 Water Conservation

City Maintains High Water Storage Levels, Asks for Voluntary Conservation - Due to the benefits of senior water rights and reduced water demand, Westminster's water storage in Standley Lake remains full or close to full. While conditions may still change, continued conservation efforts by citizens, along with Westminster's prudent water planning, allow Westminster to request only voluntary water conservation measures be implemented.

Westminster holds some of the most senior water rights on Clear Creek. Because of this, any shortage on Clear Creek must reach a significant level before Westminster's supply is seriously affected. As we saw in 2002 those levels do occur, but only under extreme circumstances. Westminster's storage in Standley Lake lets us carry water over from average and wet years to address deficits in these extreme circumstances.

Conservation Rebate Program
The City of Westminster offers the following rebates to customers who purchase specific water-saving appliances. Rebates are limited and available on a first-come, first-served basis while funds are available.

Toilet rebates - Rebates for standard 1.6-gallon toilets are $25 per toilet. Rebates for high-efficiency toilets that use less than 1.3 gallons per flush, are $100. Federal regulations require that all new toilets flush no more than 1.6 gallons per flush. New technology used in high-efficiency toilets reduces flush volume by at least 20 percent. Other features include:

  • Dual-flush toilets use 1.6 gallon flushes for solids and 0.8 gallon flushes for liquids.
  • Pressure-assisted toilets have a pressure unit within the tank to provide a better flush with less water.
  • Improvements to standard gravity flush toilets reduce the amount of water required.

Qualifying high-efficiency toilets meet the requirements for the U.S. Environmental Protection Agency's "Water Sense" program.

Qualifying low-water use units must be purchased after Nov. 1, 2009. Answers to common questions are included on the rebate application. Additional questions should be referred to 303-658-2188.

Rebates for New Construction - Rebates for high efficiency toilets and urinals are also available for new construction projects which require a new water service.  For details call 303-658-2386.


Landscape Irrigation Tips - Landscape does not need the same amount of irrigation each month. As we look back at how much irrigation was needed in the past, we can project the future needs. Sprinkler system programs should be modified several times during an irrigation season to reflect watering needs. The easiest way is to set one watering schedule for spring, one for summer, and a final schedule for fall.

Here are the numbers - If your lawn needs 1" of water per week from mid June, July and through August, mid summer (the amount recommended by the Sod Growers Association for an attractive lawn planted in good soil) then spring and fall watering amounts can be cut in half to only ½" of water per week. Using this method you can have one program for your system from the beginning of your irrigation season through mid June. Create a second program for the mid June through August time period and finally, revert to your water saving spring program for September through mid October when most irrigation needs drop to near zero.

Remember, your landscape has specific needs. Watering times may need to be adjusted for your conditions. Start on the low end and adjust up, if needed. Use a straight-sided container like a tuna can to measure the amount of water your system is applying.

What is Reclaimed Water? - When water goes down the drains in your home or business, the City "recycles" and treats it for irrigation purposes. Use of this "recycled" water does not deplete the City's water supply. That's why parks, businesses, golf courses and other facilities that irrigate with reclaimed water are not bound by watering restrictions.
