Henderson is a small unincorporated Adams County community, and parts of it have been annexed by Commerce City, Brighton and Thornton, so sewer service varies by address. The private pipe from the house to the public main or onsite system is still the repair a plumber makes. Call the number on this page to be connected with a local plumber in Henderson.

Signs to look for
- A toilet gurgles when the washing machine drains
- Wastewater comes up in the lowest drain in the house
- Drains everywhere are slow, not just one sink
- Odor outside along the pipe route
- Clogs that come back soon after clearing
Rural and semi-rural lots often have longer runs from the house, sometimes under a gravel drive or near outbuildings where trucks and equipment cross. Weight on a shallow pipe can crack it or push a joint out of line, and a pipe that has shifted collects debris until it blocks.
Why the provider question matters here
Henderson has a post office dating to 1894 and a handful of older buildings along Brighton Road north of 120th Avenue. Much of the surrounding land has since been annexed into Commerce City, Brighton and Thornton. The South Adams County Water and Sanitation District's Williams Monaco Wastewater Treatment Plant is on Monaco Street in Henderson, but that doesn't establish which Henderson homes are on its sewer. No sewer provider for Henderson homes was confirmed, and providers vary by address.
The practical step is to look at your utility bill. If it shows a sewer charge, that entity owns the main and can tell you whether a backup is on its side. If there's no sewer charge, the home may drain to a private onsite wastewater system, and the plumber will focus on the pipe from the house to that system. Permits follow the same split: unincorporated parcels go to Adams County, and annexed parcels go to the city they belong to.
Cost drivers
- Length and depth of the pipe from the house
- Driveways, outbuildings or trees along the route
- Whether a section can be repaired or the run replaced
- The right permit office for your parcel
- Any separate work on an onsite system, which is outside a plumber's pipe repair
When you call
You'll be connected with an independent local plumber who serves the Henderson area. Have your utility bill handy so you can say who provides sewer, if anyone. The plumber will usually clear the line, run a camera to find the defect and explain whether the fix is in your pipe or whether the utility needs to look at its side.
