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A complete redevelopment took place in the Noorderhoek residential area in Sneek: 282 outdated houses made way for 232 new, future-proof homes.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

What we delivered
VIn this project, Desah realised a complete system for decentralised wastewater treatment. 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.
Greywater 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, which ensures 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 plant continues to operate sustainably and efficiently.
Why this solution?
- Energy recovery: biogas production
- Saving water: 30% drinking water saving
- Resource recovery: production of struvite
- Reuse of sludge
- Removal of micropollutants

“What I like best is that the vacuum toilet consumes only one litre of water,” she says.”
