Dothan-city leaders have approved plans to close a waste treatment plant in order to double the size of another.
Commissioners approved to give almost 3-million dollars to the project which will eventually lead to a larger project that will cost between 30 and 35-million dollars.
Federal government authorities said the water flow at Beaver Creek needed to be lowered to improve water quality.
One plant will be de-commissioned while the capacity of another will be doubled.
Leaders say they have not totally excluded using some of the sales tax increase to fund the project.
