BACKGROUND
The Orange County Sanitation District (OC San) owns approximately 4,400 manhole structures throughout Orange County that provide access to the wastewater collection system. Manhole structures are typically made of concrete and protectively lined with either an epoxy or PVC coating. As these assets age, the manhole structures require rehabilitation measures due to environmental corrosion, water infiltration, and age to extend their useful life. OC San currently contracts with a service provider to fulfill these needs.
RELEVANT STANDARDS
• Maintain a proactive asset management program
• Protect OC San assets
• Commitment to safety & reducing risk in all operations
PROBLEM
OC San manhole structures are typically made of concrete and protectively lined with either an epoxy or PVC coating. As these assets age, the manhole structures require rehabilitation since coating failures lead to corrosion which eventually compromise the structural integrity of the manhole. The current contracted service has reached the end of its approved renewal periods.
PROPOSED SOLUTION
Staff recommends approving a manhole rehabilitation services contract to Ayala Engineering, Inc.
TIMING CONCERNS
Once concrete or lining starts to fail on a manhole, the damage will spread if corrective action is not taken and, if left for long periods of time, can lead to a potential collapse. Additionally, it is important to react to and urgently repair manholes as lining material separating from the structure could fall into the sewer line causing a sewage spill.
RAMIFICATIONS OF NOT TAKING ACTION
Without a contract in place, degrading manhole structures will continue without mitigation and pose a structural risk to the wastewater collection system and the public. Individual purchase orders in lieu of a convenience blanket contracts are time-consuming and will reduce the speed at which repairs can commence.
