The pilot plant has originally been built to produce electricity from mixing salt and fresh water, using reverse electro dialysis (RED) with special designed membranes. With a different membrane stack configuration the pilot plant can directly produce green hydrogen.

dws-redstack-plant-afsluitdijk-350px  REDstack's 50kW demo plant on the closure dam Afsluitdijk produces electricity since 2014.

Smaller membrane modules
In fact, right from the start in 2014, the pilot plant already produced a small amount of hydrogen as an unintended side effect of the RED process. This side effect was considered as an inevitable loss as it did not contribute to the production of electricity.

Because of the growing demand for hydrogen, as a replacement for fossil fuels, REDstack decided to rearrange one of its membrane stacks. Instead of stacking many membranes into one big module (on top photo), the new configuration has a smaller amount of membranes in the modules, but the amount of modules is bigger.

dws-redstack-hydrogen-hack-350px Director Pieter Hack of REDstack says that he is looking for a business partner to roll out the fully green hydrogen to the market as a fuel. 

Huge potential
According to REDstack, a Blue Energy plant on the mount of the river Rhine estuarine, where the fresh river water meets the salt water of the North Sea, has the potential to produce - free of CO2 - 1.6 billion Nm3 of H2-gas.

The firm expects its first hydrogen to be produced by mid 2019. "Our next focus is on the delivery conditions of the hydrogen as a fuel. It has to be clean and deliverable at 700 bar", said director Pieter Hack of REDstack.

"We need to find out what is needed to upgrade our production to meet the specifications of the clients", added Hack. "We are actually looking for business partners for this roll out to the energy market".

REDstack is in an advanced stage to build a 1 MW Blue Energy demo plant along the Dutch coast near Katwijk. At this location the plant can use salt water from the sea and fresh water from an inland drainage channel. The Blue Energy demo plant will be developed to produce electricity.

The firm recently started talks with the Port of Rotterdam on a REDstack plant for fully green direct production of hydrogen.

About REDstack
REDstack is a Dutch spin-off company from water technology research centre Wetsus and was founded in 2005. It's mission is to develop and commercialise reverse electro-dialysis (RED) and related technologies. Theoretically, with 1m3/s river water and an equal amount of sea water approximately 1 MW of renewable electricity can be recovered.

The first pilot plant is operational on the closure dam Afsluitdijk since 2014, producing 50kW of electrical power.

Rotating flood barrier officially opened to protect town of Ipswich, UK https://www.dutchwatersector.com/news-events/news/35608-rotating-flood-barrier-officially-opened-to-protect-town-of-ipswich-uk.html dws-volkerstevin-ipswich-rotating-gate-750pxEnvironment Agency’s new tidal flood defence barrier for Ipswich has been officially opened and will better protect homes and businesses in Ipswich over the next 100 years from the increased flood risks associated with climate change.

The flood barrier’s centrepiece is a 200-tonne rotating gate that moves upwards out of the sea floor into the closed position.

The flood barrier has been built by VBA - a joint venture between VolkerStevin, Boskalis Westminster and Atkins - as main contractors and the 9 m tall gate has been constructed in Rotterdam by Hollandia.

dws-volkerstevin-ispwich-coffey-howard-350px  Environment Agency Chair, Emma Howard Boyd (l) & Floods Minister Thérèse Coffey (r) at the opening of the new Ipswich Tidal Barrier.

Sea level rise
The flood gate has a design similar to that of the Thames Barrier and meets the protection standards based on the government’s most recent prediction that sea levels could rise by up to 1.15 metres, increasing the risk of tidal surges affecting those living on the coast.

The barrier gives a better flood protection to more than 1,600 homes and 400 businesses in Ipswich for the next hundred years.

Boost to local economy
Aside from this protection, Ipswich’s new flood defence scheme has the added advantage of helping to boost the local economy through freeing up hectares of land for regeneration.

dws-volkerstevin-ipswich-aerial-350px One of the first activities by VBA was the construction of piled flood defence walls on either side of the entrance of the navigation channel.

On the occasion of the official opening Floods Minister Thérèse Coffey said: "This important new flood scheme, which has received nearly 55 million pound of government funding, secures the future of hundreds of local businesses whilst creating 4,000 jobs to boost the town’s economy."

"I am delighted the Government is investing so significantly in the county town of Suffolk and its future prosperity", Coffey said.

Local cooperation
Environment Agency’s chair, Emma Howard Boyd, highlighted the close cooperation with local parties. "The Environment Agency worked closely with the local community, the council and businesses to design and build a scheme that provides a greater level of protection for the town."

According to Howard Boyd the scheme is an important step forward for the six year, 2.6 billion flood investment across the whole country.

The Ecodelta is a trailing suction hopper dredger and its engines use natural gas, producing low NOx emissions compared traditional fuels such as to heavy oil and marine diesel oil. The dredger had its ceremony of baptism in Rotterdam on 11 January.

dws-kamp-ecodelta-baptist-rotterdam-350px Baptism ceremony in port of Rotterdam on 11 January. 

Silted up places
It is the first time that a LNG powered dredger, carries out the maintenance in the Eemshaven. Eventually the entire port will be at the desired depth again. The work is expected to be completed after approximately 1.5 weeks, with the next dredging campaign taking place in October.

Lower NOx-emission
By opting for LNG as fuel, Ecodelta emits 20 percent less CO2 and reduces that of nitrogen oxide (NOx) by 85 per cent. Sulphur and particulate matter emissions are reduced to virtually zero.

The emissions meet the strict standards set by the authorities of the Port of Rotterdam where Van der Kamp will station its Ecodelta most of the time for ongoing maintenance. The ship is 134 m long and has a capacity of 6000 m3.

TwynstraGudde wins tender for coastal zone management project on Java, Indonesia https://www.dutchwatersector.com/news-events/news/35564-twynstragudde-wins-tender-for-coastal-zone-management-project-on-java-indonesia.html dws-twijnstragudde-iczm-rembang-aerial-770pxLeading partner TwynstraGudde of a consortium with Witteveen+Bos Indonesia, Akvo and the local Indonesian partner Bita, announced that the consortium has been commissioned for a project on integrated coastal zone management (ICZM) for the province of Central Java.

The consortium is to advise the authorities on a long-term strategy that includes the principles of ICZM. A kick off meeting is planned for March and following a period of familiarisation, the principles are to be applied in two years time.

dws-twijnstragudde-iczm-buidling-dam-demak-350px  Construction of permeable bamboo piled dams with brush wood holds many aspects of sustainable coastal zone management as it involves local communities. On top photo are the permeable dams at Rembang allowing sediment from the sea to pass and hold it back (right).

Sustainable coastal development
"We are delighted that we have won this tender", said advisor Susan Arts of TwynstraGudde Water Consultancy. "With this project we really hope to contribute to the future of Central Java."

Arts: We will help the province of Central Java to familiarize itself with the principles of Integrated Coastal Zone Management."

Ensure lasting effects
In Java many people live and work at the coast. The rapid population growth and the increasing urbanization are taking their toll. This causes all sorts of problems on the north coast of Java, such as land subsidence, a decline in biodiversity and more vulnerability to flooding.

The government of the Central Java Province wants to respond with a sustainable coastal development with a lasting effect, including a strategy, organisation and management plan.

The Dutch-Indonesian consortium will assist the local authorities with knowledge development and capacity building to implement ICZM.

dws-twijnstragudde-iczm-demak-350px Training for Trainers workshop in Semarang in January as part of the Building with Nature Indonesia programme, run by Deltares and Delft university of technology.

Dutch-Indonesian partnership
In 2016 the Dutch and Indonesian government signed a Letter of intent for cooperation in activities in coastal restoration and revitalization of the North coast of Java.

One of the icon projects is the coastal restoration near Demak where local communities build wooden permeable dams to catch silt sediments for mangroves to return.

The Netherlands Enterprise Agency (RVO) tendered the ICZM-project so consultancy firms can assist the province of Central Java in stopping the erosion in a sustainable way.

The consortium that won the tender includes consultancy firm TwynstraGudde, contributing with its experience in learning development. Consultancy firm Witteveen+Bos is an engineering firm with technical knowledge and experience with projects in Java.

Foundation AKVO will develop a special section on its Akvodepia with information on integral coastal management for the province and all stakeholders involved. The content of the Wikipedia-based portal will be strongly visualised.

