UNSPSC 30181605: Drain

Plumbing fitting used as a conduit to remove water, or some other liquid, from somewhere that it is not wanted.

UNSPSC 30181605 Drain is a Commodity code. State and local governments use this code to solicit drainage system work ranging from stormwater and grease-trap services to complex site drainage construction and renovation. Recent solicitations show two dominant categories of work: grease-trap cleaning and maintenance services on indefinite-delivery contracts across municipalities, and site-level drainage construction and improvement projects managed through sealed-bid IFBs or RFPs. The City of Tupelo, Mississippi issued an IFB in October 2026 for industrial road drainage improvements including pipe installation and grading; the County of San Mateo issued an RFP in May 2026 for five-year sewer maintenance and grease-trap services with a fiscal obligation not to exceed $500,000; and the City of Albuquerque issued an RFB in May 2026 for grease-trap pumping and cleaning across 32 city and airport locations under a three-year Price Agreement with optional one-year renewal. School districts also appear under this code—San Antonio Independent School District posted multiple continuous, open-ended RFPs for general maintenance services including repairs and assessments, though the connection between the code's nominal scope and the district's broad maintenance buying is attenuated. Issuing bodies include city and county public works departments, water authorities, independent school districts, and state environmental services agencies.

Recent activity clusters in Texas (San Antonio ISD, Harris County, City of Dallas, City of Albuquerque), California (County of San Mateo), Florida (Clay County, City of St. Marys, Clayton County Water Authority), Mississippi (City of Tupelo), Georgia (City of St. Marys), and Maryland (Maryland Environmental Service). The City of Dallas solicited a 60-month ID/IQ service agreement for sand trap, grease trap, septic tank, storm vault, and interceptor cleaning with bids due August 2026. Clay County, Florida posted two separate IFBs for park drainage improvements—Carl Pugh Park in April 2026 (due April 27) and Oakleaf Community Park in April 2026 (due May 7)—both addressing stormwater systems and standing-water elimination. The City of Albuquerque's RFB allowed vendor preferences up to 10 percent combined for small business, local business, state resident, pay equity, and state resident veteran certification. Minimum qualifications across drainage service solicitations typically require active contractor licenses, relevant experience within the prior five to seven years, insurance thresholds of $1 million per occurrence or higher, and for airport or secure-facility work, badge and vetting compliance.
