body
BACKGROUND
Orange County Sanitation District (OC San) owns and operates four Combination Sewer Cleaning trucks within its fleet. The trucks maintain the collection systems by cleaning sewer pipes and pump station wet wells, and by responding to emergencies such as sewer spills, using a combination of vacuum and water-jetting technology.
The Combination Sewer Cleaning trucks consist of specialized cleaning equipment with controls, hydraulic systems, and a large tank debris body mounted on a chassis. These trucks service more than 380 miles of regional pipes and 15 outlying pump stations, three reliable units are required to complete the annual volume of work and comply with the Sewer System Management Plan (SSMP) as required by the State Water Resources Control Board (SWRCB).
RELEVANT STANDARDS
• Participate in local, state, and national cooperative purchasing programs
• Maintain a proactive asset management program
• Ensure the public’s money is wisely spent
PROBLEM
The truck identified for refurbishment is experiencing increasing electrical, mechanical, and hydraulic failures due to age and corrosion. Continued repairs are becoming less effective and cost-efficient, making refurbishment or replacement the only viable long-term options.
PROPOSED SOLUTION
Refurbish the truck through the Original Equipment Manufacturer (OEM)-authorized service representative to restore the equipment to near-new condition, improve reliability, and maximize its remaining useful life at a lower cost than replacement.
TIMING CONCERNS
Delaying the refurbishment would increase the risk of equipment downtime and reduce OC San’s ability to maintain adequate fleet availability of Combination Sewer Cleaning trucks to support scheduled cleaning, emergency response and regulatory compliance activities.
RAMIFICATIONS OF NOT TAKING ACTION
Continued deterioration of the truck could result in extended downtime, increased reliance on rental equipment, higher maintenance costs, and reduced fleet availability. This could impair OC San’s ability to perform scheduled cleaning activities and respond effectively to collection system emergencies.
PRIOR COMMITTEE/BOARD ACTIONS
August 2017 - Approved Vactor as an Original Equipment Manufacturer (OEM) Sole Source for industrial cleaning truck rental and repairs.
ADDITIONAL INFORMATION
OC San’s Board of Directors approved Vactor as the OEM sole source provider under Board M.O. 9(B) on August 23, 2017. Haaker Equipment Company is Vactor’s sole authorized dealer for Vactor in Southern California. By using the OEM-authorized dealer and OEM parts, OC San received a discount of $37,730.
The truck profiled for refurbishment is seven years old and has a reliably operating chassis. The installed equipment on the chassis will be restored to near-new condition, allowing OC San to operate the unit well into its profiled 15-year life cycle. Refurbishment is significantly less costly than replacing the vehicle and allows OC San to extend the useful life of an existing asset with a serviceable chassis.
With newly adopted and imposed regulations (CARB Advanced Clean Fleets) affecting heavy-duty vehicles, the unit would need to be replaced as an alternative-fueled/electric vehicle at a substantially higher cost in a market with supply chain delays. Keeping this unit in OC San’s fleet ensures the reliability of critical equipment for maintaining the collection system.
A 15% contingency is recommended to address any additional repairs or replacement components identified during the refurbishment process.
