NIGP 96759: Plastics and Plastic Products (incl. Fiberglass, Poly, etc.)

NIGP 96759 Plastics and Plastic Products (including fiberglass and polyethylene), an Item code, encompasses high-density polyethylene (HDPE) slip linings, spiral wound liners, and cured-in-place pipe (CIPP) materials used in trenchless wastewater infrastructure rehabilitation and replacement projects. State and local water utilities and public works departments procure these plastic pipe products and systems to rehabilitate aging gravity wastewater collection systems without extensive excavation, particularly where existing reinforced concrete pipe requires structural restoration or replacement in environmentally sensitive areas, high-traffic corridors, or areas subject to regulatory constraints. The scope includes the materials, installation systems, and associated plastic components required for pipeline renewal in municipal water and wastewater districts.

Dallas County Water Utilities (DWU) issued a Request for Competitive Sealed Proposals (CIZDWU26040) with a June 5, 2026 response date for the trenchless rehabilitation of approximately 5,150 linear feet of a 1950s-era 60-inch reinforced concrete pipe gravity wastewater system in South Dallas, incorporating approximately 4,790 linear feet of Machine Spiral Wound Liner (MSWL) technology and approximately 360 linear feet of CIPP followed by HDPE slip lining for the Trinity River crossing section. The project reflects the active market for plastic pipe rehabilitation materials in municipal infrastructure renewal, with specifications emphasizing coordination across FEMA Regulatory Floodway, United States Army Corps of Engineers Lamar Levee Extension Project Area, and multiple rights-of-way including Oncor High Voltage Transmission corridors, active Union Pacific Railroad, and Texas Department of Transportation corridors. The procurement includes SBE set-aside designations and local participation requirements, with submission deadline for final specifications and bid documents set for May 8, 2026, and bid due date of June 5, 2026.
