Highlands Ranch Water Supply

Today, the foundation of our community’s water supply is based on surface water and ground water, commonly referred to as a conjunctive use system. This means that water sources include both surface water from the South Platte River and groundwater from wells throughout Highlands Ranch. During the last four years, which have been drier than normal, nearly 75 percent of our water supply has been derived from the South Platte River. In the past, as much as 100 percent of our water supply has come from South Platte River sources. The long-term supply will use both sources.

Water Quality

Centennial Water & Sanitation District adheres to EPA and Colorado Department of Public Health & the Environment (CDPH&E) water quality regulations and cooperates with the Highlands Ranch Metro District to protect community water sources like McLellan Reservoir. Water quality is addressed both physically (water quality ponds) and through programs (public education of pollution prevention, erosion control and grading permits).

The Metro District’s municipal separate storm sewer system (MS4) is the open space drainage ways. The goal for improving stormwater quality in these drainage ways is focused on reducing the pollutants to the system and improving the drainage ways to provide wetlands and riparian habitat to filter the stormwater. This is accomplished with the Metro District’s channel stabilization program which is in cooperation with UDFCD and Douglas County. This program is funded by the stormwater fee and funds from UDFCD. The Metro District distributes brochures in water bills about how to reduce these pollutants. One of the goals of the program is to reduce litter and trash which is a focus of our public education programs.

If a spill of hazardous materials has occurred, please notify the Douglas County Sheriff’s Office at 303-660-7500 and the Metro District at 303-791-0430.
