This slide presentation outlines operation and modeling approaches for addressing water quality problems in the distribution system used by the Greater Cincinnati Water Works (GCWW) when it underwent a distribution system expansion. Water quality concerns included: infrastructure sized for future demand;
initial demand minimal; and,
sampling stations installed to monitor
water quality. Solution approaches included both operational and re-engineering. Operational approaches included change tank operation and
implement weekly flushing program. The re-engineering approach included division valve installation, and main extension and tie-in. Modeling results are provided on water age. Conclusions included: re-engineering activities can provide long-term
solutions to water quality problems in the
distribution system by minimizing retention time;
water quality sampling, operation approaches,
hydraulic modeling and water quality modeling
are useful tools in addressing retention time issues; and,
re-engineering activities can have positive
impacts in one area and negative impacts in
another. Consider the impact of re-engineering
activities on the entire distribution system. Includes table, figures.
