AIWW conference: Showing leadership in finding solutions to address water and 9 billion people https://www.dutchwatersector.com/news-events/news/25487-aiww-conference-showing-leadership-in-finding-solutions-to-address-water-and-9-billion-people.html dws-aiww-leadership-poster2-770pxThe organizers of the next edition of the Amsterdam International Water Week conference have set themselves an ambitious goal and invite everybody to come to Amsterdam and show leadership on the issue of sustainable water use for 9 billion people by 2050.

“It means we have to change our policies, we have to look to reuse of water, we have to look to create a circular economy,” said Roelof Kruize, CEO of Waternet, the Amsterdam water utility, and a member of the managing board of Amsterdam International Water Week.

The 4th edition of the Amsterdam International Water Week (AIWW) will take place from 30 October till 3 November. AIWW’s main events are the international AIWW conference, the Aquatech trade fair on water technology and the Floodex trade fair on flood control.

dws-aiww-leadership-kruize-350px  CEO Roelof Kruize of Waternet, the Amsterdam water utility.

Crucial global issue
The title of the next edition of the Amsterdam International Water Week conference appears simple, but it captures the scale of the challenge around what is one of the crucial global issues: ‘Water… and 9 billion people’.

The use of the projected global population for 2050 underlines the need for new approaches.

Urban populations are set to swell further, so Kruize points to other types of action–making cities rainproof, and adapting to climate change. “This ‘9 billion people’ is very important for the topics we want to show and discuss at the AIWW,” he added.

Solve real cases
“We aim to form coalitions to help solve certain cases and certain themes” said Kruize. “That’s quite unique, I think,”.

The goal of AIWW is to provide visitors with answers to the questions they face in their working lives. Kruize will be looking for exactly this himself.

“As CEO of Waternet, I am hoping to get some new ideas on the questions I am busy with every day.” He encourages those working in water utilities, cities and industry to come in search of their own answers, and notes that there is already commitment for high-level participation from around the world. “The response we have had so far makes me very enthusiastic,” he said.

dws-aiww-leadership-drilling-350px There's always something happening at AIWW, such as the drilling & tapping championships.

Other highlights:
● key note
Mayor Ahmed Aboutaleb of Rotterdam will deliver the key note, explaining how his city takes the lead in the worldwide C40-network and pioneers on climate adaptation and urban water issues

Sweden’s first Nereda wastewater treatment plant to be built in Strömstad https://www.dutchwatersector.com/news-events/news/25457-sweden-s-first-nereda-wastewater-treatment-plant-to-be-built-in-stromstad.html dws-rhdhv-nereda-wwtp-stromstad-aerial-770px
In a first for wastewater treatment in Sweden, Royal HaskoningDHV’s Nereda technology has been selected as the preferred solution for a new wastewater treatment plant in Strömstad.

The construction phase of the project has started with the plant scheduled to be ready by June 2018.

Econet Vatten & Miljöteknik has been appointed by the municipality of Strömstad to deliver and install all the mechanical equipment.

dws-rhdhv-nereda-wwtp-dinxperlo-350px  Nereda plant at wwtp Dinxperlo, the Netherlands.

Without chemicals
Jerry Johansson of the municipality of Strömstad, responsible for the wastewater plant said: ”We needed to increase the capacity of its wastewater treatment works while reducing the operational costs and the energy consumption.

Johansson continued: “Several different types of wastewater treatment technology were considered before being rejected in favour of Nereda, which is a natural sewage treatment process that purifies water without chemicals by using the patented aerobic granular sludge technology.”

Enormous population swells
Located close to the Norwegian border, Strömstad is an increasingly popular holiday destination for tourists and the town’s population swells enormously during the summer months, more than doubling the number of residents.

As a result, the municipality knew that the new plant would need to be able to cope with widely varying volumes of wastewater. The plant also has to remain efficient during very cold conditions in the Swedish winter.

Furthermore, Strömstad was seeking the most competitively priced solution in terms of operational costs over its lifetime, as well as its initial construction.

dws-rhdhv-nereda-wwtp-stromstad-riky350px Aerial view of Nereda plant at wwtp Riky, Poland.

Cold winters
Project Manager Bert Bakker of Royal HaskoningDHV commented: “This technology has been tried and tested all over the world, from hot and arid conditions in South Africa to very cold winters in Poland.”

“So we knew that low temperatures in Sweden would not present a problem”, Bakker added.

“It also can easily adapt between high and low volumes of wastewater. When it comes to long term running costs, Nereda is so efficient, particularly in terms of energy consumption, that it was by far the most competitive solution.”

A4Lab deploys drones to explore water potential of dry river beds in Mozambique https://www.dutchwatersector.com/news-events/news/25419-a4lab-deploys-drones-to-explore-water-potential-of-dry-river-beds-in-mozambique.html dws-ihe-a4labs-dry-river-bed-770pxResearch group A4Lab deployed a drone of Mozambique-based company ThirdEye, to assess the water availability in the dry river beds of the Limpopo river, near the city of Chókwè in Moazambique.

The exploration is to deliver more data on the amounts of water in the sandy river beds throughout the dry season with the potential for intensifying irrigated agriculture.

The aerial exploration was carried out by the A4Lab Mozambique partners, including local authorities of Quijá District, the NGOs Oxfam Mozambique, ADCR and Kulima, the Institute Superior Politécnica de Gaza - together with Tibor Stigter and Pieter van der Zaag of IHE Delft, The Netherlands.

dws-ihe-a4lab-third-eye-drone-350px One of the drones operated by ThirdEye for the collection of aerial images and data for some 4,000 small farmers near Xai-Xai and Chókwè, Mozambique.

Underutilised water resources
One key to unlocking Sub-Sahara Africa’s agricultural potential is enhancing water security by means of increased capacity to store water.

The river beds of seasonal rivers provide such opportunities. The numerous seasonal rivers and streams in these areas form a natural buffer when water infiltrates in alluvial river channels and adjacent river banks during the rainy season.

Communities use the water during the dry season by scoop holes, hand pumps, dug wells or other simple abstraction means. These aquifers have a distributed storage potential that is currently under-utilised.

Water storage in these rivers is mostly unmanaged.

dws-ihe-a4lab-sand-dam2-350px Many African rivers run dry but there is a big potential to store more water by building small masonry (sand) dams.

Three living labs
As these alluvial aquifers are not yet recognized as an opportunity for local farming, the research programme Arid African Alluvial Aquifers Labs Securing Water for Development (A4 Labs) was launched last year.

The programme aims to develop new methods for farmers to use water underlying dry river beds and use shallow groundwater more efficiently and sustainable.

Three experimental sites - living labs – have been established for smallholder farmers, practitioners, agricultural extension officers, water engineers, private sector and students, to develop such new methods.

The A4lab sites are situated in three arid to semi-arid regions in Africa:
● Tekeze, Tigray region, Ethiopia, Nile basin
● Mzingwane, Mtabeleland, Zimbabwe, Limpopo basin
● Limpopo, Gaza Province, Mozambique

More crop per drop
One of the research topics is to better understand the functioning of the hydrological system. For a sustainable use it is essential to measure water levels and rainfall on a continuous basis.

The field labs have initiated to collection of such data that will be sent through a telemetric system, so that it can be showed live online.

New Dutch professor coastal engineering: Be prepared for mega beach nourishments https://www.dutchwatersector.com/news-events/news/25381-new-dutch-professor-coastal-engineering-be-prepared-for-mega-beach-nourishments.html dws-tud-aarninkhof-address4-770pxBased on the latest studies on melting sheets, the Dutch government should better prepare for a sharp increase of beach nourishments, advised new coastal engineering professor at the Delft University of Technology, Stefan Aarninkhof, in his inaugural address on 10 May.

Aarninkhof questioned whether the current nourishment strategy for the Dutch coastline, is fit for the future when sea level rise will force a sharply increase of the volume of sand supplements. He plead for a study on the efficiency of mega coastal sand supplements.

Professor Aarninkhof succeeded Marcel Stive at the Coastal engineering faculty last year.

dws-tud-aarninkhof-portret-350px  Professor Stefan Aarninkhof succeeded Marcel Stive at the Coastal engineering faculty, of the Delft University of Technology.

Coastal flood defence
The Dutch coast is largely erosive and a retreat of the coastline endangers the strength of the dunes as a sea-defence. In order to defend the low-lying hinterland, it is essential for the Dutch flood control to keep the coastline in place.

Therefore the Dutch national public works, Rijkswaterstaat, annually nourishes the Dutch coast with 12 million cubic meters of sand. These supplements aim to maintain the coastline of 1992.

Quicker rate
According to Aarninkhof it may be necessary to increase this volume drastically as the latest studies on the melting of polar ice indicate a faster rise of the sea level.