All 115 day’s worth of monitoring and collecting test data from the prototype while it was at sea, are now being recovered from its sensors (on top photo: head of IT on location in Hawaii). The team twittered that the data will play a crucial role in the upgrade and the repair of the 570 m long boom.

dws-ocean-cleanup-hawaii-arrival-350px  Arrival of Wilson 001 prototype in Hilo Bay, Hawaii, on 18 January.

Analyses brake off and re-design
According to the twitter account the team is still optimistic on the redeployment of an updated version of the prototype. How long that will take is unknown at present as it depends on the analyses of the break off and the extend of the re-design.

Learning by doing
In several interviews CEO Boyan Slat reacted on the setback by pointing out that the collection system is experimental and has never been tried before. The fastest way to find out if it works, was by going out to the ocean and learn by doing, Slat told.

The first deployment learned that the U-shaped boom did capture the plastic but it also floated out again. The team was about to experiment with a wider U-shape, when the end section broke off and the boom had to return to the harbour.

The joint proposal for the 80 ha riverfront area was awarded first prize unanimously by the judges. The award concluded a three stage international competition that started with four international teams.

dws-kcap-shenzhen-birdeye-csilkroad-350px Birdseye impression of the new waterfront along the Longang river.

Attractive area for working and living
The competition called for a comprehensive transformation strategy and framework design for the entire 46 km2 Longgang waterfront area. This former industrial area is undergoing a rapid transformation towards an attractive and innovative area for working and living.

The transformation strategy focusses on a strong green-blue network with ´river-anchors´ as new thematic centers on transport hub locations.

Macro, meso and micro scale
With an essential task in water management on district level, the Longgang river is the backbone of the team's transformation framework.

On the macro scale, the river is connected to four mountains with seven river corridors, and five ecological zones which are transformed using a corresponding toolbox.

On the meso scale, it is divided into four parts according to their different spatial, functional and environmental features. Different spatial strategies are tailored for each section.

On the micro scale, diverse embankment types are designed to increase connectivity, to provide an active space for the river and people, and to enhance ecology and landscape values.

dws-kcap-shenzhen-different-levels-350px KCAP and CAUPD integrated different aspects at three different scales in one overall design.

Water robustness
The masterplan and urban design strategies are supported by hydraulic engineering measures for stronger water robustness, resilience and further implementation.

Double water interception defence lines, including rainwater-sewage diversion network and river sewage interception pipe, are planned and a combined purification system with sewage plants and wetlands is utilised.

Waterway dredging and expansion are proposed according to a flooding calculation, and the concept of sponge city is combined with design details such as materialisation and vegetation design.

KCAP and CAUPD and team Arcadis, Landscape architects & urbanists, CallisonRTKL and Shenzhen University were the two remaining finalists in the challenge. In the previous phase team Arcadis was selected as winner. In this final round KCAP and CAUPD turned out as overall winner.

Kick-start WaterworX project in Mekong Delta to secure water supply services https://www.dutchwatersector.com/news-events/news/35402-kick-start-waterworx-project-in-mekong-delta-to-secure-water-supply-services.html dws-vei-waterworx-vietnam-group-720px
Dutch water companies signed a Partnership Agreement with water companies in the Hau Giang, Soc Trang and Can Tho, in the South Western Mekong Delta on 23 January.

The agreement is part of a Dutch WaterworX project - managed by VEI - to support the Vietnamese water companies in the river delta to maintain their future water supply in the view of upcoming climate change challenges. Can Tho has two companies that will join the project’s first phase, while Hau Giang and Soc Trang also have one each.

dws-vei-waterworx-mekong-treatment-280px Water supply in the Mekong Delta is currently at a good level but soil subsidence threatens the fresh water resources that are currently used by the water companies.

Upgrading supply schemes
Although coverage and service levels are relatively good in Vietnam, serious challenges low lying river delta, including land subsidence, saline intrusion, reduced availability of groundwater and pollution of surface water pose heavy risks on the future water supply.

A regional approach for upgrading, expansion and modification of supply schemes is necessary. The current institutional and legislative landscape is fragmented and not furnished to effectively cope with those upcoming climate challenges.

Enhance operational capacity
According to Folkert de Jager (fourth from the right on top photo) of VEI, the WaterworX project will help enhance the operational capacity of water supply firms, focusing on reducing revenue losses, as well as improving water quality and saving power.

Also part of the project is the coordination to build resilient future plans. In the second and third phases, the project may expand the collaboration with other water firms in the Mekong Delta facing similar problems, such as Bac Lieu, Ca Mau, and Kien Giang.

De Jager: "Hopefully, the project will contribute to promoting economic growth in the Mekong Delta region, where water plays a significant role in local agriculture."

The intention for phase two and three of the WaterworX programme, which runs until 2030, is to scale up the project to the entire South Western Mekong Delta, improving water supply for 10 million people.

dws-vei-waterworx-mekong-delta-nairobi-350px WaterworX also conducts projects in Africa, such as here seen in Nairobi where pre-paid water meters are introduced.

About WaterworX
WaterworX is a public-private collaboration (2017-2030) between ten Dutch water companies and the Netherlands’ Ministry of Foreign Affairs to increase sustainable access to drinking water to 10 million people in 2030 in Africa, Asia and Latin America.

In the case of the Mekong Delta, the project covers a large area, with a total of about 10 million inhabitants for who the water supply can potentially be improved.

The Mekong Delta projects also addresses the sustainability of the water supply, aiming to adjustment of the water company’s operations to the effects of climate change, in this case soil subsidence. Without adjustments the water companies are expected to run out of business in about 30 years.

WaterworX is preparing substantial financial investments. Involving the World Bank and the Vietnamese government. Both have acknowledged that the partnership can contribute to an effective absorption of such investments in the Vietnamese water supply companies.

2 February 2019 is World Wetlands Day, this day marks the adoption of the Convention on Wetlands on 2 February 1971 in Ramsar, Iran. This year the organisers address climate change as the central theme.

Conservation of wetlands, by stopping the drainage, contributes to the capture of greenhouse gasses and reduces climate change. Their potential is enormous as they can hold more CO2 than for instance forests. Worldwide over 1,000 events will be held to celebrate this day and raise awareness for the wise use of this vulnerable type of landscape.

dws-wetlands-day-not-powerless-350px  The importance of wetlands is increasing, now also including the fight against  climate change and reduction of migration.

Many wetlands in the world are under pressure as a result of drainage to make other land use possible, in many cases agriculture.

Especially the drainage of peatlands leads to oxidation of the peat and the release of methane, a greenhouse gas. Drainage of wetlands has the potential of a CO2-bom and undermines the Paris Climate Agreement.

Blue carbon
Better management practices can help protect the storage of carbon and the ability of wetlands function as carbon sinks by absorbing CO2 from the atmosphere. There is also ‘blue carbon” that is stored by coastal wetland vegetation such as mangroves, seagrasses and salt marsh grasses.

… and much more
Wetland conservation is known for its protection of nature, but there is so much more.

Wetlands act as a natural sponge, absorbing and storing excess rainfall and reducing flooding. Along coasts mangroves can act as flood defences.

Wetlands can also help to prevent migration. Dried up wetlands mean that communities lose their fishery grounds. It leaves them without water to irrigate their farm lands.

Deprived from income, communities fall into poverty and makes people decide to move elsewhere.

Advanced mapping of Zambezi river by students to prevent floods and droughts https://www.dutchwatersector.com/news-events/news/35355-advanced-mapping-of-zambezi-river-by-students-to-prevent-floods-and-droughts.html dws-tud-mapping-zambezi-aerial-erosion-770pxFive students of the Delft University of Technology are in Zimbabwe to map and analyse the Zambezi river in cooperation with the University of Zimbabwe.

The overall goal of this mapping is to be able to enhance the water, food and energy security in the Lower Zambezi river through a better understanding of the rainfall-runoff behaviour in the river catchment.

dws-tud-mapping-zambezi-savenije-350px Former Delft professor Huub Savenije spent much of his time studying the Zambezi river in great detail.

Accurate flow estimates
In the Lower Zambezi, (Zambia, Zimbabwe and Mozambique) populations suffer frequently from severe floods and droughts. Dealing with these problems relies on the ability to accurately estimate the flows entering the river.

