Steinhardt GmbH Wassertechnik products

Even when CSO’s and SSO’s are equipped with scum boards, considerable quantities of floatables and suspended solids still reach the waters. Sanitary articles, toilette paper and synthetics are left caught in the river bank after heavy rain. The waters are biologically and hydraulically “stressed”.

There are thousands of old overflows in sewer networks. When it rains, this is how considerable quantities of pollution, like sanitary articles, paper and synthetics, reach our waters. Old overflows are often at the performance limit of today’s design, which is why reconstruction through extending the overflow crest is often necessary when installing standard screens. If the narrow space cannot be corrected or the flow rate is not sufficient, then expensive new build CSO’s and SSO’s are necessary.
