What Aquafin does
What Aquafin does
Heat from waste water
Did you know that waste water contains a large amount of residual heat? With riothermie, buildings can be heated or cooled sustainably. This way, we reuse energy that would otherwise be lost.
Discharge or connect as a business
From dewatering water on a construction site to obligations regarding industrial waste water, businesses face specific regulations. Aquafin quickly clarifies what applies to your situation and guides you to the correct application process.
Purchase treated waste water
Did you know that treated waste water is a reliable water source? Effluent is continuously available, even during dry periods, and can be used for applications such as process water or irrigation. In this way, we give water a second life.
