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 homes 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....

A full-scale demonstration project involving source-separated wastewater treatment is being launched in Canada. The future model for Canada is being tested in collaboration with the University of Alberta.

A complete redevelopment took place in the Noorderhoek residential area in Sneek: 282 outdated houses made way for 232 new, future-proof homes.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

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 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...
