Alliance Water finds supply solutions for rapidly growing Central Texas

Alliance Regional Water Authority (Alliance Water) is a political subdivision of the State of Texas established to provide drinking water to satisfy the needs of three cities and one regional water authority located in Central Texas. The Alliance Water project will serve one of the fastest-growing communities in the country—one struggling to keep up with an increased demand for water.

Local water suppliers serving communities within the Austin-San Antonio corridor are facing a population expected to increase by 1.44 million by 2030. To keep up with demand and ensure clean water for future generations in the I-35 corridor between Austin and San Antonio, Alliance Water applied to the Texas Water Development Board for funding to develop groundwater supplies, provide water treatment, and build pipelines to multiple distribution points—providing a sustainable water supply for residents. The board required that the project meet certain environmental requirements spanning across agencies including the U.S. Fish and Wildlife Service, U.S. Army Corps of Engineers, Texas Parks and Wildlife Department, and Texas Historical Commission.  

As a full-scope partner, our team of experts worked with Alliance Water to conduct agency coordination and environmental investigations required to secure funding to implement this comprehensive treatment and transmission system. Before conducting extensive environmental site assessments, we coordinated with a wide variety of agencies to ensure compliance and sustainable development. This included everything from addressing historical and archeological cultural resources, to stream and wetland concerns and species protection. In addition to field work within approximately 85 miles of proposed transmission pipeline corridors, our team conducted environmental investigations for the proposed water treatment plant, booster pump station, elevated storage tanks, delivery points, and administrative and operations facility.  

Upon its completion, the Alliance Water project will bring potable water to a rapidly growing area along the I-35 corridor, supporting long-term growth in Central Texas. To successfully implement its multiple phases, we helped secure $288 million in funding from the Texas Water Development Board for the transmission pipeline, treatment plant, and associated facilities by working closely with Alliance Water, project engineers, and multiple federal, state, and local agencies.
