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.
Lift Stations
The City of Round Rock currently owns and operates 12 lift stations that pump wastewater to gravity sewer mains or to the Brushy Creek Regional Wastewater Treatment Plant.
Pretreatment
The City’s Pretreatment Program administers local, state and federal regulations to control pollutants discharged from Commercial and Industrial Users within the City, which may interfere with the City’s Publicly Owned Treatment Works. The Pretreatment Program protects the treatment process and keeps costs down by working with local businesses to minimize pollutant discharges. Click here for more…
