Although the span of the City's Water Distribution system consists of 5 storage facilities, 7 MWD connections, 21 groundwater wells, 7 pump stations, 4 pressure regulating stations, and 2 pressure zones, this project will focus on performing the scope of work outlined in RFP NO : 23-026 for two stations: Crooke Station and for the Cambridge Station.