Aarninkhof noted that many recent studies indicate a faster ice melting. He advised The Netherlands to look into more dramatic climate change scenarios more closely to be able to increase the beach nourishments at a much quicker rate.

Mega nourishments
Rijkswaterstaat gained much efficiency in the past by supplementing the sand on the fore shore, rather than on the beach itself. In line with such an innovation of beach nourishment, Aarninkhof mentioned the mega nourishment 'the Sand Motor'. In 2005 20 million cubic meter of sand was placed on the foreshore of the coast of The Hague during one mega nourishment.

Natural elements, such as wind, tide and currents, are now displacing this sand along the coast, strengthening the coastline as a flood defence.

dws-tud-aarninkhof-stive-350px In his farewell address emeritus professor Marcel Stive mentioned the successfull fixation of the Dutch coastline and the development of the Sand Motor of which he was one of the initiators.

New strategy
“We need to look at long-term financing of such mega nourishments”, Aarninkhof continued in his inaugural address. He called for more efficiency by looking at the coastline as a whole, rather than as many small sections.

“Mega nourishment of 20 million cubic meter of sand for 20 years is no cheaper than four regular nourishments of 5 million. This may be different if a strategy foresees in a series of mega nourishments. Especially if sea level rise will force us to supplement much more sand”.

Such a long term strategy may interest private parties to join such mega nourishments for reasons of nature or coastal development. It is possible to adjust the design of such mega nourishment accordingly, said Aarninkhof.

Coastal observatory
Finally, he pleaded for the establishment of a Coastal Observatory along the Dutch coast.

Such a Dutch observatory can be part of the newly established international network International Coastline Observatories Network (ICON), Aarninkhof suggested.

New approach to stabilize river discharges involves local population in Indonesia https://www.dutchwatersector.com/news-events/news/25363-new-approach-to-stabilize-river-discharges-involves-local-population-in-indonesia.html dws-wur-stable-river-indonesia-flood-770px-1Scientists from the World Agroforestry Centre in Indonesia and Wageningen University & Research have developed an approach in Indonesia which stimulates the local population to buffer the drainage in catchment areas of strongly fluctuating rivers.

The approach involves using a new and relatively easy to determine property of the river to calculate remuneration for the local population for their active contribution to achieving a more stable discharge from the catchment area, making the area ‘healthier’.

dws-wur-stable-river-map-se-asia-350px   Map of South-East Asia showing three river basins in relation to their agroecological zones, ranging from dry (orange), humid (green) to water tower (blue).

Soil related buffering
In catchment areas where the land offers little buffering (sponge effect), heavy rainfall has a direct and severe impact on the amount of rainfall that gets into the river within a day– with all the consequences thereof.

The river discharge is much more gradual in catchment areas where the soils can absorb and retain lots of water, a far more desirable situation not least because of the way it reduces the risk of flooding.

Buffering management
Until now there was no proper but simple way of measuring the capacity of a catchment area to buffer rainwater.

While the amount of forest present in an area is a commonly used measurement for the buffering function, it raises questions as to what happens outside the forest and what does or does not count as forest.

dws-wur-stable-river-noordwijk2-350px Meine van Noordwijk, chief science advisor for the World Agroforestry Centre and special professor of agroforestry at Wageningen University.

Slow positive effect
According to Meine van Noordwijk, professor in agroforestry at Wageningen University & Research, these forests are a good example of the complexity of water buffering management.

“Deforestation can indeed lead to reduced buffering”, Van Noordwijk continues. Reforestation can improve the situation and mitigate floods and droughts".

“However, once the soil has compacted to such an extent that it cannot easily absorb water due to deforestation”, he warns.

“Any reforestation of the area has only a very slow positive effect on the buffering of rainwater over a period of some ten to twenty years.”

Electromagnetic ‘cigar’ maps fresh, brackish and saline groundwater in Zeeland, the Netherlands https://www.dutchwatersector.com/news-events/news/25341-electromagnetic-cigar-maps-fresh-brackish-and-saline-groundwater-in-zeeland-the-netherlands.html dws-freshem-sensor-helicopter-zeeland-airport-770pxThe Dutch Province of Zeeland has published an online map showing the presence of fresh, brackish and saline groundwater. The data has been collected with an electromagnetic ‘cigar’ hanging underneath a helicopter.

The map shows the volumes, depths and locations of fresh groundwater, providing important data for local farmers and water authorities.

The publication is part of the research project Fresh salt groundwater distribution by helicopter electromagnetic survey (Freshem), run by research institutes Deltares (Netherlands), TNO (Netherlands) and Bundesanstalt für Geowissenschaften und Rohstoffe (Germany).

dws-freshem-map-zeeland-350px  Depth of salt groundwater (1.500 mg/l) in the province of Zeeland. In red (less than 2.5 m), in yellow (10 m) and in blue (more than 40 m).

Usable groundwater data
Together with TNO and BGR, Deltares developed the method for converting electromagnetic measurements into useable data.

“By combining saltwater-freshwater data with a broader knowledge of groundwater systems, we can make predictions about climate change and sea-level rise”, says Deltares-researcher Esther van Baaren.

“As a result, we are able to make predictions about the availability of fresh groundwater in the future”, van Baaren continues.

Helicopter-borne measuring
A helicopter of the Bundesanstalt für Geowissenschaften und Rohstoffe flew over the province many times, carrying electromagnetic transmitters and receivers that are housed by a tube, the bird.

This bird is towed by a 45 m long cable about 30-40 m above ground.

By transmitting dipole signals the bird can determine boundaries of fresh and salt groundwater up to a depth of 100 m.

dws-freshem-helicopter-sensor-aerial-350px Helicopter and sensor of German research institute BGR.

Imbalanced availability
Many areas of the province of Zeeland have few options for supplying their own fresh water for domestic and agricultural use. Over the year as a whole, there is more precipitation than evaporation but the situation is reversed in the summer, when there is simply not enough water available.

This imbalance is being exacerbate by climate change. “In the long run, that will cause problems for the availability of fresh water in Zeeland”, predicts Ben de Reu, Deputy Water of the Province of Zeeland. “That is why the province stimulates a number of initiatives for storage of and more efficient use of fresh water”.

The fresh-saline mapping also helps farmers in Zeeland to store fresh water underground when rainfall is plenty in locations that have been identified as promising by the measurements.

Farmers and nature managers now know where the subsurface is saline and how saline it is exactly.

Worldwide fresh water hunt
This month a similar project will start in Belgium on behalf of the Vlaamse Milieumaatschappij within the European project Topsoil. The aim is to identify promising agricultural sites for the underground storage of fresh water.

In the hunt for scarce fresh water, Deltares is using similar technology to map the fresh-brackish-salt distribution in the Vietnamese subsurface. A WalkTEM survey learned that the distribution is extremely heterogeneous: at large depths down to at least 200 metres, fresh groundwater can be found next to salt water.

Deltares works together with NWO, Utrecht University, the Danish Aarhus University, TNO en The Vietnamese Division for Water Resources Planning and Investigation for the South of Vietnam.

The groundwater salinity maps of the Province of Zeeland are available online at www.zeeland.nl (in Dutch only).

IRC supports full WASH coverage start-up initiative in Kenyasi, Ghana https://www.dutchwatersector.com/news-events/news/25321-irc-supports-full-wash-coverage-start-up-initiative-in-kenyasi-ghana.html dws-irc-ghana-wash-770px-1Dutch-based non-profit organisation IRC Wash, together with Safe Water Network and Asutifi North District Assembly, launched the District Based Full WASH Coverage start-up initiative in Kenyasi, Ghana.

This initiative will support the design of a master plan for achieving universal coverage, to create a blueprint for districts to reach full coverage of water supply and sanitation facilities within the next 15 years.

The initiative was quick started at an inception workshop held on March 16 and is supported by the Conrad N. Hilton Foundation. 

This has been reported by Jeremiah Atengdem, water expert at IRC Ghana.

dws-irc-ghana-workshop1-350px Director of IRC Ghana, Vida Duti, at the workshop.

Full WASH coverage by 2025
Ghana is committed to the attainment of Sustainable Development Goal (SDG) 6 for ensuring sustainable management of water and sanitation services for all by 2030.

Consistent with this goal, the WASH sector in Ghana aspires to reach full coverage by 2025. Within the rural and small town sub-sector in Ghana, progress has been made in extending rural and small town coverage from 29 percent in the 1990s to 65 percent in 2015 with very slow growth registered in sanitation coverage which stands at about 15 percent (in 2015).

Challenges ranging from lack of finances to poor sector coordination within the local decentralised system hamper progress and the achievement of set targets by 2025.

dws-irc-ghana-workshop2-350pxOn district level
Contributing to this target, the District Based Full WASH Coverage initiative wants to ensure every citizen of the district in the Asutifi North district has access to water and sanitation services.

The partners also hope to use this initiative to demonstrate that it is possible to achieve full coverage in sustainable rural water and sanitation services within a district. Positive results will be shared across Africa and the world at large for possible replication.

Economic transition
Asutifi North faces the typical challenge of rapid urbanisation and agglomeration due to economic pulls. It presents a growing local economy moving from subsistence agriculture to mining, commerce and services and small-scale process.

The transition in all respects presents opportunities and these must be nurtured, enhanced and facilitated to support the effective change and delivery of WASH.

The twin-hulled, 382 m long and 124 m wide vessel just returned from lifting the top side of Shell’s Brent Delta platform in the North Sea and transporting it to a British scrapyard.

The vessel’s new job in the Black Sea consists of the installation of two, 900 km long pipelines on the seabed in water depth of 2.200 m.

dws-alleseas-pioneering-spirit-stinger-325px  The 150 m stinger that leads the gas pipes to the bottom of the sea

Stinger
For the job, the Pioneering Spirit has been equipped with a 150 m long Stinger, a frame that hangs behind the Pioneering Spirit.

On board of the Pioneering Spirit, pipe parts are welded together. Via a transition-frame the pipe is placed on the Stinger and rolls over the 'rollerboxes' into the water.

The Stinger leads the pipe to the bottom of the sea and guarantees the most ideal curvature of the welded pipe during the installation phase.

Gas pipeline
In December 2016, Allseas was awarded a contract to lay the first line of the TurkStream offshore gas pipeline in the Black Sea, with an option for laying the second line.

Allseas already started the pipelaying work with its Audacia vessel. Construction work for the pipeline in deepwater area will be performed by the Pioneering Spirit.

The offshore pipeline will consist of four parallel pipelines running through the Black Sea. The pipelines will enter the water near Anapa, on the Russian coast, and come ashore on the Turkish coast some 100 km west of Istanbul.

The foundation will use a new developed technology based on floating anchors, instead of the initially planned fixed anchors.

The increased efficiency of the system, allows for the cleanup of half the Great Pacific Garbage Patch in just 5 years.

Reportedly, parts of its cleanup system are already in production.

dws-ocean-cleanup-next-phase-floating-anchor-350px  Series of floating anchors (two black structures) are to keep the screen (black line below) in place.

Floating screens
The main idea behind The Ocean Cleanup is to let the ocean currents do the work. An installation of U-shaped screens channels floating plastic to a central point. The concentrated plastic can then be extracted and shipped to shore for recycling into durable products.

The improvements announced involve the introduction of a mobile, or drifting system. Rather than fixing the floating screens to the seabed at great depths, floating sea anchors will be used to ensure the also floating screens move slower than the plastic.

Rather than one massive barrier, the improved, modular cleanup system consists of a fleet of individual, smaller seized screens.

First tests
This new, modular technology and the successful funding round announced on May 3, 2017, enable The Ocean Cleanup to accelerate production, deployment and the actual extraction of plastic from the ocean. Testing of the first system will start off the American west coast by the end of 2017.

With the first deployment in the Great Pacific Garbage Patch in the first half of 2018, The Ocean Cleanup will start its mission two years ahead of schedule.

In front of a live audience of thousands of its supporters, and a large group of followers on-line, The Ocean Cleanup shared details on the improved design, and announced the start of the cleanup.

Still experimental
On the occasion, founder and CEO Boyan Slat of The Ocean Cleanup demonstrated the new technology and unveiled the first parts of the cleanup system: four 12-meter (40-foot) high anchor components (see on top photo).

Boyan Slat commented: “At The Ocean Cleanup we are always looking for ways to make the cleanup faster, better and cheaper. Today is another important day in moving in that direction. The cleanup of the world’s oceans is just around the corner.”

He added that the large-scale trials of its cleanup technology in the Pacific Ocean later this year are still experimental in nature. "Due to our attitude of ‘testing to learn’ until the technology is proven, I am confident that – with our expert partners - we will succeed in our mission."

Royal HaskoningDHV to improve use of rain radar data for better water-related weather forecast https://www.dutchwatersector.com/news-events/news/25233-royal-haskoningdhv-to-improve-use-of-rain-radar-data-for-better-water-related-weather-forecast.html dws-rhdhv-rain-radar-rotterdam-770px
A special team led by Dutch-based consultancy firm Royal HaskoningDHV, has been assigned by local municipal and provincial authorities to translate the data collected by a rain radar in Rotterdam into a more accurate forecasting for end users, such as operators of pumping stations and rain water drainage systems.

The dual-polarization X-band radar was installed on the roof of a sky scraper in the city centre of Rotterdam in 2015 as part of an EU-funded project, RainGain (see on top photo).

Delft university of technology and ICT-firm SkyEcho are currently developing specific software to transform the radar signals into rainfall. New instruments and software will be tested during an intensive monitoring campaign in the Rotterdam region this summer.

dws-rhdhv-rain-radar-map-350px  Detailled mapping of cluster showers in the Rotterdam region.

Proactive water management
The Smart water team is assigned to improve the accessibility of data gathered by the city’s Rain Radar, enabling end-users such as traffic information systems and pumping stations to response proactively to extreme weather events.

A high volume of data has already been gathered by the radar but a client consortium of the City of Rotterdam, three local water authorities and the province of Zuid-Holland has taken the next step by engaging a team, led by Royal HaskoningDHV and including experts from Nelen & Schuurmans and Infoplaza.

Hanneke Schuurmans, project manager for Royal HaskoningDHV said, “Rotterdam is leading the way in the creation of climate resilient cities. We will work in close corporation with SkyEcho and TU Delft, who are developing specific software to transform the radar signal into rainfall intensities.”

dws-rhdhv-rain-radar-schuurmans-350px Hanneke Schuurmans of Royal HaskoningDHV at the Adaptation Future conference in 2016 in Rotterdam. 

Combination of radars
“We will combine this data with data from six other radars and use this to develop forecasts”, Schuurmans continues. “As a result we will improve our current rainfall images by a factor of 100, making forecasting 100 times more accurate.”

“These improvements will result in a wealth of applications designed to improve the resilience of city services from control of pumping stations and storm water collection to traffic management during extreme rainfall.”

Embracing available technology
Johan Verlinde, Asset Manager Water, City of Rotterdam said: “Rotterdam is proud to be recognised as one of the world’s leading resilient cities but as climate continues to change and our city continues to grow, we must embrace the available technology to ensure that our infrastructure and residents are better prepared to adjust to those changes.”

Royal HaskoningDHV has extensive experience in the creation of smart water solutions having recently delivered a high profile Flash Flood Forecasting app to the citizens of Ghana and are currently working on a Flood Information System for Parramatta Sydney (Australia).

Work on the Rotterdam project started in April and is expected to run for two years. The team expects initial work will be complete by June, allowing the system to catch the intense rainfall events that mostly occur in the summer months.

Together with Wetlands International the consultant is conducting the environmental risks assessment in order to inform the stakeholders on the baseline of the drought conditions.

The mapping by the two Dutch-based organisations is part of the Protracted Crisis Horn of Africa (PCHA) project.

The ultimate aim of the project is community stability and resilience through strategic interventions for food security, water security and disaster risk reduction.

dws-acacia-pcha-south-sudan-map2-350px Conflict density areas (red = high) in South Sudan, July-October 2016 (source: FEWS network)

Degrading ecosystems
The Kinneti River flows northward from the Imatong Mountains eventually dispersing into the wetlands of Badingilo National Park, north east of the capital Juba.

The Kinneti river flows from a mountain range (Mt Kinyeti 3170 m) near the Ugandan border through the Torit country. The catchment has a high biodiversity,

Today, many locals are heavily dependent on the wetland and forest reserve for timber, firewood, charcoal, bush meat and arable land.

Such activities provide an income and survival of people within the region but are not sustainable. The ecosystems in the area are degrading.

dws-acacia-south-suden-burned-areas-350px Burning of vegetation by fighting parties adds to the reduction of crop yields, next to the poor soils and unpredictable rainfall.

Inconsistent rainfall
Over the last decade, the Kinneti river catchment has experienced droughts, inconsistent rainfall patterns and floods.

Activities such as deforestation, hillside farming and agriculture in wetlands has led to soil erosion and reduced water conservation in soils.

The poor soils and unpredictable rainfall has led to significant reduction in crop yields over the years.

This is affecting the food security for humans and animals and increasing the community’s competition for pasture and water.This news item was originally published on the website of Acacia Water.

