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

NIGP 21035 Joint Sealing Compound (For Sewer And Drain Pipes), an Item code, addresses infrastructure repair and maintenance across water and sewer systems where state and local governments solicit specialized materials and services for pipeline rehabilitation, cleaning, and structural repair. Recent solicitations show that jurisdictions are procuring drainage infrastructure work—including pipe replacement, lining, relining, and cleaning services—rather than discrete sealing compound purchases, suggesting that the code captures the broader ecosystem of sewer and drain system rehabilitation where joint sealants form part of integrated construction scope. Cities, counties, and special-purpose districts issue the bulk of solicitations under this code, with repeat activity from major urban centers including Detroit, Orlando, and Santa Clara County.

Recent opportunities span Florida, Michigan, Connecticut, California, Georgia, Texas, and Oregon, with particularly active procurement from the City of Orlando (multiple water reclamation facility projects), Santa Clara County Sanitation District, and Detroit's Housing and Revitalization Department. Representative solicitations include the City of Leesburg, Florida IFB 26015LK for Bentley Road 12-inch main replacement (bids due June 18, 2026, engineer's estimate $975,980.40); the City of Meriden, Connecticut RFP027-21 for comprehensive sewer main and manhole lining and re-lining services (proposals due October 1, 2026, requiring contractors with experience lining over 3,000,000 linear feet of pipe including 250,000 feet of 24-inch or larger diameter); and Sanitation District No. 2-3 in Santa Clara County ITB RDA FY 270088 for structural defect repair including point repairs, pipe-burst replacements, and mainline extensions (bids due September 17, 2026). The City of Detroit Office of Contracting and Procurement has issued multiple RFQs including drain cleaning services (550935, due October 2, 2026) and alley sewer repair on an as-needed basis (546919, due July 21, 2026, CDBG-DR funded with prevailing wage and Detroit resident–workforce requirements). These opportunities signal sustained capital investment in aging sewer infrastructure and compliance-driven rehabilitation programs, particularly in mid-sized to large municipalities managing combined and sanitary sewer systems.
