GENERAL MANAGER'S RECOMMENDATION
recommendation
RECOMMENDATION:
A. Approve a Sole Source Purchase Order to GEA Mechanical Equipment US Inc. for the purchase of inventory spare parts for Thickening and Dewatering centrifuges, for a total amount not to exceed $103,913, plus applicable sales tax and freight; and
B. Approve a contingency of $10,392 (10%).
body
BACKGROUND
As part of Project No. P1-101, three GEA-Westfalia Separator Thickening Centrifuges and three GEA-Westfalia Dewatering Centrifuges were commissioned. Thickening centrifuges thicken the sludge feed for the digestion process to increase solids density. dewatering centrifuges remove water from biosolids to make the material suitable for truck transportation. The sludge thickening and the biosolids dewatering processes are central to the biosolids recycling program and complying with the Orange County Sanitation District's (Sanitation District) operating permits.
RELEVANT STANDARDS
* 24/7/365 treatment plant reliability
* Maintain a proactive asset management program
* Operate and maintain facilities to minimize impacts on surrounding communities, including odor, noise, and lighting
PROBLEM
The Sanitation District has identified critical Original Equipment Manufacturer (OEM) spare parts that are not in inventory that are subject to normal wear. These OEM spare parts are not "off the shelf," nor readily available, and have long lead times that compromise equipment availability.
PROPOSED SOLUTION
Procure spare inventory parts for GEA centrifuges from the OEM to maintain asset availability and minimize process downtime.
TIMING CONCERNS
N/A
RAMIFICATIONS OF NOT TAKING ACTION
Failure to maintain adequate spare parts in inventory could result in extended equipment downtime affecting operational permits.