Paper mill Estonian Cell produces 1.5 times more biogas from waste water using ECSB-technology https://www.dutchwatersector.com/news-events/news/25159-paper-mill-estonian-cell-produces-1-5-times-more-biogas-from-waste-water-using-ecsb-technology.html dws-hydrothane-estonia-cell-biogas2-770pxLast year pulp and paper mill Estonian Cell of Heinzel Holding in Estonia, increased its biogas production by 1.5 times. One third of the total energy used in the pulp mill comes from the biogas produced in the waste water treatment plant.

At the heart of the biogas production is the ECSB reactor of Dutch-based firm HydroThane that is in operation since January 2014.

The ECSB reactor with more than 4,000 m3 volume is the largest single ultra-high rate granular anaerobic reactor for waste water treatment in Europe.

dws-hydrothane-estonia-cell-biogas2-350px Waste water treatment and biogas production plant at pulp and paper mill Estonian Cell.

Own produced biogas
Estonian Cell produced 7.7 million m3 of biogas in 2016, compared to 5 million in 2015, and contributing to replacing nearly 50 GWh of natural gas by biogas.

“This was remarkable achievement as the internal project targets were exceeded by more than 50 percent”, explained Lauri Raid, a member of the management board of Estonian Cell.

Lauri Raid believes that the investment has a substantial positive environmental impact as it reduces the ecological footprint of the production even further and also decreases the company’s production costs.

The pulp and paper mill used to consume more than 15 million cubic meters natural gas of fossil origin but now the mill has replaced a whole third of it by 5 million cubic meters of bio-gas produced on site.

In 2016 Estonian Cell received an recognition from the competition The Best Estonian Enterprises and was named the Innovator of the Year 2016.

Two stage process
Hydrothane’s external circulation sludge bed (ECSB) is a high-rate anaerobic digestion system that uses granular biomass to treat wastewater.

The ECSB reactor has a two stage process, allowing a good biomass retention and high organic loading rates. Another advantage of the two stage process is the higher stability.

Its typical loading rates in the range of 15 to 35 kg COD/m3.day, which makes this technology suitable for waste water treatment at breweries, beverage plants, biofuel processors, or the pulp and paper industry.

Groningen Seaports commissions port-based InvaSave system to treat ballast water https://www.dutchwatersector.com/news-events/news/25108-groningen-seaports-commissions-port-based-invasave-system-to-treat-ballast-water.html dws-damen-invasave-ballast-delfzijl-770pxFollowing two years of intensive testing, Groningen Seaports officially commissioned the InvaSave 300 port-based ballast water treatment system in the ports of Delfzijl and Eesmhaven, the Netherlands, on 25 April.

Delfzijl and Eemshaven are the first harbours in the world with a commercial operator that offers the IMO certified ship-to-ship treatment of ballast water.

The port-based InvaSave system has been developed by Damen Shipyard.

dws-damen-invasave-ballast-uv-filtration-350px  InvaSave is based on continuous fine filtration combined with Ultra Violet treatment.

Port-based treatment
In September the IMO convention for management of ships' ballast water (BWM) will enter into force. It requires international navigating ships to destroy harmful organisms before disposing their ballast water.

Treatment is possible with an on board treatment unit, but as an alternative ports can offer the treatment of ballast water as a service.

First commercial operator
Mariflex is the first operator in the world to offer this port service in the ports of Delfzijl and Eemshaven.

The company operates a pontoon for ship-to-ship operations to connect ships to the InvaSave 300 treatment unit that has specially been developed for this purpose by Damen Shipyard.

The treatment meets the IMO D-2 standard to eliminate potentially invasive marine micro-organisms

Both ports are very close to the Wadden Sea which is a marine protected area. This makes the port authority keen on providing this harbour service, preventing the spreading of non-native species via the discharge of ballast water.

dws-damen-invasave-delfzijl-350pxAlternative for onboard retrofit
Philip Rabe, responsible for InvaSave sales at Damen, commented: “We’re delighted that the Damen InvaSave is finally operational in a commercial environment. It is a unique product and, in many cases, it enables ports to offer vessel owners a viable and cost-effective alternative to retrofitting onboard systems.”

According to Rabe, ports now have the opportunity, in the event of failure of an onboard system, to offer owners a means by which they can access ballast water treatment at short notice, ensuring minimal downtime.

Second unit in Rotterdam
The IMO-approved Damen InvaSave is the world’s first external ballast water treatment unit designed primarily for use in ports.

The new unit is now ready for operations at the harbour of Delfzijl and Eemshaven for vessels either without, or with malfunctioning, onboard BWTS capability. MariFlex also plans to have a second operational in Rotterdam ahead of the September implementation of the IMO Ballast Water Management Convention.

Tidal Bridge shifts gear for floating bridge with tidal power plant in Larantuka Strait, Indonesia https://www.dutchwatersector.com/news-events/news/25059-tidal-bridge-shifts-gear-for-floating-bridge-with-tidal-power-plant-in-larantuka-strait-indonesia.html dws-tidal-bridge-larantuka-concept-640px
Tidal Bridge, a joint venture of Strukton International and DEC, has started the feasibility study for the Palmerah Tidal Bridge project in Indonesia.

The first scope of the project consists of the construction of a 800 m floating bridge to cross the Larantuka Strait connecting the islands of Flores and Andonara.

Additionally the bridge is to include a tidal energy power plant with a capacity of 18 to 23 MW.

The Palmerah Tidal Bridge project has the National Strategic Project status, emphasizing the national interest.

dws-tidal-bridge-larantuka-strait-350px The Larantuka Strait between Flores (left - city of Larantuka) and Andonara (right).

Cutting edge technology
Eric van den Eijnden, CEO Tidal Bridge said: “We are proud to contribute to this bridge with cutting-edge technology and the largest tidal power plant in the world and in so doing be able to increase the living standard of the people.”

“This milestone is an extraordinary momentum to show our knowledge and experience”, said André Hoogeveen, General manager Strukton Sustainable Energy. “It is great to have the opportunity to contribute to this state of the art product in Indonesia.”

Great potential for tidal energy
The combination of the bridge with the tidal energy power plant makes this project unique in its kind. The planned location, Larantuka Strait, is highly suitable for the generation of tidal energy due to the water flows.

After realising the first phase, the project may be followed by an extension and finalisation of the power plants to an installed capacity of 90 MW to 115 MW for more than half a million people.

dws-tidal-bridge-larantuka-agreement-350px Tidal Bridge and Indonesian national and local authorities agreed on a roadmap to construct a bridge in April last year.

Dutch-Indonesian cooperation
The start of this feasibility study follows the signing of the Head of Agreement in April 2016. It is the first project as part of the Dutch - Indonesian cooperation in the area of water works.

The project is endorsed by the Dutch Ministry of Infrastructure and the Environment, the Dutch Embassy in Jakarta, the Indonesian province NTT, the Ministry of Energy, Public Works & Marine, and the Indonesian Embassy in The Hague.

About TidalBridge

Dutch algae treatment firm LG Sonic placed two solar-powered algae control MPC-buoys in Coatesville reservoir in Pennsylvania, USA. This reservoir is used by a subsidiary of American Water as a source for drinking water.

The MPC-buoy systems control algae growth in the reservoir with specific ultrasonic waves based on real-time water quality.

This is the third joint project by LG Sonic and American Water. Other algae control projects are running in Hawaii and New Jersey.

dws-lg-sonic-american-water-coatesville-350px The MPC-Buoy installed in Coatesville reservoir, Pennsylvania, USA.

Official innovation partner
LG Sonic is an official innovation partner of American Water, following the installation of four MPC-buoys in a reservoir at the Canoe Brook water treatment plant in Short Hills, New Jersey in 2014.

Extensive testing showed that the MPC-Buoy systems had a significant impact on the algae, allowing the treatment plant to reduce chemical consumption by more than 20 percent.

Together with American Water, LG Sonic is looking to treat other reservoirs impacted by algae including clarification basins, waste backwash lagoons and wastewater/reuse applications.

Large water surfaces
The MPC-Buoy is a solar-powered system that combines continuous online water quality monitoring, web-based software, and ultrasonic technology to effectively control harmful algal blooms in large water surfaces, such as lakes and drinking water reservoirs.

MPC-Buoy systems have been installed in lakes and water reservoirs in, among other countries, the United States of America, Canada, Singapore, New Zealand, and the United Kingdom.

Degradation of wetlands in the Sahel drives massive migration to Europe https://www.dutchwatersector.com/news-events/news/24999-degradation-of-wetlands-in-the-sahel-drives-massive-migration-to-europe.html dws-wetlands-watershock-ewaso-ngiro-protest-770pxPoor management of water resources is an overlooked cause of migration from Africa to Europe, stated Dutch-based foundation Wetlands International at the presentation of its new report Water shocks: Wetlands and Human Migration in the Sahel.

