The Parisian Inter-Community Waste Water Treatment Centre - S.I.A.A.P
The SIAAP operates a facility in Clichy to decant and lift water.
In 1856, the architect Belgrand selected Clichy for the Parisian waste waters to be rejected into the Seine River and built an outlet for a large drainage sump. There were many sorts of equipment in this area: decanting basins, a high water facility and a backflow facility built in 1936. Facades of these buildings are characteristic of architecture of the 30s.