This is a major challenge because most of the rivers entering the Zambezi are ungauged, meaning there are no flow records.

A better understanding of the rainfall-runoff behaviour is crucial for a better operation of Kariba and Cahora Bassa dams, reducing flood hazard of affected communities and securing energy and agricultural production.

Advanced hydrological model
For that purpose, the research will develop a landscape and ecology-based hydrological model fed by remotely sensed rainfall and evaporation.

The latest innovations in water resources assessment will be used, such as drones for topography based river rating. Also Distributed Temperature Sensing (DTS) will be used for determining evaporation from indigenous forests. Accelerometers for interception measurement and micro-wave links are to determine the water content of vegetation. Improved dam operation will contribute to achieving the sustainable development goals on water, energy, environment, flood and human settlement.

The research project is carried out jointly by the University of Zimbabwe, Dutch water supply company Waternet and Delft university of technology, in close cooperation with end users Zimbabwe National Water Authority (Zinwa), Zambian Water Resources Management Authority (Warma) and Hydro Cahora Bassa (HCB).

IGRAC, IWMI and Botin make book on good groundwater governance free downloadable https://www.dutchwatersector.com/news-events/news/35327-igrac-iwmi-and-botin-make-book-on-good-groundwater-governance-free-downloadable.html dws-igrac-book-governance-resettling-sudanese-returnees-770pxOne year after publication, the book 'Advances in Groundwater Governance' has been published online and is free downloadable, thanks to sponsoring by International groundwater resource assessment centre (IGRAC), International Water Management Institute (IWMI) and Botin Foundation.

The book - published by Taylor & Francis Group - captures the complex dimensions of groundwater governance, and provides water industry professionals, decision-makers and local stakeholders with a suite of solutions for a heuristic approach to managing this extremely important resource.

dws-igrac-book-groundwater-governance-300px The book Advances in Ground Governance is now free readable.

In the preface the editors mention the phenomena of ‘hydro-schizophrenia’, a typical mental attitude of water managers who deal primarily with surface water, forgetting or neglecting groundwater. The phenomena popped up in scientific literature as an ‘illness’ as part of a case study in Spain. Key element is the fact that groundwater is invisible, and that the engineering structures for groundwater have little aesthetic beauty. The editors point out that the head of a well of 1,000 meters deep is practically invisible on the surface. This contrasts with the usual aesthetic splendour of hydraulic works for the use of surface water.

Good governance
In the book the team of five editors provides crucial and topical information for enhancing and safeguarding the huge benefits accruing from groundwater to humanity, and for preventing degradation of groundwater resources and of the interconnected ecosystems and environment.

They also focus on the increasingly important linkages between groundwater and other resources and sectors, and between local groundwater systems and phenomena or actions on global level; a number of case studies illustrate groundwater governance in practice.

IGRAC contribution
On IGRAC's behalf, PhD Researcher Kirstin I. Conti contributed to this book as co-author. Other editors were Karen G. Villholth (IWMI), Elena López-Gunn (ICATALIST and University of Leeds, Alberto Garrido (Universidad Politécnica de Madrid & Water Observatory of the Botín Foundation), and Jac van der Gun (Van der Gun Hydro-Consulting).

Moreover, together with CGIAR Research Program on Water, Land and Ecosystems and Botín Foundation (link is external), IGRAC was involved as sponsor of this book.

Pitch your water innovation at GES2019 Summit in The Hague https://www.dutchwatersector.com/news-events/news/35302-pitch-your-water-innovation-at-ges2019-summit-in-the-hague.html dws-ges2019-poster-770px
On 4 and 5 June 2019, the Netherlands and the United States will organise the ninth Global Entrepreneurship Summit (GES2019) in The Hague. It is the first time the summit will be held in Europe, bringing together the top scale ups of the world with investors, stakeholders, policy makers and experts from the industry.

Entrepreneurs with new solutions for the major issues in energy, water, food & agri, health and connectivity can pitch their inventions at the summit. The deadline to apply for a pitch is 1 March.

dws-ges2019-infographic2-350px The ninth edition of the Global Entrepreneurship Summit will take place in The Hague in June.

Will you be there?
Do you have a technological solution on agri-food, connectivity, energy, health, water that can transform the world? Is your company ready for investment and do you want to scale up internationally within five years?

Then come to GES2019 and pitch your solution to some 400 investors from around the world that are expected to come to The Hague.

Entrepreneurs and investors
Since the first summit, GES engaged 20,000 entrepreneurs and delivered 1 billion US dollar in new capital.

Over 1,200 entrepreneurs will be invited to attend GES2019. Of these, 400 are from the USA, 200 from the Netherlands, 200 from the rest of Europe and 400 from the rest of the world.

Some 400 investors from around the world are expected, as well as 400 opinion makers and government representatives. In addition, around 200 journalists will be present.

Water as special theme
One of the four special themes is water and the Netherlands Water Partnership (NWP) will take the lead in the scheme of this theme.

The two central issues are securing water supplies (infrastructure) and managing urban water issues (extreme weather events such as floods and droughts).

Managing Director Bianca Nijhof of NWP calls upon innovators to come to The Hague with solutions to solve the global issues of too much, too little or too polluted water.

Clear message by Dutch delegation at Davos: speed up climate adaptation worldwide https://www.dutchwatersector.com/news-events/news/35260-clear-message-by-dutch-delegation-at-davos-speed-up-climate-adaptation-worldwide.html dws-davos-rutte-panel-770pxDutch Prime Minister Mark Rutte and Minister Cora van Nieuwenhuizen of Infrastructure and Water Management plead for more action to adapt to climate change at the World Economic Forum in Davos, Switzerland.

Two specific items on the agenda of the Dutch delegation were the roundtable meeting of the Valuing Water Coalition and the preparations by the Global Commission on Adaptation for a global action programme to be presented at the UN General assembly in New York in September. The World Economic Forum took place from 22 – 25 January.

dws-davos-ranking-impact-2017-2019-350px All three latest Global Risks Reports clearly indicate a big concern amongst business leaders about climate change. In the 2019-edition, water crises ranks at a fourth place in terms of potential impact.

Risk perception
The latest edition of the  Global Risks Report ─ that is always published just before the meeting in Davos ─ again reported that business leaders consider climate change a major risk to the global economy.

Extreme weather events and the potential failure to climate mitigation and adaptation, rank in the global risk top 3 both for likelihood and impact.

The risk perception of water crises has increased. In 2018 it took a fifth place in terms of impact, compared to a fourth place in this year’s report.

Speed up on adaptation
At the World Economic Forum Dutch Prime Minister Rutte (middle on top photo at the Climate Leadership Forum) urged all countries to speed up their actions to adapt to climate change.

Dutch Minister Van Nieuwenhuizen emphasised that climate adaptation is important for countries to remain viable and economically prosperous. "In the Netherlands, national and local authorities jointly allocated 600 million for measures to protect us from flooding, extreme rainfall and periods of drought. This type of agreement between governments, but also with companies ensures that smarter investments are made in climate solutions and countries become resilient", Van Nieuwenhuizen said.

Meeting of GCA commission
In Davos, the commission of the Dutch-based Global Centre on Adaptation (GCA) talked about their preparations for an action plan to be presented at the UN General Assembly in September in New York.

The GCA commission with Bill Gates (founder of Microsoft), Ban Ki-Moon (former Secretary General at the United Nations) and Kristalina Georgieva (CEO World Bank), is working on the worldwide acceleration of climate adaptation.

"Worldwide we already see light points in climate adaptation", 'said Ban Ki-Moon in Davos. "Infrastructure that is being prepared for extreme heat, agriculture that is set up for prolonged droughts and inhabitants of vulnerable coastal areas that are protected. But the fact remains that this must be deployed faster and on a larger scale than we see today."

dws-davos-meeting-valuaing-water-350px Meeting of the Valuing Water Coalition with CEO board members of private, public, civil society and international organisations.

Better valuing of water
On 24 January, Prime Minister Mark Rutte hosted a roundtable on the five principles of the Valuing Water Initiative, to incorporate the water values of all stakeholders.

CEO's and board members of private, public, civil society and international organisations discussed how to value water better and act accordingly.

ING Head of Wholesale Banking, Isabel Fernandez, announced that her bank will partner with the Dutch Government in the Valuing Water Initiative for the coming three years. ING will support the initiative with its public and private network and financial expertise in the transformation to a water secure world.

