Centennial does not run its own water utility; several special districts serve the city, so who owns which part of the service line depends on your address. A plumber can confirm the leak, locate it and tell you whether it sits on your side. Call the number on this page to be connected with a local plumber in Centennial.

Water service in Centennial
The City of Centennial says water and sewer come from several different water and sanitation districts, and much of the city's water arrives through Denver Water distributors. The city's district map lists Southgate, Willows, ACWWA, Castlewood, East Cherry Creek Valley, Havana, Inverness and others. Your bill names the district that serves you, and that district's rules decide where your responsibility begins.
Southgate is a good example. In its area, the property owner is responsible for maintaining, repairing and replacing the service line on the owner side of the curb stop, owns the meter and is responsible for the meter pit. Southgate will repair leaks between the main and the edge of the public right-of-way on written request. Willows and the other districts have their own rules, so check with yours before digging in the yard.
Where the leak is and what the fix usually looks like
| Leak location | How it shows up | Typical repair |
|---|---|---|
| Owner-side service line | Wet lawn between the curb and the house | Spot repair or a new run of line |
| Meter pit | Water standing in the pit | Depends on district rules; in Southgate's area the pit is the owner's |
| Slab or basement floor | Warm floor, damp carpet | Reroute or open a small section |
| Wall or ceiling | Spreading stain, soft drywall | Replace a fitting or short pipe section |
| Irrigation | One zone that never dries | Replace the valve or cracked line |
Signs to take seriously
- Your district bill shows more gallons with no change in habits
- The meter's leak indicator turns with the house silent
- You hear water moving in a wall at night
- A toilet refills on its own every so often
- Paint blistering near a tub or along a baseboard
Timing and seasons
Hard freezes and quick Front Range temperature swings are hard on exterior hose bibs and pipes in outside walls, and a split often shows up only when the weather warms. Spring irrigation start-up is the other common time a leak appears. Any repair that touches plumbing needs a permit from the City of Centennial Building Division, which requires one for all plumbing and gas work, and the plumber can handle that step.
