Franktown is a small unincorporated ranching community, and we couldn't verify any public water or sewer provider there. Whether you're on a sewer system or a private onsite wastewater system, the pipe leaving your house can still fail and be replaced. Call the number on this page to be connected with a local plumber in Franktown.

What we know about Franktown
Franktown sits at the junction of State Highways 83 and 86, about 7 miles east of Castle Rock and 9 miles south of Parker, and has kept a distinctly rural identity. The former Town of Frankstown was declared abandoned by the Colorado Department of State in 2007, so today it's unincorporated Douglas County. Our fact sheet names no water or sewer provider for Franktown. Rather than guess, we'll say it plainly: providers, if any, vary by address. Check your utility bill for a sewer charge, or ask Douglas County about your property.
If your home isn't on municipal sewer, it uses a private onsite wastewater system, and the line a plumber works on runs from the foundation to that system's tank. Work on the tank and field itself is a separate specialty under county rules. Knowing which setup you have before anyone digs saves time, because the route, depth and endpoint of the line are different in each case.
| Situation | Usual approach | Rural considerations |
|---|---|---|
| One cracked or separated joint | Section repair | Small dig near the defect |
| Roots at several joints | Replace the line | Long runs mean more pipe |
| Sag holding water | Dig and reset to proper slope | Frozen ground slows winter work |
| Line sound but backups continue | Look further along the system | A full tank can mimic a bad line |
Signs of a failing line
- Slow drains throughout the house
- Gurgling as fixtures empty
- The lowest drain backing up first
- Odor or soggy ground between the house and the tank or street
Permits and timing
Because Franktown is unincorporated, the Douglas County Building Division handles permits, including its Mechanical / Plumbing permit. It's at 100 Third Street in Castle Rock, 303-660-7497. The plumber will usually file the permit and book the inspection. On a rural lot, ask for camera footage of the full run before deciding between a repair and full replacement, and if the line is still working, schedule digging outside the coldest weeks. If you have a well as well as an onsite system, mention it when you call, so the plumber can keep the drain line work clear of the well and its water line. Long gravel drives and gates also affect how equipment reaches the house, so note anything the crew should know about access.
