IKEA Rothenburg

Rothenburg near Luzern, Switzerland | 2011

A rainwater harvesting system has been installed at IKEA's premises in Rothenburg (near Lucerne, Switzerland). The harvested rainwater is used not only to flush toilets, but can also be extracted from taps at various locations in order to irrigate outdoor areas. Collected from around one third of the roof area, the rainwater is piped to three WFF 300 vortex fine filters, cleansed and then stored underground ready for use.
