Highlands Ranch Water maintains the service line from the main through the curb stop, and the homeowner maintains everything from the curb stop through the building, except the meter. A leak on your side is a job for a private plumber, and the district will help shut off water at the curb stop in an emergency. Call the number on this page to be connected with a local plumber in Highlands Ranch.

What happens when you call
Your call reaches an independent local plumber who works in Highlands Ranch; this site only connects you. Be ready to explain where the water is appearing, whether pressure is down throughout the house, and whether the problem started suddenly. The plumber may check the meter, listen for the leak, and trace the line from the curb stop to the house before recommending a section repair or a new line.
Cost factors
- Distance from the curb stop. Longer runs need more digging and pipe.
- Section repair or full replacement. One failed coupling is far less work than a new line.
- Landscaping and hardscape. Sod, sprinkler lines, patios and driveways all need restoring.
- Entry point. Many homes have finished basements, which affects how the pipe comes inside.
- Permits. Highlands Ranch is unincorporated, so building permits come from Douglas County.
Highlands Ranch conditions
Highlands Ranch Water, the Centennial Water and Sanitation District, serves every property in the Highlands Ranch and Solstice communities. That keeps the rules consistent across the whole community. The district owns and maintains all water meters and maintains the service line from the main through the curb stop, or to the property line if there's no curb stop. The homeowner maintains the line from the curb stop or property line through the building, excluding the meter.
The district states it has no lead service lines in its service area. Highlands Ranch was built as a master-planned community from the 1980s onward, so its lines are newer than in Denver's inner suburbs. Failures here tend to come from a joint letting go, ground settling, or damage from a fence, deck or landscaping project rather than old pipe wearing out.
During a private plumbing emergency, the district will help shut off water at the curb stop; its emergency line is 303-791-2185. Because the community is unincorporated, plumbing permits come from the Douglas County Building Division rather than a city office.
Short checklist before the plumber arrives
- Locate the main shutoff inside the house.
- Mark the wet area with a stake or flag.
- Turn off the irrigation system so it doesn't confuse the leak search.
- Clear storage away from where the line enters the basement.
- Have the district's emergency number handy in case the curb stop needs closing.
