NIGP 91468: Plumbing

NIGP 91468 Plumbing, an Item code, encompasses installation, repair, maintenance, and replacement of water supply, drainage, and gas piping systems across municipal and institutional facilities. State and local governments procure plumbing services through both time-and-materials on-call arrangements and fixed-price project-specific contracts covering everything from routine fixture replacement to comprehensive system upgrades, water line extensions, sewer infrastructure work, and specialized tasks such as backflow prevention testing and fire hydrant servicing. Issuing bodies span county commissioners' offices, city public works and utilities departments, independent school districts, community colleges, state agencies, state-supported living centers, and transportation authorities. Recent activity shows county governments and municipal utilities departments as particularly active buyers, with school districts and state facilities management divisions also regularly soliciting plumbing services.

Recent procurement spreads across multiple states with notable concentration in Texas, California, Florida, Michigan, Washington, and Georgia.
