NIGP 21035: Joint Sealing Compound (for Sewer and Drain Pipes)

NIGP 21035 Joint Sealing Compound (For Sewer And Drain Pipes) is an Item code that captures products and services used to seal, repair, and maintain underground sewer and drain infrastructure. State and local governments procure under this code primarily as part of larger infrastructure projects involving sewer line rehabilitation, force main replacement, and emergency sewer repairs—work that often includes point repairs to existing lines, cured-in-place pipe (CIPP) lining operations, and lateral connection work. The issuing bodies span municipalities (Detroit, Orlando, Atlanta, Olathe, Brownsville, Marietta, Sylvester), counties (Orange County Florida, Pinellas County Florida, Broward County Florida, Santa Clara County California), and special-purpose water and sewer districts. Cities in Florida and Georgia dominate recent activity, with Detroit, Michigan and Kansas municipalities also active. Scope work includes sewer rehabilitation via CIPP installation, sanitary sewer force main replacement (ranging from 216 to 7,520 linear feet of pipe), alley sewer service line replacement, point repairs to public sewers, and lateral liner installation—all delivery-critical infrastructure with strict completion timelines and liquidated damages for delays.

Representative recent opportunities include the City of Detroit's CDBG-DR Alley Sewer Repair Project (RFQ 546919, due July 21, 2026), an as-needed contract for inspection, rehabilitation, and replacement of approximately 360 alley sewer locations citywide with 50 percent Detroit resident and 25 percent minority workforce requirements; and the City of Olathe's Arrowhead Truss Mains Sanitary Sewer Rehabilitation (ITB, due March 26, 2026), covering 7,520 linear feet of 8-inch CIPP liner installation with 150-day substantial completion and $500 per-day liquidated damages. Orange County, Florida issued a five-year Sewer Pipes and Fittings contract (Y26-126, due January 22, 2026) with an estimated $28.7 million spend across 56 line items of PVC and ductile iron pipe, fittings, and valves, structured as percentage discounts from MSRP with 8 percent Service Disabled Veteran Business preference. The code sees steady activity across municipal water and sewer departments managing aging infrastructure, with high compliance requirements (Davis-Bacon wage rates, living wage minimums, E-Verify), performance bonding at 100 to 210 percent of contract value, and project timelines typically spanning 120 to 730 days with substantial-completion milestones.
