Full Description

The town of Exeter, NewHampshire's Kingston Road booster pumping station was hard-pressed to meet its existing needs,much less the demands of a proposed new 142-unit retirement community. The town found theproposed development to be the final straw in pushing peak demands beyond the capacity of the265-gallon-per-minute (gpm) station, but in the end was provided a modernized station ofsufficient capacity, free of charge, pumping more flow with less electrical consumption.In accordance with its policy, the town required the developer to pay for all review, designengineering, and physical improvements to the station. At the town's request, CDM modeled thewater distribution system to evaluate the impacts to the suction side of the booster pumpingstation. While the analysis revealed that increasing the pump station capacity from 265 to 350gpm would have a negligible impact (less than 1 psi) on system pressures on the suction side ofthe pump station, the facility lacked the firm capacity needed to pump this flow with one pumpout of service. A review of the affected wastewater collection and pumping systems was alsoperformed, although the sewerage system is beyond the scope of this paper. Includes figures.
