That's after Wichita Falls city councilors approve a large rehabilitation project at the plant.
City officials say workers will replace the digester tops on the equipment that receives the sludge for treatment and decomposition.
The project will cost about $3.6 million dollars.
Officials say it's a project that needs to be done, and it will improve the overall efficiency of the plant.
Russell Schreiber, Wichita Falls public works director, says, "There are a lot of corrosive environments in that plant. Materials just wear out. These digester tops are basically deteriorated and need to be replaced."
Officials say the project should be complete in about 540 days.
The plant will remain in operation while construction is going on.
Schreiber says the project is a step-by-step process, and workers will have to take one digester off-line at a time while it's being repaired.
Once that digester is good to go, workers will repair the next digester.
