UNSPSC 40174611: HDPE plastic pipe tee

Pipe tee made of HDPE plastic

UNSPSC 40174611 HDPE plastic pipe tee, a Commodity code, covers plastic drainage and water conveyance fittings that state and local governments procure for sewer, water main, and stormwater infrastructure projects. Solicitations under this code reflect purchase of HDPE tees as components within larger rehabilitation and replacement projects involving gravity sewer mainlines, potable water distribution systems, and storm collection networks. Issuing bodies include county sanitation districts, county public works departments, and municipal utilities. The code shows activity across counties and special districts rather than school districts or transit authorities; Santa Clara County's Sanitation District No. 2-3 and Pinellas County, Florida emerge as recent repeat buyers of water and sewer infrastructure construction services that bundle HDPE piping components into sealed-bid procurements.

Recent activity concentrates in California and Florida. Sanitation District No. 2-3 in Santa Clara County posted ITB ITBRDAFY270088 for the Structural Defect Repair Project Phase 2 with bids due September 17, 2026, which specified 1,080 linear feet of 6-inch HDPE pipe for pipe-burst replacement within a sanitary sewer rehabilitation scope; the District also manages concurrent pavement work under ITB ITBRDAFY260694 (Central Expressway Pavement Rehabilitation, bids due May 21, 2026). Pinellas County, Florida released ITB 260652ITBC for the Ridgewood Estates Sewer Improvements and 82nd Avenue & 113th Street Water Main Improvements with a minimum qualification submittal due October 13, 2026 and final bids due November 5, 2026; the sewer scope includes approximately 500 linear feet of 12-inch PVC sanitary sewer pipe and related appurtenances, while the water main scope involves replacement of approximately 6,800 linear feet of 6-inch water main with a 10% SBE participation goal. Neither opportunity explicitly listed HDPE tees as a line item, but both projects occur in utility infrastructure corridors where tee fittings are standard components of gravity sewer and pressure water systems.
