Water

Thornton is committed to providing dependable and sustainable water resources for our customers to enjoy … now and into the future. We are proud to provide quality water services, from protecting water sources to distributing water to homes and businesses. While Thornton collects wastewater, it does not own or operate a wastewater treatment plant.
