A complete redevelopment took place in the estate of Noorderhoek I in Sneek, a town in the Dutch province of Friesland. Over a 10-year period, 282 outdated houses were demolished to make way for 200 new houses.
This “Waterschoon” project proved to be an excellent opportunity to apply innovative and sustainable technologies to significantly reduce energy consumption and environmental impact. In this project we worked with a total energy concept. There is a heating and cooling installation that includes electric heat pumps and underground heat and cold storage. A high-efficiency peak boiler supplies part of the peak heat demand using locally produced biogas. This gas is formed after digestion of organic material from black water (toilet water), grey water (other water) and household organic waste (fruit and vegetable waste) from the neighbourhood itself. Thermal energy is also recovered from grey water.
The OLAND process (Oxygen Limited Autotrophic Nitrification-Denitrification) is used as a specific nitrogen removal technique.
