7. Why is water from reservoir tanks and fire hydrants drained? Can it be used?: Flushing a fire hydrant or reservoir tank is necessary to maintain, protect and meet water quality standards. Only the required amount of water is released. And while it seems like a waste of water, reusing the water is not economical. In order to save $800 worth of water while lowering a reservoir for maintenance, it would cost $3,000 to collect and transport it to Lake Poway. City staff continues to monitor and evaluate new methods or tools that may be developed to make it economically feasible to capture and reuse this water.

8. Who can I call if I observe water waste?: Water issues can be reported to the City by calling (858) 668-1215.
