Projects

In Westland, on the outskirts of The Hague, new construction location ‘Het Nieuwe Water’ is taking shape: a progressive project with over 1,200 homes. What makes this project unique is the link between the houses and the surrounding greenhouse horticulture. Here, waste water is not seen as a residual flow, but as a valuable source for reuse. The houses will be equipped with a decentralised sanitation system, where grey and black wastewater are collected and treated separately. After treatment, the treated water - together with recovered fertilisers - is used in cultivation within the greenhouses. The result is a virtually closed water cycle in which domestic wastewater serves again as a raw material. Eventually, even drinking water is recovered from the system. In doing so, this project makes a concrete contribution to circular area development and innovative water reuse.

We also carried out a thorough feasibility study that brought together technology, logistics and spatial integration. We also provided substantive support for the social cost-benefit analysis (SCBA), which revealed the added value of this circular approach.

In Simferopol, near the Black Sea, Desah collaborated on a future-proof solution for wastewater treatment. An innovative extension was realised within a large sports complex, which, among other things, houses 188 pupils. This expansion doubles the capacity of the boarding school, which calls for a robust and sustainable wastewater treatment plant. Simferopol's location on the Black Sea places additional demands on the environmental impact of wastewater. This water body, due to its limited flow, is extremely susceptible to eutrophication - a process where excess nutrients lead to decline in biodiversity. By focusing on circular and local treatment of wastewater, the impact on this fragile ecosystem is minimised.

This separation allows both water streams to be treated more effectively and sustainably, while retaining valuable nutrients and energy. Prior to the project, Desah conducted a feasibility study after which and process and detail design was made. Ultimately, the project was realised on the basis of these preliminary studies.

The Netherlands Institute of Ecology (NIOO-KNAW) in Wageningen is known as one of the most sustainable research buildings in the Netherlands. From the beginning, one goal was central: to realise an integrally sustainable building, in which the sanitation system also contributes to energy and recycling goals. In this project, Desah provided a decentralised sanitation solution in which black and grey water are collected separately and processed locally. This forms the basis for growing algae, which in turn serve as raw material for a combined heat and power (CHP) plant. This creates a closed cycle of water, energy and nutrients within the building itself. This innovative design shows that sustainable building goes beyond insulation and solar panels. The wastewater system can also be a source of valuable raw materials as well as energy.

Floriade is the world horticultural expo that takes place in the Netherlands only once every ten years. In 2012, this sixth edition took place in Venlo and attracted no less than two million visitors. The central theme was one that is also in Desah's DNA: sustainability. A pioneering concept for circular energy and water flows was realised in the Villa Flora utility building. Separate collection and decentralised treatment of waste water was chosen for Villa Flora. Toilets on the site are connected to a vacuum system that ferments black wastewater together with organic waste. The remaining grey water - such as from sinks - is treated separately with a helophyte filter. This approach minimises water consumption and maximises resource reuse.

Our contribution included a feasibility study together with a process and detailed design of the system. This eventually resulted in the delivery of the entire system. Thanks to this approach, the system not only delivers cleaner water, but also energy and valuable nutrients back to the environment. The project at Floriade serves as inspiration for circular neighbourhood concepts, sustainable offices and recreational areas. With this case, Desah underlines how decentralised systems are a practical and scalable solution for sustainable water management.

A complete redevelopment took place in the Noorderhoek residential area in Sneek: 282 outdated houses made way for 232 new, future-proof homes. This large-scale restructuring project provided a unique opportunity to use circular technologies for sustainable water management. An integrated energy and water concept was chosen within the ‘Waterschoon’ project. In cooperation with various parties, Desah delivered an innovative decentralised sanitation system that treats black and grey water separately. This made Noorderhoek the first residential area worldwide where this separation and treatment was successfully applied at neighbourhood level. The installation in Sneek now serves as a showcase for visitors from home and abroad interested in circular water concepts.

The plant includes a digester for black water and food waste, which generates biogas. At the same time, nitrogen is efficiently removed from black water, and valuable struvite is recovered; a fertiliser that can be reused in agriculture. Grey water is also treated in the district. Energy is saved via heat recovery from greywater, while biological treatment ensures concentrated treatment to high-quality effluent. The entire system is equipped with an advanced control and automation system, ensuring stable operation and easy management. Desah was responsible for the complete start-up of the system, and also provides management and maintenance, ensuring that the installation continues to operate sustainably and efficiently.

