Florida and LG Sonic explore cooperation on algal problems https://www.dutchwatersector.com/news-events/news/36660-florida-and-lg-sonic-explore-cooperation-on-algal-problems.html dws-lg-sonic-mpc-buoy-california-770pxFlorida (USA) is investigating the use of LG Sonic's technology to reduce the impact of algal blooms in Lake Okeechobee on Florida's waterways. Last year, a state of emergency was declared in several counties following severe algal blooms throughout Florida.

Severe algal blooms
For many years, Lake Okeechobee has suffered from severe algal blooms, impacting not only the lake itself, but also waterways throughout the state.

dws-lg-sonic-lee-county-algae-cleanup-350ox   Lee County conducted pilots last year to clean up algae bloom (Photo: Lee County).

Commissioner Brian Hamman of Lee County would like LG Sonic to handle algal problems in the state of Florida. Lisa Brand, CTO at LG Sonic, was invited by the City of Miami to present their algal bloom solution at the Smart Cities event in Fort Lauderdale, earlier this year. During the event, challenges and solutions to issues of resilience, climate change, stormwater management, and harmful algal blooms were discussed.

Sound waves
The sound waves developed by LG Sonic target and neutralize algae, preventing them from growing and evolving into blooms.

These sound waves are harmless to humans, fish, and other aquatic life. For different algal types, such as cyanobacteria, LG Sonic produces a specific ‘song’ to target the algae and prevent the development of algal resistance to ultrasound.

dws-lg-sonic-lake-okeechobee-algal-bloom2-400px Remote sensing images from LG Sonic, obtained from satellite data, show in detail the algae levels in Florida’s Lake Okeechobee (image: LG Sonic).

Big data
By using real-time water quality monitoring and satellite data, LG Sonic is able to predict algal blooms. This allows the ultrasound technology to neutralize algae before they become a problem.

By compiling data from LG Sonic's systems all over the world, the company has built a database of algae and water quality data that enhances the treatment precision for each algal at the right time.

LG Sonic's MPC technology is already being used in more than 22 countries worldwide, including the USA, New Zealand, Dubai and the UK.

The technology has helped American Water successfully control algal blooms and eliminate chemical usage for their drinking water reservoir in New Jersey.

Dunea, Homawasco and Amref Flying Doctors commission drinking water plant in Homa Bay, Kenya https://www.dutchwatersector.com/news-events/news/36622-dunea-homawasco-and-amref-flying-doctors-commission-drinking-water-plant-in-homa-bay-kenya.html dws-dunea-homabay-kenya-dwtpDutch water supply company Dunea, together with Kenyan water company Homawasco and health organisation Amref Flying Doctors commissioned the extension of a drinking water production plant in the county Homa Bay, Kenya. The plant was officially opened on 10 April and allows Homawasco to supply safe drinking water to an additional 15,000 Kenyans. The extension work started one year ago as part of the WaterWorX programme, a programme of Dutch drinking water companies and supported by the Dutch Ministry of Foreign Affairs.

dws-dunea-homabay-kenya-kiosk-350px  Commissioning of the expansion was celebrated at a local water kiosk.

More and more people in Homa Bay county are moving to the cities and urban areas such as Kendu Bay are expending rapidly. Currently, 15 percent of the people in Homa Bay live in a slum. These people live in houses made of iron plates and there is a big shortage of toilets and clean water. As these people are also entitled to live safely and healthy, the local water supply company needs to provide toilets, hygiene and clean water.

Knowledge development and infrastructure
Dunea did not only invest in the hard water infrastructure, they also transferred knowledge and experience to the people of the local water company. Knowledge transfer included several business processes such as finance, human resources and communication.

According to Pim van der Male, on behalf of the Ministry of Foreign Affairs, this thorough approach is responsible for sustainable development, one of the distinguishing aspects of the WaterWorX programme. "Knowledge development gives a completely different dynamic, compared to just giving technical advice. Exchanging knowledge is much more sustainable and effective."

Van der Male: "The ultimate goal is to create a well-functioning water company that supplies water to everyone and can also financially support itself."

Short term improvements
Evans Nyagol, managing director of Homawasco, is very enthusiastic: "The management of Homawasco consists of young, well-trained and motivated employees. By exchanging knowledge and experience with Dunea, we are taking major steps quickly. We have confidence that we can improve our services on short term."

Wim Drossaert, CEO of Dunea on the occasion of the commissioning: "We see that our presence also gives confidence to other organisations. This creates a whole program of initiatives that strengthens the region as a whole."

dws-dunea-homabay-kenya-taps-350px Gaining trust of the local community is an important factor for success. They have to be convinced to pay a higher tariff for a better service.

Trust of local population
Drossaert emphasises the role of Amref Flying Doctors for reaching the poorest with water supply: "Amref is not only an important co-financier in the project, they also ensure that we get the trust of the local population. Amref is strongly rooted in Kenya and has a large network. That makes it a lot easier for us to do our work."

Patricia Vermeulen, CEO of Amref Flying Doctors, adds: "Together we ensure that 15,000 people will have clean drinking water and are willing to pay for it. In this way we work on a truly sustainable solution for a clean drinking water supply in the communities."

WaterWorX programme
The project in Kendu Bay and the surrounding towns in Homa Bay is part of the WaterWorX programme, supported by the Dutch Ministry of Foreign Affairs.

WaterWorx runs until 2030 and aims to improve sustainable access to drinking water to 10 million people in developing countries by 2030.

All water projects are being implemented by ten Dutch water companies in collaboration with 23 local water managers in Africa, Asia and Latin America.

Global Water Award 2019 for Nereda technology at wwtp Utrecht, the Netherlands https://www.dutchwatersector.com/news-events/news/36599-global-water-award-2019-for-nereda-technology-at-wwtp-utrecht-the-netherlands.html dws-rhdhv-gwi-wwtp-utrecht-770pxThe Nereda team of Royal HaskoningDHV won the category ‘Wastewater Project of the Year’ of the prestigious Global Water Awards 2019. The price was awarded for a new Nereda plant that is currently under construction at waste water treatment plant Utrecht, the Netherlands. The Global Water Awards 2019 ceremony took place in London on 9 April.

dws-rhdhv-gwi-nereda-team-350px The Nereda team receiving the award at the Global Water Awards 2019

Ongoing operational support
Contractor Heijmans-GMB and the client, regional water authority De Stichtse Rijnlanden, are working together with Royal HaskoningDHV, the developers of the Nereda technology. The contract includes design, construction, commissioning and maintenance of the plant for 10 years, with ongoing operational support.

The large wastewater treatment plant (see top photo) in Utrecht, the Netherlands was budgeted at 120 million euro and brings improved wastewater treatment to approximately 430,000 customers.

Important features of the new Nereda plant are the exceptional small footprint, the 30% energy efficiency improvement and the strict effluent requirements for nutrients (N total: 5 mg/l and P total: 0.5 mg/l).

Growing urbanisation
Commenting on the award announcement, René Noppeney, Global Director of Water Technology Products & Innovation at Royal HaskoningDHV said to be delighted to have won the award.

"Our Nereda technology is an established game-changer for sustainable wastewater technology. We now have over 65 Nereda projects completed or being delivered across the world", Noppeney commented. "It offers the perfect solution for countries facing growing urbanisation and improved environmental protection". 

dws-rhdhv-gwi-wwtp-utrecht-footprint-map-350px Seven newly built Nereda-reactors (left) will allow the removal of 14 existing aeration tanks (right), leaving a very small footprint for wwtp Utrecht (430,000 i.e., by Heijmans and GMB) 

Rebuilding on existing site
Construction work to rebuild the current obsolete wwtp Utrecht that was built in 1959, commenced in 2017. Due to the location of Utrecht’s sewer system, it was decided to build the new installation on the existing site. Owing to its compact nature, it was possible to construct it alongside the existing plant. The new wastewater treatment plant removes twice as much nitrogen and phosphate from the water. The purification process of the plant is much faster, so as well as being 30% more energy efficient compared to the original plant, it is also considerably smaller.

