NIGP 91378: Maintenance and Repair, Pipeline (Includes Removal and Relocation)

NIGP Item 91378, Maintenance and Repair, Pipeline (Includes Removal and Relocation), encompasses water and wastewater infrastructure work that state and local governments solicit on an ongoing basis—specifically the installation, replacement, repair, and relocation of pressurized water mains, gravity sewer lines, force mains, irrigation systems, and associated appurtenances such as valves, hydrants, meter vaults, and lift station modifications. Recent solicitations show municipalities and utilities contracting for water main replacements (plastic-to-copper conversions, asbestos-cement-to-PVC upgrades, ductile iron installations), sewer line repairs and extensions, stormwater piping work, and emergency utility relocations driven by highway and bridge projects. Work under this code spans routine maintenance contracts, fixed-price project delivery, unit-price standing agreements, and design-build engagements that combine engineering with construction.

Issuing bodies include city water departments and utilities (DeBary, Casselberry, Sandersville, Commerce, Dallas, Midland, Atlanta, Baker, DeKalb County Water Authority, Cobb County-Marietta Water Authority, Gwinnett County, and Forsyth County), county departments of transportation and watershed management (Fulton County, Collier County), regional water and sewerage authorities (Cherokee County, Byromville), and special-purpose districts. Recent opportunities posted by the City of Midland, Gwinnett County, Forsyth County, Cobb County-Marietta Water Authority, and multiple Florida municipalities signal repeat procurement activity. Geographic concentration appears heaviest in Georgia, Florida, and Texas, with activity also evident in California, South Carolina, Connecticut, and Oregon. Representative recent solicitations include the City of Casselberry's $9.36 million Eastbrook Water Main Replacement Phase I (ITB, response date August 6, 2026 [superseded]), the Town of Waterford Utility Commission's replacement of plastic water services with copper on Rope Ferry Road (IFB #26-014, response November 12, 2026), the Medford Irrigation District's irrigation facility relocation coordinated with Oregon DOT under federal Buy America compliance (RFP, response November 9, 2026), and Gwinnett County's State Route 120 Water Main Replacement project requiring prequalification in the 16-inch-to-24-inch installation category (pre-qualified bidders only, response September 4, 2026). Paulding County's stormwater infrastructure unit-price indefinite-quantity contract (response November 6, 2026) and DeKalb County's three-year valve and wet tap installation services contract (ITB response August 19, 2026) illustrate the standing-agreement and recurring-services model within the code.
