side.

dws-tocardo-intotidal-flow-test-site-350px  GIS map showing all the flow data, berth positions and bathymetry of the Falls of Warness tidal test site.

Large scale roll-out
With the installation at EMEC’s site, Tocardo is readying for large scale roll-out of its generic solution for tidal energy production. The next installation is foreseen in Canada at the FORCE and Petit Passage locations.

Led by Tocardo, the project brings together Orkney based companies EMEC and Leask Marine, and French research institute IFREMER.

Tocardo has already been working with international shipyard DAMEN, as well as Leask Marine, Bryan J Rendall Electrical and Aquatera in Orkney for the system deployment at EMEC’s tidal site.

Improving tidal power technology
“Our work at EMEC is an important step in de-risking and improving Tocardo’s offshore tidal power technology”, said Hans van Breugel, CEO of Tocardo Tidal Power on the occasion of the arrival in Orkney.

Van Breugel continued: “Our work at EMEC is an important step in de-risking and improving Tocardo’s offshore tidal power technology.

dws-tocardo-array-eastern-scheldt-350px An array of five Tocardo tidal turbines in the Dutch Eastern Scheldt surge barrier that became operational in November 2015.

Increase installed volume
According to the CEO it is Tocardo’s benchmark to produce energy at the cost of offshore wind in the near future. “To be able to achieve this, the tidal energy sector needs to be enabled to increase the installed volume of equipment”, he said.

Van Breugel mentioned the Danish wind energy sector as a good example of industry growth. “A revenue based support mechanism, decreasing over time, has proved to be best in creating a new industry through market incentivisation”.

“Tocardo is ready to become one of the larger inward investment companies into the marine energy sector, with a strong operational and production base in Scotland and Wales. The UK is extremely well positioned as a maritime nation to create new jobs from the growing tidal energy industry.”

About European Marine Energy Centre (EMEC)
Established in 2003, The European Marine Energy Centre (EMEC) is the first and only centre of its kind in the world to provide developers of both wave and tidal energy converters – technologies that generate electricity by harnessing the power of waves and tidal streams – with purpose-built, accredited open-sea testing facilities.

Orkney is an ideal base for these testing facilities as the islands provide an excellent oceanic wave regime, strong tidal currents, grid connection, sheltered harbour facilities and the renewable, maritime and environmental expertise that exists within the local community.

About Tocardo
Tocardo is a Dutch company dedicated to delivering the best and most economical turbines to harvest energy from the world’s oceans and rivers. The Tocardo free-flow in-stream hydro turbines can be compared to ´underwater wind turbines´: free-standing underwater units, generating energy from sea currents and tidal and river flows.

Sarphati Sanitation Awards 2017: First call for outstanding entrepreneurs on sanitation and public health http://www.dutchwatersector.com/news-events/news/23586-sarphati-sanitation-awards-2017-first-call-for-outstanding-entrepreneurs-on-sanitation-and-public-health.html dws-a4a-sarphati-award-2015-van-der-laan-770pxJoin the boost for global sanitation efforts and nominate an individual or organization for the Sarphati Sanitation Awards 2017!

Do you know an individual or organization that contributes to the global sanitation challenge, please nominate them by sending an email to Sarphati2017@aquaforall.org

dws-a4a-sarphati-award-2017-sarphati-350px  Samuel Sarphati was a doctor in Amsterdam and because of his compassion for his patients, he initiated all sorts of projects to improve the quality of life in the city, including the collection of waste water.

Global contribution
World Waternet, Netherlands Water Partnership and Aqua for All initiated the biennial Sarphati Sanitation Award in 2013 to honor the outstanding contribution of individuals or organizations to the global sanitation and public health challenge through entrepreneurship.

The Sarphati Sanitation Awards will be handed out for the third time during the Amsterdam International Water Week later this year in October.

Stimulating entrepreneurship
This year the focus will again be on entrepreneurship. The recommendations for this years' nominations are: Keep the focus on urban sanitation – open defecation in cities is increasing and focus on the challenge of small cities which especially in Africa are growing very fast.

