INTEROFFICE MEMORANDUM
Date: December 7, 2018
To: The Honorable Mayor and City Council
Through: Harvey Robinson, Interim City Manager
From: Donald G. Stanton, Assistant Director of Utilities
RE: PR 20424—Centrifuge Repair at the Water Treatment Plant
Introduction:
The intent of this Agenda Item is to seek City Council's Ratification for the Emergency Repair
for the repair of a centrifuge for sludge removal. Andritz Separation, of Pittsburg, Texas, was
chosen to do the repairs in the amount of$51,450.00. Budgeted funds are available in account
#410-1252-532.42-00. Emergency authorization from the City Manager was sought due to the
critical nature of sludge removal in the Water Purification process. This is considered to be a
fair and reasonable price for the required work.
Background:
The WTP has two large DS-706 Alfa Laval centrifuges to process sludge at this facility. These
units are estimated at $1,000,000 each. They have been in service since the WTP began
operation in 1998, and occasionally require repair. Currently, the bearings have gone out and
some ceramic tiles are missing from the scroll of one of the units. There are no Port Arthur
vendors that provide this specialized service.
Budget Impact:
These are expensive and complex units that operate in the harshest of environments. As such,
they demand a very stringent preventive maintenance program, and are recommended for re-
build every 5-6 years. The above mentioned repair, in the amount of $51,450.00, has funds
available in account no. 410-1252-532.42-00 (Equipment Maintenance).

INTEROFFICE MEMORANDUM

Date: September 14, 2018
To: Harvey Robinson, Interim City Manager
From: Jeffrey, D. Wyble, Water Treatment Superintendent
RE: Emergency repair of dewatering centrifuge
Mr. Robinson,
We have two centrifuges that are critical to the water treatment process because they process the waste
material that is removed during treatment. Currently one unit is already being repaired and the other has
since gone down as well. It is imperative that we get this unit repaired because without the ability to
process waste, the treatment process gets backed up and it becomes harder and more costly to treat :he
