The existing dry-weather sewage pumps were installed in 1999, and control,operation modifications were made in 2002. When the:dry-weather pumps are out-of=service, the larger pumps are operated at low speeds to'conveydry weather flows: While running at-reduced capacity, the large pumps cannot handle fibrous materials and require service to de-rag the pumps,every 24-48 hours. Operation of these largepumps at such a reduced capacity isenergyinefficient. The project scope included-replacing the two smaller dry-weather pumps with modem sewage pumps to improve the overall operational efficiency and reliability of the station.