First export of XBlocPlus armour units for breakwater of marine port Albania https://www.dutchwatersector.com/news-events/news/35245-first-export-of-xblocplus-armour-units-for-breakwater-of-marine-port-albania.html dws-dmc-xbloc-porto-albania-impression-770pxDutch company Delta Marine Consultants have signed a license agreement with Swiss company SEL AG for the use of XblocPlus in the Marina Porto Albania project. It will be the first international application of DMC’s latest version of XBloc armour units.

The Xbloc production is expected to start early 2019 and the objective is to complete the breakwaters by early 2020.

dws-dmc-xblocplus-unit-350px  XBlocPlus has been designed to achieve optimal interlocking between the blocks, providing more hydraulic stability.

Second high profile project
The blocks envisaged to protect the marina against severe storm waves in the Adriatic Sea are 2.5 m3 XblocPlus on the breakwater trunk in combination with 3 m3 Xbloc units on the breakwater head.

With six months after the market introduction, XblocPlus has already been selected for two high profile projects.

The first Dutch project with XblocPlus is the enforcement of the Afsluitdijk Project where the block is applied under the name Levvel-blocks, named after the Levvel consortium (Bam, Van Oord and Rebel) that will strengthen the levee on behalf of the Dutch national water authority Rijkswaterstaat.

dws-dmc-xbloc-porto-albania-twp-types-350px Impression of the combined use of the XBloc and the XBlocPlus on a breakwater.

Less concrete, less units
XblocPlus is a further development of the Xbloc which has been applied in breakwater constructions around the world over the past 15 years.

Compared to other blocks in the market, XblocPlus requires significantly less concrete and less blocks to cover the same breakwater.

Due to the similarity to roof tiles, the regular block placement of the new unit is fast, safe and efficient. It also gives breakwaters and shore protections a very smooth look.

In the Marina Porto Albania project both types will be used. The XblocPlus will be applied on the straight and mildly curved breakwater sections where the blocks can be placed fast and efficiently in the rooftile pattern whereas the flexibility of the original Xbloc unit will be used on the breakwater heads where it provides protection on the sharply curved surface area.

First MSC Zoe’s containers recovered from North Sea off Dutch coast https://www.dutchwatersector.com/news-events/news/35213-first-msc-zoe-s-containers-recovered-from-north-sea-off-dutch-coast.html dws-rws-container-salvage-geosund2-770pxTwo multipurpose off shore support vessels, the Geosund and the Atlantic Tonjer, have been chartered by container line Mediterranean Shipping Company (MSC) to raise sunken containers from the bottom of the North Sea and bring them to shore. MSC’s mega container ship Zoe lost 291 containers off the Dutch coast in a storm on the night of January 2.

Following a few days delay because of bad weather, the salvage operation commenced on 18 January. Geosund and Atlantic Tonjer managed to recover the first containers and other debris. MSC has pledged to bring all containers to shore, but this will prove difficult as many containers are expected to have been heavily damaged when they fell.

dws-rws-salvage-containers-msc-zoe-aerial-350px  Havoc aboard MSC Zoë on the morning after the storm, photographed by the Dutch coast guard. Of the 8,000 containers aboard, 291 had fallen off.

Cleaning up shores
Immediately after the incident debris started to wash up the barrier islands on the Dutch northern coast.

It took local water authorities, nature conversation group, military and many volunteers several days to clean up the beaches. This included the recovery of 18 containers that did not sunk immediately and washed up on the shores.

Meanwhile the Dutch national water authority started a search operation to localise all the containers that had sunck. This has been successful for 220 containers, meaning that at the moment 51 are still missing.

Around the clock
The crane grippers aboard the Atlantic Tonjer and Geosund are working around the clock to pick up any debris from the 25 to 30 m deep sea bed on the given locations.


One of the first containers picked up from the sea bed by the crane gripper of the Geosund. Visible on the side of the ship is the echo device (vertical yellow bar) that assists the crane operator to position the gripper more precisely.

The salvage operation first concentrates on a hot spot, some 20 km of the coast of the Dutch island Terschelling, where over 100 containers have been localised.

Both ships have been equipped with an echo device that assists the crane operator to position the gripper as accurate as possible over the detected debris.

Ship owner MSC bears full responsibility for the operation, with Dutch and German coast guards and Dutch national water authority Rijkswaterstaat providing assistance.

Currently sixteen ships are involved. Next to the Atlantic Tonjer and Geosund, the fleet includes guard and survey vessels.

Supply vessel Blue Bella shuttles back and forth, taking the recovered debris to the shore. This enables both salvage ships to continue their work.

Time pressure
The whole operation is under time pressure as the heavy containers will slowly sink into the sandy sea bed to be fully covered up by sediment.

The shipping company MSC assumes that it will take three months until all containers are salvaged, but in the worst case, it could also be six months.

Paques to equip Swedish paper mill with ICX anaerobic bioreactor for recovery of biogas from waste water https://www.dutchwatersector.com/news-events/news/35176-paques-to-equip-swedish-paper-mill-with-icx-anaerobic-bioreactor-for-recovery-of-biogas-from-waste-water.html dws-paques-gasum-nymolla-aerial-770pxPaques Europe signed a multi-million contract with Finish energy company Gasum for the supply of Biopaq ICX anaerobic bioreactors and a Thiopaq gas desulphurisation installation.

Gasum is to build a waste water treatment plant at the Nymölla paper mill operated by Stora Enso in Sweden. This plant will be equipped with Biopaq ICX and Thiopaq for the production of biogas. The contract was signed at the end of December 2018 and the start-up of the installation is expected in 2020.

Liquefied biogas production
Last year Finish energy company Gasum and Finish-Swedish producer Stora Enso signed a contract to build a biogas plant at Stora Enso’s Nymölla paper mill (on top photo) in Sweden. Gasum plans to produce Liquefied Biogas (LBG) and sell it as fuel for cars, buses, trucks, and ferries.

The Nymölla biogas plant project includes biogas production, upgrading and liquefaction. The expected LBG production of the plant is 220 MWh per day.

Well-known office paper
Located in southern Sweden, Stora Enso’s Nymölla Mill has an annual production capacity of 340,000 tonnes pulp and 485,000 tonnes woodfree uncoated (WFU) paper for office and postal use. Stora Enso’s well-known office paper brand Multicopy is produced in Nymölla.

The liquefied biogas production at Stora Enso’s paper mill fits Gasum perfectly as they want to contribute to the circular economy by processing waste and producing biogas and recycled nutrients in Finland and Sweden.

dws-paques-gasum-filling-station-ikea-350px Gasum processes food waste from IKEA into biogas that customers can use to fill up their car. Here, a filling station at the IKEA store in Espoo, Finland (Photo: Gasum ltd)

More biogas at higher load rates
Paques’ ICX anaerobic bioreactor is a new development in the Biopaq product line for the treatment of waste water.

In order to meet today's industrial customer's requirements, ICX-technology allows high volumetric loading rates. The 2-stage biomass retention prevents wash-out of biomass and high liquid velocities and high excellent mixing properties enables handling a wide range of industrial wastewater.

An ICX-reactor has a high biogas production from biomass. The additional treatment of the biogas in the Thiopaq gas desulphurisation installation upgrades the biogas for use in a gas engine or boiler of can be transported in a local micro gas grid.

Another possibility is the upgrading to biomethane, which can be brought into the gas distribution network,  as fuel for vehicles. The elemental sulphur, produced by Thiopaq can be used as a high quality fertiliser.

Fugro completes first deployment of airborne RAMMS data collection of Turks and Caicos Islands https://www.dutchwatersector.com/news-events/news/35155-fugro-completes-first-deployment-of-airborne-ramms-data-collection-of-turks-and-caicos-islands.html dws-fugro-ramms-turks-caicos-aerial-730px
Fugro has completed a land and sea data acquisition campaign over the Turks and Caicos Islands, a British Overseas Territory, marking the first commercial success of its new Rapid Airborne Multibeam Mapping System (RAMMS).

Working under contract to the United Kingdom Hydrographic Office (UKHO), Fugro deployed its new RAMMS airborne mapping system to acquire over 7,400 sq km of integrated, high-resolution data in the Turks and Caicos islands. The resulting deliverables will support updated nautical charts and coastal zone management activities in the region.

