Centennial doesn't run its own sewer; several sanitation districts serve the city depending on the address. The private line from your house to the district main is a plumbing repair, and the City requires a permit for any plumbing work. Call the number on this page to be connected with a local plumber in Centennial.
Centennial's sanitation districts
Centennial, incorporated in 2001 from unincorporated Arapahoe County, gets water and sewer from a collection of special districts instead of a city utility. 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. Southgate, for example, takes calls about sewer backups at 303-779-0261. The district on your bill is the one to call if the public main might be involved.
The City of Centennial Building Division requires a permit for any work on plumbing systems, so a sewer line repair beyond simple clearing will involve a permit and inspection. The division is at the Civic Center on East Arapahoe Road, 303-754-3321.
Repair options compared
| Method | When it fits | Trade-offs |
|---|---|---|
| Spot repair | One cracked joint or short broken section | Single excavation; the rest of the pipe stays as is |
| Cured-in-place liner | Pipe still holds its shape but leaks or has root entry | Little digging; needs good access and a round pipe |
| Pipe bursting | Long run of failing pipe with a clear path | Pulls new pipe through the old; small pits at each end |
| Open-trench replacement | Collapsed pipe, severe sags, or changes in route | Most disruption; full control over slope and bedding |
Signs it's time to call
- A basement floor drain backs up during laundry
- Gurgling in toilets when tubs drain
- Several fixtures slow on the same day
- Clogs that return within weeks of snaking
- Odor or a damp strip in the lawn along the sewer route
Timing and seasons
Root intrusion tends to show up as roots grow through the warm months, and repeat clogs often follow. Cold snaps push frost deeper, and soil movement from freezing and thawing can work an already weak joint open. Fall is a practical time to have a line inspected if it has given trouble, before the ground freezes and excavation gets harder. If water is backing up now, don't wait for a better season; stop using fixtures and call.
