This project was realised in cooperation with the planning office of WAFI GmbH in Cottbus and Pumpen-Bertold e.K. in Chemnitz. Installed is the STRATE sewage pumping station AWALIFT 4/2 in special stainless steel design. The station was equipped with chemically nickel-plated pumps ST100/269, each with 30 kW and 3000 rpm. The level is controlled by a redundant double measuring system HWAS-BN, which consists of two independent measuring systems with different functions and thus increases the operational safety of the sewage pumping station. The switchgear consists of a programmable logic controller - Siemens Simatic S7 with frequency converters and completes the pumping station from STRATE.
