NIGP 21075: Septic Tanks, Grease Traps, and Water Troughs

NIGP 21075 Septic Tanks, Grease Traps, and Water Troughs is an Item code representing intake, treatment, and disposal services for grease trap waste, domestic septic waste, biosolids, and related wastewater byproducts at state and local facilities. State and local governments purchase pumping, cleaning, maintenance, inspection, and compliant disposal of grease traps, septic tanks, and interceptor systems across municipal facilities, county maintenance yards, airports, schools, senior centers, correctional facilities, and water treatment plants. Recent solicitations show active procurement across school districts, county departments, cities, and special-purpose districts, with issuing bodies including the School Board of Volusia County (Florida), Fulton County (Georgia), Santa Clara County (California), the City of Albuquerque, Broward County (Florida), Dallas Independent School District, Hartsfield-Jackson Atlanta International Airport (City of Atlanta), and the County of San Mateo. Work ranges from routine grease trap pumping and interior cleaning to septic system abandonment, lift station maintenance, and emergency response services. Scopes typically require contractors to hold relevant state licensing—such as C-36 Plumbing Contractor's License in California or Commercial Septic Tank licenses in Georgia—and compliance with EPA, state environmental protection agency rules, and local grease management ordinances. Insurance requirements commonly include general liability, pollution liability, and workers' compensation.
