NIGP 91359: Construction and Upgrades, Wastewater Treatment Plant

NIGP 91359 Construction and Upgrades, Wastewater Treatment Plant, an Item code, encompasses design, construction, rehabilitation, and upgrade work on wastewater and water reclamation facilities—including treatment plant infrastructure, pump stations, force mains, clarifiers, digesters, filter systems, and associated mechanical, electrical, and control systems. State and local governments are actively procuring under this code to address aging infrastructure, regulatory compliance (particularly PFAS treatment requirements), operational efficiency improvements, and emergency repairs across facilities ranging from small municipal plants to large regional water reclamation centers.

Issuing bodies span state environmental and transportation departments, county water authorities and utilities, cities and municipalities, special-purpose water and sewer districts, and regional water management entities. Repeat buyers include the Great Lakes Water Authority (Michigan), Gwinnett County (Georgia), Cobb County (Georgia), City of Houston (Texas), Chatham County (Georgia), Fulton County (Georgia), Orange County (Florida), Dallas Water Utilities (Texas), and DeKalb County (Georgia). Recent opportunities show a mix of design-build and construction-manager-at-risk delivery methods alongside traditional IFB and RFP formats. Geographic activity concentrates in Florida, Georgia, Texas, and the Southwest, with secondary clusters in the Pacific Northwest, Michigan, Ohio, and Massachusetts. Representative recent opportunities include the Great Lakes Water Authority's 2027 Job Order Contract (RFP, due August 27, 2026) for multi-project wastewater management across Michigan; Cobb County's secondary clarifier rehabilitation at the South Cobb Water Reclamation Facility (IFB, due August 27, 2026); the City of Houston's Clinton Park and Upper Brays wastewater treatment plant improvements (IFB, dues August 20 and July 30, 2026, estimated at $13.775 million); Fulton County's Friendship Pump Station progressive design-build (RFP, due August 12, 2026 with a 5% local-preference weighting); Orange County's $14.3 million SCADA and PLC replacement project at the East Water Reclamation Facility (IFB, due July 28, 2026); and Broward County's $375 million PFAS water treatment and transmission system improvements (RFP for Managing General Contractor, due May 28, 2026). Liquidated damages, prevailing wage, bonding, and insurance requirements are standard; MBE and WBE participation goals appear in Houston and Dallas solicitations, while local-business and local-preference provisions apply in Fulton County, Philadelphia, and Collier County. The code is active with near-term deadlines and substantial dollar volumes across the region.
