This pump station houses one 2 hp jockey pump, two 20 hp domestic booster pumps, and two 100 hp fire pumps to boost water from the Brattleboro Water System to the Commonwealth Dairy facility for fire protection and process operations. The pumps are controlled using variable frequency drives to prevent sudden starts or stops. This station has an exterior standby generator with automatic transfer switch and has the capabilities to feed chlorine as needed. The project also included the addition of SCADA equipment at this station to provide data from the pump station to be sent to a central location in Brattleboro.