In 2016, Canadian project developer Belrose Farms, in collaboration with the University of Alberta, initiated a full-scale demonstration project with our innovative wastewater concept. The aim of this project was to demonstrate that a decentralised wastewater treatment system is a technically, economically and environmentally valuable alternative to conventional sewage and treatment methods in Canada.

The system is designed to generate renewable energy in the form of biogas and recover valuable nutrients for reuse. The smart design of the system also significantly reduces drinking water consumption within the district. In the new residential area, which will eventually have a population of about 1,500 and is located on the Sturgeon River near Edmonton, wastewater is collected and treated completely separately. The black water, from toilets, will be treated in a concentrated manner, creating optimal conditions for biogas production and efficient resource recovery. The grey water, from showers, kitchens and washing machines, among others, is purified via a separate route so that it can be reused on site or discharged safely.

In cooperation with Antonius Hospital, Desah developed the first-ever demonstration site for the treatment of hospital wastewater. This unique site in Sneek provides a valuable testing ground for testing and improving sustainable purification techniques. Waste water from various hospital departments is fed to this site. Companies can further develop and perfect their technologies here. The demo site is equipped with all necessary facilities. This is a 5-year pilot project. A first for the Netherlands and Europe #ms-container-5d720b2.has-background:before { background-color: transparent; } @media screen and (max-width: 39.9375em) { #ms-container-5d720b2 { padding-top: 1rem; padding-bottom: 1rem; } } @media screen and (min-width: 40em) and (max-width: 63.9375em) { #ms-container-5d720b2 { padding-top: 2rem; padding-bottom: 2rem; } } @media screen and (min-width: 64em) { #ms-container-5d720b2 { padding-top: 2rem; padding-bottom: 2rem; } } Location:Sneek Client:Antonius ZH in cooperation with Wetsus Market:Decentralised wastewater treatment Year of completion:2014 #ms-container-d98a29d.has-background:before { background-color:transparent; } #ms-container-e16b8be.has-background:before { background-color: #E8F3FF; } @media screen and (max-width: 39.9375em) { #ms-container-e16b8be { margin-bottom: 1rem; padding-top: 1.5rem; padding-bottom: 1.5rem; } } @media screen and (min-width: 40em) and (max-width: 63.9375em) { #ms-container-e16b8be { margin-bottom: 2rem; padding-top: 3rem; padding-bottom: 3rem; } } @media screen and (min-width: 64em) { #ms-container-e16b8be { margin-bottom: 2rem; padding-top: 3rem; padding-bottom: 3rem; } } At the demo site, three water streams are collected and treated separately. First, it is the total hospital wastewater. For existing hospitals, it is often difficult to separate wastewater streams per department, making treatment of the entire wastewater stream an obvious solution. In addition, specific toilet water is collected from departments with high use of antibiotics and cytostatics. By collecting this wastewater directly at source, medicine residues can be removed more effectively; a relevant approach for hospitals with new construction or renovation plans. Finally, wastewater from separating toilets on certain wards is also collected separately. Here, urine and faeces are collected separately, so that targeted processing of, for example, nutrients such as nitrogen and phosphate can also be investigated.