And keep stimulating entrepreneurs but acknowledge the role of public servants, nominate individuals who create value out of what was hitherto regarded as waste and thereby improve health and do this on a sizeable scale.

dws-a4a-sarphati-award-2015-laan-beukel-350px Aart van den Beukel (right) of Safi Sana receives the 2015- Sarphati Sanitation Award for young entrepreneurs from mayor Eberhard van der Laan (left) of Amsterdam.

Previous winners
In 2013 the award was won by American-based organisation Sanergy for the development of its low-cost 'Fresh-life' toilet.

In 2015 there were two award winners. Dr. Kamal Kar of the CLTS Foundation was awarded for Lifetime Achievement in stimulation of the demand for sanitation. As for the Young Entrepreneurs category, Safi Sana was recipient for its processing of faeces in Ghana.

In 2016 the Toilet Board Coalition screened around 100 entrepreneurial sanitation initiatives. The Bill & Melinda Gates Foundation and The World Bank both are active promoters of sanitation as a business.

About Samuel Sarphati
Samuel Sarphati (Amsterdam, January 31, 1813 – June 23, 1866) was a Jewish doctor, chemist, philanthropist and entrepreneur who left an indelible mark on Amsterdam.

Fleet Cleaner completes first hull cleaning of Dutch naval ship Karel Doorman http://www.dutchwatersector.com/news-events/news/23563-fleet-cleaner-completes-first-hull-cleaning-of-dutch-naval-ship-karel-doorman.html dws-fleet-cleaner-karel-doorman-770pxDutch startup company Fleet Cleaner has announced that its bunker saving Fleet cleaner system has completed its first hull cleaning trial, cleaning the hull of the largest vessel of the Royal Netherlands Navy, HNLMS Karel Doorman.

In the Dutch port of Den Helder, the fouling of the marine vessel was removed by using Fleet Cleaner’s special designed remotely operated robot.

In March this year the company expects to launch a ship hull cleaning facility in the port of Rotterdam. This service will be offered by OH Ship Cleaning.

dws-fleet-cleaner-karel-doorman2-350px  The robot with its three domes scrubbing the hull with water. The removed fouling is collected.

Under and above water
The cleaning of the HNLMS Karel Doorman was unique since both under and above water cleaning was performed by the scrubbing robot. Due to loading and unloading, up to 20 percent of the fouled surface can be above the waterline in port.

The robot is able to clean a vessel during loading and unloading in ports. Due to the use of controllable high pressure waterjets, the coating is not damaged during the cleaning process.

According to Fleet Cleaner this has been confirmed by coating experts during the Karel Doorman cleaning with several coating measurements.

All removed fouling is captured by the robot and filtered by the support system, resulting in an environmental friendly hull cleaning solution.

Star-shaped robot
With a diameter of 1.80m and a sturdy steel frame, the robot can stand up to the heavy work for which it was designed.

The star-shaped frame supports three domes with rotating water jets, which spray the deposits away from the underside, while powerful magnets hold the machine against the hull.

An operator controls the robot from the shore or from another ship, which also collects and purifies the dirty water.

German government helps to scale up nature-based coastal restoration in Indonesia http://www.dutchwatersector.com/news-events/news/23522-german-government-helps-to-scale-up-nature-based-coastal-restoration-in-indonesia.html dws-wetlands-germany-demak-permeable-dam-770pxWetlands International announced that International Climate Initiative (IKI) of the German Environment Ministry (BMUB) has granted financial support to scale up a running pilot which aims to restore the eroded coast in the district of Demak, Central Java, Indonesia.

The German IKI initiative promotes healthy wetlands around the world as part of its ecosystem-based adaptation to climate change portfolio.

This grant supports replication of the Building with Nature concept that is currently used by Wetlands International in the coastal restoration pilot in Demak.

dws-wetlands-germanu-demak-scheme-350px  The concept of Building with Nature is based on the wisely use of natural coastal processes (illustration:JAM Visueel Denken).

