The City of Centennial does not run sewer service; several sanitation districts do, so the public side of your line depends on the address. The drain pipes in the house and the service line to the district's main are private, and that is where a plumber works. Call the number on this page to be connected with a local plumber in Centennial.
Who handles sewer in Centennial
The city's sanitation district map lists Castlewood Water and Sanitation District, Southgate Sanitation District, the Arapahoe County Water and Wastewater Authority, 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 the one that serves you. Southgate, for example, handles sewer backups on its side at 303-779-0261.
This matters when the main is in question. If a plumber clears your line and it runs freely to the property edge, but sewage still comes back, the district should hear about it. For a single slow sink or a toilet that clogs, the district is not involved at all. Drain materials depend on when a house was built, from cast iron to plastic, so a plumber will ask about the age of yours before choosing equipment.
Choosing a method
| Problem | Typical approach | Notes |
|---|---|---|
| One fixture slow | Hand auger at the trap or branch | Quickest and least invasive |
| Whole house slow or backing up | Main line machine through a cleanout | A cleanout saves pulling a toilet |
| Grease or repeat clogs | Water jetting | Scours the pipe wall clean |
| Unexplained repeat backups | Camera inspection | Shows roots, sags or breaks |
Signs to take seriously
- Water backing into a tub when a toilet flushes
- A gurgle from the kitchen sink every time the dishwasher drains
- Wet carpet or a puddle near a basement floor drain
- Sewage odor that returns after you clean the drain
- Plunging that works for a day and then fails again
Timing notes
Where a Centennial lot has mature trees, roots grow toward sewer joints over the years. A main line that slows every year or two is worth a camera look after cleaning. Around holidays, kitchen lines handle more grease than usual; scrape plates into the trash and run the disposal with plenty of cold water. If a repair is needed, the City of Centennial requires a permit for any work on plumbing systems, and the Building Division issues it. If you are repairing a line under a driveway or landscaping, ask the plumber whether trenchless options fit your pipe before anyone starts digging.
