Description
Many factors influence decisions about water distributionstorage facilities, including cost-effectiveness,terrain, and aesthetics. Water age analysis using sophisticatedhydraulic models has identified a considerationthat is often overlooked, the storage site.Locating ground-level storage or standpipes on highground outside the demand area can have a detrimentaleffect on water quality. In this research, a detailedhydraulic model and extended period simulation wereused to analyze four cases with varying parameters,including water level fluctuation and storage facilitytype and location. A comparison of a standpipe outsidethe demand area and an elevated tank within thedemand area found that the latter reduced water agefrom 17 to 6 days.A least-cost solution using ground storage orstandpipes may have been sufficient in the past, bututility managers today should also weigh such factorsas location when planning new storage facilities.Inadequate turnover because of a poor storage locationmay add up to significant additional costsin the future.
