Henderson is an unincorporated Adams County community, but much of the surrounding area has been annexed into Commerce City, Brighton and Thornton, so the water provider and the permit office depend on the exact address. Unincorporated parcels get permits from Adams County. Call the number on this page to be connected with a local plumber in Henderson.

Signs your Henderson property needs a plumber
- Floor drains in a shop, barn or warehouse that hold water
- Restroom fixtures that run or leak
- Wet ground between the meter and the building
- A water heater that can't keep up with a work crew
- Sewer smell near a cleanout or floor drain
- A backflow device that hasn't been tested in a while
Sorting out utilities and permits in Henderson
We couldn't confirm a single water or sewer provider for Henderson, and that's the honest answer. Annexed parcels may be served by Commerce City's provider, South Adams County Water and Sanitation District, or by Brighton or Thornton. Hazeltine Heights Water and Sanitation District, a small domestic water district with a Henderson mailing address and a well house on East 104th Avenue, serves some customers; it makes customers responsible for the line from the downstream side of the meter pit to the building and for any required backflow devices. SACWSD's Williams Monaco wastewater plant sits on Monaco Street in Henderson, but that doesn't tell you whether a given building is on its sewer.
The quickest way to know is the water bill, or the sewer bill if there is one. If you have neither, Adams County can tell you whether the parcel is unincorporated or inside a city.
Permits follow the same split. In unincorporated Adams County, the One Stop Permitting Center and Building Safety at the Government Center in Brighton, 720-523-6800, require a permit to install or replace a water heater and for plumbing modifications, and contractors must be registered with the county. Annexed parcels go to Commerce City, Brighton or Thornton instead. The gas utility wasn't verified for Henderson either, so check the gas bill for the name and emergency number.
What affects the cost
- The type of property, from a small shop to a warehouse or fairground building
- Distance between the meter and the building and whether digging is needed
- Backflow devices that need repair or replacement
- Access to drains, cleanouts and heaters
- County or city permits and inspections
