MEMORANDUM
TO:
Honorable Mayor and Members of the Common Council
FROM:
Stephan M. Brand, Public Works Utility Bureau ManagerQ J -1u7
DATE: June 29, 2018
RE: Approve Agreement with Centrisys for Repair of Wastewater Treatment Plant Centrifuge ($45,000)
BACKGROUND
The Wastewater Treatment Plant (WWTP) utilizes two (2) Alfa Laval centrifuges for the dewatering of biosolids as part of
the wastewater treatment process. These centrifuges were originally installed in 1996 and have been maintained and
upgraded, as needed. The biosolids generated are beneficially re -used through the application to agricultural fields in strict
compliance with Wisconsin Department of Natural Resources requirements. The conical section replacement for Centrifuge
No. 1, approved for purchase from Alfa Laval by the Common Council in October 2017, has been received and needs to be
installed. Centrisys specializes in the repair and maintenance of centrifuges, and is the only regionally -located firm with
the capability and qualifications to perform the appropriate repairs to this equipment. A similar replacement was
performed by Centrisys on Centrifuge No. 2 in 2016.
ANALYSIS
The WWTP's dewatering centrifuges are very specialized equipment. This work needs to be performed by a company that
has experience with this type of equipment. Centrysys has performed this work for the WWTP in the past and has done an
excellent job at providing this service in an efficient and cost-effective manner.
FISCAL IMPACT
Funding is available in the Wastewater Utility Major Equipment Replacement section of the 2017 Capital Improvement
Program.
RECOMMENDATIONS
Chapter 12 of the Municipal Code of the City of Oshkosh provides that services of a specialized nature, including purchases,
may be made without a formal competitive bidding process when the purchase is from only one source of supply or when
standardization or compatibility is the overriding consideration. I have reviewed the proposal and, in accordance with
Section 12-11 of the Code, I am hereby recommending the Common Council approve this purchase.
Approved,
Mark A. �Rohlo:��
