Water Infrastructure Project to Begin in Poway

Construction will start soon on the first of three projects to increase the reliability of drinking water for Poway water customers now and generations to come. Two water storage tanks will be built as part of a temporary bypass project.

During construction access to some amenities at Lake Poway will be impacted.

The ballfield at Lake Poway will be closed beginning Monday, September 20 for the construction of two tanks, each with the capacity to store 1.4 million gallons of treated water. The tanks are part of the temporary bypass project, which once completed will allow the city to move forward with replacing the clearwell (treated water storage) at the water treatment plant.

The parking lot adjacent to the volleyball court will be used for equipment staging and parking. It tentatively will be fenced off the week of Sept. 13. The Public Works parking lot off Lake Poway Road, which is open to the public for free parking on the weekends, will be closed beginning Sept. 20.

The clearwell replacement project is expected to be completed by Fall 2024. At that time the ballfield will be fully restored and both parking areas will reopen.

Largest Capital Improvement Program in Poway history

With the goal of increasing the reliability of drinking water for water customers now and generations to come, the City of Poway is undertaking the largest capital improvement program (CIP) in the city’s 40-year history.

The CIP will include replacing the clearwell (water storage reservoir) at the water treatment plant and a new San Diego County Water Authority treated water connection and redundant pipeline. In order to replace the clearwell, a temporary bypass project will include two 1.4 million-gallon tanks for storing treated water.

Water Authority treated water connection/redundant pipeline

The San Diego County Water Authority treated water connection and redundant pipeline project provides Poway with its first treated water connection to the SDCWA’s treated water aqueduct, as well as providing redundant pipelines. The project will help diversify Poway’s water supply portfolio and allow for operational flexibility and plant maintenance. It will also provide a redundant pipeline to the 36″ water transmission line on Lake Poway Road, which is currently the single transmission line that carries treated water to the distribution system.

The infrastructure improvement projects are moving ahead as part of a mutually beneficial agreement between Poway and the State Division of Drinking Water.

(Editor’s note: The City of Poway is one of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region.)
