NIGP 21031: Drains, Parts and Accessories

NIGP 21031 Drains, Parts And Accessories is an Item code under which state and local governments procure drainage system components, catch basins, storm drainage pipe, inlets, reinforced concrete arch pipe, and related installation or replacement services for municipal infrastructure, parks, and roadway projects. Recent solicitations reflect active procurement across construction projects addressing flooding, stormwater management, and drainage system upgrades, with the issuing-body mix spanning county transportation and engineering divisions, municipal public works departments, park authorities, and transit jurisdictions. Greenville County, South Carolina issued IFB 27000 for the Merrifield Park Drainage Improvement Project (bids due July 24, 2026) seeking approximately 2,380 linear feet of storm drainage pipe ranging from 18 to 36 inches in diameter, aluminum arch pipe, and 24 catch basins and drop inlets; the City of Austin, Texas solicited through IFQ 6300 CAA1003 (quotations due June 1, 2026) for spot-purchase drainage system components including inlets, reinforced concrete arch pipe, and manholes with delivery within five business days of order. Clay County, Florida has been particularly active, issuing separate IFBs for drainage improvements at Carl Pugh Park (bids due April 27, 2026) and Oakleaf Community Park (bids due May 7, 2026), both addressing standing water and flooding through grading, stormwater pond construction, yard drains, and piping systems. The City of Santa Cruz, California solicited through IFB PW-0281 for Downtown Catch Basin Rehabilitation (bids due April 9, 2026) to replace undersized Type A catch basins and install trench drains with storm connections; a related procurement by the Texas Health and Human Services Commission on behalf of the Department of State Health Services included NIGP 210-31 as one of five codes in a roof repair IFB (responses due June 3, 2026) where drainage components were secondary to roofing work.

Geographic concentration appears heaviest in Florida and California, with Florida counties (Clay, Broward) showing repeat activity around park and municipal drainage upgrades, and California municipalities (Santa Cruz, Marietta adjacent in Georgia) conducting catch basin and stormwater system replacements. Texas activity includes the Austin spot-purchase contract and the state health facility roof repair with drainage components. South Carolina, Georgia, and Minnesota cooperative purchasing vehicles (Sourcewell) round out the geographic spread. Award criteria across these opportunities emphasize lowest responsive bid, with performance bonds and bid security in the five to ten percent range typical; mandatory pre-bid meetings are common, and project timelines range from 100 to 150 working days. The activity signals steady municipal and county infrastructure maintenance and improvement spending on drainage systems, particularly in response to flooding and stormwater management challenges in developed areas.
