For a Highlands Ranch plumbing emergency, close the house main, or call Highlands Ranch Water's 24-hour line at 303-791-2185 for help at the curb stop; for a gas smell, leave and call 911 and your gas utility. Then call the number on this page to be connected with a local plumber in Highlands Ranch.

How the call works
The number connects you with an independent plumber who serves Highlands Ranch. Tell them what is leaking or backing up, whether the water is off and which neighborhood you are in. Ask about night and weekend pricing up front. Arrival depends on the hour and the plumber's workload, so no specific time is promised.
Cost factors
- The hour. Overnight, weekend and holiday calls usually carry a premium.
- Finished spaces. Opening and patching drywall in a finished basement adds time.
- What broke. A cracked supply hose is fast; a failed water heater or a damaged sewer line is not.
- Permits. Highlands Ranch is unincorporated, so permits come from the Douglas County Building Division, which lists water heaters on its plumbing and mechanical permit.
Water, sewer and gas in Highlands Ranch
Highlands Ranch Water (Centennial Water and Sanitation District) provides both water and wastewater for every property in Highlands Ranch and Solstice, and wastewater is treated locally at the Marcy Gulch plant. The district owns the meters and maintains the service line from the main through the curb stop. Everything from the curb stop through the building, except the meter, is the customer's to maintain. Plumbing problems on private property are generally the homeowner's responsibility, but the district will help shut off water at the curb stop during a private emergency. Its 24-hour emergency line is 303-791-2185.
For sewer trouble, the district advises calling a plumber first to check the private sanitary service line before assuming the main is blocked. The community was built from the 1980s onward, so most emergencies involve water heaters, supply hoses, frozen hose bibs and sprinkler lines rather than very old pipe. The district states it has no lead service lines.
Gas: the gas utility is listed on your bill. If you smell gas, leave the house and call 911 and that utility from outside.
Quick checklist before the plumber arrives
- Main valve closed and a basement faucet opened to drain pressure
- Water heater gas or breaker off if it is leaking
- Furniture and boxes moved off wet carpet
- Photos taken for insurance
- Pets secured and a clear path to the mechanical room
