Role in City-zen
Waternet performs two City-zen projects:
- Supply of cooling with cold from drinking water. Cold will be extracted from the public drinking water infrastructure. This cold will be supplied to the Sanquin pharmaceutical plant via an ATES (aquifer thermal energy storage) system. This will result in a 1100 tonne / year CO2 reduction compared to conventional cooling machines.
- New sanitation’ waste water treatment and biorefinery: a local small-scale waste water treatment facility based on biological processes will convert organic waste into biogas and nutrients for plant fertilization (phosphate and nitrate). The system will be a net generator of energy.
