Offstream Reservoir Pump Station

Project Overview

The Tampa Bay Water Offstream Reservoir Pump Station is a new facility that pumps 120 MGD of raw water from Tampa Bay Water's regional reservoir to the surface water treatment plant in Brandon, Florida. It consists of four vertical turbine pumps using 72-inch diameter suction cans that extend 35-feet into the ground. The project also includes a 28-foot-deep valve vault that houses an 84-inch motorized butterfly valve and a 54-inch buffered check valve. Additionally, there is a tie-in to an existing 84-inch raw water main, and all interconnecting pipe are 84-inch mortar-lined steel.

This project required extensive dewatering, excavation through existing limestone, and groundwater elevations monitoring 24 hours per day through a telemetry system.

The project had a major shutdown at the tie-in point. The tie-in was 25 feet deep and included three 72-inch butterfly valves. This tie-in and shutdown were on the primary source of water for the entire Tampa Bay region. This operation was accomplished by working 24-hour shifts and was completed one day ahead of schedule.