The report was presented in Brussel at the Red Cross EU office in Brussels on 3 May.

“We like to address the blind spot on the role of water in wetlands in these regions and the link to Europe”, said Wetland’s CEO Jane Madgwick on the occasion.

She urged for wetland’s restoration as it is needed for water security, being essential for human well-being and economic development.

dws-wetlands-watershock-map-sub-sahara-350px   Six major wetlands cover more than 10 percent of the Sahel when they are in full flood (Water shocks, 2017).   dws-wetlands-watershock-map-immigration-350px    Most of the migrants arriving by boat in Italy (January-November 2016) come from the Sahel region (UNHCR, 2017)  

Blocking prosperity
The report points out that human displacement is a common situation in the Sahel region. One of the examples mentioned is the situation around Lake Chad on the border of Chad, Niger, Nigeria and Cameroon.

Insurgencies by militant Islamist group Boko Haram has displaced more than 2.3 million people since mid-2013, including 1.3 million children.

The Lake Chad Basin has lost 95 percent of its surface area due to water abstraction for irrigation projects, and youths from this region are joining armed groups because of lack of opportunities.

Less floods
Another example from the report is the reduced inflow to the Inner Niger Delta of Mali as a result of impacts of the Selingue reservoir and offtakes for irrigated agriculture.

The inflow to the inner river delta has reduced by 16 percent in a relatively dry year, causing a reduction of the flood extent by 1400 square km, reducing livestock, fish and rice production for around two million people.

Models predict that construction of the planned Fomi Dam in Guinea and extension of the Office du Niger irrigation scheme would lead more drought.

This could cut fish catches in the delta by 31 per cent and reduce the pastures by 28 per cent.

Natural resources
“Driving forward inclusive and sustainable development in the Sahel is an urgent, global priority” said Jane Madgwick. “But this will only be achieved by shifting from the traditional development paradigms and hard infrastructure schemes which play havoc with the natural hydrology of the region.”

According to Madgwick it is essential to maintain and restore the natural resource base. “It is essential to increase water and food productivity and provide livelihood strategies to cope with a changing climate.”

“In this context, wetlands such as river floodplains and lakes are disproportionately important; especially to the most marginalised and poor people of the region,” she said.

dws-wetlands-watershock-presentation-madgwick-lahr-350px CEO director Jane Madgwick (left) of Wetlands International and Juriaan Lahr (right) of the Red Cross during the presentation of the report in Brussels.

Call on NGOs
Juriaan Lahr, Head of International Assistance of the Netherlands Red Cross Society, added a message for humanitarian organisations. “They need to connect their work with the environmental and development actors to find durable solutions.”

“We need to understand better the complex and multifaceted drivers of involuntary migration, social conflict and poverty, which may be rooted in the depletion of natural resources,” Lahr said.

Economic costs
Four cases mentioned in the report illustrate the economic cost of losing the Sahelian Wetlands:
● The drying out and siltation of the Senegal River’s large coastal delta due to the Manantali Dam has resulted in the loss of 90 per cent of its fisheries.
● The Maga Dam and a water diversion scheme on Cameroon’s Logone River floodplain damaged downstream flood-recession agriculture, pastures, fisheries and wildlife tourism. These changes annually cost 2.5 million euros against the 10.7 million euros a year that the annual flooding contributed to the local economy.
● The planned Fomi Dam in Guinea could cut fish catches in the delta by 31 per cent and reduce the pastures by 28 per cent.
● Dams in northern Nigeria have reduced the Hadejia-Nguru wetland. The benefits of the floodplain ranged from approximately 9,600 to 14,500 US dollar/m3 of water, compared with 26 to 40 US dollar/m3 for the irrigation project.

This significant funding round is led by San Francisco-based philanthropists Marc and Lynne Benioff and an anonymous donor. Other supporters include the Julius Baer Foundation, Royal DSM, and Silicon Valley entrepreneur/investor Peter Thiel.

The foundation recently conducted trials in the North Sea to test the behaviour of a new developed boom on waves (on top photo).

dws-ocean-cleanup-funding-concept-350px  The concept is to use the rotating currents in the ocean to concentrate the plastic garbage  so its can be removed and disposed.

Plastic capturing technology
Over the past four years, The Ocean Cleanup has been developing a passive plastic capturing technology, which uses ocean currents to catch and concentrate the plastic, reducing the theoretical clean up time of the Great Pacific Garbage Patch from millennia to years.

The Ocean Cleanup aims to launch its first experimental clean up system in Pacific waters by late 2017.

It will represent the most important milestone on the road to the full-scale clean up of the world’s oceans.

dws-ocean-cleanup-funding-pacific-350px Three big garbage patches that float around in the Pacific ocean.

Impacts on future of oceans
"Lynne and I are thrilled to support The Ocean Cleanup's important goal of eliminating plastic in oceans," said philanthropist Marc Benioff, Chairman and CEO, Salesforce.

"With Boyan's innovative leadership, I believe The Ocean Cleanup will have an incredibly positive impact on the future of our oceans. I hope other leaders will join us in supporting these efforts."

Boyan Slat, founder and CEO of The Ocean Cleanup, stated: “Our mission is to rid the world’s oceans of plastic, and this support is a major leap forward towards achieving this goal. Thanks to the generous support of these funders, the day we’ll be returning that first batch of plastic to shore is now in sight.”

More details on the large-scale trials will be released shortly.

The world’s first Climate Adaptation Academy was launched by C40 Cities network in Rotterdam, the Netherlands on 2 May. The academy started off with its first delegation from the city of Dubai, to participate in the inaugural adaptation Master Class.

The Climate Adaptation Academy will provide cities with training programmes and technical support in climate change adaptation and building resilience.

dws-c40-rotterdam-academy-dubai-students-350px Delegation from Dubai participated in the first master class.

Prepare for climate change
City officials and urban planners from more than 60 cities around the world, will learn how to prepare their cities for the inevitable consequences of climate change.

“Every city on earth is vulnerable to some degree to the impacts of climate change, whether from floods, droughts or heat waves,” said Ahmed Aboutaleb, Mayor of Rotterdam.

Mayor Aboutaleb: “This will have an enormous impact on public health, quality of life and the economic progress in our cities. To protect our citizens, city leaders need to implement immediate measures, and the C40 Adaptation Academy will ensure the best ideas are spread around the world as quickly as possible.”

dws-c40-rotterdam-academy-aboutaleb-350px Rotterdam mayor Ahmed Aboutaleb at the COP22 climate summit in Paris in 2015 where Rotterdam received the C40 Cities award.

Serious risks
Unless preventative action is taken, climate change-related natural disasters have been estimated to put 1.3 billion people at risk by 2050 and destroy assets worth 158 trillion US dollar.

As cities are home to more than 60 percent of the world population and the majority of global infrastructure and assets, they are uniquely vulnerable to these risks.

Parts of Rotterdam are more than 6 metres below sea level, exposing the city to serious risks from rising sea levels and other climate related threats.

By necessity Rotterdam has taken a leader’s role in climate change adaptation. Within the C40 network, the city shares this expertise with other cities around the world.

Adaptation strategy
“The effects of climate change are already underway and cities are on the frontline”, said Anne Hidalgo, Mayor of Paris and Chair of C40.

Mayor Hidalgo: “Rotterdam has recognized those risks and then worked tirelessly to spread their knowledge to other cities facing the same threats. We certainly drew on their expertise when creating Paris’ award-winning Adaptation Strategy”.

EU commission publishes Urban Water Atlas about 40 cities https://www.dutchwatersector.com/news-events/news/24925-eu-commission-publishes-urban-water-atlas-about-40-cities.html dws-eu-atlas-amsterdam-dakdoktors-terras-770pxThe European Commission published the Urban Water Atlas for Europe, a complete panorama of water management in European cities.

The publication include the Blue City Index of 40 European cities on 25 water related topics. In Europe Amsterdam is the best performing city with a BCI of 8.3 (on top photo - Rainproof project). The City Blueprints, developed by KWR and also provided in the atlas, show cities’ performance in terms of overall water management.

dws-eu-atlas-bci-amsterdam-400px  Amsterdam has six maximum scores, including on the energy efficiency of waste water treament. 

Two major barriers
According to Kees van Leeuwen (KWR) and Richard Elelman (NetwercH2O), coordinators of the City Blueprints project, there are two major barriers for cities to keep up with the increasing demand for water.

Van Leeuwen en Elelman mention the increasing costs and the increasing complexity of the water issues. “Many cities have old systems and the cost of urban infrastructure is staggering,” they write.

Additionally they address in the atlas the complexity of managing major infrastructure developments in dense and rapidly growing cities.

Their advice to cities is not to wait for damaging events to occur that forces cities to make responsive investments. Instead cities should plan and invest in advance.