Next generation mapping
Launched in August 2018, RAMMS is a highly efficient, next-generation airborne bathymetric mapping system that uses multibeam laser technology to deliver industry-leading depth penetration and point densities.

The compact sensor is deployed from small aircraft and can be easily integrated with other remote sensing technologies for simultaneous collection of multiple complementary datasets.

dws-fugro-ramms-turks-caicos-350px  Image of a detailled RAMMS land and sea data collection as released by Fugro in August last year.

Single deployment
For the Turks and Caicos Islands project, this approach made it possible to acquire nearshore (bathymetry) and coastal (topography and imagery) data in a single deployment, producing a cost-effective solution and advancing Fugro’s sustainability goals by significantly reducing fuel consumption.

"After years of development, it’s extremely gratifying to operate RAMMS commercially and to demonstrate to clients the value that this cutting-edge technology can bring", said Mark MacDonald, Fugro Americas Marine Division hydrographic service line director.

High point densities
MacDonald referred to the massive Turks and Caicos Islands project as an example. "The system’s multibeam lidar capability allowed us to achieve point densities that otherwise would have required vessel-based surveys. With RAMMS, we were able to avoid that additional time and expense, and significantly reduce health and safety exposure."

Three other projects
Fugro is currently working on three additional RAMMS projects in the Americas region, one for UKHO in Belize, and two for the Canadian Hydrographic Society (CHS), in Quebec and Atlantic Canada. These projects are similar in scope to that of the Turks and Caicos Islands project, combining bathymetry, topography and imagery for maximum value to clients, serving both navigation and coastal applications.

Rijkswaterstaat opens mouth of Rhine and Meuse rivers for salmon https://www.dutchwatersector.com/news-events/news/35128-rijkswaterstaat-opens-mouth-of-rhine-and-meuse-rivers-for-salmon.html dws-rws-haringvlietdam-opening-770px-1Dutch national water authority Rijkswaterstaat opened for the first time one of the locks of the Haringvlietdam to let in salt water from the sea.

The opening - that took place on 16 January - allows migratory fish to pass the lock on its way from the North Sea to the upper parts of the Meuse and Rhine rivers in Germany, Belgium, France and even Switzerland. This marks the new Dutch water policy of Living with water and a more flexible management of the Dutch coastal zone.

dws-rws-haringvlietdam-aerial-350px  Higher tide on the North Sea (left) allows salt sea water - with migrating fish - to flow into fresh water lake Haringvliet (right). Only one of the 17 locks was opened (Photo: Rijkswaterstaat)

Third function: fish passage
The Haringvlietdam with its 17 locks was built in the 70's as a sea defence to protect the low parts of the Netherlands against flooding from the North Sea.

The construction of the dam with locks was necessary because it also has to be able – at low tides – to charge the water that flows down the Rhine and Meuse rivers. Therefor the Haringvlietdam has two functions: storm defence and river outlet.

Now a third function has been added: a fish passage. At high tides on the seaside, a small opening allows migration fish to swim into the Haringvliet lake.

Restrictions on salination
However, together with the fish, also salt sea water flows into the fresh water lake. Farmers, industries and water utilities use the lake for the intake of fresh water so the salination of lake is restricted.

Rijkswaterstaat expects that it needs at least three years to optimise the control of the 17 locks for the opening and closing for the three different functions, and optimise the fish migration and at the same time prevent the salination of the lake Haringvliet.

On lake Haringvliet three buoyants with underwater salinity sensors, will measure the salt concentrations at different levels. When the salt levels get to high, the dam will be closed.

The data will be used by Rijkswaterstaat to find an optimum for the optimal operation of the lock for the three functions.

dws-rws-haringvlietdam-sernsor2-350px Bouyant with sensors to measure the salinity of lake Haringvliet 24/7 at three different levels

More fish migration
The use of the Haringvlietdam as a fish passage, is part of a 40-year-old agreement by all riparian states of the Rhine river, to make the river passable from the North Sea all upto Basel in Switzerland by 2020.

Only three barriers still remain and the International Rhine Commission, that has the international coordinates, hopes fish passages will be realized by 2020.

Joint political will
On occasion of the official opening, Mrs. Martine Rohn-Brossard, President of the ICPR underlined: "Such great targets can only be achieved with a joint political will, good cooperation of all states concerned, great efforts of many institutions and parties interested."

"This opening of the Haringvliet dam is a milestone on the way towards sustainably restoring the Rhine and the Meuse", Rohn-Brossard added.

Chipped salmon
Several young Altantic salmon have already been released at various hatches in the upstream in river bed gravels lacking fine sediments and with high oxygen levels. Some of them are known to have made their way to the North Sea and some adult salmon have managed to return to their spawning areas.

The new control of the Haringvlietdam as a fish passage is expected to give this migration a great boost.

In order to know whether it really functions, some salmon will be caught and provided with a chip so that their migration to the spawning grounds can also be monitored.

Export growth Dutch water sector back on track https://www.dutchwatersector.com/news-events/news/35051-export-growth-dutch-water-sector-back-on-track.html dws-wex-2018-ifat-pavilion-770px

Companies in the Dutch water sector report a further growth of their export. For 2018 they expect their exports to be 7.6 billion euro, an increase of 6.9 percent compared to 2017.

Especially companies that are active in the field of water treatment show a continuous growth of their exports. Companies in the field of water management and hydraulic structures faced a period of less export growth that directly resulted from the low oil prices. For 2018, however, they expect a recovery.

The export figures of the Dutch water sector have been published in the latest edition of the Water Sector Export Index (WEX). The latest WEX report gives insight in the definitive figures for 2017, provisional figures for 2018, and a global estimate for exports in 2019. The research was carried out by agency Panteia within the framework of the Partners for Water Programme of the Dutch Government. The Netherlands Water Partnership, Water Alliance and ENVAQUA are the initiators of the research.

dws-nwp-wex2018-graph-350px In 2000 the WEX-index was 100% and ever since the export of the Dutch water sector steadily increased with dips in 2009 (global financial crises) and in 2016 (low oil prices). Source: Water Sector Export Index, December 2018.

Increasing demand
The Dutch water sector is reportedly positive about the future and expects its market share to further expand in 2019.

Increasing demand due to the effects of climate change and urbanisation, is given as main reason for this anticipated growth.

Innovation is key
Managing director Bianca Nijhof of the Netherlands Water Partnership, is happy with these positive expectations and points out that innovation is key to maintain this export growth and compete on the international market.

Nijhof is pleased that the export growth is not only developing in distant countries, but also those closer to home, in Europe. "At NWP we see a lot of possibilities for the Dutch water sector on the European market."

As an example she mentions the initiative of the Dutch water sector at the climate summit COP24 in Poland last December, where Polish and Dutch organisations collaborated on the development of holistic change and concrete actions for ‘climate adaptive cities’ as a first step towards a European Urban Water Partnership.

dws-wex-2018-van-oord-jumana-hopper-utrecht-350px Typical activity for Dutch dredging companies is the rainbowing of sand for land reclamation. Here seen is hopper Utrecht of Van Oord creating Jambalaya Island in Dubai (photo: Van Oord).

Less land reclamations
This especially concerns Dutch companies that export services and equipment related to water management and hydraulic structures (in Dutch referred to as Delta technology), including land reclamation and navigational dredging.

In 2016 this sector segment of the Dutch water sector suffered abroad from reduced investments driven by lower oil prices. Offshore companies and countries in the Middle East, but also Australia and Brazil cut their investments significantly on new water infrastructures.

"These are big foreign markets for Dutch dredging companies such as Boskalis and Van Oord", explains Frank Goossensen, chairman international working group for water and maritime of Topsector Water & Maritiem, a joint trade oriented initiative by the Dutch government and industry.

Coastal cities and river deltas
"Luckily, these companies and also the large consultants anticipated on this development", Goossensen continues, "and are now also focusing on new markets, such as the construction of off shore wind farms and subsea cable laying. These export activities are not reflected in figures of the WEX."

Goossensen expects that Dutch companies will be able to expand their world market position for water-related construction works in coastal cities and river delta areas as a whole. "These activities have the advantage to be less influenced by fluctuating oil prices and are reflecting the global market trends."

Very steady growth
The export figures of companies selling services and products abroad related to water treatment, show a very steady increase and for 2018 another 7 percent growth is expected.

