Pressure Zone 3 Elevated Tank Sunset Ridge Tank Replacement Project

Project Overview

The City of Westminster is investing $9 million to construct a new elevated water tank on the site of old storage units. This water tank will hold 3 million gallons of drinking water and replaces the old Sunset Ridge  elevated tank that was first built in 1963 and aged out of operation.

Project Update

Painting of the new tank has been completed and site restoration should be completed in June. The new waterlines in 97th Avenue have been disinfected and will now be connected to the city’s existing system. Upcoming connections are planned for Monday June 1st, and Wednesday June 3rd. Customers will experience periods without water during the day while these new connections are made. Advance notification to each customer will occur prior to these planned outages.

The new tank is scheduled to be disinfected and brought into service the week of June 8th. Once the new tank is in service, modifications to the interior tank piping of the existing Hydropillar water tank (the west tank) will occur. Finally, one of the last items to be completed will be repaving of the impacted areas of 97th Avenue.

Timeline

Construction activities will be on-going over a two-year period with completion anticipated for the summer of 2020.

Project Impact

The work includes complex high-angle operations that require a long-term construction period and mobilization of specialized construction equipment (see rendering of new tank below). Due to the proximity of this project to you and other customers, the city is taking special precautions to minimize disruption and inconvenience to your daily routine, including:

  • Hiring a specialty contractor with high qualifications specifically for this type of work. 
  • Restricting work hours to Mondays through Fridays from 7 a.m. to 5 p.m. to limit the impact of construction equipment and work noise. Weekend and evening work will only be permitted if special circumstances arise.
  • Careful monitoring of contractor compliance to state and local permit requirements for noise and dust control. 
  • Sequencing the work to minimize the need for water service disruptions.
