Water/Wastewater Frederick Stormwater Pump Station #4 > Projects > Frederick Stormwater Pump Station #4 KEY CHALLENGES & PROJECT DETAILS Reconstructed Stormwater Pump Station #4 which activates when flooding occurs as 11% of the City of Frederick is in or near a 100-year floodplain. Installed two new 20-in., 30-ft. long vertical propeller pumps and motors with a capacity of 10,000 GPM each. Installed a temporary by-pass pumping system using two 8-in. pumps with a capacity of 5,000 GPM. Demolished the motor/diesel engine building and constructed a new control building and emergency generator. Cast-in-place concrete sump pump pit construction included saw-cutting the sump slab, excavation, and support of excavation. Constructed a Motor Control Center unit, control panel, generator, Automatic Transfer Switch unit, and HVAC. KEY CHALLENGES Constructed the 15-ft. deep cast-in-place concrete sump pump pit within a limited space. PROJECT DETAILS: Project Owner: City of Frederick Location: Frederick, MD Close
