NIGP 658: Pipe, Tubing, and Accessories, Not Fittings

NIGP 658 Pipe, Tubing, and Accessories, Not Fittings is a Class code under which state and local governments procure corrugated aluminum pipe culverts, ductile iron pipe, polyethylene gas and water distribution pipe, PVC and CPVC chemical-resistant piping, HDPE irrigation pipe, and reinforced concrete drainage pipe for water infrastructure, wastewater systems, stormwater management, and utility distribution. Recent solicitations reflect active demand from water and sewer authorities, municipal public works departments, special water districts, and transit authorities across the South, Southwest, Northeast, and Mountain West for both commodity supply contracts and project-specific pipe installation and system rehabilitation work.

Recent activity spans water main replacement (City of Leesburg, Florida, IFB 26-015-LK, 3,500 linear feet of 12-inch C900 PVC pipe; City of Tampa, ITB 26-P-00565, 1,860 linear feet of 4-inch and 2,780 linear feet of 6-inch ductile iron pipe), wastewater and stormwater piping (City of South Jordan, Utah, IFB 2026030, UV-cured CIPP lining in existing corrugated metal pipe; Yardley Borough Sewer Authority, Pennsylvania, contract bids due July 1, 2026, approximately 5,725 linear feet across multiple gravity sewer sizes), chemical and industrial piping systems (Collier County, Florida, bid 26-8683R, 180 linear feet of 42-inch and 130 linear feet of 36-inch ductile iron pipe for a $4.27 million water treatment plant blend tank project; Madisonburg Water Works, Pennsylvania, 1,030 linear feet of 12-inch PVC pipe for chlorine contact systems), as-needed supply agreements (City of Phoenix Public Works, IFB 26-SW-0379 and IFB 27-SW-0447, HDPE and PVC pipe ranging 0.75 to 24 inches in diameter for three-year terms; Springfield Water and Sewer Commission, Massachusetts, IFB 27-08, ductile iron pipe on an as-needed basis, contract not to exceed $500,000 per year), and specialty applications including irrigation pipe (Dry Gulch Irrigation Company, Utah, approximately 14,300 linear feet of 12- and 16-inch HDPE DR 32.5 irrigation pipe across three schedules; Ashley Valley Water & Sewer Improvement District, Utah, 8-inch HDPE waterline bored under state highway). Geographic concentration appears strongest in Florida, Utah, Pennsylvania, Massachusetts, and Arizona, with additional solicitation activity in California, Delaware, Texas, and Connecticut. Award thresholds range from under $50,000 for single-commodity spot purchases to multi-million-dollar capital projects; three-year initial terms with one-year renewal options are common on supply contracts. Prevailing wage, E-Verify employment verification, and performance/payment bonding are routine compliance requirements on larger projects and wastewater work.