According to managing director Hein Molenkamp of Water Alliance this growth is difficult to explain as the companies are almost all small-medium sized and active in many niches, ranging from processing equipment, sensoring devices, to turn-key delivery of water treatment plants.

Water Alliance is a partnership between companies, knowledge institutes and governments supporting and promoting innovative Dutch water technology companies nationally and internationally and according to Molenkamp this is now beginning to bear fruit. "Most Dutch water tech companies are small or medium sized and we support them in bringing new innovations to the market also export markets", he explains. "An example is the contact we established with five other water tech hubs in the world, Singapore, US, Israel, China and South Korea. Through these contacts we have better access to the local markets."

Leading in many niche markets
But Molenkamp remains modest about the support by Water Alliance. "The export growth is not a consequence of trade missions and collective pavilions at trade fairs only. Somehow the Dutch companies manage to maintain their leading positions in those niche markets."

He specially mentions the entrepreneurship skills, having the right technology and finding good partners abroad. "Apparently they can bring innovations to the market successfully", Molenkamp adds. He is confident that this ability will result in more future export growth for Dutch water technology companies.

About the WEX
The WEX is an indicator that shows the annual exports trends in the Dutch water sector, and specially for the delta and water technology sectors.

The research agency Panteia carried out the research within the framework of the Partners for Water Programme of the Dutch Government. NWP, Water Alliance and ENVAQUA are the initiators of the research.

Dutch-Mexican study: Seagrass beds as an asset for touristic beaches, not only a nuisance https://www.dutchwatersector.com/news-events/news/35045-dutch-mexican-study-seagrass-beds-as-an-asset-for-touristic-beaches-not-only-a-nuisance.html dws-nioz-sea-grass-flow-gully-770pxSeagrass beds are so effective in protecting tropical beaches from erosion, that they can reduce the need for regular, expensive beach nourishments. In a recent article in the journal BioScience, biologists and engineers from The Netherlands and Mexico describe experiments and field observations around the Caribbean Sea. The authors discovered the valuable asset of sea grass for the preservation of touristic coastlines, where sea grass is too often regarded as a nuisance.

Prevention of coastal erosion
According to lead author Rebecca James erosion is a serious problem for Caribbean beaches: "Because of erosion, the economic value of Caribbean beaches literally drains into the sea."

"A foreshore with both healthy seagrass beds as well as calcifying algae, is a resilient and sustainable option in coastal defense", says James, a PhD-candidate at the University of Groningen and the Royal Dutch Institute for Sea Research (NIOZ), the Netherlands.

Expensive engineering efforts
Co-author Rodolfo Silva mentions the negative effects of current coastal development. "The natural flow of water and sand is disrupted, natural ecosystems are damaged, and many tropical beaches have already disappeared into the sea".

dws-nioz-seagrass-erosion-bahamas-350px Coastal erosion at Salvador Island, Bahamas (photo: James St.John/Flickr)

Rodolfo Silva is professor of Coastal Engineering at the Universidad Nacional Autónoma of Mexico. He continues: "Until now, expensive coastal engineering efforts, such as repeated beach nourishments and concrete walls to protect the coast, have been made to combat erosion. Rising sea-level and increasing storms will only increase the loss of these important beaches."

Experimental field flume
To find out to what extent seagrass beds are able to hold sand and sediment on the beach foreshores, James and her team conducted a simple experiment, with a clear result. With a portable and adjustable field flume to regulate water motion in a Caribbean bay, they observed when particles on the sea bed started moving.

"We showed that seagrass beds were extremely effective at holding sediment in place", she says. "Especially in combination with calcifying algae that - create their own sand - a foreshore with healthy seagrass appeared a sustainable way of combating erosion."

More seagrass, less erosion
Along the coastline of the Mexican peninsula of Yucatan, the team put their theory to the test. By looking at beaches with and without protection of healthy seagrass beds, the team discovered that the amount of erosion was strongly linked to the amount of vegetation: more seagrass, meant less erosion.

At beaches where seagrass beds were destroyed, the researchers saw a sudden strong increase in erosion, resulting in an immediate need of expensive beach nourishments.

According to Mark van Koningsveld, professor at the Delft University of Technology and working for the international marine contractor Van Oord, the study opens opportunities for developing new tropical-beach protection schemes, in which ecology is integrated in engineering solutions.

BAM Nuttall begins digging in construction of new Antarctic wharf https://www.dutchwatersector.com/news-events/news/35009-bam-nuttall-begins-digging-in-construction-of-new-antarctic-wharf.html dws-bam-construction-new-antarctic-730pxjpg-1
BAM Nuttall started the construction of a new 74 m long wharf at the Rothera research station on Antarctica, with the excavation work on the deconstruction of the old wharf.

BAM partners with British Antarctic Survey (BAS) to modernise this research facility and all 4,500 tonnes of steel and equipment for the build was recently shipped in from the UK abroard DS Wisconsin.

dws-bam-construction-new-antarctic-ds-wisconsin-off-loading-350px It took 11 days and nights to off load the construction materials that were shipped in from the UK aboard DS Wisconsin. Demolishing of the existing wharf (on top photo) that started last weekend.

Deeper and stronger
The new wharf, bigger, deeper and stronger than the current one, will be built during the next two Antarctic seasons.

It is due for completion in April 2020, and will provide safe berthing and efficient operations for the new polar research vessel the RRS Sir David Attenborough.

First spade in the ground
Whilst preparations for building a new wharf have been underway for two years, the first ‘spade in the ground’ moment occurred last weekend when two 35t excavators - operated by construction partner BAM Nuttall - broke through the surface of the old ‘Biscoe’ wharf.

The excavators will soon be swapped for two 90t long reach machines for the deep excavation and dismantling works.

dws-bam-construction-new-antarctic-ds-wisconsin-ice-350px DS Wisconsin with the construction material making its way through the ice.

Crucial weeks ahead
BAS engineer and project manager David Seaton said: "Construction work in Antarctica is like nothing else, and it has taken a vast amount of planning, practicing and preparation to get us this far."

According to Seaton the next few weeks will be critical to the success of the project. "We hope to make good progress whilst we have long hours of daylight and relatively favourable weather conditions, knowing that in a few months when winter approaches, things are likely to get a lot more difficult."

BAM project manager Martha McGowan said: "The whole team is really pleased to have begun this exciting and important work. It is great to think that the wharf we are building will berth the world’s most famous research ship – the RRS Sir David Attenborough!"

Assembly practised in the UK
Because of the practical restrictions of working in one of the most remote construction sites in the world, the construction team practiced full-scale assembly of the new wharf in Southampton in the UK before deployment.

This made it possible to identify unexpected challenges or additional pieces of equipment needed in the UK, rather than once everything had been shipped 11,000 km to Rothera.

The cargo ship DS Wisconsin, loaded with 4,500 tonnes of steel and equipment for the build, arrived at Rothera on 28th December. Teams worked around the clock to unload her, which took a full 11 days and nights.

Damen to demonstrate InvaSave ballast water treatment system in port Las Palmas, Gran Canaria https://www.dutchwatersector.com/news-events/news/34988-damen-to-demonstrate-invasave-ballast-water-treatment-system-in-port-las-palmas-gran-canaria.html dws-damen-invasave-rotterdam-770pxDamen Green Solutions, part of Damen Shipyards, shipped a container-based InvaSave 300 unit to the port of Las Palmas for the treatment of ballast water from ships that want to change their ballast water.

The shipment is part of Damen’s participation in the European-funded project Atlantic Blue Port Services that involves many ports and research organisations along Europe’s Atlantic coast. The project aims at the introduction of port services for treatment of oil and ballast waters. Part of the project is the demonstration of the InvaSave 300 in Las Palmas.

dws-damen-invasave-port-las-palmas-350px  Port of Las Palmas, Gran Canaria, where the InvaSave 300 will be demonstrated as part of the Atlantic Blue Port project (photo: Port of Las Palmas).

Strict IMO treatment standards
In the port of Las Palmas, the unit will be connected to a vessel’s ballast water manifold to take on the no-longer needed water and treat it to the strict D2-standard as prescribed by the IMO’s Ballast Water Management Convention.

The special part is that the InvaSave is the world’s only land-based ballast water management system that is actually IMO-certified to carry out such a job in a single treatment step, without any holding times or use of chemicals.

