A project to install tertiary filters at the Brushy Creek Regional Wastewater System East will be completed sometime next summer, Director of Utilities Michael Thane said.

The filters ensure that the treated waste water which discharges into Brushy Creek is within quality standards, Thane said. He said the system can filter 54 million gallons of water per day.

The gist

Round Rock City Council approved contracts with two companies July 25, furthering next steps in the project.

Plumber and Associates, Inc., a design engineering company, will do oversight for the installation of the filters, tying in a data system to monitor any flaws. Its services cost $561,000, with the city covering 60% of costs, or $314,000.


Keeley Construction Group, Inc. will install the tertiary filters, which will be encased in concrete boxes. The filters have been preordered and will arrive in September, when Keeley will begin construction.

The nine month contract costs $8.3 million, with the city responsible for 60%, about $5 million.

The additional costs will be taken on by other BCRWWS member cities, which include Austin, Cedar Park and Leander.

Looking ahead


With proper maintenance, the tertiary filters could last upwards of twenty years, Thane said. There are plans to add more filters in the future in the case of further expanding the wastewater treatment facility, he said.
