Inside Larkspur's town limits, the Town's Public Works Department operates the wastewater system, and the pipe from each house to the town main is private plumbing. When it fails, a plumber makes the repair, with permits from the Town rather than Douglas County. Call the number on this page to be connected with a local plumber in Larkspur.

When you call
You'll be connected with an independent local plumber who serves Larkspur and southern Douglas County. Be ready to say whether you're inside town limits, what's backing up and whether this has happened before. The plumber typically clears the line first, then uses a camera to look for roots, cracks or sags and to measure the depth and distance of any defect. That inspection decides the repair method and tells you whether the problem is in your pipe or the Town's main. If it's in the main, the Town takes over; if it's in your line, you'll get options ranging from a single spot repair to a full replacement, with an idea of how much digging each one involves.
What moves the price
- How deep the pipe is and how long the damaged stretch runs
- Rocky soil or large trees along the route
- Driveways, decks or outbuildings over the route
- Repair method: one joint, a lined section or a full replacement
- Town building permit and SAFEbuilt inspection
Larkspur conditions
Larkspur is a small town in the East Plum Creek valley of southern Douglas County along I-25, about 11 miles south of Castle Rock, best known as home of the summer Colorado Renaissance Festival. The Town bills water and sewer together, and its Public Works Department operates the wastewater system within town limits under a Water and Sewer Board. Drinking water comes from Denver Basin aquifer wells and is run under contract by Semocor. Areas of the 80118 ZIP outside town limits weren't covered by the Town's pages, so if you live out of town, your bill shows your sewer situation.
Inside town limits, the Town, not Douglas County, handles building permits. The Town Building Department is at 8720 Spruce Mountain Road (303-681-2324), and SAFEbuilt schedules inspections at 720-641-1956. For a problem in the public system during business hours, call Town Hall; the Town routes after-hours water emergencies to Semocor at 303-681-2253.
Rural-feeling lots can mean longer laterals, sometimes under gravel drives where vehicle weight can crack or shift a shallow pipe.
