NIGP 93664: Purification and Filtering Devices Maintenance and Repair

NIGP Item 93664 Purification and Filtering Devices Maintenance and Repair covers preventative maintenance, emergency repair, parts replacement, and specialized servicing for water treatment systems including reverse osmosis, deionization, ozone, and pressurized strainer filtration equipment used in municipal water supply, wastewater reclamation, laboratory, and aquaculture applications. State and local buyers under this code procure routine servicing (monthly, quarterly, annual visits), emergency response capability (same-day to 48-hour turnaround), component replacement (filters, UV lamps, resin beds, membranes), system sanitization, and operator training for purification infrastructure. Recent solicitations show Texas Health and Human Services Commission (HHSC) and water departments in Texas, North Carolina, and Arizona as repeat buyers, alongside single-source repair agreements (City of Tampa for pump products) and equipment procurement for new treatment capacity (Charlotte Water for filter systems, Tucson Water Department for advanced purification operations).

Activity is concentrated in Texas and the Southeast, with recent opportunities posted from April through July 2026. The Texas Health and Human Services Commission issued two IFBs in June and July 2026 for preventative maintenance and bottle-exchange services on RO/DI systems at its Austin laboratory (HHS0017246, due July 2, 2026; HHS0017251, due July 16, 2026), both requiring five years' documented experience, $1 million general liability and professional liability coverage, and firm fixed pricing for 12-month initial terms with three one-year renewal options. Charlotte Water solicited design and delivery of a pressurized strainer-filter system for its Mallard Creek Water Resource Recovery Facility (ITB FY26-ITB-10, due May 27, 2026), with M/W/SBE utilization requirements and three-reference documentation. The City of Dallas issued a 36-month ID/IQ ozone system maintenance agreement covering three water treatment plants (BH2600029988, due May 15, 2026), requiring five years' ozone maintenance experience and SBE participation goals under its DRIVE policy. The City of Tucson Water Department sought an operator for its Advanced Water Purification Facility through a two-step RFP (260227, Step 1 due June 4, 2026), encompassing 15-year operations and maintenance with design-phase input responsibilities and 15-year compliance with HUD Section 3 employment requirements.
