The Dollars and Sense Behind Your Water Rate Increase.

 In Water Meter Upgrades, Water Quality, Water Rates, Water Service, Water Storage, Water Supply, Water Treatment

Effective April 1, 2022, a water rate increase is in effect to keep pace with the cost of delivering safe, clean drinking water to you. You will see the new rates on your May water bill. Just like all services, water rates are regularly adjusted to cover the rising costs of power, materials, and other commodities that are necessary for supplying water to all Thornton customers.

Investing in the system.

Although it amounts to about a dime a day increase for most customers, it represents a big investment in our community.

Maintaining our water system is a complex undertaking that is managed 24-hours a day, 7-days a week, 365-days a year by trained engineers, scientists, and certified staff. There’s so much that happens behind the scenes for us to be able to deliver the water you need with a simple turn of the tap.

Investing in each other.

Using water efficiently is a job for our entire community. We rely on you to help sustain our water resources long into the future, so we encourage all customers take advantage of rebates and to participate in water savings programs provided by the city.

Saving water all around the house is important, but because about 50% of the water used by residents is on outdoor landscaping, here are a few ways to plan ahead for water savings this summer:

  • Water-Wise Landscape Rebate
  • Irrigation Controller Rebate
  • Rain Sensor Rebate
  • Sprinkler System Consultation
  • Discounted Lawn Removal Service
  • Free H2Overhaul Kit
  • Discounted Garden In A Box

Together, there’s a lot we can do to preserve our water supply and help you save money on your bill during our hottest months.


Making cents of your water rates.

While no one likes seeing prices go up for something we depend on every day, a rate increase of about a dime a day for most customers helps ensure all of us enjoy clean, safe, reliable water.
