Abstract: Treated water storage can be used to attenuate peak day consumption rates in order that the design capacity of a water supply system, exclusive of the distribution system, can be reduced while providing equivalent service. A procedure is described for selecting the combination of storage and water supply system. There appears to be a potential reduction in the total project cost even with the added costs for storage. The analysis of the example system showed that reductions do occur in the transmission line diameter with the addition of treated water storage, but not in every case. Furthermore, a reduction in the transmission line diameter is not accompanied by a large cost reduction because of other costs such as power increase.
