« Water is the most beautiful thing in the world. »

Thales of Miletus, Greek philosopher and mathematician

Space provided for water (SPW) corresponds to the space required by a water course or a water body for floods (security), for ecological issues (natural habitat) and human activities (art. 36a WPA, Water Protection Act). The Swiss Law charges the Cantons to release the SPW before December 2018. Until the approval of the defined SPW, a temporary solution has to be adopted. In general this provisory SPW is wider.


We advise Cantons and communities wishing to release the space provided for water for their waters.
