Pumping Stations

The North Street Pumping Station was constructed in 1945. This station is operated on a daily basis. It can operate alone or with the Miami Street Pumping Station. A complete renovation of pumps, motors, air system and electrical controls was completed in 1989. We have remote SCADA capabilities to control the pumps in this station. The operators stationed in the Power Plant have control of all pumps except the standby diesel, which still must be started by hand when the need arises.
