Major Reservoir Upgrade is Part of Poway Water Infrastructure Program

Construction on the City of Poway’s clearwell replacement is anticipated to begin this fall following the award of contract to Gateway Pacific Contractors, Inc. The contract was awarded at the Sept. 19 Poway City Council meeting.

The clearwell is Poway’s major storage reservoir for water treated at the water treatment plant, prior to being distributed to Poway water customers.

Construction on the City of Poway’s clearwell replacement is anticipated to begin this fall following the award of contract to Gateway Pacific Contractors, Inc. The contract was awarded at the Sept. 19 Poway City Council meeting.

The clearwell is Poway’s major storage reservoir for water treated at the water treatment plant, prior to being distributed to Poway water customers.

Poway Water Infrastructure Program

Replacing the aging clearwell, built in 1964, is the second phase of the Water Infrastructure Improvement Program. This program is the largest capital improvement program (CIP) in the city’s 43-year history. The first phase of the program built the infrastructure necessary to bypass the clearwell. The improvements to Poway’s water system will increase the reliability of drinking water for water customers now and for generations to come.

The two tanks that will be built as part of the clearwell replacement project, will provide Poway’s water system with redundancy and operational flexibility in that one tank can be taken offline for maintenance and repairs without interrupting service. Gatweway Pacific was the lowest responsible bidder for the project, with a bid amount of approximately $31.6 million.

The targeted construction start date is Fall 2023 and will include the restoration of the ballfield at Lake Poway once the new tanks are operational. The project is expected to be completed in Fall 2026.

Water Projects Overview

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 bypass system consisting of two 1.4 million-gallon tanks, pipelines, a pump station and other appurtenances will be constructed.

These infrastructure improvement projects have been in the planning stage for a long time and are moving ahead as part of a mutual agreement between Poway and the State Division of Drinking Water.

SDCWA 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 Water Authority’s treated water aqueduct, as well as providing redundant pipelines. This 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 Poway City Council considered approval of the engineering design agreements during the April 5, 2022 City Council meeting. The City is also working with the Water Authority to evaluate alternatives to reduce the cost of this project.

(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 San Diego County region.) 

Lake Poway Water Level Temporarily Reduced for Maintenance

Lake Poway’s water level is lower today, but it isn’t due to the current heatwave. The lake is being temporarily reduced to complete a planned maintenance project to replace a transducer.

Lake Poway serves as the City of Poway’s main water storage reservoir, with a capacity to hold more than one billion gallons of water. A transducer measures the lake’s water level and remotely sends data to the city.

Lake Poway Water Level Temporarily Reduced for Maintenance

Lake Poway’s water level is lower today, but it isn’t due to the current heatwave. The lake is being temporarily reduced to complete a planned maintenance project to replace a transducer.

Lake Poway serves as the City of Poway’s main water storage reservoir, with a capacity to hold more than one billion gallons of water. A transducer measures the lake’s water level and remotely sends data to the city.

The city typically takes advantage of lower summer lake levels every year as part of a process to maintain the water quality and for maintenance.  Water drawn down from Lake Poway is sent to the Lester J. Berglund Water Treatment Plant for treatment. Replacement water is added back in from supplies the city purchases from the San Diego County Water Authority.

Drinking water is not being discarded. Instead, the City of Poway is moving drinking water into the delivery system for treatment, and holding back on replenishing the lake until the maintenance project is complete.

The work creates a bonus for San Diego County’s avid fishing fans.

“It’s not unusual for the water level to be down in the lake this time of year,” said Allie Margie, Recreation Supervisor at Lake Poway. “Our night fishing and catfish restocking schedule aren’t affected – and with less water and more fish in the lake, your chances of making a catch might be better than ever.”

Poway operates a modern water treatment and distribution system. Lake Poway serves as a storage reservoir for imported water from both the Colorado River and Northern California.

Water flows through the Berglund Water Treatment Plant, where approximately three billion gallons of drinking water are treated every year for the citizens of Poway. Once treated, the drinking water enters a system of pipes, pump stations, reservoirs for delivery to customer’s homes and businesses.

Did you know?

  • The City of Poway maintains about 294 miles of water pipe.
  • There are approximately 2,345 fire hydrants throughout the city.
  • There are over 5,044 valves in the water system.
  • Employees working in the water system are required to be certified by the State of California to work in a water system.

 

Water Bill Credits Approved by Poway Council

Poway City Council members voted 4-1 Tuesday night to give most city water customers small credits on an upcoming bill due to last year’s six-day boil water advisory.

The average customer will see a one-time credit of about $28.72 in March or April, depending on which bimonthly billing cycle the customer is on. This includes a $5.29 credit on the fixed rate and $23.43 for commodity equal to 1/8th of the bimonthly bill. Seventy-seven percent of all water customers will have a commodity credit of between $10 and $50, depending on how much water they typically use.

Poway Water Customers May be Getting Credits

Poway water customers may be in line for small credits on an upcoming bill because the recent six-day boil-water advisory late last year.

Pending the council’s likely approval, the typical residential customer will see a one-time credit of about $28.72 in either March or April, depending on which bimonthly billing cycle the customer is on.

With Water Crisis Over, Poway Businesses Regroup

Restaurants in Poway reopened Saturday morning after six days of darkness, with owners and employees happy to be back at work, but upset about the costly interruption to their businesses and lives.
A week ago, restaurants, bars and other businesses that handled food — about 190 in all — were ordered to close by the county’s health department after the state issued a boil-water advisory for the entire city.
