Series Finished Water Pumping Facilities

by Floyd F. Eunpu, Fairfax County Water Authority, Engineering & Construction Div, Merrifield, VA, USA,
Roger J. Cronin, Fairfax County Water Authority, Engineering & Construction Div, Merrifield, VA, USA,



Document Type: Proceeding Paper

Part of: Hydraulics and Hydrology in the Small Computer Age

Abstract:

The paper discusses studies and design of series finished water pumping facilities for the Potomac River Water Treatment Facilities. Detailed hydraulic studies were conducted which concluded that it was feasible to design the station for series and parallel pump operations. This allowed the same pumping units to be used in the future when the station capacity is increased by 50 percent and discharge pressures are reduced by 57 percent. The as-designed facilities allowed the Fairfax County Water Authority, VA, to reduce initial construction costs, provide for future expansion, increase pump operation efficiency, increase flexibility in pumpage rate selection and simplify pump operation.
