What Centennial's numbers say about plumbing

Centennial is one of the most established suburbs tracked here — 108,658 people (2025 estimate), up just 0.6% since 2020^[2]. The city spans 30.2 square miles at 3,603 residents per square mile (the 7th densest) and sits entirely in Arapahoe County, served by ZIP codes 80112, 80122, 80016, 80015, 80121^[3].

With 7% of homes built since 2010 and 43% before 1980^[1], Centennial's plumbing runs from brand-new supply lines and fixtures to aging pipe, original valves and water heaters past their rated life.

Centennial is split across 5 ZIP codes: 80112 (27% of the city's land), 80122 (22% of the city's land), 80016 (18% of the city's land), 80015 (14% of the city's land), 80121 (11% of the city's land)^[6].

The closest tracked neighbours are Parker (7.5 mi SE), Englewood (8.0 mi NW) and Littleton (8.3 mi W)^[3].

43% of Centennial's 43,291 housing units predate 1980 and 7% went up in 2010 or later^[1] — the 7th-highest pre-1980 share of the 15 Denver-area suburbs we cover; nearby, Parker (3%), Englewood (68%), and Littleton (46%) predate 1980. The 43% built in 1980–1999 are at the age where original water heaters and valves get replaced.

The biggest single slice — 28% — was built 1970 to 1979, and the median home dates to 1983^[1]. Neighbours from the same era tend to hit the same plumbing problems at the same time.

Water from the sky is plumbing work too: 8 flood or flash-flood reports within 10 miles over 2016–2025^[4], and FEMA logged 54 flood-insurance claims across Centennial's ZIPs^[5]. Homes that take water need working drainage, sump pumps and backflow prevention.

77% of homes heat with utility gas, and 19% of households rent^[1].

Measured against the 15 suburbs on this site, Centennial records the lowest renter share (19%)^[1], the 2nd-lowest share of homes built since 2010 (7%)^[1], and the 2nd-highest gas-heat share (77%)^[1].
