NIGP 93664: Purification and Filtering Devices Maintenance and Repair

NIGP 93664 Purification and Filtering Devices Maintenance and Repair, an Item code, covers comprehensive maintenance, repair, inspection, testing, and parts supply for water treatment and filtration equipment serving municipal and institutional water systems. State and local governments soliciting under this code purchase routine and emergency service for clarifiers, reverse osmosis and deionization systems, non-potable water filters, drinking fountain and ice machine filters, and associated instrumentation calibration and certification. The issuing bodies span city water and wastewater departments, county school districts, state health agencies, and municipal consolidated governments. Recent solicitations show water utilities and public health laboratories as the primary buyers, with school districts also active in filter replacement services at scale.

Activity concentrates in Texas, Florida, Georgia, and North Carolina, with the Texas Health and Human Services Commission soliciting twice for laboratory RO/DI system maintenance and bottle exchange services due July 2 and July 16, 2026; Hillsborough County Public Schools in Florida seeking bids through ITB 26233-ITB-MST for drinking fountain and ice machine filter services across 235 schools and district offices, covering approximately 6,500 water coolers and 460 ice machines with bids originally due August 5, 2026, extended to August 12, 2026 by addendum; the City of Houston issuing IFB BVB20260002 for clarifier maintenance and repair services with bids due November 19, 2026; the City of Charlotte, North Carolina soliciting through ITB FY26-ITB-10 for a complete pressurized strainer-type filter system design and manufacture for the Mallard Creek Water Resource Recovery Facility, with bids due May 27, 2026; the City of Tucson seeking an advanced water purification facility operator through a two-step RFP with Step 1 proposals due June 4, 2026; and the City of Tampa announcing intent to single source Sulzer/ABS pump products and authorized repair services. Pricing structures vary—some solicitations specify unit rates and labor-hour schedules, while others use lump-sum fixed pricing or monthly service fees. Insurance requirements typically include $1 million general liability and professional liability minimums, and most vendors must demonstrate minimum three to five years' documented experience with similar commercial or industrial systems and provide verifiable references.
