What Smyrna's numbers say about plumbing
Smyrna counts 57,513 residents (2025 estimate), growing at a middle-of-the-pack 2.4% since 2020[2]. It covers 16.2 square miles (3,554 residents per square mile, the 3rd densest), sits entirely in Cobb County, in ZIP codes 30080, 30082, 30126[3].
With 15% of homes built since 2010 and 28% before 1980[1], Smyrna's plumbing runs from brand-new supply lines and fixtures to aging pipe, original valves and water heaters past their rated life.
