Centennial is served by several water and sanitation districts rather than one city utility, so where your private water line begins depends on your district. When leaks keep recurring or flow has faded through the house, a plumber can replace the supply lines with PEX or copper. Call the number on this page to be connected with a local plumber in Centennial.

Local conditions
Centennial incorporated in 2001 from unincorporated Arapahoe County, but many of its neighborhoods are much older than the city itself. The fact sheet for Centennial does not include a reliable year-built breakdown, so it is hard to say how much of the housing still has original pipe. In practice, the age of your own house and what you can see at the water heater are the best guides.
Water and sewer come from separate special districts. The city's district map lists Southgate, Willows, Arapahoe County Water and Wastewater Authority, East Cherry Creek Valley, Inverness, Castlewood and others, and much of Centennial's water arrives through Denver Water distributors. Responsibility for the service line varies by district. In Southgate's area, for example, the owner is responsible for maintaining, repairing and replacing the service line on the owner side of the curb stop and for the meter pit. Your water bill names your district, and the district office can tell you where its responsibility ends before anyone digs near the meter.
Repair, partial repipe or full repipe
| Option | Best fit | Trade-off |
|---|---|---|
| Fix one leak | Sound pipe with a single bad joint | Does nothing for the rest of an aging system |
| Replace one zone | A single bathroom group or one failing material | Older pipe elsewhere stays in service |
| Whole-house PEX | Most full repipes in finished homes | Fewer wall openings, quicker install |
| Whole-house copper | Owners who prefer rigid metal lines | More fittings and labor time |
Signs to watch
- Small leaks turning up in different parts of the house
- Greenish stains or white crust at copper joints
- Low pressure at several fixtures that aerator cleaning does not fix
- Discolored water when a tap is first opened
- A water bill rising without any change in use
Timing and permits
The City of Centennial Building Division requires a permit for any work on plumbing systems, so a repipe will be permitted and inspected. Spring through early fall is the easiest window, before freezing nights put extra strain on old pipe in exterior walls. If a kitchen or bath remodel is already planned, that is a practical time to replace nearby lines while walls are open.