Best practices
The Urban Water Atlas for Europe provides a wealth of information on best practices, viable solutions that can be of use to city officials and urban water experts.

An interesting feature of the atlas is the fact that a lot of water is required to produce food, but very different quantities are needed for the production of different types of food.

Blue city index
The atlas also includes the City Blueprints of 40 European cities, illustrating the city’s water demand and availability, flood and drought risk, trends and pressures and water footprint.

For each city, the atlas also provides the Blue City Index, which varies from 0 to 10. This is the overall score based on the 25 indicators of the City Blueprint.

The Urban Water Atlas for Europe can be downloaded for free from the EU book shop as a pdf file (82 mB).

Heavy lift Pioneering Spirit takes Brent Delta oil platform from its legs in 12 hours https://www.dutchwatersector.com/news-events/news/24899-heavy-lift-pioneering-spirit-takes-brent-delta-oil-platform-from-its-legs-in-12-hours.html dws-allseas-brent-delta-770pxThe first of Shell’s four oil platforms in the Brent field, North Sea, has been lifted from its legs for transportation to a scrapyard in the UK on 28 April.

The lifting of the 24,000 tonne topside of the Brent Delta was done by the specialised heavy-lift ship Pioneering Spirit owned by the Swiss-Dutch company Allseas.

The lift operation, comprising move around the platform, yoke connection, de-ballasting and lift, took just 12 hours.

The Brent Delta topsides sat on a three-legged structure which stands in 140 m of water.

dws-allseas-brent-yoke2-350px Sixteen yokes (two on photo in grey-red) lifted the 24,000 tonne steel topside from its concrete legs.

World lifting record
It was the second decommissioning job for the Pioneering Spirit. In August last year the vessel lifted and removed the topside of the 13,500 tonne Yme mobile offshore production unit in the North Sea.

This time the topside was much heavier. The topside of the Brent Delta weighs 24,000 tonne, resulting in a single lift world record.

According to Allseas their 382 m long Pioneering Spirit has a capacity to lift and remove topsides of offshore platforms up to 48,000 tonne.

Leaving legs in place
The Brent platforms became an issue of public concern in 1995 when Greenpeace activists occupied one of the platforms, opposing to Shell’s plans to sink the platforms.

Now Shell intends to lift, remove and scrap all four Brent platforms and supporting facilities, including the 30,000 tonne topside of the Brent Alpha platform.

It wants to leave parts of the structures in place, including the concrete and steel legs of the four Brent platforms. Environmental groups as Greenpeace and the World Wildlife Fund Scotland have posed this plan as they want Shell to remove the legs too.

dws-allseas-brent-stinger-350px Next assignment for the Pioneering Spirit is to lay a 900 km long gas pipeline in the Black Sea. A special ‘sting’ (in white, right) to guide the pipe-laying was tested on the vessel in the Rotterdam harbour in March.

New standard for decommissioning
The removal of the Brent oil platforms is seen as a new standard for decommissioning of offshore structures.

Shell expects 470 installations, including wells and pipe lines, to be decommissioned in the Brent field over the next 30 to 40 years. In the wider North Sea, industry experts expect to see around 600 installations decommissioned.

The topside of the Brent Delta oil platform was sea-fastened on board the vessel and transported to Teesside, UK. There the structure was transferred to a barge that will bring the structure into the river Tees and to Able Seaton Port.

Ultimately Shell’s aim is to recycle 97 percent of the Brent Delta topside.

Water education institute IHE Delft starts new life at age 60 https://www.dutchwatersector.com/news-events/news/24870-water-education-institute-ihe-delft-starts-new-life-at-age-60.html dws-ihe-60-holzwarth-770px
IHE Delft Institute for Water Education celebrated its 60th anniversary introducing a new rector, a new strategy and a new relation to the United Nations.

Interim rector Fritz Holzwarth of IHE Delft opened the celebration that took place in Delft, the Netherlands on 24 April. Holzwarth reflected on the anniversary and the impact of the institute’s 15,000 alumni working in the water sector around the globe.

dws-ihe-60-moors2-350px While celebrating its 60th anniversary, IHE Delft introduced its new rector Eddy Moors. He will start on 1 July.

Lifelong learning
“On this day we really want to look forward”, he said. “and discuss the role of the institute when it comes to innovation and to influence”.

Holzwarth mentioned the changing environment that awaits the graduated students when they return home and take a job in the water sector. The water issues get more complex and solutions demand an integrated approach, not just an engineering approach.

“We want to bring capacity building to a new level. It goes beyond the four years of education here in Delft”, he said. “Our drive should focus on a lifelong learning and changing mind sets.”

New relation to United Nations
The opening remarks relate to the new position of the IHE institute within the United Nations. It seeks to become more independed, to become a category 2 institute under the auspices of Unesco, rather than being part of Unesco as it has been for the past 14 years. 

Other speakers at the celebration support Holzwarth’s suggestions to focus the education more on water management, including social impact, instead of engineering only.

dws-ihe-60-hasan-350px PhD fellow Shahnoor Hasan at IHE Delft questioned her career opportunities in a water sector that is domnated by male engineers.

Managers versus engineers
Ambassador of Bangladesh to the Netherlands, Sheikh Mohammed Belal, shared this vision and confirmed that Bangladesh needs more specialists with a holistic view on water issues.

One of such students is Shahnoor Hasan, a PhD fellow at IHE Delft. On stage at the celebration, she showed her concerns about her career in Bangladesh as a women and a non-technical skilled water engineer. “What are my opportunities”, she asked the ambassador.

The ambassador shared her concern and confirmed that the top of the water sector in Bangladesh is still dominated by male engineers.

Dutch context
Hasan also reflected on her study in the Netherlands. She emphasized the importance of learning how the Dutch water sector makes long-term plans for a river delta as a whole. “However it is a one way journey”, she said”. “The Dutch have all the knowledge and I am missing the context of Bangladesh”. She advocated to replicate the learning of a Delta planning process without the typical Dutch context.

Hasan suggested to start educating Dutch water managers in Bangladesh where they can use their knowledge in the context of the situation in Bangladesh.

Two award winners were from the Netherlands. Elemental Water Makers won the Innovative Projects Award. Research institute TNO won an award in the category institutions.

The award is worth 1 million US dollar and was launched by the sheikh to encourage the worldwide development of innovative and sustainable solutions for clean-water scarcity, using solar power.

dws-ewm-mbram-award-all-winners-350px  All winners of the Mohammed bin Rashid Al Maktoum Global Water Award.

Solar powered RO
The first place in the category Innovative Projects Award went to the company Elemental Water Makers from the Netherlands, for a solar-powered Reverse Osmosis (RO) plant to produce drinking water.

The young Dutch start up entered the competition with its plant on the British Virgin Islands. The plant produces 12,500 liters of fresh water each day using only 12 kWp solar energy.

The low energy consumption is possible as the seawater is pressurized by gravity before it is desalinised by the reverse osmosis process.

Founders Reinoud Feenstra (left on top photo) and Sid Vollebregt (right) received the award in Dubai from the initiator of the award Mohammed bin Rashid Al Maktoum (middle).

Membrane distillation
The first place in the category Innovative Research and Development Award - International Institutions, went to the Netherlands Organization for Applied Scientific Research (TNO), in cooperation with the Qatar General Electricity and Water Corporation (Kahramaa), for a solar-powered desalination technology based on TNO’s high-efficiency membrane distillation concept.

dws-ewm-mbr-award-stage2-350pxDesalination using solar energy
The Mohammed bin Rashid Al Maktoum Global Water Award is patronised by UAE water aid foundation (Suqia), an initiative to provide water for people world wide.

In his keynote speech, chairman HE Saeed Mohammed Al Tayer of UAE water aid, noted that the award aims to stimulate finding solutions to water scarcity and the provision of clean water using modern technologies, and purification and desalination of water using solar energy.

“We are committed to achieving one of the key objectives set by the Mohammed bin Rashid Al Maktoum Global Initiatives foundation, which is to combat poverty and diseases by contributing to finding permanent and sustainable solutions to water scarcity around the world”, the chairman said.

About UAE water aid (Suqia)
Suqia was launched in June 2014 as a campaign by HH Sheikh Mohammed bin Rashid Al Maktoum, to provide drinking water to 5 million people around the world. It concluded successfully after collecting AED 180 million in 18 days, enough to complete projects to provide drinking water to the needy around the world.

Suqia works to combat poverty and disease, one of the objectives set by the Mohammed bin Rashid Al Maktoum Global Initiatives.

