It also included reinstalling new air mixture systems to improve and meet EPA standards. The 2nd stage included a new nitrification system and replacing four existing sluice gates along with replacing existing aeration piping with a redesigned header system from below grade to above grade requirements. Additional work was done on the concrete foundation of the auxiliary basin to reinforce the structure.
