Utilities expend significant time, effort, and money to treat
water to a high standard. But within the distribution system, that
quality water may deteriorate over time if storage tanks are
under utilized or have poor mixing characteristics.
In this research, computational fluid dynamics (CFD) modeling,
water temperature measurements, and chlorine residual measurements
were used to determine mixing characteristics within
storage tanks, identify tanks with poor mixing (and thus the greatest
potential for water quality deterioration), and help modify
designs to improve mixing characteristics. Field data demonstrated
how modifications improved water mixing in an operating
storage tank.
Results of this study should boost confidence in the use of
CFD modeling and field temperature measurements as efficient
methods of assessing and improving water quality within distribution
system storage tanks. System managers can use these
tools to further their knowledge of how water ages in their own
storage systems and ultimately take steps to ensure that the
water they supply maintains its high quality from treatment
to tap. Includes 11 references, tables, figures.
