Reading the Lakeway data for plumbing

Lakeway is one of the most established suburbs tracked here — 19,027 people (2025 estimate), down just 0.9% since 2020^[2]. It covers 12.9 square miles (1,478 residents per square mile, the 12th densest), sits entirely in Travis County, in ZIP codes 78734, 78738^[3].

With 36% of homes built since 2010 and 14% before 1980^[1], Lakeway's plumbing runs from brand-new supply lines and fixtures to aging pipe, original valves and water heaters past their rated life.
