Highlands Ranch Water provides sewer service, and for sewer emergencies it tells residents to have a plumber check the private sanitary service line first. A replacement covers that private pipe from the house to the district's main. Call the number on this page to be connected with a local plumber in Highlands Ranch.

What happens when you call
You'll be connected with an independent local plumber who works in Highlands Ranch. Expect questions about which fixtures back up, how long it has been going on and whether the line has been cleared before. The plumber will usually camera the line before quoting a replacement, because the price depends on where it has failed, how deep it sits and whether the old route can be reused.
Highlands Ranch is unincorporated, so building permits come from the Douglas County Building Division rather than a city. The Highlands Ranch Metro District notes that its own project approval is needed before the county will issue building permits, which can matter for work that disturbs metro district land. The plumber can confirm what applies to your lot.
What drives the price
- Length of the run from the foundation to the main
- Depth, and whether the pipe still has proper slope
- Landscaping, retaining walls, patios and driveways over the line
- Trenchless versus open trench
- County permit and inspection
Local conditions in Highlands Ranch
Highlands Ranch Water is the water and wastewater provider for all of Highlands Ranch and Solstice, and wastewater is treated locally at the Marcy Gulch Wastewater Treatment Plant. For a sewer emergency, the district advises calling a plumber first to check the private sanitary service line. Its 24-hour emergency line is 303-791-2185, and it will help shut off water at the curb stop during a private plumbing emergency, though problems on private property are generally the owner's responsibility.
The community was built from the 1980s onward, so original clay sewer pipe is unlikely. Failures here more often come from plastic pipe that has bellied where soil settled, a joint that was poorly bedded, or damage from fence posts, sprinkler work or tree roots finding a weak spot. Those problems are often localized, so it is worth confirming on camera that a full replacement is needed before committing to one.
Short checklist before the visit
- Limit water use until the line is checked
- Locate the cleanout, often near the foundation or in the front yard
- Note when backups happen and which drain goes first
- Have any HOA or metro district contact details handy
