NIGP 75508: Ash System Equipment, Fly and Bottom

NIGP Item 75508 Ash System Equipment, Fly And Bottom encompasses equipment and rehabilitation services for ash handling infrastructure at municipal water and wastewater treatment facilities. State and local governments procure replacement components, system upgrades, and comprehensive rehabilitation of fly ash and bottom ash handling systems — the mechanical and structural equipment that collects, transports, and manages combustion byproducts from treatment processes. Issuing bodies include county water authorities and regional treatment-facility operators responsible for maintaining operational continuity of resource recovery infrastructure.

Wayne County, Michigan solicited bids for rehabilitation of the ash handling system at its Water Resource Recovery Facility in October 2026, with proposals due November 24, 2026. The recent opportunity activity reflects procurement concentrated in the upper Midwest and West Coast regions, though the source provides limited geographic breadth to characterize broader state-level patterns. Vendors pursuing this code should expect episodic, facility-specific infrastructure projects rather than steady-state commodity purchasing, and should maintain capability in both equipment supply and system integration services to compete effectively when opportunities arise.
