AECOM Leads Expansion of Walnut Creek Wastewater Treatment Plant
AECOM (NYSE: ACM), a prominent global infrastructure consulting firm, has been chosen as the main consultant by the City of Austin for a major upgrade of the Walnut Creek Wastewater Treatment Plant (WWTP). This project aims to improve both the operational efficiency and environmental impact of the facility, boosting its capacity from 75 million gallons per day (MGD) to an impressive 100 MGD. As Austin’s population keeps increasing, these upgrades will not only enhance the wastewater infrastructure but also protect the surrounding ecosystem.
Building Partnerships for Sustainable Solutions
Beverley Stinson, the CEO of AECOM’s global Water business, shared her excitement about the ongoing partnership with the City of Austin. "Being the industry’s leading Water consulting firm, we are dedicated to providing advanced treatment capabilities to the community," said Stinson. The firm has significant experience in efficient nutrient removal technologies, a key factor for boosting plant performance and improving the quality of the treated water to protect the environment.
Engineering Scope and Innovations
This project includes a comprehensive range of engineering services, such as process, mechanical, civil, electrical, and structural engineering, aimed at modernizing existing infrastructure. Major components of the expansion involve replacing outdated equipment, building a new 25 MGD treatment train, and developing a new 120-inch outfall line. Additionally, the project will provide wet weather treatment capabilities using advanced 100 MGD cloth filters and a flood wall, built according to the National Weather Service’s historic flood risk study.
A Commitment to Austin’s Development
Matt Crane, CEO of AECOM’s U.S. West region, pointed out the firm’s long-standing relationship with the City of Austin, highlighting their involvement in designing key water and wastewater treatment systems over the years.