Damen Green Solutions Sales Manager Philip Rabe said, "We are delighted to contribute to this important project. The importance of adequate port-reception that facilitates a cleaner maritime industry - is crystal clear and the InvaSave can make important contributions in this regard."

dws-damen-invasave-300-gran-canaria-350px Example of a mobile InvaSave 300 unit as has been shipped to Las Palmas (Photo: Damen).

Workshop session
The demonstration of the InvaSave 300 is part of the 'Atlantic Blue Port Services’ second stakeholder workshop session.

Several interesting presentations are planned besides the demonstration, coming from industry, the Port Authority of the Port of Las Palmas as well as from the Las Palmas University.

The programme itself, a cooperation between close to 30 project partners from Spain, Portugal, France, the UK, Ireland and the Netherlands, intends to promote and develop the feasibility of, and best practices for, port reception and treatment facilities.

The aim is to drastically reduce oil and polluted ballast water discharge at sea.

Alu Circles initiative to stimulate water utilities for more recovery of aluminium from drinking water sludge https://www.dutchwatersector.com/news-events/news/34966-alu-circles-initiative-to-stimulate-water-utilities-for-more-recovery-of-aluminium-from-drinking-water-sludge.html dws-allied-water-drinking-water-sludge-700px
Allied Waters and Corvers launched the Alu Circles initiative that aims to increase the recovery of aluminium from residuals from drinking water production. The initiative builds on the promotion by the European Union of pre-commercial procurement (PCP) as a tool for the public sector to create business cases for recovery of valuable materials. By stimulating innovation procurement water utilities can offer sludge to the recovery market at lower costs compared to the disposal to the traditional sludge treatment market.

Water cycle game-changer company Allied Waters and Corvers Procurement Services announced their Alu Circles initiative on 13 December.

dws-allied-waters-dry-sludge-oasen-350px  Drinking water treatment sludge can be turned into valuable materials as here seen by Dutch water supply company Oasen (Photo: Oasen).

Involvement whole chain
Allied Waters and Corvers want to achieve this by involving technology providers, water suppliers and researchers in a multi-stage process.

The tool of pre-commercial procurement (PCP) is very useful as it provides water utilities, as public procurers, the possibility to include specifications in their sludge disposal contracts, that aim for the upcycling.

Cost reduction
The Alu Circle initiative wants to develop a new value chain for the upcycling of aluminium sludge and achieving a cost reduction for the water utilities of more than 30 percent.

Drinking water plants generally use aluminium based flocculants for the treatment of surface water. This produces sludge that is typically sent to a disposal site as it has few beneficial uses.

According to Allied Waters and Corvers these disposal costs often exceeds 100 euro per ton sludge.

For a water plant producing 100 million m3 drinking water per year, this represents a cost of around 100.000 euro annually.

The challenge is to convert this one-off use of material into a sustainable solution, such as upcycling or recycling, at lower cost. This is the principal goal of Alu Circles.
Scheme of how a pre-commercial procurement can help to turn costly waste disposal into recovery of valuable products.

Open for participation
The initiative is open for water utilities, that can join as a member of the core team and be involved in the project strategy and related activities. Two organisations that have already stepped in on that level, are AquaMinerals (NL) and De Watergroep (BE). It is also possible to join the initiative as a participant to receive project results and gain infomation on new value chains developed.

The initiative has planned a webinar to inform interested parties how to become involved in the recovery of aluminium from drinking water sludge.

The webinar is scheduled for Wednesday 23 January 2019, 12.00 h (CET).

The 4,200m³ TSHD was partly built at IHC shipyard in The Netherlands and has been completed in Montevideo.

dws-ihc-dredger-de-julio-on-trial-350px Uruguay dredger 21 De Julio on sea trails,

Basic design
The basic design and detailed engineering of the vessel was supplied by the IHC headquarters in the Netherlands as well as the highly complex dredging parts and equipment.

IHC signed the contract for the design, construction and delivery of the TSHD with ANP in November 2016, and the keel laying ceremony took place in October 2017, simultaneously in both countries.

After finishing the keel and stern of the dredger in the Netherlands, these parts were transported to Uruguay in May 2018, where the rest of the TSHD was built for Administración Nacional de Puertos (ANP).

The cooperation between IHC and ANP dates back to the 1970s, with the delivery of TSHD Draga D-7, which remains part of ANP’s fleet.

dws-ihc-dredger-de-julio-two-parts-350px Arrival of the keel and stern in Montevideo in May 2018.

Local for local
Traditionally, IHC has built dredgers at its shipyards in the Netherlands and it still does so, but, since the 1970s, it has built dredgers in other countries. 

By 2000, it was building more dredgers abroad than at home, based on the ‘local for local’ principle, meaning that dredgers were built in a client’s home country. 

So in China and Brazil, for example, a large number of Beaver cutter suction dredgers have been buit for local clients.

Another example is the larger 12,000 m³ TSHD Chang Jiang Kou 02, which was built in China in 2012 for the Yangtze Estuary Waterway Administration Bureau (YEWAB).

Comparative pilot effluent polishing with UV and ozone at wwtp Aarle-Rixtel, the Netherlands https://www.dutchwatersector.com/news-events/news/34910-comparative-pilot-effluent-polishing-with-uv-and-ozone-at-wwtp-aarle-rixtel-the-netherlands.html dws-nijhuis-remmen-wwtp-aarle-rixtel-container-yellow-purple-770px-1Dutch Minister Cora van Nieuwenhuizen kicked off a pilot at municipal waste water treatment plant (wwtp) Aarle-Rixtel, the Netherlands, on 17 December for the comparison of the additional effluent-treatment with ozone filtration and UV-filtration. The pilot is meant to get more insights in the performances of both water treatment technologies on the removal of medicine residues. 

Waste water treatment plant Aarle-Rixtel is operated by regional water authority Aa en Maas, that considers an additional treatment step to increase the overall removal of medicine residues from the current 60 percent to 80 percent.

The pilot is part of an overall Dutch national programme to prevent medicine residues ending up in surface water.

dws-nijhuis-remmen-nieuwenhuizen-verheijen-350px  Official start of the comparative Ozone-UV pilot study by Dutch minister Cora van Nieuwenhujizen (left) and dijkgraaf Lambert Verheijen of the regional water authority Aa en Maas.

Two containers, two technologies
For one month a small part of the wwtp-effluent will be treated simultaneously in two separate containers. One container (in purple on top photo) houses the latest version of the UV-C light and hydrogen peroxide effluent (AOP) treatment technology Advanox by Van Remmen. The other container (in yellow) houses the latest version of an Ozone bioreactor by Nijhuis Industries.

Without further intervention by its suppliers, the two containers will treat the effluent for four weeks.

The aim of this test is to provide regional water authority Aa en Maas a better insight in the removal of the individual substances of the medicine residue, the energy consumption, the formation of by-products and the costs.

dws-nijhuis-remmen-mbr-ozon350px Nijhuis industries uses Bioctor-MBBR technology for the removal of the decomposed pharmaceutical residues.

Ozone versus UV
"Both treatment technologies have their disadvantages", commented Policy advisor Maarten Nederlof of Aa en Maas at the start of the pilot.

"It is possible to remove more medicine residue but that goes at the expense of an increased bromate concentration in case of ozone oxidation, and more energy consumption in case of UV-H2O2."

Nederlof hopes the pilot will reveal the optimum dosing of UV-light and ozone in relation to the removal of the remaining medicine residue in the wwtp-effluent.

Application of activated carbon
Last year, the activated-carbon technoogy, has already proven to be efficient at a pilot test at wwtp Papendrecht, the Netherlands. Here powered activated carbon was added to the sludge in the aeration tanks. This resulted in a good removal of the medicine residues, and a decreased toxicity of the effluent. However, the residues are not destroyed, only shifted from water to solid waste.

The dosing of powered activated-carbon in the aeration tanks may influence the removal of nutrients, so it may be necessary to adjust the wwtp first.

Outlook 2019: What trends will shape the global water sector this year? https://www.dutchwatersector.com/news-events/news/34878-outlook-2019-what-trends-will-shape-the-global-water-sector-this-year.html dws-outlook-2019-poster-770px(editorial by Jac van Tuijn) 
A new year ahead, full of new setbacks and opportunities. Let's make the best of it. Personal and professional.