With no need for large post-settling tanks, a great deal of space has been saved. The original plant had 14 sedimentation tanks in use, which have been replaced by just six Nereda tanks.

The old plant was removed from service once the new plant had been commissioned. The project is now completed and the 10-year maintenance period has commenced.

dws-blue-deal-signing-colombia-350px  The first Blue Deal partnership was signed in Colombia with five regional water authorities to improve the water security along the Magdalena river. (Photo: Regional Water Authority De Dommel)

Water secure environment
The Blue Deal programme was launched last year by the Dutch regional water authorities and the Dutch Government as a joint contribution to achieve sustainable development goals 6.3 to 6.6 by 2030.

The overall goal is to help 20 million people in 40 catchment areas around the world to gain access to clean, sufficient and safe water.

Building on the expertise of the Dutch regional water authorities the programme focuses on long term partnerships with local water authorities in Africa and Latin America to create a water secure environment.

Local water management
‘We have a long history of addressing local water issues involving stakeholders such as citizens, farmers and businesses and we want to share our experiences with water authorities in developing and fragile states’, said Hein Pieper on the occasion of the announcement.

Pieper is vice-president of the Dutch regional water authorities and one of leaders of the Blue Deal programme.

dws-blue-deal-pieper Vice-president Hein Pieper of the Dutch regional water authorities explained the important role of the partnerhsips.

‘However, in the Netherlands we have our own culture and own way dealing with water issues. In order to create a water secure environment in other parts of the world, it is essential to include the local culture and local governances. Therefore we chose to set up long term partnerships.’

Making plans happen
The eleven partnerships involve 35 local parties and address a variety of water issues, such as enforcement, data collection, improving waste water treatment, increasing water retention capacity.

In many river catchments around the world, national and regional authorities have developed water management plans but face the difficulty to implement the measures that are needed to address the issues of too much, too little and too polluted water.

According to Pieper the Blue Deal programme is about getting plans into action and making water management operational. Often water infrastructure fails to deliver, such as waste water treatment plants (on top photo in Mali) or dams. 'By listening to our partners and sharing our experiences, we can gradually improve the siuation', said Pieper.

dws-ienw-vietnam-climate-meeting-350px 7th inter-governmental meeting on climate change adaptation and water management, attended by Deputy Prime Minister Trinh Dinh Dung and Minister Cora van Nieuwenhuizen (photo: Twitter/Dutch Government).

Strategic partnerships on water and food
The official visit highlights the growing economic relationship between Vietnam and the Netherlands, and follows up on bilateral agreements made in the past. In October 2010, both countries established a Strategic Partnership on climate change adaptation and water management. Both countries also established a Strategic Partnership on sustainable development and food security in June 2014.

Climate adaptation
Vietnamese Deputy Prime Minister Trinh Dinh Dung and Dutch minister Cora van Nieuwenhuizen both attended the 7th meeting of the Vietnam-Netherlands Inter-Government Committee on climate change adaptation and water management in Hanoi on 9 April.

In his opening speech Dung confirmed that the strategic partnership in climate change adaptation and water management continues to be a priority and an important pillar of Vietnam-Netherlands relations.

Minister Van Nieuwenhuizen offered Dutch support for the implementation of Vietnamese policies and the development of new policies.

She saw opportunities for support in water logistics, for example with inland waterways in the Mekong Delta and the modernisation of seaports and airports.

Integrated Mekong Master Plan
Consultancy firm Royal HaskoningDHV signed a contract with the Vietnamese Government to develop a spatial planning across different disciplines in the Mekong river delta to 2030, with a further view towards 2050.

Part of this future-focused plan will be a tool for digitalised decision-making. The tool will included a sophisticated database and analytical tools such as hydro-hydraulic modelling software.

An important feature to support the decision-making process will be the transparent and visualised information for all stakeholders.

New generation of engineers
Deputy Minister Vo Tuan Nhan and minister van Nieuwenhuizen officially launched the Climate Proof Vietnam programme that aims to train a new generation of engineers who are well equipped to protect their land against the water.

Over the next three years, two Dutch universities (Delft and Twente) and two Vietnamese universities (Hanoi and Thuy Loi) will support such training of Vietnamese water management professionals.

The education programme has a practical approach. For example, there will be a field lab where students can practice and test. There is also a lot of attention for high-tech applications such as drones.

115 years Nijhuis: More value for owners of waste water on a global scale https://www.dutchwatersector.com/news-events/news/36527-115-years-nijhuis-more-value-for-owners-of-waste-water-on-a-global-scale.html dws-nijhuis-jubileum-holterman1-770px"For the past ten years we have been focusing on waste-to-value. The coming ten years we want to focus on waste-to-wealth", said CEO Menno Holterman on the occasion of the celebration of the 115th anniversary of Dutch water technology company Nijhuis Industries. Holterman mentioned the growing demand for water, food, energy and nutrients for a world population that will reach 9.7 billion by 2050.

"As fresh water comes scares, treated waste water can be a potential water source, also for many of our industrial clients. It can be a factor of economic growth", told Holterman the guests that gathered from all over the world for the celebration. "Much of the value in waste water is left untapped". Nijhuis is operational in 130 countries and many of its waste water treatment projects involve the recovery of valuable resources, such as nutrients, fat and biogas. 

dws-nijhuis-115-years-wealth-350px According to CEO Menno Holterman 'waste-to-wealth' is Nijhuis' device for the next ten years.

Global leader in DAF-units
Nijhuis Industries started 115 years ago as a supplier of equipment for slaughter houses and specialised in waste water treatment for the meat industry. Today it is a leading global supplier of Dissolved Air Flotation (DAF)-units for many industrial sectors and municipalities.

On the occasion Nijhuis announced the agreement with Dutch slaughterhouse Esbro to recover all the fat from the waste water and convert it into biofuel. This will enable Esbro to heat up all its process water without using fossil fuels.

Growing tropical plants
One of the most striking projects presented on the anniversary was the Organica natural water treatment plant that Nijhuis is building in Russia at an IKEA shopping center. The installation has been started up a few days ago and is going to treat 1000 m3 of waste water per day. The purification is situated in a greenhouse building where tropical plants grow on the nutrients of the waste water. Visitors of the mall will be able to visit the greenhouse.

dws-nijhuis-115-years-semilla-scheer-350px Peter Scheer of Semilla explained how sanitary waste water can be converted into clean water and fertilizers. In the roll out of this technology, he is supported by Nijhuis.

Supporting innovative entrepreneurs
Over the years, Nijhuis has invested much in innovative water treatment technology that makes it possible to create value from waste water. The anniversary showed that the company wants to intensify their efforts on a global scale. Not only by building recovery plants with its own equipment, but also by supporting innovative entrepreneurs.

An example is Semilla Sanitation Hubs. Managing director of Semilla Peter Scheer was one of the speakers at the anniversary event. He told about the support he receives from Nijhuis to further develop and market his mobile toilet system.

A Semilla Sanitation Hub is currently being built in a refugee camp in Jordan where the effluent is used for irrigation.

