what's happening now?

northridge water tank replacement - project update 

extended work hours

crews may need to work saturdays from 8 a.m. - 5 p.m. through the fall to stay on schedule because of rain from earlier this summer. on these days, you might notice construction traffic and equipment in the area.

what you can expect during construction 

  • construction noise and large truck traffic in project area.
  • large drilling rigs and concrete trucks will be on site.
  • hauling trucks and construction vehicles will primarily enter and exit the construction site off yates street through the grace community church and rocky mountain tv network access driveway.
  • access to homes and businesses will be maintained during construction.
  • traffic control measures and flaggers will be in place to guide motorists around the work zone. no road closures are anticipated.
  • working hours are 7 a.m. to 5 p.m.; monday through friday (weekend work may be needed under special circumstances). 

dirt and noise control measures 

  • increased noise and construction activity is expected. this is a normal part of the construction process and should not cause any distress. 
  • the work site will be monitored, properly cleaned, and maintained through project completion. 

this work is a key part of our capital improvement program to ensure safe, reliable, and high-quality drinking water for the city of westminster. 

project background 

the city is 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. 

location of tanks:  

images below are of the current aging infrastructure for one of the two tanks that were recently removed. 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. 


as part of the northridge water tanks replacement project, crews will begin hauling materials and drilling piers starting mid to late january 2023, including concrete placement. this phase of the project is anticipated to be complete by end of march 2023.  

we are committed to being a good neighbor and protecting the surrounding neighborhood’s health and well-being. we apologize for the noise and dust as we prepare the foundation for the new water tanks installation. 




the design phase of the project began in fall 2021 with site survey, geotechnical investigation, and other field data collection work. 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 are currently expected to be removed in summer 2022 and construction of the replacement tanks will begin winter 2022/spring 2023.

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.
