Austin's water, with the same chloramine
Water District 10's 2025 report shows chloramine at an average of 2.22. Hardness averaged 102 ppm, about 6 grains per gallon. That's moderately hard, and softer than most of the suburbs.
Fluoride averaged 0.65 ppm, since Austin's supply is fluoridated. The report also lists low level PFAS detections, carried over from testing on the supply.
What most Westlake homes do
With moderate hardness, the main complaint here is usually taste and smell from chloramine. A whole house catalytic carbon filter plus RO for drinking water covers most homes. A softener is optional.
Westlake neighborhoods
Coverage includes Westwood, Rolling Hills West, Knollwood, Westlake Highlands, Camelot, Rob Roy, and the rest of West Lake Hills. Homes outside the city in the wider Westlake area may be on a different provider, so check your bill.