Call for Blue-Green Infrastructure to balance water flows in Peruvian basins https://www.dutchwatersector.com/news-events/news/36493-call-for-blue-green-infrastructure-to-balance-water-flows-in-peruvian-basins.html dws-wetlands-peru-blue-green-infra-770px
"By using traditional water features such as high altitude wetlands and traditional irrigation channels, it may be possible to store more water upstream and have more water available downstream all year". AquaFondo and Wetlands International are studying the possibilities of combining nature and semi-natural structures for water management and risk reduction in the Peruvian basins. "Let us build the Blue-Green Infrastructure necessary to make Peru adaptable to the extremes of a changing climate and make sure all Peruvians benefit from the services these provide". Five Dutch and Peruvian experts made this call in a blog on the website of Wetlands International. They are studying the possibilities in Peru to create a more constant flow of water from the mountains throughout the year.

dws-wetlands-peru-blue-green-rimac-river350px-1  Swelling of the Rimac river, causing floods down stream.

Their suggestion is to use Peru’s high altitude wetlands (bofedales) that are situated 3,800 m above sea level. These wetlands have underlying peat layers that act as a sponge to retain and purify water in the upper section of the river basins. However, bofedales have been affected by human activities including overgrazing, metal mining and peat extraction.

Pre-Inca water engineering
Old pre-Inca irrigation channels, amunas (on top photo) allow communities to distribute and harvest this water. These amunas still exist high up in the Andean mountains, and they also facilitate superficial and underground water recharge, ensuring the availability of water throughout the year.

With more prolonged droughts caused by climate change, the amunas represent a lifeline for peasant populations in the highlands while also contributing to the water supply of dams downstream.

dws-wetlands-peru-bofedales-350px Management of the grazing is one of the measures to restore high Andean bofedales.

The potential of this Blue-Green Infrastructure is illustrated by the 135 km of amunas in the Chillón, Rimac and Lurin river basins that are within the scope of the expert organisation AquaFondo.

Beyond grey engineering
In their blog the experts argue that it is necessary to think beyond traditional or ‘grey’ engineering that channels rivers to protect the banks. This leads to faster discharge of excess water, increasing the risk of lower basin flooding. On the other hand, natural Blue-Green Infrastructure of floodplains can retard runoff due to their ability to temporarily store water (filling up and expanding the river); and lower the velocity of the river channel, thus controlling erosion.

This means that, instead of limiting the river, you must give it the space to grow and shrink, they advocate.

Ocean Cleanup assembles an updated prototype to resume plastic collection https://www.dutchwatersector.com/news-events/news/36448-ocean-cleanup-assembles-an-updated-prototype-to-resume-plastic-collection.html dws-ocean-clean-up-garbage-770pxThe Ocean Cleanup has conducted a root cause analyses of the failures of its first prototype that has been collecting plastic waste from the Great Pacific Garbage Patch late last year. The new insights will be used to rebuild the System 001 prototype that currently floats in a harbour in Hawaii. The rebuilding will take place on land, but the location has not yet been determined. The original prototype was built in San Fransico.

Wrong assumptions
It turns out that the team made wrong assumptions when it was building the first plastic catcher. As a result, the driver did not work properly. Welding seams were also broken when the floater was at sea. After analysing the data collected by the first catcher, the research team concluded that the plastic catcher moved less quickly than previously calculated. The team came up with 27 possible causes for this phenomenon. All of these were tested in the lab.

dws-ocean-cleanup-analysing-root-causes-350px   The research team came up with 27 possible root causes..

Different speeds
Using the collected data from System 001, the researchers calculated that they underestimated the power of currents and waves in the simulations. Apparently these two factors have so much effect that the difference in speed between the float and the plastic changed continuously. Sometimes the float went faster than the plastic, sometimes slower. As a result, the plastic never remained in the catcher for a long time. The connection between the screen and the tube had to endure too many forces, so that an 18-meter long piece of the barrier broke.

dws-ocean-clean-up-welding-350px Inspection learned that the weld between the floater and the screen had broken.

Weld connection
At the end of December, an 18-meter long piece of the 600-meter-long tube broke off. The prototype was towed to an Hawaii harbour and inspection has learned that the weld between the floater and the screen hanging under it had collapsed. This was probably due to excessive forces on the weld connection; the weld could not take it and broke.

Assembly of new prototype
Now that the causes are clear, The Ocean Cleanup reports the assembly of a new prototype that floats more resilient to wave forces. It will also probably reinforce the welds. As much parts of the original prototype will be used to assembly the new one. The team expects that it will take a few months, before the floater can be towed out again and resume its garbage collection again.

VolkerStevin appointed for framework of new assets Severn Trent Water, UK https://www.dutchwatersector.com/news-events/news/36434-volkerstevin-appointed-for-framework-of-new-assets-severn-trent-water-uk.html dws-volkerwessels-severn-trent-770px-1VolkerStevin has been appointed by UK’s water utility Severn Trent Water to deliver detailed designs and constructions of new water assets as part of the utility’s multi-year framework programme Asset Management Period (AMP) 7. The framework AMP7 is worth 2 billion UK pounds and involves many contractors that now have been announced. Severn Trent Water and the contractors will now start to define the key projects to be carried out between 2020 and 2025.

Continuous improvement
All UK water companies are following the AMP methodology to drive continuous improvement, and reduce their operating expenses (OPEX).

dws-volkerwessels-severn-trent-pumps-350px  For it's water works between 2020 and 2015 Severn Trent Water has announced ihe first contractors to join the AMP7 framework.

Since implementing the AMP methodology, with each period as a multi-year effort the current period is AMP6 (2015-2019), companies have seen clear strides in water quality improvement, and the latest focus is on Operational Expense (OP-X) reduction.

Severn Trent Water is the first UK utility to announce the contractors for the 7th AMP framework. For the new framework the utility has changed the way that it intends to carry out the work.

It says it will bring the design work in-house, including the creation of a new specialist design team, and will work with more construction contractors than previously – thus changing the way it intends to carry out the work between 2020 and 2025.

Outperforming efficiency targets
Rob Coupe, managing director at VolkerStevin, said: ‘We are looking forward to working with Severn Trent Water and bringing both our experience and expertise of working with other water utility companies; as well as across other sectors, where we have achieved industry leading customer experience, and have consistently outperformed against efficiency targets.’

Work is scheduled to begin in 2019, running through to 2024. Thanks to Severn Trent Water’s AMP7 Business Plan receiving fast-track status from water regulators Ofwat, Severn Trent Water are in a great position to begin their AMP7 investment, giving VolkerStevin, an early start on the planning stages.

VolkerWessels has been appointed in two parts of AMP7. In the part of Capital Delivery Design and Build the appointment concerns a joint venture with Atkins. In the other part of Civil engineering build-only, VolkerWessels was on its own.

Nijhuis improves existing wwtp of pharmaceutical company Biovet, Bulgaria https://www.dutchwatersector.com/news-events/news/36407-nijhuis-improves-existing-wwtp-of-pharmaceutical-company-biovet-bulgaria.html dws-nijhuis-biovet-existing-wwtp-770px-1
Nijhuis Industries has been chosen to optimise the existing waste water treatment plant at a factory of Biovet in Peshtera, Bulgaria.

Biovet is a manufacturer and marketer for farm animal productivity and health. A new production facility is currently under construction and will generate increased volumes of wastewater, which require treatment. Nijhuis redesigned the existing wwtp and has been chosen to construct and realize the optimization.

Optimised technologies
The current treatment plant was built in the 1980s, and cannot process the foreseen increased volumes of wastewater. On request Nijhuis redesigned the plant with introducing new water technologies. These optimised technologies have ensured that energy and chemical consumption have reduced considerably, and can being applied to smaller footprint systems with the help of a smart design.

Due to these developments, Nijhuis can reuse the existing concrete infrastructure, and retrofit newly installed technology equipment.

dws-nijhuis-biovet-dafcosmetics-plant-poland-350px  Nijhuis is very successful with the introduction of dissolve air flotation technologies for industrial waste water treatment. Here seen is a DAF unit at a cosmetics factory in Poland.

Nature-driven design
The new design has been inspired by the picturesque surrounding of the factory in a valley of the Rhodopi Mountains.

