This morning, crews used this crane to hoist a large cover on top of one of the plant's digestors.
That's where all the waste material that comes in the sewage is decomposed.
Officials say the cover will contain the decomposition process, keep it hot, and will collect the product gas that's generated.
Daniel Nix, city utility operations manager, says, "Our hopes are in the next couple years that we will start generating enough methane that we will generate electricity with it and power some of the waste water plant with that electricity."
Nix says the digestor's old cover was corroded and had trace amounts of methane gas escaping, which was a safety concern.
He says as soon as the digestor is in full operation, crews will work on the next one.
This project will cost the city just more than $3.5 million and will take about a year-and-a-half to complete.