Some seek opportunities for a nation, for a company or for their own. Others seek global cooperation for the benefit of all. Are these two sides of the same coin, called globalisation? It will be interesting to see the gains and losses in 2019 for those who built walls and those who break them down. How will the process of globalisation further develop in 2019? Traditionally, it has always been led by global trade, but today’s globalisation is increasingly led by the personalisation of modern society with its digital technology.

Let’s embrace the opportunities of modern globalisation and its technology, but keep our eyes open for local concerns and curve the negative effects on marginalised people. Leaving no one behind is this year’s theme of World Water Day on 22 March.

dws-outlook-2019-wwd-theme-poster-350px  This year's theme of World Water Day is 'Leaving no one behind' and addresses the minority groups that lack access to clean water and toilets.

Global versus local
Local unrecognised concerns are often related to problems with too little, too much or too polluted water. These relations make local water problems complex and difficult to solve.

Last year the United Nations reported on the progress of the Sustainable Development Goal 6 on water and concluded it is ‘off track’. And this not only concerns the need for more visible water infrastructure such as taps, toilets, pipes and treatment plants. But the report also mentions the invisible needs, such as the protection of fresh water resources from overexploitation and the effective sharing of limited water resources among competing demands.

Polder tables
In this regard, the concept of ‘polder tables’ may pop up in 2019. For centuries Dutch regional water authorities built on the concept of ‘poldering’, that it has now become a renown national governmental tradition of consensus decision-making by parties with competing demands.

The latest version of this Dutch governance concept for complex issues is the ‘poldering tables’. In practice, this means that representatives of groups with different interests discuss solutions with the biggest potential. Each group has a specific aspect of a complex issue and – supported by experts - discuss which solutions suits best.

This year we will certainly hear more of this 'poldering' concept as the Water as Leverage programme enters its second phase in the Asian cities of Chennai, Semarang and Khulna. And also on World Water Day when the Dutch water authorities will announce their first projects of the Blue Deal programme - forging partnerships on integrated water resource management in 20 catchments in the world.

dws-outlook-2019-water-as-leverage-chennai-350px 'Polder tables' are no ordinary discussion tables at conferences, but concern the solving of real water issues with a consensus by all parties involved. Here seen is a 'polder table' in Chennai, India as part of the Water as leverage programme.

Water-energy efficient cities
Cities will continue to grow, controlled and uncontrolled. Mayors will seek new ways to manage this growth and keep their cities liveable. Cities in older economies urgently need to replace their aging water infrastructure. However, many cities lack funds so the use of smart asset management will become more popular.

Better monitoring, combined with artificial intelligence, provides the opportunity for location specific repairs and extend the life of pipeline systems and treatment plants.

In their contribution to the Paris climate agreement, many cities made ambitious plans to become carbon neutral and energy efficient. The new kid on the block is heat recovery from water systems. Direct heat recovery is possible from warm domestic waste water. Indirect heat recovery is possible from urban surface water that heat up during the summer and stored in the underground, to be extracted in the winter.

The realisation of these ambitious city climate plans will undoubtedly impact the development of urban water systems. That will also incorporate more use of storm water and waste water effluent where water demands exceed the availability from fresh water sources situated close to the cities.

Leaving no one behind
But cities also grow uncontrolled. Take the 700.00 Rohingya refugees that live in Kutupalong, Bangladesh. In one-and-a-half year, 27 refugees camps grew together and now form one big city of makeshift tents and shacks.

Efforts to provide enough safe drinking water for refugees across all the heavily congested sites has been a massive challenge for humanitarian agencies, requiring the drilling of thousands of deep tube wells and building water networks including the installation of pipes, dams, canals, filtering mechanisms and chlorination systems.

Leaving no one behind not only applies to the Rohingya refugees, but also for disabled, suppressed minority groups and the poorest 10 percent of the world.

dws-outlook-2019-joint-solutions-350pxLeadership and coalitions
Two international water events that will take place in The Netherlands will stand out for their leadership. On the occasion of its 50th anniversary, the think-and-do tank IRC Wash, organises an international conference on water systems in March. IRC wants decision makers from all other the world to come together and think about improvement of water services as whole, not just a tap or a toilet. As a reality for everyone forever, not just a project for a few.

The other leading international water event in The Netherlands this year will be the 5th edition of the Amsterdam International Water Week in November. Highlights will be the international AIWW Conference and the Aquatech Amsterdam trade fair on water technology.

Global leaders of water utilities, cities and industries will again join the Leader Forums and discuss the progress and new development following the 2017-edition.

Something to look forward to will be the progress reports on the Amsterdam Agreements. Several coalitions of companies, institutes and authorities in the water sector have entered on real case projects to achieve breakthroughs on water issues.

The coalitions will show case their projects and share their latest knowledge and experiences. Hence contributing to the achievement of the UN Sustainable Development Goals in general, and SDG 6 on water in particular.

The Dutch water sector realises that water does not stop at borders and invites everybody to team up in 2019 for the development of long term solutions.

Global water challenges… joint solutions. Let’s work together!

Ocean Cleanup reports on second set back: End section breaks off https://www.dutchwatersector.com/news-events/news/34865-ocean-cleanup-reports-on-second-set-back-end-section-breaks-off.html dws-ocean-cleanup-two-setbacks-770pxThe Ocean Cleanup reported the break-off of a 60 m long end section of its floating plastic collection system operational in the Great Pacific. The fracture has been noticed during a regular inspection on 29 December, and it is hypothesized to have been caused by material fatigue.

Both the 580-meter main section and the 18-meter end section remained completely stable, but the team of Boyan Slat decided to return the whole system earlier to port to repair and upgrade it, than planned.

dws-ocean-clean-up-closing-lines-350px  The team tested and evaluated the effects of widening of the U-shape by extending the closing line.

Second set back
It was the second set back reported by the team in short notice. Late November the team reported the first collection of plastic garbage but that it occasionally also drifts out.

The team used GPS-drifters and drones to collect data on the behaviour of the floating system and the plastic garbage. The data is now analysed on why and when the plastic floats out again.

This information will be used to upgrade the world’s first operational system for collecting floating plastic, for instance by increasing the span of the U-shape. This changes the force balance so the impact of the wind increases.

All bulkheads intact
Because of the early detection of the break-off, no material was lost and there have been no safety risks for the crew, environment or passing marine traffic.

All bulkheads are reportedly intact, and the end section has two stabilizers affixed to it, so rollover is not possible.

The fact that the cleanup system orients itself in the wind, is able to follow the waves well and is able to catch and concentrate plastic gives the team confidence in the technology.

The team expects to be back in operation later in 2019.

Coastar: Fighting drought by capturing meltwater from mountains in Chile https://www.dutchwatersector.com/news-events/news/34761-coastar-fighting-drought-by-capturing-meltwater-from-mountains-in-chile.html dws-coastar-rio-elqui-770pxCoaster-consortium partners consisting of consultancy firm Arcadis and research institutes KWR and Deltares, got green light to start a groundwater catchment project in the basin of the Elqui river. The three partners use the Coastal Aquifer Storage And Recovery (Coastar) concept to create a robust underground water storage to bridge the gap between water supply and water demand in time and space. The project will start in April 2019 and will be implemented in 2020.

Over extraction of groundwater
Certain regions in Chile are characterised as dry areas, partly because Chile currently takes too much groundwater in some places.

In order to cope with the growing demand for freshwater for agriculture, industry and households, new fresh water sources are being investigated besides water from rivers and lakes.

The depletion of the ground - and surface water resources without providing for the maintenance and expansion of these sources will eventually lead to shortages and possible salinisation of the water.

Subsurface catchment
The concept of Coastar has specially been developed for large scale subsurface catchment of fresh water such as the meltwater from the mountains, which is normally discharged via the rivers into the sea.

"During this project, we will investigate how we can optimise this mechanism", explained Esther van Baaren, on behalf of Deltares. "By infiltration of the water, the groundwater supplies are replenished so they can recover over time. The groundwater reservoir thus remains in use for example, for irrigation of the olive groves", Van Baaren added.

The consortium cooperates with Van Essen, Fugro, Hellema and regional partners such as Corporación de Desarrollo Productivo, Rabo Chile, Junta de Vigilancia Rio Elqui y sus Afluentes, Region de Comquimbo and the University of La Serena.