Gravity is used as far as possible. The wastewater will be pumped from the factory level in the valley floor, up to near the top of a hill.

With a height increase of 50 meters, the wwtp will be completely surrounded by the woods.

After the wastewater is pre-treated, a biological treatment system will use the power of nature’s gravity as a ‘cascade system’ and will automatically flow 50 meters down to the point where the water was originally pumped.

A new disolved air flotation (DAF) DAF system will be used as final polishing step. The factory is located in the town of Peshtera, Bulgaria, 120 km southeast of the country’s capital, Sofia.

Drinking water supply is up and running again in Beira, Mozambique https://www.dutchwatersector.com/news-events/news/36372-drinking-water-supply-is-up-and-running-again-in-beira-mozambique.html dws-idai-mozambique-wfl-repairs-770px
It took two emergency generators to get the drinking water supply of the city of Beira back into operation, following the failure of all electricity and communications when the devastating cyclone Idai hit the Mozambique harbour. Cyclone Idai made landfall in Beira on 15 March, with winds that brought huge rains and submerged villages as it moved inland towards Zimbabwe and Malawi. The official death toll has risen above 500 people and many people are still reported missing in Mozambique and Zimbabwe.

dws-idai-mozambique-ifrc-beira-devastation-350px The City of Beira is almost completely destroyed by cyclone Idai. (photo: IFRC)

Heavily hit
The city of Beira (300,000 inhabitants) has been affected heavily by the cyclone, approximately 90 per cent of the area is completely destroyed.

A production station, 60 km outside of the city was heavily damaged and generators had to be put in place to get the production working again.

Several Dutch water experts could assist in this emergency operation as they were already present in Mozambique as part of a support programme by the Dutch government to FIPAG, Mozambique's national water company.

“A miracle has happened“, says Wilco van der Wal, Resident Project Manager of Dutch consortium VEI in Beira. After seven days the drinking water supply for the city of Beira was up and running again with emergency generators.

According to Van der Wal the next step is to get the regular system working. "Together with FIPAG, we developed and rolled out a step-by-step plan to restore water intake from the source and to put the transport pipeline back into operation."

dws-idai-mozambique-wfl-repairs2-350px Pipe materials and fittings can be used that were already in place for a regular maintenance project by Dutch consortium VEI. (photo: Water for Life).

Broken pipelines
However, much is broken in the pipeline network. This is not only caused by Idai, but also by people who dig up pipes and break them in order to gain access to drinking water. With additional teams, VEI is working with FIPAG on public taps and the restoration of the pipeline network so that everyone can have access to drinking water again.

For these repair works, pipe material and fittings can be used that the VEI consortium had already put in place before cyclone Idai hit Beira for a regular repair work on the drinking water distribution network. 

The main concern at the moment is the outbreak of cholera that relates to the breakdown of sanitation and heavily polluted puddles that have remained in the city.

New research studies on health risks of microplastics: do plastics make us ill? https://www.dutchwatersector.com/news-events/news/36332-new-research-studies-on-health-risks-of-microplastics-do-plastics-make-us-ill.html dws-deltares-mictroplastics-770pxDutch organisation for health research and care innovation, ZonMw, launched fifteen research projects into the effects of micro and nanoplastics on our health. Water research institute Deltares is involved in four studies that focus on risks of the spreading of microplastics through water. One study will be on the microbial biofilm that forms on plastics and that may be a source of disease and infection. This is the first scientific programme in the world to tackle this health issue.

Possible health risks
Dick Vethaak of Deltares explains: "We are constantly exposed to small plastic particles through our food and drinks, or simply when we breathe. But it is still not easy to assess the implications for our health." According to Vethaak there are strong indications of possible health risks but there are also many uncertainties and knowledge gaps.

dws-deltares-biofilm-microplastics-scheme-350px   Microplastics (< 5 mm) in water may be colonialized with microorganisms that form a biofilm (source: Environmental Science & Technology Letters, 2017)

Biofilms on plastic and pathogens
Bas van der Zaan, water and health expert at Deltares, is working on an investigation of the health risks of microplastics that carry pathogens.

"Micro-organisms like bacteria and fungi can grow on plastics that end up in the environment", Van der Zaan explains. "It is very likely that these biofilms will also contain pathogenic bacteria."

The structure of biofilms on microplastics is highly dependent on the environment where these microplastics are located.

DNA techniques
Van der Zaan: "It is unclear which pathogens people are exposed to when they ingest microplastics through inhalation or ingestion, and whether this poses an additional risk to health."

To find answers these questions, clean microplastics will be suspended in various environments, such as ditches, purified sewage water. DNA techniques will be used to determine whether pathogenic micro-organisms nestle in the biofilms.

Deltares is working closely with the VU University of Amsterdam, Utrecht University Medical Centre and the New York Military Academy (USA) on this study.

Arcadis talks with Hong Kong authorities about land reclamation with polders https://www.dutchwatersector.com/news-events/news/36317-arcadis-talks-with-hong-kong-authorities-about-land-reclamation-with-polders.html dws-arcadis-hong-kong-polder-expansion-770pxInternational consultant Arcadis presented Hong Kong the option to create a polder as a mean to tackle the issue of land scarcity. Hong Kong wants to build a group of islands and considers the usual reclamation by infilling with sand.

Arcadis’ Global Leader for Water Management, Piet Dircke presented the Polder method at a recent stakeholders meeting and discussed the potential application in Hong Kong projects.

Islands in sea
Hong Kong needs to find land for the future housing of 1,1 million people. Last year, Chief Executive Carrie Lam unveiled the government’s ‘Lantau Tomorrow Vision’ which looks to create 1,700 hectares through reclamation.

Piet Dircke of Arcadis presented the polder method to the Hong Kong General Chamber of Commerce as a much cheaper alternative to create this new land.

dws-arcdis-hongkong-hkgcc-polder-dircke-350px  Piet Dircke of Arcadis addresses the stakeholders during a meeting at the Hong Kong General Chamber of Commerce (Photo: Hong Kong General Chamber of Commerce).

Less upfront construction costs
A polder is created by building a dike around the area to be reclaimed and draining water from it, creating a low-lying tract of land below sea level. The water levels in the polder are controlled by drains and pumps.

Compared to the traditional method of infilling with sand, this will reduce the amount of sand needed for reclamation and save on upfront construction costs.

In his presentation Dircke said: "There is huge opportunity for Hong Kong to consider alternative, more cost-effective and sustainable methods of land reclamation. I am excited to be sharing the Polder concept along with coastal resilience, a solution that can improve quality of life in Hong Kong for its citizens."

Understanding the risks of a polder
According to Arcadis the Hong Kong administration needs to understand that should it decide to construct a polder, it is important that the community has a full understanding of the potential risks and benefits.

dws-arcadis-hong-kong-map-lanta-350pxjpg Three islands (in red) planned on the south side of Lantou island.

As a Dutch consultancy, Arcadis has been involved with Polder developments for over a century, providing design and construction inputs to almost all polder projects in the Netherlands, as well as in other countries.

Hong Kong is no stranger to land reclamation with the first project undertaken by the British colonial authorities in 1851. Now around 6% of Hong Kong’s total area is reclaimed land, accommodating about 27% of the city’s population, and as much as 70% of Hong Kong’s commercial activities.

First polder in Singapore
Singapore is currently constructing its first polder to reclaim land on Pulau Tekong island. When the polder is completed around 2022, it will add an additional 810 hectares of new land to Singapore.

Dutch research institute Deltares and consultancy firm Royal HaskoningDHV have supported the Singapore authorities with an environmental study and an extensive review of the detailed design and contract documents.

