Student halls in Hannover

Save water by re-using it

Save water, reduce operating costs and protect the environment – this is the promise made by Hansgrohe grey water recycling systems*. In Hannover, a student halls of residence has been cleverly redeveloped with this technology: recycled grey water from bathrooms is used in the toilets, saving precious drinking water.

The Pontos AquaCycle 4500* installed in this residence for 76 people uses a treatment process that does not involve the addition of chemicals to treat water from showers and wash basins, preparing it for a second use: for flushing toilets. If the amount supplied is insufficient, fresh water is mixed in so that the supply to toilets is not interrupted.

Hansgrohe’s patented procedure ensures consistently high water quality that complies with the hygiene requirements of the EU Bathing Water Directive.
