Workshop Memorandum 18-003



                Date:          January 9, 2018

                From:          Joseph Zoba, General Manager

                Subject:       Evaluation  of  Existing  Belt  Press  Equipment  at  the  Wochholz  Regional  Water
                               Recycling Facility

               The    Wochholz     Regional    Water
               Recycling  Facility  uses  belt  filters  to
               remove  liquids  from  the  biosolids
               collected   throughout    the   sewer
               treatment  process.    The  belt  filter
               technology  has  been  in  use  at  the
               sewer  treatment  plant  for  over  twenty
               years and have proven to be a simple
               and reliable technology that has been
               easy to maintain with a long life.

               As  this  equipment  has  surpassed  its
               useful life the District staff has noticed
               signs of metal fatigue and stress cracks
               in the equipment.  Therefore, we have
               started  to  process  to  evaluate  other
               available  technology  to  plan  for  the
               replacement  of  the  existing  belt
               presses.

               However, prior to initiating the construction of the alternative  dewatering equipment to further
               reduce maintenance, energy and hauling costs, maintenance on the existing equipment will be
               needed to be completed.
