UNSPSC 40142515: S trap

S shaped piece of pipe that is located below or within a plumbing fixture that holds a small amount of water to prevent sewer gas from entering a building.

UNSPSC 40142515 S trap, a Commodity code, covers plumbing fixtures and drainage components that state and local governments procure primarily as part of larger construction, renovation, and maintenance projects rather than as standalone items. Recent solicitations show the code applied inconsistently across work that ranges from grease trap cleaning services to bathroom renovations and stormwater drainage improvements—indicating either broad tagging at the project level or vendor interpretation that does not align precisely with the fixture-specific code name. The actual procurement activity centers on grease trap and septic system maintenance (pumping, cleaning, disposal), bathroom and restroom renovations that include trap installation or replacement, and drainage system construction where S traps and similar fixtures form part of broader piping infrastructure. Issuing bodies include city public works departments, county facilities and water authorities, and special-purpose districts; cities of Albuquerque, Dallas, and Tupelo, along with San Mateo County and Clayton County Water Authority, appear in recent postings.

Geographic activity concentrates in the Southwest and South, with Texas (Dallas, Harris County), New Mexico (Albuquerque), California (San Mateo County), Georgia (St. Marys), Mississippi (Tupelo), and Florida (Clay County) showing recent solicitations. Representative recent opportunities include the City of Dallas's 60-month ID/IQ for sand traps, grease traps, septic tanks, storm vaults, and interceptor cleaning and disposal services (bids due August 14, 2026); the City of Albuquerque's grease trap pumping and cleaning services across 32 city and airport locations under RFB-2026-777-VAR-GS (proposals due June 22, 2026), which offers up to 10% combined vendor preferences including small business, local business, and state resident certifications; San Mateo County Department of Public Works's five-year RFP for combined sewer maintenance, repair, and grease trap services with an aggregate fiscal obligation not to exceed $500,000 (deadline May 20, 2026); and Clay County's drainage improvement projects at Carl Pugh Park and Oakleaf Community Park, both involving stormwater piping and yard drain installation (bids due April 27 and May 7, 2026, respectively).
