Centennial Water & Sanitation District is the water and wastewater provider in Highlands Ranch. Centennial Water provides high quality water through the state-of-the-art Joseph B. Blake Water Treatment Plant located in Highlands Ranch. Wastewater is also treated at the Marcy Gulch Wastewater Treatment Plant to meet stringent water quality standards before it is discharged.
Centennial Water strives to ensure that our water resources are used wisely. Centennial Water’s strategy is to optimize the use of surface water. Over the past 25 years 90 percent of the water supplied has come from renewable river supplies.
Highlands Ranch residents are fortunate to have two water supply sources — the South Platte River to the west, and a massive aquifer underlying our region. Centennial can combine supplies from both sources to optimize the reliability, quality and cost-effectiveness of water. This joint use of renewable water with our vast underground aquifer allows Centennial Water to operate a true conjunctive use system. As a result, aquifers have been annually recharged for more than 10 years.
