Plumbing Service Areas: Centennial and 13 Nearby Towns

The city of Centennial itself uses 80015, 80016, 80111, 80112, 80121, 80122, 80155 and 80161. Those eight codes are listed first because they surround the dispatch address, and the table after them gives every code for every area page.

Postal codes cross town lines, so none of them belongs to a single page. For example, 80111 appears on the Englewood and Greenwood Village pages; 80112 appears on the Englewood and Castlewood pages; 80121 appears on the Littleton, Greenwood Village and Southglenn pages; 80122 appears on the Littleton and Southglenn pages; 80123 appears on the Littleton and Columbine pages; 80126 appears on the Highlands Ranch and Littleton pages; 80128 appears on the Littleton and Columbine pages; 80129 appears on the Highlands Ranch and Littleton pages; 80130 appears on the Highlands Ranch and Littleton pages; 80134 appears on the Parker, Pinery and Saddle Brook pages; 80138 appears on the Par. Give the dispatcher your street address rather than only a ZIP code, and the call can be matched to the right part of the map.

No single utility supplies all of Centennial. The city's utilities page says Denver Water distributors carry much of the supply, and its district map also names ACWWA, East Cherry Creek Valley and Castlewood. Southgate Water and Sanitation Districts serves residents in Arapahoe and Douglas counties. Your water bill shows which one applies to your address.

Permits depend on location too. The dispatch network crosses Arapahoe, Douglas and Jefferson counties, and an address inside a city answers to that city's building office while an unincorporated address answers to its county. A water heater swapped for the same type of unit goes through Centennial's quick one-stop permit track, reviewed within a business day. The State Plumbing Board adds that water heater work calls for a licensed plumber plus a permit and inspection.
