Methods of Monitoring of Sewerage Pumping Stations (on the example of SPS № 10 of the St. Petersburg’s water disposal system)

Summary

Methods of the monitoring of sewerage pumping stations tested at the SPS № 10 of St. Petersburg are presented. These methods allow to determine (taking into account the changes in the receiving tank – pumps – network system during the operation) technological characteristics of reliability of the pumping station operation necessary for selection of pumps and substantiation of power saving decision at reconstruction.
