2 BCRUA maintenance building
5 Proposed piping connection
A project to pull water from the deepest locations of Lake Travis to supply the BCRUA—a partnership made up of the cities of Round Rock, Leander and Cedar Park—is roughly halfway complete. Once completed, the BCRUA’s raw water intake project will have the capacity to pump 145 million gallons of raw water from the lake per day. The project is meant to help the three cities meet future water demands by providing a stable source year-round. Phase 1 of the project included the construction of a oating barge and raw water system on Lake Travis, pulling roughly 32 million gallons of water per day from the lake. However, o cials say the barges are susceptible to drought conditions. “These projects re ect [Cedar Park’s] ongoing commitment to proactive water planning,” Sousa said.

Water distribution for Phase 2 of the BCRUA’s Raw Water Intake project The member cities of the BCRUA will each contribute funding for the new project, proportional to the amount of water each city will receive.

The localities participating in the regional partnership originally met in 2006 to determine how much water each city would need at full build-out. The deep water intake project, which began construction in 2022, includes the con- struction of a 2-mile pipeline delivering water from intake screens to a new pump station. A raw water transmission tunnel and pipeline will move the pumped water to existing Cedar Park, Leander and BCRUA water treatment plants. Michael Thane, executive director of public works for the city of Round Rock, said the com- bination of BCRUA projects, along with its other sources, secures Cedar Park and neighboring cities’ water well into the future. “This will take us a long way out there—prob- ably around 2070 and 270,000 customers,” he said. “So we have water under contract that can meet our demands for the next 45 years.” In 2022, the BCRUA approved a contract with Thalle Construction Co. and SAK Construction for $224.8 million to build the intake system. The total cost is estimated at $293 million and is funded with cash contributions and contract revenue bonds, according to the BCRUA.
Lakes Travis and Buchanan serve as the primary water supply reservoirs in the Highland Lakes system. The last time both lakes were full was July 2019, according to the Lower Colorado River Authority. As of April 15, the lakes combined were 48% full. The Central Texas Water Coalition is an organization dedicated to protecting the water resources of the Highland Lakes. The CTWC calls for increased conservation and planning measures in light of histori- cally low in ows into the lake, which the organization attributes to thousands of unregulated upstream ponds, Executive Director Shannon Hamilton said. “Whether we like [the pipeline] or not, it’s coming online. We just have to plan for it,“ Hamilton said. “We’re just not getting the same amount of water that we used to get for the same amount of rainfall. ... I don’t know when another rain event is coming, but I do know that we’ve got a lot of people relying on our lakes, and this is what we have today.”
