Walnut Creek Wastewater Treatment Plant Headworks - 3023.019 - City of Austin

UPDATE : https://assets.austintexas.gov/budget/22-23/downloads/FY23_Proposed_Budget.pdf A detailed scope has not been determined. Project is included City of Austin FY 2023 Budget. Pg.No - 550. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- As of November 10, 2021, design is underway. Construction is scheduled to begin Summer 2024 and be completed Summer 2027. *The original solicitation is listed below for reference. --- The purpose of this project is to rehabilitate and make improvements to Headworks No. 1 (preliminary treatment) at Walnut Creek Wastewater Treatment Plant (WWTP). The mechanical and electrical components of Headworks No. 1 are original to the 1977 construction, and the majority are beyond their useful life. To prepare the plant for an interim peak flow capacity of 300 million gallons per day (MGD) and an ultimate peak flow capacity of 450 MGD, Headworks No. 1 will need modification. To achieve a headworks system peak flow capacity of 300 MGD, Headworks No. 1 will need to be modified to treat 75 MGD average and 150 MGD peak flow, with a 190 MGD wet weather flow (hydraulic) capacity.
