Centennial Water District(breadcrumbs are unavailable)

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).

Stormwater Quality

The Metro District’s MS4 permit (municipal separate storm sewer system) is the document that governs 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 Mile High Flood District (MHFD) and Douglas County. This program is funded by the stormwater fee and funds from MHFD. 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.
