Conservation in Westminster 

Water in Colorado is a precious and limited resource. Westminster has actively promoted water conservation and efficiency since the 1980s, and is committed to helping all customers make smart choices about their water use. Details about City-sponsored conservation programs and information are listed below.

Learn more about water conservation in your neighborhood and the statewide benefits it provides in this 11-minute documentary by the Colorado Water Conservation Board and the One World One Water Center at Metropolitan State University.

While conservation is an effort we can take year-round, in the spring and summer we turn our attention to the possibilities of drought in Westminster. Drought is a natural, reoccurring reality in our state. Drought happens when there is not enough water in our streams due to low precipitation. The City of Westminster has a plan for drought, but we need your help.

Learn the recommended length of time for running your irrigation system during the summer with this schedule.

Understand how to maintain your irrigation system.

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.

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.

The city provides up to two free, high-efficiency toilets and free indoor water-use inspections to income-qualified homeowners. Homeowners qualifying for the Bill Credit Program automatically qualify for this program. Click here to learn more and apply.

The city also partners with Mile High Youth Corps, Maiker Housing Partners, and Foothills Regional Housing to install high-efficiency fixtures in income-qualified, multi-family housing properties.

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

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.

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:
