The Austin City Council has approved a $1 billion plan to enhance and expand the Walnut Creek Wastewater Treatment Plant, according to a city news release.
Construction is scheduled to begin in 2025. The plan aims to add an additional treatment capacity of 25 million gallons per day to accommodate population growth. Currently, the plant treats 75 million gallons per day.
“With these investments, every part of the treatment process will be enhanced and upgraded, preparing us to meet the growing needs of our city,” said Austin Water Director Shay Ralls Roalson.
The project also includes replacing the plant’s current disinfection system and constructing a wall around the plant to protect it from potential flooding.
