City of Gatesville

The City of Gatesville’s Stillhouse Branch Wastewater Treatment Plant (WWTP) is beginning to experience flows and loads that trigger the need to start plant expansion plans. John Winkler, PE of Walker Partners, designed the original plant in 1989.

Walker Partners is working with the City of Gatesville to obtain State Revolving Funds (SRF) from the Texas Water Development Board (TWDB) for the plant expansion. We are coordinating and submitting the major amendment to the WWTP’s TPDES Permit to TCEQ.

The WWTP is an extended aeration facility currently rated for 2.2 MGD. Walker Partners completed a process evaluation and capacity rerate that supports an expansion without causing more restrictive permit limits and higher construction costs. This defers approximately $2 - $3 million dollars in expenditures for the City.
