The City of St. Joseph constructed a Lake Michigan intake and shorewell pumping station to provide additional capacity and reliability to the raw water supply, which serves over 38,000 residents in six communities. An intake study was performed to determine the location of the intake and the optimal distance from shore. The study included in situ water quality monitoring.
The intake includes approximately 4,700 feet of 48-inch concrete pipe. The raw water pumping station includes four pumps, and has a firm capacity of 20 MGD and a total capacity of 32 MGD. A chlorine feed system was included for control of invasive mussels. A sampling system was provided to enable raw water samples to be taken directly from the lake at the intake prior to chlorine addition. The project also included a dedicated standby power generator and a SCADA system interface.
