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 a...

In Amsterdam's Buiksloterham district, circular living is being taken to the next level. In this progressive project, 550 houses are linked to the world's first floating wastewater treatment plant. This decentralised approach not only saves drinking water, but also generates energy and recovers valuable raw materials. On the quay in Sneek, the plant is built on...

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....

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. Future model for Canada tested Location:Edmonton,...

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. In the utility building Villa Flora, a pioneering concept was realised...

A complete redevelopment took place in the Noorderhoek residential area in Sneek: 282 outdated houses made way for 232 new, future-proof homes.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 offered 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, the...

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 is collected separately...

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 their technologies here and...

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...

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, wastewater is not seen as a residual flow, but as a valuable source for reuse. The homes will be equipped with a...

In the Lemmerweg Oost neighbourhood in Sneek, Desah realised a unique demonstration project in 2005: the world's first decentralised wastewater treatment system with source-separated sanitation. In 32 rented houses, wastewater has since been collected, purified and reused locally and completely disconnected from the conventional sewer system. This approach shows that decentralised wastewater treatment is not only sustainable, but also practical...
