Walnut Creek Wastewater Treatment Plant – New Expansion – Austin, Texas

Owner: City of Austin | Austin Water
Contact Person: AECOM
Date Completed: December 2029 (est.)
Construction Cost: $700M (est.)
Project Description:

During the PER Phase assessments have been done on many of the structures that include: Aeration Basins, Chlorine Contact Basins, Primary and Final Clarifiers. Overall Purpose of the is to assist Austin Water in developing a plan to optimize current treatment processes, maximize existing and untapped treatment capacity, and identify strategic capacity additions or modifications that optimize site development of the Walnut Creek Wastewater Treatment Plant (WWTP) property while meeting the environmental, regulatory, social and financial requirements. The existing facilities at the plant are currently permitted for an average daily flow of 75 MGD and a peak flow of 165 MGD; however flows in excess of 200 MGD have been recorded at the plant. To address the peak flow condition in excess of current plant capacity, the recommended modifications first and foremost will address the 2-hour peak flow capacity at the existing plant. This will be achieved by maintaining the current average daily capacity of the plant at 75 MGD, but increasing the 2-hr peak flow capacity to 225 MGD, resulting in a 2-hour peaking factor of 3.0.
