BACKGROUND
The Orange County Sanitation District (OC San) operates 15 pump stations within its regional collection system. These pump stations lift wastewater from low points where a gravity flow system cannot be used and are considered critical infrastructure to convey wastewater to the treatment plants. The pumps require routine removal and restoration activities to maintain design capacity output due to normal wear and tear. These pump stations are critical to the operation of the collection system and may result in a backup or sewer spill if pumping capacity is lost.
RELEVANT STANDARDS
• Achieve less than 2.1 sewer spills per 100 miles
• Commitment to safety & reducing risk in all operations
• Protect OC San assets
PROBLEM
The main lift pumps at Bitter Point Pump Station require removal for overhauls. However, without spare replacements on hand, this overhaul process leads to a temporary loss of pumping capacity. Additionally, the extended lead times in modern supply chains for required overhaul services reduce system redundancy, increasing the risk of service disruptions.
PROPOSED SOLUTION
Approve the Sole Source Purchase Order of a spare rotating assembly pump from Flo-Systems, Inc. for the Bitter Point Pump Station to maintain asset availability and minimize operational downtime.
TIMING CONCERNS
The spare rotating assembly pump identified for purchase has a lead time of up to 25 weeks, or longer, depending on availability.
RAMIFICATIONS OF NOT TAKING ACTION
Losing pump station pumping capacity due to the long lead times increases the risk of a sewer spill.
PRIOR COMMITTEE/BOARD ACTIONS
February 2021 - Board Approved Hidrostal, LLC. to the pre-approved OEM Sole Source List for the period of October 1 ,2020 to December 31, 2020, for pumps and replacement parts.
ADDITIONAL INFORMATION
Flo-Systems, Inc. is the Board-approved Original Equipment Manufacturer (OEM) authorized sales representative for Wemco/Hidrostal, LLC in OC San’s region.
