Optimal Capacity of Municipal Water Supply Pumps
Publication: Journal of the Water Resources Planning and Management Division
Volume 105, Issue 2
Abstract
Capital costs of pumping equipment include economies of scale; however, such costs are now dominated by diseconomies of scale related to operating costs. The diseconomies are produced by the demand charge component of electrical power costs. A conclusion is that special emphasis should be placed upon analyzing the potential savings due to matching pump capacity as closely as practicable with peak period demands in order to increase pump use factors, thereby lowering unit pumping costs. Power cost rate schedules in current use for municipal pumping in three states are presented in dimensionless form. A sample analysis of the potential savings due to short term planning horizons for pump capacities is presented.