Building with nature concept
The concept of Building with Nature is an innovative approach to coastal and water management challenges. It makes the services that nature provides an integral part of the design of hydraulic infrastructure.

This type of coastal restoration is an alternative to traditional hard infrastructure concepts which have proven ineffective along unstable muddy coastlines and fail to provide the multiple benefits that nature can provide.

Sediment trapping
The coastal restoration pilot in Demak involves construction of permeable sediment trapping structures to rehabilitate the mangrove belts, and the much-needed transformation of the aquaculture sector towards sustainable shrimp production, to ensure local income and prevent the future renewed loss of mangroves.

Mobilising replication
The IKI initiative supports this Building with Nature concept to scale up in Indonesia by mobilising knowledge institutes to provide trainings on a broad range of measures applicable.

This will also include the setup of a help desk facility that provides on-the-job guidance on all aspects of the project life cycle.

New aspects under the IKI funded programme include integrated water management planning and demonstration activities that offer an alternative to the deep ground water extraction which is currently causing land subsidence.

For example, restoration of rivers enables freshwater use for aquaculture and simultaneously allows distribution of sediment on land to mitigate subsidence.

dws-wetlands-germanu-demak-aerial-350px Aerial view of the sediment traps along the coast of Demak and the mangrove forest that can gradually take over the role of the dams and attenuate the waves and keep the sediment in place.

Partnership and donors
The Demak-project is coordinated by Wetlands International on behalf of the Ecoshape consortium and includes partnership with the Ministry of Marine Affairs and Fisheries (MMAF), Ministry of Public Work and Human Settlement (PU), the Diponegoro University, Dutch research institute Deltares, Wageningen University, water education centre Unesco-IHE, Dutch consultancy firm Witteveen+Bos, German engineering firm Von Lieberman, and local communities.

The project is financial supported by the Dutch Sustainable Water Fund, the German Federal Ministry for the Environment (BMUB) as part of the International Climate Initiative (IKI), Waterloo Foundation, Otter Foundation, Topconsortia for Knowledge and innovation, and mangroves for the future.

VEI and Unesco-IHE support regional training of staff African water utilities http://www.dutchwatersector.com/news-events/news/23510-vei-and-unesco-ihe-support-regional-training-of-staff-african-water-utilities.html dws-vei-unesco-uganda-work-770px
Dutch-based organisations Vitens Evides International and Unesco-IHE agreed with Uganda’s National Water and sewerage corporation (NWSC) to strengthen the position of the International resource center to become a regional training center for staff of water utilities in Eastern Africa. A tripartite cooperation agreement was signed in Delft, the Netherlands on 16 January.

Capacity building for African water utilities
Cooperation of the three parties will focus on undertaking joint capacity development programs and joint applied research on relevant topics related to water utility management.

An important element is to strengthen the International Resource Center (IREC) of NWSC, which provides training to staff of NWSC and other water utilities.

By strengthening IREC, the centre can become a regional training and knowledge center catering to staff of water utilities in (Eastern) Africa.

dws-vei-unesco-uganda-mugisha-holtzwarth-schouten-350px   Managing director dr. Silver Mugisha of NWSC (left), rector dr. Fritz Holzwarth of UNESCO-IHE (middle) and CEO dr. Marco Schouten of VEI (right) on occasion of signing of the tripartite agreement.

Three different parties
The three parties of this cooperation agreement are quite diverse. NWSC is Uganda’s national water utility mandated to operate and provide water and sewerage services in 174 towns in the country. It has been globally recognized as a utility which has been able to achieve remarkable performance improvements over the past two decades.

Unesco-IHE is the largest graduate water education facility in the world, with a long history of capacity development for water supply and sanitation in Africa.

Vitens Evides International (VEI) is the vehicle for the international corporate social responsibility agenda of six Dutch water operators and supports peer water operators in Africa and Asia on a not-for-profit basis towards realizing SDG 6 (ensuring universal access to water and sanitation).

Common mission
Although their different approaches and expertise, NWSC, Unesco-IHE and VEI share a common mission: to improve the capacity of water utilities to provide water supply and sanitation services.

