Northridge Water Tanks Replacement Project

Just like your car or house, water infrastructure doesn’t last forever.

The city will be replacing two aging water storage tanks near City Hall with new water tanks that will provide reliable service decades into the future. Two of the three existing tanks were built in 1968 and need to be replaced due to structural safety concerns. The tank on the far east side of the property was built in 2016 and will remain on site.

Beginning in fall 2021, expect to see staff and contractors periodically visiting the site to drain the two tanks being replaced, survey the location of existing equipment, and complete geotechnical drilling to support design of the new tanks. Geotechnical drilling will provide information on soil conditions below the surface. Survey stakes will remain on site throughout the project, providing reference points during the design and construction of the new replacement tanks.

The aging water storage tanks will be removed in spring 2022 and construction of the new tanks will begin in summer 2022.

Delivering safe, reliable, and high-quality drinking water is one of the many ways the City of Westminster supports a thriving community. The city’s drinking water system includes over 500 miles of pipe, two water treatment facilities, as well as water storage facilities at strategic locations throughout the city.

The Northridge water storage facility, located near City Hall, consists of two 3-million-gallon drinking water storage tanks first built in 1968, a 3.5-million-gallon drinking water storage tank built in 2016, a reclaimed water standpipe, and pumps and valves connecting these tanks to the pipelines below ground.

These water storage tanks are critical to ensuring that Westminster has enough treated water available, even during times of peak demand, typically during the hottest days of the summer in July, and for fire emergencies. Combined with pumps, water storage tanks are also used to ensure consistent water pressure.
