Henderson is a patchwork of unincorporated Adams County land and parcels annexed by Commerce City, Brighton and Thornton, so the sewer provider varies by address. What doesn't vary is that the drains inside your home and the line leaving it are private plumbing. Call the number on this page to be connected with a local plumber in Henderson.

Signs a drain needs a plumber
- Water standing in the tub or shower well after use
- A toilet that bubbles or rises when another fixture drains
- The kitchen sink filling when the dishwasher pumps out
- Wastewater at the lowest drain in the house
- A sewage smell that won't go away
One slow fixture means a nearby clog. Several slow fixtures, or water appearing at the lowest drain, means the main line, and you should stop using water until it's cleared.
The Henderson picture
Henderson is a small unincorporated Adams County community with a post office dating to 1894 and a few older buildings along Brighton Road north of 120th Avenue. Much of the surrounding area has been annexed by Commerce City, Brighton and Thornton, and with annexation comes a different set of utilities and permit offices. Which provider handles water and sewer at a Henderson address could not be determined from public sources; it depends on whether the parcel is annexed and which district's lines serve it. South Adams County Water and Sanitation District's Williams Monaco Wastewater Treatment Plant sits on Monaco Street in Henderson, but that alone doesn't mean every nearby home is on its sewer.
The honest answer is to check your bill. If you pay a sewer charge, the name on it is your provider. If you don't, your home may not be on municipal sewer, in which case its drains lead to a private onsite wastewater system and a plumber's work stops at the line to it.
What drives the cost
- Clog location: a fixture trap or the main line toward the street or onsite system.
- Access: an existing cleanout saves time.
- Method: hand auger, machine cable or water jetting.
- Diagnosis: a camera inspection for repeat problems.
- Repair: broken or root-filled pipe means more than cleaning.
- Timing: after-hours visits generally cost more.
