The temporary treated water storage tanks on the Lake Poway ballfield are almost ready to go into service. As of Friday, July 15 the two tanks were filled, disinfected, and tested for bacteria. One of the final steps before the temporary pipeline can connect the tanks to the water treatment plant is a controlled flushing. This is a California Water Works regulation and must be completed.
The majority of the pipeline flushing is expected to take place later in the week of July 18, with additional pipeline flushing possible over the following weeks. Staff from Public Works water operations and stormwater divisions will be working with the contractor during this process and be in the field monitoring the flow of water. The flushed water will flow through Poway’s existing stormwater infrastructure.
The treated water storage tanks and pipeline are part of the temporary bypass project, the first of three projects in Poway’s $70 million capital improvement program (CIP) to increase the reliability of drinking water for water customers now and generations to come. The next step of the CIP is to replace the city’s aging clearwell (treated water storage reservoir), along with a third project to construct a treated water connection to the San Diego County Water Authority pipeline.
