The Town of Larkspur's Public Works operates the wastewater system within town limits and bills water and sewer together. When the line from your house backs up, a sewer camera inspection shows whether roots, cracks, a sag or a blockage is the cause. Call the number on this page to be connected with a local plumber in Larkspur.

What happens when you call
The number on this page puts you in touch with an independent local plumber who serves Larkspur. They will ask which drains are affected, whether anything has backed up, and where the cleanout is. On site, the plumber clears the line if it is full, runs a camera from the cleanout toward the main and watches the image live. Each defect is noted by distance and located from above so it can be marked on the ground.
Cost factors
- Cleanout access versus entry through a toilet or vent
- Clearing a backed-up line first
- Length of the run and number of bends
- Surface locating and saving the recording
- Off-hours timing for an urgent backup
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's Public Works Department runs the water and wastewater systems within town limits, overseen by a Water and Sewer Board, with the water system operated under contract by Semocor, Inc. Water and sewer are billed together. Town Hall is at (303) 681-2324 during business hours; the Town's after-hours contact for water emergencies is Semocor at (303) 681-2253. Our fact sheet does not say where the Town's responsibility for the sewer line ends, so if the camera finds a defect near the main, ask Town Hall before assuming who handles it.
Areas of ZIP 80118 outside town limits are not covered by the Town's systems, and some of those homes may not be on municipal sewer; for them, a camera checks the pipe to the tank, not the onsite system. Inside town, the Town Building Department, not Douglas County, handles building permits, with SAFEbuilt doing inspections (720-641-1956). Valley lots and creekside trees mean roots and shifting soil are both worth watching for on camera.
Before the visit
- Stop using water if drains are backing up
- Find the cleanout and clear access
- Move belongings away from the lowest drain
- Note which fixtures are affected and when
- Confirm whether you are inside town limits
