Centennial Water and Sanitation District is the water and wastewater utility in Highlands Ranch. Wastewater is also treated to meet stringent water quality standards before it is discharged.
Centennial strives to ensure that our water resources are used wisely.
As a result, aquifers have been annually recharged for the last 10 years. This annual practice is part of Centennial's routine preventative maintenance. The water main flushing program consists of opening fire hydrants and allowing water to run. This process keeps the water mains clean and verifies fire hydrant operation. Larger than normal water flow in the curb and gutter can be expected during this process.