World Water Day: Securing sustainable fresh water supply in coastal community Efoetsy, Madagascar https://www.dutchwatersector.com/news-events/news/36294-world-water-day-securing-sustainable-fresh-water-supply-in-coastal-community-efoetsy-madagascar.html dws-ewm-efoetsy-water-plant-700px
On the occasion of World Water Day, Elemental Water Makers released a story on impact of water scarcity on the inhabitants of Efoetsy, a village located on the dry south-western coast of Madagascar. In response, the Elemental Water Foundation, in partnership with Trans-Mad' Développement, the local community, Global Shapers - Amsterdam hub, Feedback Company and JCI Volcke Rack, will built a solar powered desalination plant. 

dws-ewm-efoetsy-pound-350px  One of the scarce fresh water resources for the Efoetsy community is this pond.

Impact of water scarcity
In many countries, communities are increasingly dependent on transporting water from far or applying expensive, energy-intensive water treatment to guarantee enough water for their population, a major challenge for less developed regions.

When Sid Vollebregt, water engineer and chairman of the Foundation Elemental Water Makers, was traveling in Madagascar, he saw the impact of water scarcity on local communities. He realized that the key to increased access to clean water must lie in the unlimited resources of the sun and sea. By conversion into freshwater (desalination), using solar energy, it is possible to solve freshwater scarcity in remote coastal areas in a sustainable and innovative way. This experience has become the origin of the Elemental Water Foundation.

dws-ewm-efoetsy-agriculture3-350px A desalination plant will break the cycle of water scarcity, providing the community enough fresh water to grow more crops, earning more money to improve their livelihoods.

First project location
Efoetsy was chosen as the first project location - and not without good reason. The remote village of Efoetsy is located on the dry south-western coast of Madagascar and receives less than 200 mm of rain per year.

The 3,000 people who live in and around the village live in extreme poverty and survive by farming, fishing and picking fruit and vegetables. However, this lifestyle is becoming increasingly difficult to maintain due to the decreasing availability of fresh water. Women and children spend up to 3 hours to provide water for their families.

The collected surface or groundwater is salty and polluted, leading to illness and school dropout. The only safe drinking water source is bottled water that is transported from far away to Efoetsy, which is often too expensive for the locals.

Sustainable water production
In cooperation with the local community of Efoetsy, the local NGO Trans-Mad' Développement is working hard to realize this drinking water project that will lead to 15,000 litres of clean and sustainable water produced per day in Efoetsy.

The solar-driven desalination solution will run entirely on the power of solar energy and trained local water entrepreneurs, who sell water at an affordable price and maintain the water installation.

Today is World Water Day and this year’s global theme is: Leaving on one behind. Leading up to today's event, the Dutch water sector met Yesterday in Amsterdam to explore the next steps that are needed to achieve the Sustainable Development Goal 6 on water by 2030.

In a debate joined by Dutch Minister of Foreign Affairs Sigrid Kaag, an expert panel focused on this year’s global theme Leaving no one behind.


 Dutch Minister of Foreign Affairs, Sigrid Kaag addressing the issue of leaving no one behind.

Water is about livelihoods
"Step out of your water silo. On this theme the human right agenda is overarching", Minister Kaag provoked the water professionals that were present. She emphasized that all SDGs speaks to a specific human right, water for all being only one of them. "Water is often left to the techies but it fits in with quality of life and livelihood."

Kaag gave the examples of separate latrines for girls. "It is often seen as a construction project, while the connections with the village, the drinking water, the health impact are never really thought through."

She highlighted the social aspects of the theme and challenged the water sector to act in an integrated matter. "Bring in your unique expertise that no one else has, to the overall landscape. You are coming from a technical field, so you bring something specific to make this happen".

"Water is critical", she continued. "Also in conflict prevention. In many areas with climate change it is the essential lifesaving, a live altering resource. If there is not sufficient water for all, in equitable and fair manner, future conflicts will be fought purely over water", she warned.

dws-wwd-altaf-mint Researcher Anika Altaf told about a disabled Ethiopian women she interviewed for her study and the attention alone brought this woman out of her exclusion by her own community.

Hidden faces 
"Are we reaching the extreme poor and margalised people?, asked researcher Anika Altaf of the University of Amsterdam. ‘They are not reached by development interventions. That is the conclusion of my research on a number of case studies.’

In January, Altaf promoted her study The many hidden faces of extreme poverty. Inclusion and exclusion of extreme poor people in development interventions in Bangladesh, Benin and Ethiopia.

"These people seem to be invisible", she told. "Even within their own communities. They tend to self-exclude, making it even harder to development agencies to reach them". 

Altaf advised the water sector to set out on a long term effort, based on local knowledge. "Everybody is focused on numbers, in money or material terms. But that is not what extreme poverty means to people. What matters most to them is a sense of humanity. Being loved and treated with dignity, matters most to these people."


Get the full picture first
Minister Kaag underpinned this finding and advised the water sector to: "dig in deep for equity. Always be focused on the human right agenda. Assess your water measure as part of the full picture and if things are wrong, address it". 

Kaag advocated a practical mix of this long term intervention with every day’s reality. "People that need water, have no time for our long term agenda, so we have to be mindful on what we try to achieve on the short term as well."

Overlooking the Bristol Channel, Stolford has a history of coastal erosion and is prone to flooding. In 1981 high tides overtopped sea defences and flooded 660 hectares of land including 24 properties. Livestock also died. In 1990 a high tide and storms caused further flooding.

There are already coastal defences between Stolford and Hinkley comprising of rock armour and an embankment wall. These defences adjoin a shingle ridge that was prone to serious erosion.

Beach replenishing
Rising sea levels and more extreme weather conditions have made the ridge and embankment increasingly vulnerable to erosion and increased the risk of a breach.

The Environment Agency previously spent 50,000 UK pounds a year replenishing the ridge with 15,000 tonnes of shingle.

Conventional rock armour, also known as rock revetment, would have been too costly and visually intrusive. In addition, the transportation of rock armour would have caused excessive disturbance from heavy lorries travelling in narrow lanes to a remote coastal location.

Reducing wave run-up
The Environment Agency decided the best solution was to construct a revetment with the Dutch system known as Hillblock that uses a series of specially-shaped concrete blocks.

John Curtin, Executive Director of Flood and Coastal Risk Management at the Environment Agency, said: "This is an exciting engineering first for UK – the new technology installed at Stolford can reduce wave energy by up to 30 per cent compared to the shore protection traditionally used."

"It will provide valuable protection to this Somerset community and the surrounding agricultural land", Curtin added.

The revetment has been constructed by Team Van Oord, a Joint Venture partnership between Van Oord, Kier, Mackley and Royal HaskoningDHV .

Election fever: politicians debate water issues in the Netherlands https://www.dutchwatersector.com/news-events/news/36148-election-fever-politicians-debate-water-issues-in-the-netherlands.html dws-ihe-delft-debate-panel-770pxTomorrow, on 20 March, the election of regional water authorities will take place in the Netherlands. Every four years Dutch citizens can vote for candidates for one of the 21 regional water authorities that are responsible for managing water levels, waterway maintenance, and water quality.

In a country where half of the land is situated below sea level – and cities are kept artificially dry with levees, canals, and pumping stations – maintaining water levels is a big deal. Especially now the climate change is leading to more extreme weather events, both in sense of longer dry periods with too little water as well as more cloud bursts with too much water.

In all 21 districts candidates for the water boards debated their different views on managing all water-related issues in their specific district.

dws-ihe-delft-debate-student2-350px  A Mexican IHE-student asked how well Dutch regional water authorities are integrated in the general governmental structures as all regional water policies and measures are developed by local water authorities.

Political debate for students and expats
One of these debates stood out, as it was in English. On 15 March, the water education institute IHE Delft organised a debate (on top photo) for their international students and the local expat community, who, as residents of regional water authority Delfland, can also vote tomorrow on their candidates.