Their diversity allows the partnership to combine operational and practical utility management know-how with capacity development and applied research expertise. This makes the partnership highly relevant for addressing the challenges existing in the African water supply and sanitation sector.

Dutch royal couple visits exhibition on flood protection in Dessau, Germany http://www.dutchwatersector.com/news-events/news/23430-dutch-royal-couple-visits-exhibition-on-flood-protection-in-dessau-germany.html dws-de-nl-dessau-king-lodderitzer-770pxDutch king Willem-Alexander and queen Máxima attended a German-Dutch exhibition on flood protection technology related to the restoration of the Elbe river, following the massive floods in 2002 and 2013.

The exhibition took place in the Unesco world heritage Kornhaus building on the banks of the Elbe river in Dessau, Germany on 10 February. It was held on occasion of a Dutch trade mission and a four-day visit of the royal couple to Germany.

The participants exchanged views on the development of tools for real time monitoring of water levels, early flood warning systems and flood evacuation information to residents.

The latter is still controversial as its requires authorities to acknowledge that – despite all protection measures that have been taken – there always remains a flood risk, no matter how small.

dws-de-nl-dessau-dalbert-350px  Saxony-Anhalt environmental minister Claudia Dalbert favours construction of more retention areas along the Elbe river.

More retention capacity along Elbe river
The royal couple was accompanied by Environmental minister Claudia Dalbert of Saxony-Anhalt and Infrastructure and the Environment minister Melanie Schultz van Haegen of the Netherlands.

Saxony-Anhalt minister Claudia Dalbert reminded the German and Dutch participants of the exhibition of the urgency to develop tools to prevent river floods. Large areas in her state were flooded in 2002 and 2013. The dike breach in 2013 costed her federal state of Saxony-Anhalt 1.7 billion euro she said.

Dalbert praised the new German national flood protection programme that includes some 60 projects in Saxony-Anhalt.

“In four years’ time some 532 million euro will be invested”, she continued. “This will include many technical measures, but we need to balance these with nature-based measures. By relocating our dikes we intend to increase the retention capacity with 10.000 hectare.”

dws-de-nl-dessau-schultz-maxima-350px Dutch queen Máxima (second right) and Dutch minister Schultz (second left) are informed on the new flood prevention plans by Saxony-Anhalt.

Sharing experiences
Dutch minister Schultz offered the assistance of Dutch flood experts that have been involved in the Room for the River programme. This programme included some 30 projects along the Rhine river, many of which were based on dike relocation.

“We have fifteen years of experience now”, she said. “and the results are already visible. Our flood plains are not only safer, they even look nicer.”

Never 100 percent safe
German and Dutch flood experts concluded that despite all flood prevention measures taken, some residual risk will always remain.

The Dutch firm HKV developed an app that can be used by residents in flood prone areas to predict the potential water levels in case of a flooding.

According to science director Bas Kolen at HKV most flood early warning tools have been developed to be used by professionals at water boards or disaster relief organisations. “Our app is specially made for residents. For every postal code in the Netherlands, the app shows the probability of flooding including the depth of the flooding at the given location”, he explained.

For the occasion of the exhibition, HKV developed a German version of the app, called Uberschwemm Ich?.

dws-de-nl-dessau-kolen-dalbert-couple-350px  Bas Kolen of HKV explains the Uberschwemm Ich? app to minister Dalbert and the Dutch royal couple.

Linking water levels to flood risks
At the exhibition Bas Kolen held a duo presentation to the Dutch royal couple together with Frank Schreiter, Landesbetriebes für Hochwasserschutz und Wasserwirtschaft (LHW) of Saxony-Anhalt.

Schreiter showed the national Hochwasser portal that provides real-time water levels at some 1.600 river locations. “Last year we also introduced an app for residents to check for the actual water levels”, he explained.

Both Kolen and Schreiter said to be interested to explore a possible combination of their apps in order to further increase the flood risk awareness and self-reliance of communities.

