Title
Discussion and update regarding the Wilbarger Creek Regional Wastewater Treatment Facility Project.
Summary
This presentation is to give an update regarding the progress of this project.
Background
The City’s wastewater service area includes three basins, the Central, Wilbarger, and Cottonwood basins. Currently, lift stations and pumping infrastructure is in place to convey wastewater flows across basins to the Central Wastewater Treatment Plant (WWTP).
The adopted 2020 Wastewater Master PIan recommended the City proceed with improvement projects in the Wilbarger Basin to provide conveyance of wastewater from the Wilbarger and Cottonwood basins to a new wastewater treatment plant in the Wilbarger Basin. The updated 2020 Wastewater Master Plan indicates that these improvements will need to be substantially completed and in service by December 2024 to meet the City’s projected growth needs.
The property, approximately 159 acres, for the proposed Wilbarger Creek Regional Wastewater Treatment Facility was purchased for this purpose in 2009 and is owned by the City of Pflugerville. The tract of land is located off of Gregg Lane between Fuchs Grove Road and FM 973. A permit was approved by the Texas Commission on Environmental Quality (TCEQ) (Permit NO. WQ0011845005 (EPA I.D. No. TX0132021)) on 10/2009 to authorize the discharge of treated wastewater at a volume not to exceed an annual daily flow (ADF) of 15.75 million gallons per day (MGD) and a peak 2-hour flow of 43,750 gallons per minute (GPM) (63.0 MGD). The discharge permit included Interim permit flow limits as follows: Interim 1 - 2.0 MGD ADF and Interim II - 4.0 MGD ADF. The discharge route is from the plant site via a pipeline to Wilbarger Creek, then to the Colorado River.
