Round Rock City Council will vote on a change order to bring the Brushy Creek Regional Wastewater System plant expansion up to date. The project began in 2020 and is about a year-and-a-half delayed, Director of Public Works Michael Thane said at a June 24 agenda packet briefing.

About the project

The BCRWWS plant expansion will bring the plant’s treatment capacity to 30 million gallons per day. The project is a regional collaboration between Round Rock, Austin, Cedar Park and Leander.

In a nutshell

The original contract with Thalle Construction amounted to $107 million, with Round Rock responsible for 12% of the regional expansion. According to Thane, the company had “lots of challenges,” including staffing and project management, which contributed to delays.


“They’ve had issues, but the team out there today we feel good about,” Thane said.

The fifth change order, on the agenda for Round Rock’s June 26 City Council meeting, has been in the works for about a year due to cost negotiations. The contract adds $1.3 million to the construction work, and Round Rock will be responsible for $157,334.

Looking ahead

If approved by City Council, Thane said the plant expansion will have a tentative completion date of this fall.


“We feel good about the direction we’re heading, and we see the finish line coming,” he said.