Other Dutch exhibitors were:
● Antea Group – consultancy
● Arcadis – consultancy
● Deltares – specialised research institute
● EcoLoss – tube flood barrier
● Hillblock - specially shaped dike stones
● Hyflo - self closing flood barrier
● I-real - real time data systems

German and Dutch river flood protection benefits from more mum, less dad http://www.dutchwatersector.com/news-events/news/23386-german-and-dutch-river-flood-protection-benefits-from-more-mum-less-dad.html dws-de-nl-dad-mum-socher2-770pxBoth in Germany and the Netherlands flood mitigation measures are implemented quicker when residents are involved right from the start. At a special organised flood seminar it proved that in both countries such an early citizen’s involvement is crucial for the continuation of flood protection schemes. Or as David van Raalten of Dutch consultancy firm Arcadis called it: ‘we need less decide-announce-defend and we need more meet-understand-modify’.

The seminar took place in Grimma, Germany on 9 February on occasion of the Dutch trade mission to East Germany.

Strategic gap
Professor dr. Martin Socher (on top photo), Saxon State ministry of the environment and agriculture, shared his experiences on the flood protection measures that have been taken, following the big floods of the Elbe river in 2002, 2010 and 2013. “Our state was under great pressure to act quickly and we listed 1,600 measures to minimize the potential damage of new floods”, he told.

According to Socher, the implementation of some measures started immediately but others were heavily delayed. “Soon we faced a drop in the number of projects and we were criticised for this delay”.

Socher called this the strategical gap. “No reconstruction without a strategy”, he advised.

dws-de-nl-dad-mum-grimma-door-350px Voluntary fire brigade of Grimma demonstrates the closure of one of the floodgates to the German-Dutch participants of the seminar.

Two floods of the century
It was no coincident the seminar took place in Grimma. The city’s old town centre on the left bank of the Mulde river, a tributary of the Elbe, was completely flooded in 2002 and 2013. Grimma was hit by two 100-year flood events in eleven years.

A special commission draw up a scheme that foresaw in a 3 m high monolithic concrete wall. The residents heavily opposed the idea however, as they did not want to lose contact with the river. The scheme needed a full revision.

With a few years delay the scheme to protect that city centre from a 100-year flood event is now finished.

The new scheme has been integrated in the town planning and consists of new 2 km long structure made up of four large historic buildings of which the walls have been retrofitted as main elements of the flood defence structure. In between these buildings, various 1,3 m high concrete walls have been constructed, as well as 78 mobile closures, including mobile defences and hinged gates.

Clear goal
At the flood seminar Deputy director general for Water and spatial planning at the Dutch Ministry of infrastructure and the environment, Roald Lapperre summarized his lessons from the Dutch Room for the River programme to increase the discharge capacity of the Rhine river.

The programme started in 2005 and includes over 30 measures. The last two are now under construction.

“It is important to have a clear goal”, said Lapperre. “It gives the reconstruction a focus. Furthermore, Lapperre mentioned the need to make good law and to have good governance with an adequate budget.

“Above all”, said Lapperre, “the Room for the River programme has shown that a flood prevention programme benefits from an integrated approach involving authorities at different levels and stakeholders, such as businesses and residents.”

“Bring out the best and improve your plans with their knowledge of the local situation and their interest. Include them in the planning phase and do not confront them with an almost finished plan”, was his advice.

Scoping part
European director water management David van Raalten at Arcadis told his firm developed a tool called Resilient pathways. “It starts with a scoping phase”, he explained.

“It widens the perspectives and helps to prioritise the most urgent measures. It can also help to find more financial resources by engaging more stakeholders."

Van Raalten advocated to first meet the residents and involve them in the planning phase. “Let them advise you and modify your plans. Avoid you have to defend an almost final plan.”

He concluded with the call for more mum, less dad. “We need less decide-announce-defend and we need more meet-understand-modify”.

