The proposed expansion will double the extended aeration treatment facility currently in place. The proposed technology (i.e. oxidation ditch) is well developed and suited for Heber. The scope of the project involves the construction of an oxidation ditch identical to that currently in operation at the plant. Additional work items include improvements to the headworks, additional pumping capacity, two new clarifiers, improved sludge drying, larger discharge lines and a disinfection system.