Tidal Technology Center granted 4 million euro for test facility Grevelingen, the Netherlands https://www.dutchwatersector.com/news-events/news/24835-tidal-technology-center-granted-4-million-euro-for-test-facility-grevelingen-the-netherlands.html dws-ttc-impression-770pxThe Dutch government has granted the Tidal Technology Centre Grevelingen 4.1 million euro for its initiative to build three testing channels for tidal turbines in Grevelingen, the Netherlands.

The grant is part of a 25 million euro package to stimulate the regional economy. The package also includes funding for a living lab research programme on integrated issues in river delta’s such as energy, flood protection and food security.

dws-ttc-flakkeese-spuisluis-350px

The Flakkeese sluice in the Grevelingen dam has recently been upgraded by Dutch national public works Rijkswaterstaat. Depending on the tides the water can now flow in either direction. 

Research on tidal energy
The three testing channels will be located in an existing drainage sluice in the Grevelingen dam that connects lake Grevelingen to the Eastern Scheldt tidal bay.

The channels will include monitoring and datalog systems for developers of tidal turbines to test, demonstrate and certify their products.

It will also feature 4 demonstration turbines that will be made available to research institutes and universities for independent research.

The centre reports that it has 20 interested parties to use the test facilities.

Higher water speeds
Tidal turbines that are built in a dam or storm surge barrier operate under different circumstances than the ones in open sea.

Compared to a free-stream offshore setting, the speed of the passing water is much higher. On the other hand the differences between high and low tides are lower and there is limited space in the dam or barrier.

The centre aims to contribute to innovation and development of tidal turbine techniques for low head water streams.

The Tidal Technology Centre is expected to be completed in 2017-2018.

Dutch armed forces facilitate field tests for promising water technologies in Mali https://www.dutchwatersector.com/news-events/news/24788-dutch-armed-forces-facilitate-field-tests-for-promising-water-technologies-in-mali.html dws-mali-sunglacier-twin-desert-770pxThe Dutch Ministry of Defence invited teams of SunGlacier and The Hague University to its military camp in Mali, to test three new mobile water technologies under the extreme dry and hot weather conditions in the desert.

Most remarkable was the achievement by SunGlacier that harvested a small amount of water from the air by using a 3 Euro peltier cooling element from a computer. The field test was conducted at a temperature of 45 degree Celsius and an air humidity below 5 percent.

The other two technologies were a compressor to produce water from air and a compact device for the production of drinking water from rivers, lakes or pools. The collected water samples ate in the process of being analysed on the drinking water quality.

The teams returned last week and presented their results at a press conference in The Hague, the Netherlands, on 25 April. 

dws-mali-sunglacier-middendorp-350px  Commander of the Dutch armed forces, general Tom Middendorp told at the press conference that there were several good reasons to facilite the field tests.

Desert conditions
The Netherlands chief of defence, general Tom Middendorp, personally invited the two teams to do the field tests at the military camp near Goa, Mali.

The Dutch armed forces operate the camp since April 2014 to support the United Nations Multidimensional Integrated Stabilization (Minusma) mission in Mali.

According to Middendorp there were plenty of reasons for him to support these field tests under desert conditions. “Just image if there were small, inexpensive devices available that can produce drinking water all over the world.”

There is also an own interest, the general admitted, referring to the logistics of the military camp. “For our military camp in Mali we have to bring in large quantities of drinking water and these technologies can potentially make the camp more self-sufficient. By reducing the use of groundwater the camp has less impact on the water resources of the local people ”.

dws-mali-sunglacier-twin-desert-350px. SunGlacier team with inventor and artist Ap Verheggen (standing) and solar specialist Peter van Geloven working on their Twin Desert device

Below dew point
Two of the three new water technologies concerned the harvesting of water from the desert air. The challenge was to cool down the hot desert air to below the dew point.

SunGlacier has designed a solar-powered, water maker based on Peltier technology that operates without needing batteries or a current inverter.

A solar panel generates power for an 18W Peltier element, which cools a cone-shaped aluminium block to below the ambient dew point. The water condensates on the cone and drips down.

This device can generate only small quantities of water, and the SunGlacier team took the opportunity to also test its Desert Twin system using solar-driven compressor.

Potentially this technology can produce water from desert air in larger quantities.

Initially it proved to be too hot for the system to produce water from the air, but eventually the SunGlacier team managed to cool down the air inside the device to below the dew point.

dws-mali-boomym3-350px Engineers Damon Golriz (front) and Emad Khatibzadeh analysing the results of the EDI treatment of the river water.

Treatment of river water
The third technology involved, was on the treatment of water from the nearby Niger river. Engineers for peace Emad Khatibzadeh and Damopn Golriz, had the opportunity to test the latest version of the desalination system based on a combination of electrodeionization (EDI) technology and UV filtration.

In close cooperation with the Hague University, this new desalination device is being developed to provide cheap drinking water or irrigation water in remote areas with no electricity grid.

A prototype has already produced 20 litres in an hour, using as little as 200 Watt input from a solar panel. In Mali a version has been tested with new components.

Dutch scientists chart coastal flooding: 50 percent more people at risk in 2080 https://www.dutchwatersector.com/news-events/news/24755-dutch-scientists-chart-coastal-flooding-50-percent-more-people-at-risk-in-2080.html dws-deltares-coastal-flooding-world-map-770pxThe combination of land subsidence and sea-level rise will increase the coastal flood prone zones in the world and increase the number of people exposed to the risk of flooding by 20 million in 2080.

Researchers Dirk Eilander of Deltares and Philip Ward of VU University Amsterdam presented this outcome of their study at the annual assembly of European Geosciences Union in Vienna, Austria, on 25 April.

Eilander and Ward studied the risk of flooding on all coasts throughout the world until the end of this century. For this they extended the Aqueduct global flood analyser tool that now also includes data on coasts and seawater level.

Coastal zones with increasing potential flood victims are located in four countries: China, Bangladesh, India and Indonesia (see top map: grey = baseline of people exposed to coastal flooding 1:100; bleu = additional numbers because of sea level rise).

dws-deltares-egu-eilander-350px Reseacher Dirk Eilander at Deltares presenting the results of the study at the press conference in Vienna.

Coastal flood hazard
The existing Aqueduct platform, launched by Deltares and World Resource Institute in 2015, charts the river flood prone areas worldwide.

Eilander and Ward teamed up with other researchers to extend the use of this platform to include coastal flooding and integrate data about changes in seawater levels, as well as global land subsidence in combination with the probabilities of spring tides.

According to Dirk Eilander the new figures provide a good picture of where risk levels are highest around the world. “Although some large countries stand out in absolute numbers, the generally smaller island states will be affected most in relative terms”, he added.

Simulate tides and storms
For the first time, the researchers have used physically-based models with global coverage to simulate tides and storms at sea. Moreover, a new method has been used to chart coastal flooding worldwide more accurately.

The geographical data and elevation data for the coastal areas have been entered accurately in the models used, taking into account steep or gentle slopes and local vegetation.

Buildings and population densities on the coasts were used to map out flood impacts.

The extended Aqueduct tool will make it easier for coastal populations to understand their flood risk and how it might change in the future.

dws-deltares-egu-scheme-350px Researchers used new method to simulate tides and storms at sea.

Concentration in four countries
Ten percent of the world's population live in low-lying areas less than ten metres above sea level. Many of these areas are at risk of flooding.

The expectation is that, as a result of sea-level rise and land subsidence, 50 percent more people could be affected in 2080 by severe floods that occur once every hundred years.

Population growth and migration have not been included in this estimate.

The extension of the Aqueduct platform has not quite been completed yet. The platform will be made available to the general public this year.

Loss of wetlands in Sahel linked to migration into Europe https://www.dutchwatersector.com/news-events/news/24736-loss-of-wetlands-in-sahel-linked-to-migration-into-europe.html dws-wetlands-launch-sahel-700pcDutch-based organisation Wetlands International will release a publication in Brussels on 3 May that links the loss of wetlands in the Sahel region to increased social tensions and involuntary migration into Europe.

The foundation that strives for the protection of wetlands worldwide, has announced the launch of its report that is titled Water Shocks: Wetlands and Human Migration in the Sahel.

Devastating water infrastructure
In the announcement Wetlands International states that development schemes are undermining the livelihoods of some of the most vulnerable and poor inhabitants of the Sahel, due to loss and degradation of wetlands, whose productivity depends on seasonal flooding.

International funding is helping to build infrastructure for hydropower and irrigation schemes to meet growing energy and food demands in the Sahel Region.

dws-wetlands-sahel-ethiopia-erosion2-350px  Example of ineffective physical erosion control interventions in Ethiopia. The Gabion dams widened the gully, while trees are still being cut.

Seasonal floods
The rivers, lakes, floodplains and deltas of the Sahel are highly productive and biologically diverse ecosystems, fed by seasonal floods. These dynamic wetlands have long shaped human culture and been the basis for local and regional economies.

