Sweetwater Authority distribution crews resumed its water system flushing program in northern National City on Monday, October 24, 2011. The “flushing” process is an efficient method to remove sediment deposits in the pipes and it improves water quality and system pressure. During the recent drought, flushing activities were scaled back to reduce water use. However, the program was resumed to improve water flows in the system and to clear sediment that can produce discolored water. While the system water is safe, the appearance and aesthetics are greatly improved with regular flushing maintenance. As part of the flushing maintenance process, customers may notice crews releasing water from fire hydrants and directing the water into nearby storm drains. Also, when crews are flushing an area, there may be a brief episode where you experience discolored water in your home or business. If the water appears discolored, it is recommended that you give it a few hours, then run your cold-water faucet for a few minutes to clear the water in the mains.
If you have any questions about the flushing program, or water quality in general, please call Sweetwater Authority’s Water Quality Laboratory at (619) 409-6805.
