NIGP 92596: Waste Water Treatment Engineering

NIGP 92596 Waste Water Treatment Engineering is an Item code under which state and local governments procure equipment, chemicals, professional services, and construction support for wastewater treatment facility operations, rehabilitation, and expansion. Recent solicitations reflect a mix of equipment purchases (turbo blowers, grinder systems, ash handling components), chemical supplies for treatment processes, design and construction management services for facility improvements, and specialized engineering for capacity expansion and regulatory compliance.

Issuing bodies across the code include municipal water and wastewater utilities, county utilities departments, and regional authorities in Florida, Georgia, Ohio, Oregon, Arizona, California, and Colorado. The City of Bend (Oregon) issued two solicitations in October 2026 for a turbo blower installation (RFP due November 18) and Southwest Sewer Improvements Phase 3 (RFP due September 30, $3.875 million total project budget). Collier County, Florida solicited countywide treatment chemicals across 29 line items (ITB due November 13) with historical county spending around $4 million annually. Wayne County, Michigan (RFP due November 24) and Atlanta's Department of Watershed Management (prequalification due October 30 for the Peachtree Raw Water Pump Station progressive design-build) represent larger infrastructure rehabilitation work. Phoenix solicited construction administration and inspection services for redundant force main work ($7.9 million estimated construction cost, qualifications due October 30) and sewer pipe rehabilitation engineering (qualifications due September 18). The City of Waco issued an RFQ for Flat Creek Reuse Project Phase 1A design and construction oversight (due December 1, federally funded, requiring DBE participation and Davis-Bacon compliance). Design-build and progressive design-build delivery appears across multiple recent opportunities in Ohio, Georgia, Florida, and Arizona, reflecting increased preference for integrated project delivery in water infrastructure modernization. Geographic activity concentrates in Florida (Collier, Brevard, Seminole, Pinellas, Hillsborough, Plant City, Sanford, Winter Park counties and municipalities), Georgia (Atlanta, Cobb County, Rome, Demorest, Griffin, McRae-Helena), and Arizona (Tucson, Phoenix), with secondary activity in Oregon, Ohio, Colorado, Michigan, and California. Federal compliance triggers—Davis-Bacon, Build America Buy America, DBE participation, 2 CFR 200 procurement standards—appear consistently in design and construction procurements, particularly those funded through CDBG, GEFA, FEMA, or state revolving funds.
