Welcome to all things water at the City of Westminster. We are committed to providing our community with high-quality and reliable water services now and into the future. The Public Works and Utility (PWU) department is responsible for treating up to 59 million gallons of water each day through our two water treatment facilities and distributed through about 554 miles of pipes to our homes and places of business. Additionally, our wastewater system treats over 7 million gallons of wastewater per day from 400 miles of pipe each year at our Big Dry Creek Wastewater Treatment Facility. Lastly, with our commitment to sustainability in mind, we have 120 reclaimed water sites, which make up over 1,100 irrigated acres. These sites can be found throughout the city in parks, golf courses, schools, sports fields, commercial properties and HOA common areas.

Below are links to learn about our drinking water, wastewater, and stormwater systems and infrastructure in addition to learning about how the City is looking ahead to protecting water for future generations. You can also find helpful information about paying your bill, pipe leaks, water main breaks, and drought planning.

Learn about our water utility:

The City of Westminster has provided its residents water since 1955. Prior to 1955, the City provided water for its residents solely from groundwater wells. As Westminster grew, so did our need for new forms of resource collection and allocation. In the 1960s, the City began negotiations about managing Standley Lake and securing its own water management. Today, we are proud to manage Standley Lake for our residents and our neighbors in Northglenn, Thornton, and the Farmers Reservoir and Irrigation Company. Click here to learn more about the history of water in Westminster.


We’re fortunate to be close to our drinking water source. The water we provide our residents comes from the snow pack in the Rocky Mountains along Loveland and Berthoud Pass on the east side of the Continental Divide. The melting snow in the spring and summer is surface water which flows into Clear Creek and then travels through three canal systems before it makes its way to Standley Lake. The lake stores up to 13 billion gallons of water, about half of which is owned by the City of Westminster. 


We have over 33,000 customers! In addition to City of Westminster residents and businesses, we also provide water to the City of Federal Heights, Shaw Heights, and parts of unincorporated Adams and Jefferson County.

Check out the new customer portal - Westy Water

Westminster’s new customer portal offers residents the ability to monitor water consumption and receive emergency leak alerts via email. Current Paymentus account holders will only need to update their password to access Westy Water. Learn more here.

We understand that financial hardship happens, and we are here to support you. Income-qualified residents can apply for assistance online at www.westminsterco.gov/WaterBillAssistance. Please call 303-658-2392 if you have any questions.

Step 1: Determine If You Have A Leak

If you received a Possible Leak Alert postcard or letter, it means that your water meter registered continuous water use for 24 hours straight. Using water for 24 hours straight usually indicates that there is a leak, but continuous water use can be caused by other things like a swamp cooler or humidifier. 
Check the water bill to see if your consumption was higher than last month, or the same month of last year.

Step 2: Find And Fix The Leak

Leaks can be anywhere, but in our experience, the most common source of unknown leaks are toilets and sprinkler systems because they can leak without you realizing it. Check out the tips below to find and fix common leaks. 

Step 3: Phone An Expert 

The City of Westminster and Resource Central have partnered to provide FREE troubleshooting support if you can't find that pesky leak.
These appointments are short phone calls with a water expert who will go over your water use history and help you identify the source of the leak. At the end of these calls, you will be provided with tips to fix the leak yourself, or if the leak will require a professional.
Schedule an appointment online or call 303-999-3820.
*This service is only for our residential customers because non-residential water uses tend to be much more complex. Non-residential customers may need a professional plumber or landscape maintenance firm to investigate leaks further.

Step 4: Apply For A Leak Credit

We get it. Leaks happen and the cost can add up. The city has a process in place to credit some of the costs incurred on your monthly water bill as a result of a leak. 

Some things to keep in mind:

  • Customers qualify for one leak credit billing adjustment per calendar year
  • Credit will reduce all excess charges to the Tier 1 rate
  • Credit application must be submitted within two months after leak occurred
  • Water usage must be 150% above your three-year average for the same time period
  • Leak must be fixed or the accidental use stopped
  • Credit will apply to a maximum of two bills
  • No credits to flat-rate customers (multi-family, irrigation customers)

Westminster’s goal during any snowstorm is to keep primary and secondary streets open and safe for the public. In addition, priorities are given to streets adjacent to hospitals, police, fire/rescue squad stations, schools, RTD bus routes and dangerous intersections, hills or curves on residential streets.

Residential streets only receive service if snow accumulations are greater than 8 inches and after the above priorities are addressed.

Want to know where your residential street or business fits in the city's snow removal routes? A new city map shows which streets are maintained by the city, Colorado Department of Transportation, Adams or Jefferson County or another municipal entity.

Current Projects:

A portion of your utility bill supports funding projects that maintain and improve our water systems for both drinking water and wastewater. These projects include replacing water meters with digital meters, installing new water and sewer mains under the ground, and repairs and updates to our treatment facilities. Below is a list of our active projects. To learn more, click on each project and sign up for their project updates.


Westminster Boulevard Drinking Water Project

Status: 30% Design 

The City has made significant progress on the future of water in Westminster. Over the past year, under City Council’s guidance, the City reevaluated options for Westminster’s new water treatment facility to better balance the need for clean, safe, and affordable water. Learn more about the right-sized water treatment facility here


Big Dry Creek Streambank Restoration Project:

Status: Construction

The City of Westminster is teaming up with the Mile High Flood District to improve Big Dry Creek’s water quality and flood management capabilities, and make it more resilient to intense storm runoff events. Together, we are repairing and stabilizing streambanks from 112th Avenue to Wadsworth Boulevard. This project will address Big Dry Creek’s stream instability, flood management, and maintenance needs. Years of urban runoff has led to steep, unsafe streambanks. This degradation is also approaching sewer pipes and trails, which need to be protected from further damage. Mitigating these risks will allow our community to continue safely enjoying activities along the Big Dry Creek for years to come.


Northridge Water Storage Tanks:

Status: Construction

We will be replacing two aging water storage tanks near City Hall with replacement 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.
