Comment: The facilitv is eauiDDed with two sludae storaae tanks (eauiDDed with mixers) and two belt
presses. One of the belt presses was not operational. Dewatered sludge is transported to
the on-site landfill (Cell #3) for disposal under the authority of Permit No. WQ0000537. No
sludge dewatering has occurred since October 2016 due to the low influent flow/loading to
the WWTP. All decant and filtrate are returned to the influent pump station.
