What's Happening Now?

Construction on the water tanks is now complete. Final site work will be completed Spring 2024.  

Check out this insider’s view of all it takes to build the tanks and make sure the city has clean, reliable water.  

Project background 

The City replaced 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.   

Location of tanks:  

Images below are of the old aging infrastructure for one of the two tanks that were recently removed and rebuilt. Both tanks were maintained to exceed their useful life. These two water storage tanks were built in 1968 and were removed due to structural safety concerns and will soon be replaced in the same location as the old ones.  



The design phase of the project began in fall 2021 with site survey, geotechnical investigation, and other field data collection work. The aging water storage tanks were removed in summer 2022 and construction of the replacement tanks began winter 2022/spring 2023. The tanks were completed winter 2023/spring 2024.

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.
