Water Supply
LCRA Supplies Raw Water to Several Williamson County Communities
The Lower Colorado River Authority is authorized to transfer up to 25,000 acre-feet of water annually into Williamson County under a state law.
Williamson County has grown fast. That growth has strained local water supplies. To help meet demand, state law allows the Lower Colorado River Authority (LCRA) to bring up to 25,000 acre-feet of raw water into the county each year. One acre-foot is roughly what a typical family uses in a year.
The law requires that this transfer cause no net loss of water to the lower Colorado River basin. The LCRA delivers raw, untreated water. Local water utilities — cities, MUDs (water districts), and water supply companies — then treat and send it to homes and businesses.
If you are buying a home or land in Williamson County, ask which utility serves your property. Ask what their long-term water supply agreements look like. It matters more in fast-growing areas where demand keeps rising.