One of the most advanced decentralised wastewater treatment plants in the Netherlands has been realised in the New Government Offices at Rijnstraat 8 in The Hague. More and more organisations no longer regard waste water as a residual product, but as a valuable source of energy and nutrients. This project is a leading example of how circular sanitation can be applied in large office buildings. The new accommodation for about 6,000 civil servants is equipped with an innovative installation that processes wastewater locally and recovers valuable raw materials. In doing so, the government office is taking an important step towards sustainable operations and reducing its ecological footprint. Circular sanitation concept for 6,000 employees #ms-container-ca1d950.has-background:before { background-color: transparent; } @media screen and (max-width: 39.9375em) { #ms-container-ca1d950 { padding-top: 1rem; padding-bottom: 1rem; } } @media screen and (min-width: 40em) and (max-width: 63.9375em) { #ms-container-ca1d950 { padding-top: 2rem; padding-bottom: 2rem; } } @media screen and (min-width: 64em) { #ms-container-ca1d950 { padding-top: 2rem; padding-bottom: 2rem; } } Location:Rijnstraat The Hague Client:Ministry Market:Decentralised wastewater treatment Year of completion:2016 #ms-container-8324491.has-background:before { background-color:transparent; } #ms-container-f69b540.has-background:before { background-color: #E8F3FF; } @media screen and (max-width: 39.9375em) { #ms-container-f69b540 { margin-bottom: 1rem; padding-top: 1.5rem; padding-bottom: 1.5rem; } } @media screen and (min-width: 40em) and (max-width: 63.9375em) { #ms-container-f69b540 { margin-bottom: 2rem; padding-top: 3rem; padding-bottom: 3rem; } } @media screen and (min-width: 64em) { #ms-container-f69b540 { margin-bottom: 2rem; padding-top: 3rem; padding-bottom: 3rem; } } Within the building, different wastewater streams are collected separately and processed efficiently. Desah supplied the system for treating the black and grey wastewater. The black water from the vacuum toilets, together with organic waste, is collected in a concentrated form and fermented in a special fermentation tank. This fermentation process produces biogas, which is used to heat the building. This significantly reduces dependence on fossil energy sources. The water from the urinals is separated from the black water and processed in a struvite reactor, where phosphate is recovered in the form of struvite, a high-quality fertiliser that is directly applicable in agriculture. In doing so, the concept contributes to the circular nutrient chain. The use of waterless urinals and vacuum toilets saves a considerable amount of drinking water. This not only leads to less burden on the water chain, but also to lower operational costs. Lower drinking water costs Less treatment levy Recovery of raw materials Lower operating costs #ms-container-54879e7.has-background:before { background-color: #133596; } @media screen and (max-width: 39.9375em) { #ms-container-54879e7 { padding-top: 1.5rem; padding-bottom: 1.5rem; padding-left: 1rem; padding-right: 1rem; } } @media screen and (min-width: 40em) and (max-width: 63.9375em) { #ms-container-54879e7 { padding-top: 3rem; padding-bottom: 3rem; padding-left: 2rem; padding-right: 2rem; } } @media screen and (min-width: 64em) { #ms-container-54879e7 { padding-top: 3rem; padding-bottom: 3rem; padding-left: 2rem; padding-right: 2rem; } } #ms-container-df18625.has-background:before { background-color: transparent; } @media screen and (max-width: 39.9375em) { #ms-container-df18625 { padding-top: 1.5rem; padding-bottom: 1.5rem; } } @media screen and (min-width: 40em) and (max-width: 63.9375em) { #ms-container-df18625 { padding-top: 3rem; padding-bottom: 3rem; } } @media screen and (min-width: 64em) { #ms-container-df18625 { padding-top: 3rem; padding-bottom: 3rem; } } Type source-separated Capacity6000 PE Delivery design, assembly and commissioning Dimensions2.4 m x 1.2 m x 1.5 m Noise level< 30 dB #ms-container-3391540.has-background:before { background-color: transparent; } @media screen and (max-width: 39.9375em) { #ms-container-3391540 { padding-top: 1.5rem; padding-bottom: 1.5rem; } } @media screen and (min-width: 40em) and (max-width: 63.9375em) { #ms-container-3391540 { padding-top: 3rem; padding-bottom: 3rem; } } @media screen and (min-width: 64em) { #ms-container-3391540 { padding-top: 3rem; padding-bottom: 3rem; } } From placement to final result - a compact project with great impact. #ms-container-def4e3e.has-background:before { background-color: transparent; } @media screen and (max-width: 39.9375em) { #ms-container-def4e3e { padding-top: 1.5rem; padding-bottom: 2.5rem; } } @media screen and (min-width: 40em) and (max-width: 63.9375em) { #ms-container-def4e3e { padding-top: 3rem; padding-bottom: 5rem; } } @media screen and (min-width: 64em) { #ms-container-def4e3e { padding-top: 3rem; padding-bottom: 5rem; } } Do you have a property in the countryside or a location without a sewer connection?

The Oceanhamnen residential area uses an innovative, circular Desah system. Here, greywater and blackwater are collected and processed separately. In addition, the houses are equipped with food grinders in the kitchen, which dispose of food waste directly and process it locally. The sanitation system is housed in the RecoLab, a development facility for research and with an exhibition area for visitors. This facility is a globally unique system for source-separated wastewater treatment that recovers important raw materials. As such, it fits perfectly with Helsingborg's ambition to become a fully circular city. The Helsingborg project received international recognition. In 2015, Desah won the Swedish Innovation Award in the “Blackwater and Food Waste Challenge”, in the Treatment Plant category. And in 2022, the project was awarded another prestigious prize: the Global Water Award in the Wastewater Project of the Year category.

This included the installation of a digester for black water, which produces biogas. Kitchen waste is also processed locally: for this, Desah supplied the digester and hygiene units that process food waste. Grey water from showers, sinks and washing machines is biologically purified and then polished using nanofiltration, so that it can be safely reused or discharged. An advanced control and automation system was integrated for stable and efficient operation. Desah also provided on-site operator training and supervised the start-up and commissioning of the entire system.
