Many factors influence decisions about water distribution
storage facilities, including cost-effectiveness,
terrain, and aesthetics. Water age analysis using sophisticated
hydraulic models has identified a consideration
that is often overlooked, the storage site.
Locating ground-level storage or standpipes on high
ground outside the demand area can have a detrimental
effect on water quality. In this research, a detailed
hydraulic model and extended period simulation were
used to analyze four cases with varying parameters,
including water level fluctuation and storage facility
type and location. A comparison of a standpipe outside
the demand area and an elevated tank within the
demand area found that the latter reduced water age
from 17 to 6 days.
A least-cost solution using ground storage or
standpipes may have been sufficient in the past, but
utility managers today should also weigh such factors
as location when planning new storage facilities.
Inadequate turnover because of a poor storage location
may add up to significant additional costs
in the future. Includes 6 references, figures.
