Collection System

The City of Round Rock’s wastewater collection system is made up of over 300 miles of collection lines.  These lines ultimately go to the Brushy Creek Regional Wastewater Treatment Plant either directly or through larger diameter regional interceptor lines.  The Brushy Creek Regional Wastewater Treatment System is jointly owned and operated by the Cities of Round Rock, Cedar Park and Austin.  The City of Round Rock has a collection system rehabilitation program that includes cleaning and videoing the collection system, as well as inspecting and correcting “problem” areas that require regular maintenance. This program is funded through water and wastewater utility funds.

Surcharge and Grease Program

The purpose of the City’s surcharge program is to reduce excess amounts of solids and oxygen demanding substances from entering the wastewater system.  Solids and fats, oils and grease (FOGs) can clog the sewer lines, cause sanitary sewer overflows and put a heavy operational load on the wastewater treatment plant.
