Williamson County is taking a big step toward planning the water supply its growth will need. County commissioners on Oct. 20 approved a contract of almost $500,000 with engineering firm Freese and Nichols to create a countywide water infrastructure plan, Community Impact reported.
"It's a long time coming," County Judge Steve Snell said at the meeting.
What the study will do
The contract costs $498,700, and the work is expected to take about a year.
According to a county news release cited by Community Impact, the study will look at current and future sources of water in the county, along with treatment and distribution options. The goal is to come up with suggested projects that water providers can consider building.
Officials also said the study can help the county and its partners win state and federal funding for water projects, which would ease the tax burden on county residents.
"The price of water is so expensive these days," Snell said. "It's expensive to get the right, it's expensive to transport it, it's expensive to treat it, and I think we're seeing the price of water utility bills going up. This is an effort to have all of our partners together to save money on the cost."
How it got here
County officials first set up a regional water coalition in November 2025. It's an advisory committee with representatives from cities and water providers. According to county documents, the coalition has been meeting since then with the goal of hiring a consultant to begin the study.
The county does not sell water itself. Instead, officials said, it is working to help cities and utilities coordinate on buying water, planning infrastructure and conservation.
"It has been an incredible partnership with our cities and our water providers, and this is one giant step today ... to help secure the water of Williamson County for the people who are here today and identify new sources of water for our growth in the future," Snell said.
Precinct 3 Commissioner Valerie Covey pointed to the county's growth. "With the tremendous growth that we've experienced just over the last two decades and more to come, this is such an important issue, and a difficult issue, and an expensive issue," she said.
What comes next
With the contract approved, Freese and Nichols can start the study. If it stays on schedule, the plan should be finished in about a year. It will be up to the county's water providers to decide which of the suggested projects to pursue and when.
Because the county isn't a water provider, the plan won't build anything on its own. Its value will depend on whether the cities and utilities on the coalition agree on shared projects and work together to pay for them. Snell's comments suggest that cooperation is the whole point of the effort.
Why it matters for contractors
Water is one of the biggest limits on growth in Central Texas, and this study could shape years of infrastructure work in Williamson County. A countywide plan that covers water sources, treatment and distribution will likely point to new pipelines, treatment plant expansions, storage and pump stations. Those are major jobs for utility contractors, pipeline crews, concrete contractors and engineering firms.
The funding angle matters too. Officials said one purpose of the study is to help secure state and federal money for water projects. A finished regional plan can make projects more competitive for that money, and outside funding can help projects get built sooner.
For homebuilders and land developers, water supply affects where and how fast new neighborhoods can be built. A coordinated plan among cities and water providers could give builders a clearer picture of where service will be available down the road.
This is a planning contract, not a construction contract, so the building work is still at least a year out. But contractors who work in Williamson County should keep an eye on this study. The project list it produces could become the region's water construction pipeline for years to come.
