May 31, 2024
The Austin City Council on Thursday approved more than $1 billion in contracts to upgrade and expand the Walnut Creek Wastewater Treatment Plant in East Austin.
The plant is one of Austin Water's two major facilities that treat wastewater from the city's sanitary sewer collection system before sending it back into the Colorado River, according to the city of Austin.
The Walnut Creek Wastewater Treatment Plant has been expanded since it was first built in 1977, and it is currently authorized to treat and discharge an average of 75 million gallons per day, according to a May 24 memo from Austin Water Director Shay Ralls Roalson to the mayor and City Council.
