Normal water use for Westminster households:

Winter

2,000 - 6,000 gallons is considered normal use during wintertime

  • The Westminster single family average water use is 4,000 gallons per month. 
  • This amount fluctuates based upon number of people in household and age of appliances. 

Summer

10,000 - 30,000 gallons is considered normal use during the summer

  • The Westminster single family average water use is 16,000 gallons per months in peak summer months
  • This amount fluctuates based upon outdoor water use.

* Monthly water use on your water bill is reported in kgal (thousand gallons)

Daily

Daily water use is measured in gallons (gal)

50-250 gallons per day is considered normal indoor water use.

  • Typical usage comes from drinking water, toilet flushing, cooking, showers, laundry, and dishwashing.
  • This number fluctuates based upon the number of people in a household and the age of appliances.

500-2,000+ gallons per day is considered normal outdoor water use.

  • Irrigation of landscaping fluctuates based upon size of yard and type of landscaping.

Hourly

  • 0 - 50 gallons per hour is considered normal indoor water use. 
  • 100 - 300+ gallons per hour is considered normal outdoor water use.

Irrigation timing:  With this schedule, learn the recommended length of time for running your irrigation system during the summer 

  • Cycle & Soak: Divide watering times into three short cycles to reduce runoff and grow a strong, healthy lawn.
  • Water Twice A Week: It’s enough to keep your lawn green most of the time, and for scorching summer weeks it’s okay to add a third day.

Irrigation Maintenance: Understand how to maintain your irrigation system.

Rain Barrels: Use rain barrels to collect precipitation and reuse it outdoors. Using rain barrels can help minimize the amount of treated drinking water needed to maintain lawns and gardens and reduce runoff pollution entering our local waterways.

HOA Rules: If you live in an HOA, your association cannot require you to have a turf grass lawn at your home – that’s been a state law since 2013! You still may have to make sure your landscape looks nice, but it can be fully xeriscaped. Look for ideas on how to make over your yard with our Garden in a Box discounts.

Large landscape irrigation audits are available to HOAs and commercial properties through a City cost share program. Contact the City through the information below.

Water Conservation Resources

Conservation efforts by Westminster residents have kept water rates low. This peer-reviewed study documents how water rates would have been nearly double today’s rates (an extra $600 per year) without conservation efforts: Conservation Efforts Limit Rate Increases For Colorado Utility.

In this short video, learn about what water and sewer rates pay for and why they sometimes increase even when residents conserve.

New development in Westminster pays its fair share to connect into the $4 billion water and sewer infrastructure system. New development is subject to water-conserving requirements, which include:

Common Water Quality Questions:

 

Understanding PFAS and The City of Westminster’s PFAS Testing Program   

The health and safety of our community is the City’s top priority. We believe routine water testing is an important and necessary action to ensure the safety of our drinking water. According to the U.S. Environmental Protection Agency (EPA), PFAS (per- and polyfluoroalkyl substances) are a group of manufactured chemicals that have been used in industry and consumer products since the 1940s because of their useful properties. One common characteristic of concern of PFAS compounds is that many break down very slowly and can build up in people, animals, and the environment over time. PFAS can be found in a wide variety of products, such as carpeting, cookware, food packaging, and clothing because they are resistant to heat, water and oil. They are also found in foams used to fight certain kinds of fires.

In June 2022, the EPA released new interim health advisory levels for some PFAS compounds including PFOA and PFOS. The Colorado Department of Public Health and Environment (CDPHE) is supportive of these new health advisory levels. According to the EPA, “The updated advisory levels, which are based on new science and consider lifetime exposure, indicate that some negative health effects may occur with concentrations of PFOA or PFOS in water that are near zero and below EPA’s ability to detect at this time.”

The City initially tested for PFAS compounds in 2013 and again in 2020 with results indicating PFOS and PFOA were not present in the drinking water below the laboratory’s minimum reporting limit.  This means the results are below the level at which current testing technology is able to reliably verify results —not that it isn’t present in the water. Both of these rounds of testing were completed before EPA’s lower health advisory levels were developed. We are engaging our partners at CDPHE for guidance on further testing of Westminster’s drinking water. The City is committed to following the latest science and guidance from the state and federal government, and we will provide additional updates to the community as more information is available.