Tens of millions of people still depend on the vitality of these water resources. But these natural assets are degrading, often due to ill-advised economic development projects which divert the water.

Such infrastructure can have a devastating impact on the fragile habitats of wetlands.

Take action
Wetlands International calls on decision makers at national and EU levels, development banks, and actors in humanitarian and development aid to take action, this new report highlights the connections between water management, wetlands and involuntary migration, including to Europe.

Authors, Jane Madgwick, CEO of Wetlands International and Fred Pearce, journalist, will present the report, along with a representative from the Red Cross.

On the occasion a panel discussion will follow, where high-level representatives will respond to the report’s conclusions.

Large-scale extraction of Nereda alginate from waste water at wwtp Apeldoorn, the Netherlands https://www.dutchwatersector.com/news-events/news/24693-large-scale-extraction-of-nereda-alginate-from-waste-water-at-wwtp-apeldoorn-the-netherlands.html dws-rhdhv-alginate-pilot-apeldoorn770pxRegional water authority Vallei and Veluwe is conducting pilot tests for the extraction of Nereda alginate from sludge at its wwtp Apeldoorn, the Netherlands.

The first tests prove that extraction is possible at large-scale. The results of the trials will be used to build the first two full-scale alginate recovery plants by 2018-2019.

The alginate is recovered from the granule sludge that is generated at a Nereda waste water treatment plant. Nereda alginate is a substance with unique characteristics and potentially high-quality applications, like an adhesive in a fertiliser pellet.

dws-rhdhv-alginate-pilot-apeldoorn-wwtp-350px  Contributing to the circular economy, wwtp Apeldoorn delivers biogas for the production of electricity and hot water for a nearby housing area. The plant also recovers 900 ton struvite annually that can be used as an agricultural fertilizer.

Retain and repel water
Another characteristic of Nereda alginate is that it can both be used as a product to retain water but also to repel water. This means it can be widely used – for example, in the horticulture and the paper and concrete industries.

It can be used as a thickening agent or an adhesive, as a coating or as a stabiliser. Reportedly, various market parties have already shown interest in using the alginate – as a concrete coating, for example.

Adaptation of regulations on waste
In order to be able to bring Nereda alginate on the market, the existing regulations on waste have to be adjusted. Director Tanja Klip-Martin at Vallei and Veluwe: “I believe that the status of extracted raw materials should be made equivalent to that of primary raw materials. On condition there are no risks to public health when they’re deployed, because we don’t want to throw out the baby with the bathwater.”

Klip-Martin: “It is only then that we will have an equal playing field and that the Government’s aim to make the Netherlands circular by 2050 will become realistic.”

At the moment, alginate is extracted from seaweed. That is currently being done in Asia. It is a relatively expensive process. Because of this, the use of this type of alginate is mostly limited to the medical sector (including moulds for false teeth, alginate plasters).

The alginate in the sludge pellets left behind after treating wastewater with a Nereda installation is more sustainable, more economical and therefore more broadly deployable on the market.

National development programme
The extraction of Nereda alginate from wastewater is part of the NAOP National Alginate Development Programme.
In this programme, the Dutch Water Authorities cooperate with the Foundation for Applied Water Research (STOWA), engineering firm RoyalHaskoningDHV and Delft University of Technology.

HydroNET Water Control Room wins prestigious Partner for Water award 2017 https://www.dutchwatersector.com/news-events/news/24683-hydronet-water-control-room-wins-prestigious-partner-for-water-award-2017.html dws-hydrologiv-pvw-award-winners-770pxThe HydroNET Water Control Room in South Africa won the Partners for Water award 2017. The online water control room has been developed and implemented by a Dutch- South African consortium, led by HydroLogic.

As a result of the successful introduction, over 25 South African organisations are currently using the HydroNET Water Control Room to monitor the current situation of water systems and to respond to expected water usage and quality.

The Partners for Water award 2017 was handed to Leanne Reichard (right on top photo) and Bas Boterman (second left) of Hydrologic during the Waterproof event in Maarssen, the Netherlands, on 13 April.

Partners for Water is a programme by the Dutch government to stimulate the use of Dutch innovative water-related solutions in foreign urban deltas and their water supply systems. Over 80 projects funded by this programme competed for the prestigious ‘best project’ award.

Managing scarce water resources
South Africa suffers from water stress. Fresh-water demand is expected to exceed water availability by 2025. To efficiently manage the available water resources and reduce the impacts, water managers need access to historic, current and forecasted water and weather information.

The online HydroNET Water Control Room translates terabytes of data from radars, satellites, and other monitoring sources into easy to understand online decision-support dashboards.

These dashboards empower water managers to make well-informed and transparent decisions for the sustainable management of their water systems.

Right data at the right time
The jury explained: “This consortium provided a measurable contribution to solving world-water problems”.

In her reaction to receiving the award Leanne Reichard, leader of the consortium and business director at Hydrologic, mentioned the importance of an online control room in general: “It provides water authorities with the right data at the right time so they can take well informed decisions”.

Identifying water misuse
Addressing the control room at the Inkomati-Usuthu Catchment Management Agency (IUCMA),  the agency's executive Jennifer Molwantwa said: “Hydrologists, meteorologists, software developers and local experts worked closely together to tailor HydroNET to our needs. The control room helps IUCMA identifying misuse of irrigation water and gives us the tools to share the information with all our stakeholders, including our neighbouring countries. This openness creates a joint understanding of our decisions.”

dws-hydrologiv-pvw-award-oparetors-350pxBusiness case
The weather information is provided by South African Weather Service (SAWS) and on the occasion of being awarded 'best project' commercial manager Michelle Hartslief emphasised the business opportunities: “Thanks to the cooperation with the Dutch Weather Service KNMI and HydroLogic we have enhanced our data quality and data accessibility.

"Now we make all our data available through HydroNET", Hartslief continued. "Our cooperation helped to create an efficient business model.The revenue helps us to further improve our monitoring network and services. This way, all South African weather-sensitive industries benefit.”

The award-winning project started in 2012 during a workshop organised by the Kingfisher project. In that project, Dutch water boards cooperate with catchment management agencies in South Africa. Brian Jackson of the Inkomati-Usuthu Catchment Management Agency (IUCMA) immediately saw the potential of HydroNET to improve river and reservoir operations.

With the support of Partners for Water, a Dutch - South African consortium was formed to co-create climate and water services: HydroLogic, eLeaf, South African Weather Service (SAWS), Royal Netherlands Meteorological Institute (KNMI), University of Twente, WineJob and IUCMA.

About HydroNET
HydroNET is a web-based decision support system which transfers weather and water data into information, presented in sophisticated dashboards.
Its software is a Service (SaaS) solution that empowers over 2650 water professionals worldwide to make well-informed and transparent decisions for the analysis and sustainable management of their water resources. HydroNET is developed by Dutch research and consultancy firm HydroLogic.

About Partners for Water
The programme Partners for Water is a joint initiative of several departments of the Government of the Netherlands, developed to strengthen the international position of the Dutch water sector.

Wageningen University initiates water efficient greenhouse in Bekaa Valley, Lebanon https://www.dutchwatersector.com/news-events/news/24664-wageningen-university-initiates-water-efficient-greenhouse-in-bekaa-valley-lebanon.html dws-wur-libanon-green-houses-690px
Together with local companies, Wageningen University & Research will build a demonstration greenhouse in the Bekaa Valley in Lebanon. The greenhouse will include water saving techniques.

The demonstration greenhouse should encourage growers to invest a part of their earned money in new technology to increase their annual income again.

The initiative aims to share Dutch knowledge of water and agriculture with the inhabitants of the Bekaa Valley. Lebanon has taken in more than 1.5 million Syrian refugees of which many have settled in this valley, close to the Syrian border.

dws-wur-libanon-refugee-camp-350px  Many of the Syrian refugees are living with relatives or friends, but others are staying in tents near villages in the Bekaa Valley, close to the Syrian border.

Local growers
In Lebanon, like in the rest of the Middle East, water is scarce. On average there is enough rainfall for agriculture during four months. The remaining eight months of the year, the summer period - are hot and dry.

Now low quality ground or river water is given, rainwater collection hardly exists. The new constructed greenhouse will be linked to the knowledge and technology level of the local growers.

Labour intensive crops
Night temperatures in the Bekaa Valley are too low to grow cucumbers or tomatoes, but in summer it is too hot. Soilless culture may increase production level, but growers fear high investments. Trials and extension to growers and suppliers is of great importance.

The demonstration greenhouse will have a focus on labour intensive crops to increase employment in a country in which the population grew with 25 percent while its agricultural export market disappeared because of the Syrian war.

This news item was originally published on the website of Wageningen University.