Some hundred students attended the debate and could hear five candidates argue about many different water issues. Two candidates represented a specific water party (Algemene Waterschapspartij and Water Natuurlijk) and the other three candidates represented traditional national political parties (VVD-liberals, CDA-Christian democrats and PvdA-social democrates).

It is often said in Dutch regional water authority elections that a levee is not a left- nor a right-winged solution. There is nothing political about a levee. However, it is possible to debate about the timing of the strengthening of it, or provide additional funding for a cycle path so tax payers can also enjoy the levee.

dws-ihe-delft-debate-logo-vote250pxHighest tax rates
It was no surprise that the five candidates agreed on many issues. Until the question arose who should pay the bill. Delfland is with its annual tax of 450 euro by far the most expensive regional water authority in the Netherlands. The water authority is very densely populated leading to a very expansive water infrastructure. It also has to drain many deep polders and prevent the seepage of silt groundwater.

The high water tax is a big issue for low income people and the many students that live in the district. Hans Middendorp of the Algemene Waterschapspartij therefore advocated a more fair taxes system that allows people with a low income to pay less taxes.

Land subsidence in polders
Delfland is situated along the coast and faces sea level rise. But at the same time it faces land subsidence as the peat in its polders oxidates. The debate on this issue revealed a political opposition. Marcel Belt (Water Natuurlijk) wants his water authority to raise the water levels in those peat lands to stop the subsidence – and the emission of CO2. However, as he plead, this should be done in consultation with local farmers that need dry land to run their businesses. Therefore the water authority is currently keeping the water levels low in the polders.

dws-ihe-delft-debate-five-candidates-350px  Five candidates for the Delfland regional water authority elections: (f.l.t.r.) Hans Middendorp (AWP), Maarten Jansen (CDA - Christian democrats) ), Leon Hombergen (PvdA - social democrats), Peter Ouwendijk (VVD - liberal), Marcel Belt (Water Natuurlijk) (all photos: IHE Delft/Hans de Lijser)

"The time for mono functions is over. Land in the Netherlands is too scarce for that. We have to look for multifunctionality in which agriculture and biodiversity go together", said Belt.

Maarten Jansen (CDA) opposed and told not to believe in compromises. "If there are farmers in an area, look for an overall solution. Do not raise the water level if there is a small nature area near a farming area. Look at the main function of an area as a whole", Jansen said.

Medicine residues
A striking disagreement emerged in the debate on the removal of medicine residues from municipal waste water. Hans Middendorp (AWP) was in favour, but Leon Hombergen (PvdA) did not understand why AWP recently voted against the expansion of a waste water treatment plant with an additional treatment step.

Middendorp explained to have voted against because his party considered the investment an inefficient use of tax payers money. "Only a quarter of the effluent is additionally treated and the discharge point is located very close to the sea", he explained. "We are in favour of additional treatment at real hotspots. At waste water treatment plants where the removal of such medicine residues makes much more sense and contribute more to cleaner surface waters."

HydroNET completes control room for all nine South African water management areas https://www.dutchwatersector.com/news-events/news/36140-hydronet-completes-control-room-for-all-nine-south-african-water-management-areas.html dws-hydronet-south-africa-rainwatch2-770px-1South African Department of Water and Sanitation (DWS) recently launched its HydroNET Water Control Room at a festive ceremony in Pretoria.

All nine of the country’s Water Management Areas now have access to the weather and water information they need to make weather‐ready and climate‐smart decisions for sustainably managing precious water resources.

The HydroNET Water Control Room has been developed and delivered by consultancy firm Hydrologic, ICT-firm eLEAF and South African Weather Service.

HydroNET is a web‐based decision‐support system for operational and strategic water management. It combines weather information from the South African Weather Service (SAWS) with water information from the Department of Water and Sanitation (DWS).

It also adds models and local knowledge to generate personalised overviews, forecasts and warnings.

This information is available via dashboards and reports.

Weather information
Last week, over 150 South African water managers were trained to optimally benefit from the SAWS information, which is easily accessible via HydroNET.

Information on irrigated water use, water availability, water quality and other relevant data will be connected to HydroNET in the next few months, and more training sessions will be organised.

Every raindrop counts
South Africa suffers from water stress. To efficiently manage the available water resources and reduce climate‐ and weather‐related impacts, water managers need access to historical, current and forecast water and weather information.

As Leanne Reichard, Business Director of HydroNET, comments, ‘I’m extremely proud that over 300 South African and Dutch colleagues have been able to work together to provide South African water managers with a practical solution that supports them before, during and after weather‐ and climate‐related events.’

Reichard continues: ‘I’m pleased to see, for example, that the water auditing application developed in South Africa to monitor irrigated water use is now also going to be implemented in the Netherlands to support Dutch water managers during droughts. This way, Dutch water management will also benefit substantially from our success in South Africa.’

AIWW Conference 2019: Call for cases that illustrate new value chains in water sector https://www.dutchwatersector.com/news-events/news/36116-aiww-conference-2019-call-for-cases-that-illustrate-new-value-chains-in-water-sector.html dws-aiww2019-call-cases-table-map-770px-1
"A new strongly interdependent market structure is emerging in which water utilities, cities, industries, energy and agrifood sectors, urban developers and financiers, each acting, enter into new relationships to forge the value chain for water", says Kees van der Lugt, programme director of the Amsterdam International Water Week.

The next edition will take place in November and Van der Lugt invites the world to submit interesting cases that can be programmed for the AIWW Conference. Deadline for submission is 29 March 2019.

dws-aiww2019-call-cases-lugt-350px Programme director Kees van der Lugt at the AIWW Summit last November where the topics were discussed for the next AIWW that will take place later this year.

Collaboration and bankable projects
According to Van der Lugt new relationships are needed to forge the value chain of water. "Partners need each other for the implementation of sustainable solutions. For example, a water company can generate energy from water, but marketing the energy is not their core business. They will stand stronger if they work with an energy company and commercial partners."

As programme director he hopes to present cases at the conference that illustrate this change and especially, be able to discuss the gains and setbacks.

Be part of the solution
Van der Lugt marks the unique opportunity to become part of the solution. "Inspire us, join us in matching best practices to the water challenges we are facing worldwide. We offer the platform to make connections during the AIWW Conference". 

As there can be no true innovation without implementation, the programme director finds it interesting to use these cases to explore sound business models and the ability to attract financial institutions – development banks and commercial banks.

dws-aiww2019-call-case-round-table-350px AIWW Conference is much about actively engaging and sharing insides and experiences.

Four inspiring themes
The conference call for content for abstracts, workshops and cases or solutions focuses on four themes:
● energy transition and resource recovery
calls for circular business models to open the way to incorporate multiple principles for value creation. Advanced integrated solutions to complex challenges are needed to create impact.
● integrating water and resource management
focuses on the need for increased cooperation among resource user groups to balance the economic, environmental and social needs of society.
● IT & data: artificial intelligence and smart robotics
We are convinced that new IT and data solutions can be a game changer in water management and are key to keep our infrastructure resilient and secure.
● blue-green solutions for urban resilience
all about creating resilient communities and critical infrastructure. This asks for continued collaboration and innovative solutions.

Come to Amsterdam and join AIWW
The AIWW Conference is organised by Netherlands Water Partnership and IWC Conferences, and is supported by the Dutch Government. 

Besides the AIWW Conference itself, the Amsterdam International Water Week includes the Aquatech Amsterdam, Sarphati Sanitation Awards, the Young Professionals Programme and excursions.