In July 2022, the City was made aware that Thornton had PFAS results above the new EPA health advisory levels and was required by CDPHE to notify consumers about the situation. It is worth noting that Thornton draws water from other sources in addition to Standley Lake, while Westminster’s only water source is Standley Lake.  

During our first round of UCMR5 sampling in 2024 for 29 PFAS compounds, all were non-detected at concentrations far below the MCLs.

CDPHE recommends that people who are concerned about reducing their exposure to any level of PFAS can:

  • Use water treated by an in-home water treatment filter that is certified to lower the levels of PFAS or by using bottled water that has been treated with reverse osmosis for drinking, cooking, and preparing baby formula. Use tap water for bathing, showering, brushing teeth, washing hands, watering yards, washing dishes, cleaning, and laundry.
  • Reduce exposure from other sources. Visit https://cdphe.colorado.gov/pfas-health to learn more.
  • If you have specific health concerns, consult your doctor. An information sheet, “Talking to Your Health Care Provider about PFAS,” is available at https://bit.ly/PFAS-doctor.

To learn more about PFAS, please visit CDPHE’s PFAS page and the Environmental Protection Agency’s PFAS page. 

If you have additional questions about Westminster’s water quality, please email our water quality team at water@westminsterco.gov. 

Per- and polyfluoroalkyl substances- or PFAS- are human-made chemicals that are used for both consumer and industrial products. PFOA and PFOS, which are classified as PFAS, have been the most extensively produced and studied of these chemicals. They have been used to make carpets, clothing, fabrics for furniture, paper packaging for food, and other materials (e.g., cookware) that are resistant to water, grease, or stains. They are also used for firefighting at airfields and in a number of industrial processes. Because these chemicals have been used in an array of consumer products, most people have been exposed to them.

Between 2000 and 2002, PFOS was voluntarily phased out of production in the U.S. by its primary manufacturer. In 2006, eight major companies voluntarily agreed to phase out their global production of PFOA and PFOA-related chemicals, although there are a limited number of ongoing uses. Scientists have found PFOA and PFOS in the blood of nearly all the people they tested, but these studies show that the levels of PFOA and PFOS in blood have been decreasing. While consumer products and food are a large source of exposure to these chemicals for most people, drinking water can be an additional source in the small percentage of communities where these chemicals have contaminated water supplies. Such contamination is typically localized and associated with a specific facility, for example, an industrial facility where these chemicals were produced or used to manufacture other products or an airfield at which they were used for firefighting

Learn about lead and how Westy Water works to keep our community safe

  • Lead is not present in our source water nor in the water leaving our treatment plants.
  • Staff is not aware of any lead infrastructure in the city’s water system, including any service lines to a home or business
  • Be aware that plumbing within your building or home may contain lead components, including lead solder on pipes or faucets. City staff ensure that the water delivered to your home is appropriately treated to reduce the corrosivity of the water, thereby reducing the possibility of contaminants leaching into your drinking water from these components.
  • When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your cold water for 30 seconds to 2 minutes before using water for drinking or cooking.
  • If you would like to learn more, please contact our Water Quality staff at 303-658-2461.

 

Westy Water is conducting a water service line inventory for homes in Westminster

Over the past few years, the EPA has released regulatory updates for water service providers known as the Lead and Copper Rule Revisions (LCRR). In response to the LCRR's new requirement for a water service line material inventory, we are building out and confirming our inventory of residential service line material in Westminster. A water service line is the pipe that brings water from the water main to your home.  

The EPA requires that the City have two forms of verification for service line material on the public and private side of the service line. The first point of verification was completed during our water meter improvement program in 2019. Each side on the meter was visually inspected inside of the meter pit, and no lead service lines were identified at that time. The city-owned side and homes built after 1960 have received their second point of verification and are now complete. 

To date, we have only identified copper water service lines in Westminster homes; however, there may be galvanized steel service lines in some older homes. Galvanized steel pipes are coated with zinc to prevent rust and deterioration. Some galvanized service lines in service before 1961 may need to be replaced as part of the LCRR regulation.