Canadian-Dutch cooperation on resilient cities starts in Toronto http://www.dutchwatersector.com/news-events/news/23343-canadian-dutch-cooperation-on-resilient-cities-starts-in-toronto.html dws-canada-nl-resilient-cities-signing-730px
Dutch businesses, research institutes and governments will cooperate more closely with Canadian counterparts on sustainable development of cities.

The Dutch ambassador in Ottawa, Henk van der Zwan (right on top photo), and the Canadian ambassador in the Netherlands, Sabina Nölke (left), formally launched the newly initiated Canadian-Dutch cooperation on 3 February.

The Dutch partnership for resilient cities in Canada will combine the water and energy sectors with integrated urban development and the creative industries. It will focus on Toronto first, and then expand to other cities in Canada.

Migration to cities
Worldwide more and more people are moving to cities, so there is an ever growing need for solutions for issues to do with energy supply, smart infrastructure and mobility.

To keep cities resilient, Dutch companies, research institutes and governments combine their efforts to deal with these issues and develop solutions together.

Example to Canada
This successful Dutch approach in New York – after hurricane Sandy – and in New Orleans – after hurricane Katrina – did not go unnoticed in Canada.

The combination of knowledge and experience, while working with local stakeholders, is considered unique and valuable for Canadian cities.

Combination of disciplines
The partnership for resilient cities combines various disciplines: special strategies, urban systems, energy, water and land.

The initiative will build upon the positive experiences with Dutch-Canadian co-operation.

Canada and the Netherlands have worked together on urban development projects in the past, such as Waterfront Toronto and Blachford Edmonton.

Safi Sana installs new digester to expand its waste conversion capacity in Accra, Ghana http://www.dutchwatersector.com/news-events/news/23334-safi-sana-installs-new-digester-to-expand-its-waste-conversion-capacity-in-accra-ghana.html dws-safi-sana-full-installation-nijhuis-770pxSafi Sana Ghana Limited Company is expanding its faecal sludge treatment facilities in Accra by processing additional waste streams such as solid waste from the Ashaiman marketplace and the Accra abattoir. This enables Safi Sana to generate more energy that can be supplied to the national grid.

For this the company completed a second large digestion and cogeneration plant (see top photo) supplied by Dutch company Nijhuis Industries.

The social enterprise runs a simple model that sees it collect faecal substance and solid waste, pass them through its factory machines to manufacture organic fertilizer for agricultural purposes, and energy to sustain the national electricity grid.

More megawatts
“We have a large anaerobic digester”, explained Country manager Raymond Ategbi Okrofu at Safi Sana Ghana, “which has room for all the different strings of waste so it goes through the process of fermentation and the gas is produced, and we direct the gas to power a generator”.

“Presently we are doing almost 1.6 megawatts on a daily basis; but there is the capability to do more if we have clean waste and we enlarge the size of the digester”.

Water re-use
To complete the circular system Safi Sana re-uses the water that is collected from the digester drying beds. This water is used as irrigation water – free of pathogens, full of nutrients - to grow vegetable seedlings in its own greenhouse. The home grown organic fertiliser is used to stimulate the growth. The type of seedlings are selected in close consultation with local farmers and market queens.

Replicating to other regions
Okrofu at Safi Sana Ghana said the company’s model to process several waste stream, including the faecal matter from public toilets, is useful and can be scaled or replicated in different regions of the nation.

“Being the initial plant, we were a bit reserved in our design, it can be designed to handle any quantity of waste, but the first plant we have here, it is designed to have 30 metric tons of waste on a daily basis”, he said.

Conglomerate of partners
The technology being used at the company is imported from the Netherlands, and is a scheme of Aqua for All in a conglomerate of commercial and public partners, including Royal HaskoningDHV, Wereld Waternet, African Development Bank and Dutch government, who raised the capital needed to establish the project.

According to Mr. Okrofu, building a similar plant in other regions of the state may cost less, owing to the avoidance of costs such as registration of business and other related services.

Having spent almost three years to finally establish and officially begin operation of the waste management business after a phase of piloting, Safi Sana is optimistic that crafting another system to serve the same purpose on a superior scale, will take less than a year to finish.
