The City of San Luis Obispo is expected to break ground this fall on improvements to its Water Resource Recovery Facility.
Last week, the city council awarded a more than $110 million construction contract for the project to PCL Construction.
The current plant off Prado Rd. was constructed in 1923 and has been upgraded or expanded multiple times over the years.
This new project is designed to improve overall operations, reduce the need for chemicals in the water treatment process, optimize energy use, and reduce odor and noise impacts to neighbors. City officials say it will also enhance water quality in San Luis Obispo Creek.
New additions include a membrane bioreactor (MBR) and ultraviolet (UV) disinfection system, which are scheduled to be in service by December 2021. The entire project is expected to be completed by the summer of 2023.
The project will also reportedly include new digesters, an odor control system, flood protection improvements, an upgraded electrical system, and other improvements.
The city says much of the cost of construction is being offset by grants and low-interest loans from the state.
