Centennial does not run its own sewer system; several separate sanitation districts do, depending on where you live. Whatever the district, a camera inspection of the line leaving your house shows whether roots, a crack, a low spot or buildup is causing backups. Call the number on this page to be connected with a local plumber in Centennial.
Who handles sewer in Centennial
The City of Centennial incorporated in 2001 from unincorporated Arapahoe County, and water and sewer stayed with the special districts that already served those neighborhoods. The city's sanitation districts map lists Castlewood Water and Sanitation District, Southgate Sanitation District, the Arapahoe County Water and Wastewater Authority (ACWWA), South Arapahoe Sanitation District, Havana Water and Sanitation District, East Cherry Creek Valley Water and Sanitation District and South Englewood Sanitation District No. 1. Your bill names yours. In the Southgate area, the district's rules make the owner responsible for the private service line, and Southgate takes water break and sewer backup calls at 303-779-0261. Other districts set their own rules, so ask yours if a problem appears near the main.
Centennial is mostly residential, split by I-25, with rolling hills and ravines. Laterals that run downhill across a sloped lot or near a drainage can be affected by soil movement, and mature landscaping along older streets near Southglenn and the High Line Canal Trail can send roots toward joints.
Choosing the right first step
| Situation | Reasonable first step |
|---|---|
| One fixture slow, rest fine | Clear that branch; camera usually not needed |
| Whole house backing up, neighbors fine | Clear the main, then camera the lateral |
| Neighbors backing up too | Call your sanitation district first |
| Buying a home | Camera inspection during the inspection period |
| Repeat clogs after clearing | Camera to find the cause before paying for another clearing |
Warning signs
- A lower-level shower or floor drain takes on water during laundry
- Toilets gurgle after other drains run
- Several drains slow down together
- Sewer smell indoors or near the cleanout
- Wet, unusually green strips over the line's route
Timing notes
Roots are most active in spring and summer, which is often when an older lateral starts backing up. Do not wait for a full backup if drains have been slowing for weeks; a partial blockage is easier to clear and film. If footage shows a repair is needed, the City of Centennial Building Division requires a permit for any work on plumbing systems, and the plumber doing the work typically handles the application.
