A new conveyor belt and rollers were installed on the belt press at Pilot Creek. Belt press begin running
again on 01/3/19.
Pilot Creek WWTP continues to operate the belt press as much as possible to remove metals in the
system(s). We are also trying to address the electrical issue at the plant in order to install mixers in the
basins. We will continue to operate the belt press in order to reduce the amounts of solids in the
system.
