Round Rock City Council approved a $1.5 million contract March 28 with Walker Partners Engineers and Surveyors for the final design of the Phase 2A expansion of the Brushy Creek Regional Water Treatment Plant, servicing Round Rock, Cedar Park and Leander.

Two-minute impact

This phase of expansion to the BCRU treatment plant will increase the facility's total capacity to 64 million gallons per day.

Construction is currently underway for a previously approved Phase 1D expansion of the water treatment plant, expanding treatment capacity from 32.5 million gallons per day to 41.9 million gallons per day. Phase 1D of expansion predominately benefits the city of Cedar Park, while Phase 2A will benefit Leander and Round Rock.

The following is a breakdown of the cities benefiting from Phase 2A:
  • The city of Leander will receive an additional 11.7 million gallons per day.
  • The city of Round Rock will receive an additional 10.6 million gallons per day.

Phase 2A will increase the city of Round Rock’s overall capacity to nearly 22 million gallons per day, Director of Utilities Michael Thane said.

Construction is expected to begin in 2025 and be completed by summer 2027—the same time city's the deep water intake project will be completed in Round Rock.

“This will be really big for Round Rock—to get us out ahead [and] to have that extra treatment plant capacity that we need as our city continues to grow,” Thane said.

After a preliminary assessment by the engineering company, the full scope and cost of the work was determined. The total agreement with Walker Partners will total just over $3 million, with Round Rock paying just over one-third of the cost for the expansion project.


Funding for this phase of the project comes from the city of Round Rock’s regional water fund. However, the agreement will need to go before all three city councils for final approval.
