UNSPSC 40174903: Cast iron pipe union

Pipe union made of cast iron

UNSPSC 40174903 Cast iron pipe union (Commodity) addresses components for sanitary sewer rehabilitation and replacement work, though recent state and local solicitations show that jurisdictions are buying cast iron pipe unions as part of broader sewer infrastructure repair and pavement projects rather than as standalone inventory items. The work involves removal and replacement of existing deteriorated sewer pipe—including cast iron segments—with modern alternatives such as PVC, HDPE, and related fittings and connections. State and local buyers soliciting under this code include county sanitation districts and county public works departments conducting mainline sewer repairs, service connection replacements, and sewer system extensions.

Santa Clara County issued the two most recent solicitations, both as ITBs with physical bid submission. County Sanitation District No. 2-3 posted ITB ITBRDAFY270088 on August 26, 2026 (due September 17, 2026) for the Structural Defect Repair Project Phase 2, encompassing thirty-five sanitary sewer mainline point repairs, five mainline pipe-burst replacements, and two sewer mainline extensions in the unincorporated eastern foothills, with work including removal and replacement of 1,080 linear feet of existing 6-inch cast iron pipe via bursting and conversion to HDPE, plus service connection fittings including wyes at multiple diameters. Santa Clara County Department of Roads and Airports posted ITB ITBRDAFY260694 on April 29, 2026 (due May 21, 2026) for the Central Expressway Pavement Rehabilitation Project, a broader infrastructure project that includes pavement work and related improvements but does not detail cast iron pipe specifications in the available summary. Recent activity centers on Santa Clara County in California, with focus on sewer rehabilitation and system modernization projects requiring sixty-five to 142 working days for completion.
