Water filtration in Lakeway
Lakeway sits right on Lake Travis, and that's where its water comes from. But not everyone in the area gets it from the same utility.
Most of Lakeway is on Lakeway Municipal Utility District. Nearby areas like Steiner Ranch, Flintrock, and Serene Hills are on Travis County WCID 17. Both report very similar water.

WCID 17 treats Lake Travis water with membrane filtration. Its 2025 report puts hardness at 182 to 185 ppm, about 10.7 grains per gallon, and chloramine at an average of 2.42 ppm. WCID 17 adds fluoride.