IRC 50 years: A serious attempt to achieve universal access by 2030 https://www.dutchwatersector.com/news-events/news/36079-irc-50-years-a-serious-attempt-to-achieve-universal-access-by-2030.html dws-irc50-hema-banfora2-770px"When we talk here about WASH-systems, we are not only talking about pipes, pumps and toilets. We are talking about people", said CEO Patrick Moriarty at the opening of the jubilee symposium of his foundation that celebrates its 50th anniversary.

Moriarty explained the importance of strengthening the service delivery of WASH-systems in a wider sense than just building its infrastructure. Improvement of service delivery goes beyond business as usual Moriarty said, and are essential to reach universal access to water and sanitation by 2030.

dws-irc50-opening-moriarty2-400px CEO Patrick Moriarty opened the jubilee symposium on wash systems to achieve universal access to water and sanitation in 2030 for everyone.

The jubilee symposium takes place from 12 – 14 March in the Hague, the Netherlands. The title ‘All systems go’ refers to the corner stone of IRC’s current activities to engage local stakeholders in district level WASH planning.

One such district plan concerns Banfora in south west Burkina Faso. At the symposium Richard Bassono if IRC Wash highlighted the first findings (on top photo).

Complexity of livelihood
Moriarty told about the history of IRC Wash and the discovery by his organisation how difficult it is to implement water projects in developing countries that last. As a young civil engineer he discovered the complexity of rural livelihood and development in Zimbabwe.

He praised the inspiring local civil servants, he met in those days. "We often overlook those people. They are underpaid, under appreciated in the broader development narrative. People that, in my mind, are always dedicated to the community they serve. They are the back bones of the water and sanitation systems".


Barbara Schreiner, director at Water Integrity Network addressed the 'shadow system' of corruption that is paralysing so many good intentions.

Many interacting systems
For IRC Wash it was an obvious step to decentralise the office in the Netherlands and start offices in various developing countries, headed by those local wash people. In Uganda, Ghana and Burkina Faso, IRC’s local offices are assisting the ‘local civil servant champions’ to set up long term masterplans to achieve universal access on a district level.

"We want to move beyond our comfort zone as sector technocrats and build strong wash systems based on social, political and economic involvement", Moriarty said. To reach full access to wash services, all systems need to be addressed in order to make the service delivery possible to everybody, Moriarty concluded.

Royal Boskalis contracted to widen channel for Adelaide port, Australia https://www.dutchwatersector.com/news-events/news/36072-royal-boskalis-contracted-to-widen-channel-for-adelaide-port-australia.html dws-boskalis-adelaide-tshd-gateway-770px-1Royal Boskalis has been awarded a contract for the widening of the shipping channel of the Port Adelaide Outer Harbor in Australia. The project was awarded by port owner and operator Flinders Ports. The contract carries a total value of 40 million euro.

Larger ships
Boskalis has been appointed to widen the shipping channel to 170 meters from the current 130 meters, and extend the turning basin to accommodate the larger and more efficient Post Panamax container ships which are increasingly dominating global containerized cargo transport. 

dws-boskalis-adelaide-inner-harbour-450px   Port Adelaide’s Inner Harbour berths (Flinders Ports)

The expanded channel will also accommodate larger cruise ships to support a stronger tourism industry.

An estimated amount of 1.5 million cubic meters of mainly sand and clay material will be removed with a trailing suction hopper dredger and a large backhoe dredger.

Strict environmental requirements
Flinders Ports and Boskalis are committed to minimizing the environmental impact of the channel widening program and maximizing the ongoing health of the marine environment in line with the strict requirements of the Environment Protection Authority dredging license.

The dredged material will be placed in a designated area 30 kilometers offshore with the aid of adaptive environmental management techniques to ensure that the maximum permitted turbidity levels are not exceeded. The project will be executed in the second half of 2019.

Masaai women make money by selling seeds from newly dug bunds in Kuku, Kenya https://www.dutchwatersector.com/news-events/news/36045-masaai-women-make-money-by-selling-seeds-from-newly-dug-bunds-in-kuku-kenya.html dws-justdiggit-masai-seeds2-770px-1The grass will look green… when collaborating with a women’s group. The Maasai women in Kuku, Kenya, are working hard maintaining and continuously improving the grass seed banks. Foundation JustDiggit shared this message at International Women’s Day on 8 March.

dws-justdiggit-masai-women-seasons-400px By digging bunds in the gorund, it is possible to catch the rainwater and make vegetation grow in dried up areas, like in Kuku, Kenya.

Return of vegetation
JustDiggit works with local teams in several African countries on large scale landscape restoration projects, retaining rainwater for vegetation and preventing erosion, flooding and land degradation.

One of their projects is in Kuku, Kenya, where 72,000 half-moon pits have been dug in the dried up grounds (bunds). These bunds catch the rainwater so vegetation returns.

Selling grass seeds
The Masaai women harvested grass seeds and used it partly to grow new grass in the bunds. Another part of the seeds was sold, meaning income for the women.

JustDiggit expects that if the women sell even more seeds in the future, they will create a sustainable market and will take advantage of the growing economic value.

dws-justdiggit-bee-hives-350px By selling grass seeds, the Massai women made money to buy bee hives that polinated the grass and stimulated the re-greening process.

To bee!
The women of the Enkii group bought three bee-hives with the money earned from placing the fences around the grass seed bank.

These hives are standing in the middle of the grass seed bank. Smart, since the bees can pollinate the grass which enhances the re-greening process.

The women have been trained in how to maintain these bee-hives and how they can harvest the honey. By selling the honey they create an extra income.

Keeping out elephants
The women are also looking into the possibility of using bee-hives for deterring the elephants from entering the grass seed banks. Elephants are terrified of bees. This prevents crushing of the grasses, increasing the harvest of the grass seeds.

These activities help women to become more independent and enables them to have their own livelihood. Additionally, they can use the money for paying school fees, health care and food for their family.

dws-nijhuis-fairbanks-impression-csd-350px  Impression of the heavy-duty rock cutter suction dredgers under construction by Royal IHC.

Dredging in hard ground
Ship builder Royal IHC recently received an order from the Suez Canal Authority (SCA) for the supply of two cutter suction dredgers. These dredgers, which will be used to deepen and maintain the Suez Canal in Egypt, have been specially developed for dredging in hard ground.

"The design for these new vessels is based on a cutter suction dredger previously built by IHC, for which we delivered thirty pump sets almost 25 years ago," said Henk Jan van Essen, Senior Area Sales Manager at Pentair.

Split-case pumps
"After all these years, the performance and reliability of these pumps is still very good", Van Essen continued. "As a result, we were immediately contacted for this assignment. Another important reason why the end customer specifically chose for our product is that we are one of the few pump manufacturers in the world that has a large range of split case pumps."

Each dredger will be equipped with 51 pump sets that range from a variety of Pentair Fairbanks Nijhuis pump models to address specific needs of the project. The pump sets will be supplied with different models, ranging from VGT, HG1, HG2 and Venus.

Nijhuis designs Bioctor treatment plant for cider producer Cornish Orchards, UK https://www.dutchwatersector.com/news-events/news/36015-nijhuis-designs-bioctor-treatment-plant-for-cider-producer-cornish-orchards-uk.html dws-nijhuis-cornish-orchards-cider-production-770px-1Nijhuis industries designed a Bioctor sequence batch reactor for the treatment of the waste water of cider producer Cornish Orchards, UK.

The Bioctor contributes to Cornish Orchards’ aim to reduce the volume of its waste water. The renewed waste water treatment will allow the cider producer to commission a treatment plant based upon smart and sustainable principles, all realised on small footprint.

Nijhuis Industries designed the new Bioctor installation, as part of a turnkey design and build solution.

dws-nijhuis-cornish-orchards-bioctor-350px   Nijhuis’ Bioctor technology is based on a moving bed bioreactor (MBBR) using carrier material which results in a more effective growth of bacteria, allowing a compacter aeration.

