Water filtration in Liberty Hill
Liberty Hill has grown fast, and its water system has grown with it. Most of the city's water is Lake Travis water treated at Leander's Sandy Creek plant. The rest comes from eight city wells in the Trinity Aquifer.
The city also buys water from Georgetown.

Chloramine and a mixed supply
Liberty Hill disinfects with chloramine, averaging 1.29 mg/L in 2025. The report doesn't publish a hardness number. Lake Travis water elsewhere in the area runs very hard, and Trinity Aquifer groundwater is typically hard too, so test before you buy.
Other notes from the 2025 report
The report lists combined radium at 3.43 pCi/L, under the federal limit of 5, and a 90th percentile lead result of 2.11 ppb. It also notes monitoring and reporting violations in 2025, which the city says were reporting errors.
