Amiblu - Hobas CSO Chamber

Early in 2017, the first CSO chamber on Swiss soil was installed in the Canton of Schwyz. A few months later, the second one was installed 200 km further to the south, in San Pietro, Canton of Ticino. The municipality was looking for a solution to manage overloads of its combined sewer during heavy rainfalls in an efficient and environmentally friendly way. Amiblu produced a CSO chamber from Hobas GRP pipes with 8 m length, which consists of a main pipe DN 800 and an overflow pipe DN 450. Additionally, a GRP valve chamber DN 1200 was supplied to throttle the outlet to the WWTP.