Two screens
The design prises of the pumping of effluent from an existing wet well to a rotating screen with scraper to remove bottle caps, labels and other large obstructions. This feeds into a cloth screen incorporating polymer dosing to remove high levels of total suspended solids such as pumice from apple pressing. The screened effluent is then introduced to a Nijhuis Bioctor-SBR tank via a selector tank.

Sequence batch reactor
The Bioctor process is a single batch bio treater comprising a 465m2 tank with floating aerator and decanting arm. The biomass within the tank converts organic matter to water, carbon dioxide and new biomass with the aid of oxygen induced by the aerator.

Oxygen levels are monitored and controlled by an in-line probe.

The excess sludge from the Bioctor-SBR tank is fed back to the cloth screen to thicken the sludge and thereafter to a sludge storage tank.

dws-nijhuis-cornish-orchards-bioctor-aeration-350px Aerators in the MBBR-tank.

Reduced visual impact
The tank and associated equipment, pumps and transfer tanks are to be accommodated within a cast in-situ reinforced concrete bunded area.

This reduced the visual impact of the plant which is set within a 16th century farm. The difference in level between the lower bunded area and the upper slab allowed gravitational flow from the screens situated at the upper level.

The whole process is controlled by the Nijhuis PLC electrical control panel housed in a bespoke control room, which also provides housing for chemical/polymer dosing and sampling facilities.

Buffering capacity
Treated effluent is pumped 75m up to the client’s existing old treatment lagoons. These lagoons were adapted to provide buffering capacity of batched effluent by the inclusion of a hydro brake to limit flows to the maximum discharge consent specified by the Environment Agency. Flows from the hydro brake are fed via a 200m sewer to discharge into the local stream.

Preferred bidder for new wwtp at Jeddah airport includes Nereda technology https://www.dutchwatersector.com/news-events/news/35966-preferred-bidder-for-new-wwtp-at-jeddah-airport-includes-nereda-technology.html dws-rhdhv-jeddah-airport-expansion-dep2-740px-1
A consortium led by water firm Marafiq signed a contract with the Water and Electricity Company (WEC) for the construction of a new waste water treatment plant for the expansion of Jeddah airport, Saudi Arabia.

The consortium has been appointed as preferred bidder for the stage 1 construction of the wwtp to treat 300,000 m3 per day starting in late 2021. The treatment plant is to include Nereda technology that purifies water using distinctive features of aerobic granular biomass in a sequence batch reactor. The contract was signed on 25 February.


 Signing of the contract by WEC and the consortium led by Marafiq.

New terminal
Jeddah airport is currently being expanded with a new terminal that is expected to become operational later this year.

The terminal will have a new waste water treatment plant that will eventually have a capacity of 500,000 cubic meter per day, said a statement from Saudi Arabia's Water and Electricity Company (WEC).

The Jeddah Airport 2 STWP project will be developed under a 25-year sewage treatment agreement (STA), under which the sewage capacity will be provided by the National Water Company (NWC).

As per the deal, the consortium will be responsible for the development, financing, engineering, procurement, construction, implementation, ownership, operation, maintenance and transfer of the plant.

Construction of the new wwtp is expected to start in Q2 2019 and will be built over two stages. Stage one will treat 300,000 m3 per day starting in late 2021 and stage two will add another 200,000 m3 per day.

dws-rhdhv-jeddah-wwtp-utrecht-350px The biggest Nereda plant is currently under construction at wwtp Utrecht, the Netherlands. It is expected to be commissioned this summer and will have a capacity of 317,000 m3 per day.

Lowest water rates
Minister of Environment, Water and Agriculture, and Chairman of the Board of WEC, Eng. Abdulrahman Al Fadli, praised the standards set by the project. "We are very pleased that the consortium led by Marafiq is bringing us a cost-effective solution with one of the lowest sewage tariffs ever recorded."

Al Fadli: "This is the Kingdom’s second STP offered on a build, own, operate and transfer basis and we expect to see more of these type of projects as part of the Kingdom’s 2030 Vision."

Once commissioned, the wwtp will be the second plant in the Kingdom that results in only beneficial sludge being produced, while at the same time producing re-cycled water that will be sold to NWC for further use in agriculture and commercial applications.

The Water and Electricity Company is fully owned by the Ministry of Finance of the Kingdom of Saudi Arabia and is the sole procurer for water related projects procured through the private sector in the Kingdom.

About Nereda
Nereda is a waste water treatment technology that has a small footprint requiring a quarter of the area of conventional activated sludge installations. It is also energy efficient and can reduce up to 50 percent on energy-costs. The award-winning technology was invented by the Delft University of Technology in the Netherlands and developed in a unique public-private partnership between the University of Delft, the Dutch Foundation for Applied Water Research (STOWA), the Dutch Water Authorities and Royal HaskoningDHV.

Chinese dredger Hang Jun 6008 completed sea trials in Yangtze estuary https://www.dutchwatersector.com/news-events/news/35954-chinese-dredger-hang-jun-6008-completed-sea-trials-in-yangtze-estuary.html dws-ihc-tshd-hang-jun-6008-sea-trail-770pxNew 6,500 m3 trailing suction hopper dredger (TSHD) Hang Jun 6008 has successfully completed sea trials in the area outside the Yangtze Estuary in China. 

The new dredger left the Shanghai Zhenhua Heavy Industry Co., Ltd. (ZPMC) shipyard last August. Basic engineering and dredging automation systems for the vessels have been supplied by Royal IHC in the Netherlands.

Hang Jun 6008 is the first of the two 6500 m3 TSHD’s for IHC's customer China Harbor Engineering Company (CHEC), a subsidiary of CCCC Shanghai Dredging Company. The second TSHD, the Hang Jun 6009, will go on sea trials this March.

In cooperation with Royal IHC
The realisation of the two vessels takes place in cooperation with Royal IHC from The Netherlands.

IHC has carried out the design and the basic engineering, but it also delivers equipment packages consisting of the entire dredging installation, the electric systems and the dredging automation system, including the control system for one-man operation.

The project is managed by CCCC Mechanical & Electrical Engineering Company.

Maintenance and capital dredging
After their completion, the dredgers are scheduled to carry out both maintenance as well as capital dredging works, amongst other in the Yangtze Estuary channel and for the Shanghai International Shipping Center and the Shanghai Free Trade Zone.

Future deployment is also expected in other countries in Asia.

WasteShark makes its UK debut clearing Ilfracombe harbour of plastics https://www.dutchwatersector.com/news-events/news/35936-wasteshark-makes-its-uk-debut-clearing-ilfracombe-harbour-of-plastics.html dws-ranmarine-watershark-740px-1
World Wildlife Fund and Sky Ocean Rescue launched the marine robot WasteShark for the first time in the UK. In the harbour of Ilfracombe the WasteShark cleared the harbour of floating plastics and other waste on 3 March. The robot can operate autonomous for 8 hours on a rechargeable battery, with the capacity to collect over 15 tonnes of waste per year.

The WasteShark is created by RanMarine Technology, specifically to eat waste and collect data.

dws-ranmarine-watershark-ilfacombe-350px  First time for the marine robot WasteShark to operate in the United Kingdom.

Marine protected area
Ilfracombe Harbour is within a marine protected area that is home to diverse species. It boasts some of UK’s most diverse wildlife - including grey seals and pink sea fan corals.

Collecting waste in the harbour prevents damage to the immediate area and from plastics being taken out to sea by the tide and threatening the important wildlife in surrounding MPAs.

UK’s first
It is the first time that a WasteShark has been used in the UK, following successful launches in five countries, including South Africa, Dubai and the Netherlands.

The WasteShark is designed to be harmonious with the environment. As it navigates the water the WasteShark emits no carbon, produces no noise or light pollution, and poses no threat to wildlife.
