Reading the Eagan data for plumbing

Eagan is one of the most established suburbs tracked here — 67,109 people (2025 estimate), down just 2.5% since 2020^[2]. It covers 31.2 square miles (2,152 residents per square mile, the 11th densest), sits entirely in Dakota County, in ZIP codes 55122, 55123, 55121^[3].

With 10% of homes built since 2010 and 25% before 1980^[1], Eagan's plumbing runs from brand-new supply lines and fixtures to aging pipe, original valves and water heaters past their rated life.

3 ZIP codes cover Eagan — 55122 (35% of the city's land), 55123 (35% of the city's land), 55121 (31% of the city's land)^[6].

The closest tracked neighbours are Apple Valley (5.2 mi S), Burnsville (6.7 mi SW) and Bloomington (7.5 mi W)^[3].

25% of Eagan's 28,789 housing units predate 1980 and 10% went up in 2010 or later^[1] — the 5th-lowest pre-1980 share of the 15 Twin Cities–area suburbs we cover; nearby, Apple Valley (30%), Burnsville (45%), and Bloomington (67%) predate 1980. The 56% built in 1980–1999 are at the age where original water heaters and valves get replaced.

The biggest single slice — 34% — was built 1980 to 1989, and the median home dates to 1988^[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: 11 flood or flash-flood reports within 10 miles over 2016–2025^[4], and FEMA logged 15 flood-insurance claims across Eagan's ZIPs^[5]. Homes that take water need working drainage, sump pumps and backflow prevention.

81% of homes heat with utility gas, and 32% of households rent^[1].
