NIGP 65846: Pipe, Iron (Includes Ductile Iron Pipe)

NIGP 65846 Pipe, Iron (Includes Ductile Iron Pipe) is an Item code covering supply of ductile iron and related iron pipe products that state and local water utilities, public works departments, and wastewater authorities procure for water main, force main, and transmission line projects. Recent solicitations show active demand for both commodity supply contracts and project-specific materials: the City of Phoenix is establishing a three-year as-needed IFB for industrial pipe and fittings (response due August 12, 2026); the City of Dallas is seeking a five-year ID/IQ master agreement for ductile iron pipe supply to its Water Utilities department (deadline June 12, 2026); and DeKalb County, Georgia is requesting bids on ductile iron water pipe under a three-year multiyear contract (due July 2, 2026). Municipal water authorities also solicit under this code for discrete construction projects—the City of Sarasota sought materials-only bids for potable water pipe and fittings conforming to its approved manufacturers list; the Beaufort-Jasper Water & Sewer Authority in South Carolina issued an IFB for 16-inch steel water transmission main replacement involving approximately 12,200 linear feet of pipe; and the Cherokee County Water and Sewerage Authority in Georgia solicited bids for water main relocation work specifying 9,100 linear feet of 20-inch DIP water main, 2,000 linear feet of 12-inch DIP, and 13,000 linear feet of 8-inch DIP.

Issuing bodies are predominantly municipal water utilities, county water authorities, and city public works departments across the southeastern United States, with significant recent activity in Florida, Georgia, and the Southwest. The City of Madison, Wisconsin issued RFQs for both ductile iron pipe and tapping sleeves (due March 17, 2026), and the Town of Berlin, Connecticut solicited construction services for water main interconnection requiring approximately 2,300 linear feet of 12-inch ductile iron water main (response due April 15, 2026). Geographic concentration spans Florida (Orange County, City of Palm Bay, City of Sarasota, Pinellas County), Georgia (DeKalb County, Gwinnett County, Bryan County, Cherokee County, Franklin County, City of Calhoun, City of Lavonia), and broader coverage in Texas (City of Dallas, City of Frisco), Connecticut, Wisconsin, South Carolina, and Illinois. The code sees steady activity across both standing supply agreements—typically three to five years with as-needed ordering and 24–48-hour delivery expectations—and construction-phase material procurement tied to specific infrastructure projects. Buy America and BABA Act compliance is frequently required where federal or state revolving fund financing applies; DBE, SBE, and MBE participation goals appear in multiple recent solicitations, particularly those receiving federal infrastructure funding.
