NIGP 91070: Sludge Removal, Building (to Include Grease Trap Cleaning)

NIGP 91070 Sludge Removal, Building (To Include Grease Trap Cleaning), an Item code, represents the pump-out, cleaning, routine maintenance, and disposal of grease traps, lift stations, lint traps, grit traps, and related interceptor systems at municipal, state, county, school district, and institutional facilities. State and local governments procure this work as a core asset-preservation and regulatory-compliance function—most solicitations require quarterly or bi-monthly service cycles and 24/7 emergency response capability, often backed by TCEQ Sludge Transporter Program registration or equivalent state permitting. Issuing bodies span state supported living centers and state correctional facilities (Texas Health and Human Services Commission, Illinois Department of Corrections, Oregon Department of Corrections, Texas Department of Criminal Justice), county departments and utilities (DeKalb County Watershed Management, Marion County Solid Waste, Lowndes County), city public works and water departments (San Antonio, Fort Worth, Phoenix, Albuquerque, Temple), school districts (Portsmouth Public Schools, Douglas County Schools in Georgia, Northside Independent School District), and higher-education institutions (University of Houston, Sam Houston State University). Representatives of recent opportunities include the Texas Health and Human Services Commission's solicitation for grease trap waste removal and sludge removal at Corpus Christi State Supported Living Center (IFB HHS0017428V3, bids due August 25, 2026), DeKalb County's three-year multiyear contract for annual sanitary sewer and manhole cleaning with Local Small Business Enterprise set-aside (PE64400NONST2027000000287, bids due November 9, 2026), and the City of Phoenix's five-year vactor services requirements contract under DBE-N compliance (IFB 27-0462, offers due October 19, 2026).

Activity concentrates in Texas (TDCJ, HHSC, City of San Antonio, City of Fort Worth, West Travis County Public Utility Agency, City of Temple), Georgia (DeKalb County Department of Watershed Management, Douglas County Schools, Lowndes County Board of Commissioners, City of Albuquerque regional footprint), Florida (City of Oviedo mobile centrifuge sludge dewatering, Solid Waste Authority of Palm Beach County biosolids operations), and California (Sacramento County Water Agency, County of San Mateo Department of Public Works). Work spans emergency water removal, 24-hour on-call response protocols, mobile centrifuge dewatering services, CCTV inspections, hydrojetting, video recording documentation, confined-space entry compliance, and integrated waste disposal with manifesting and environmental permitting. Many solicitations carry prevailing-wage requirements, local small-business or disadvantaged-enterprise set-asides or preferences (LSBE in DeKalb; DBE-N in Phoenix; HUB utilization targets in Texas HHSC and TDCJ), First Source Jobs Ordinance compliance (DeKalb County), or state-resident or local-vendor preferences (Texas, New Mexico, California). Contract terms typically run twelve to thirty-six months with optional renewals; pricing is firm-fixed per-gallon, per-unit, or hourly with CPI or federal minimum-wage escalation clauses at issuing-body discretion. The market sees steady baseline demand and elevated activity around institutional, utility, and school-district asset-lifecycle renewal windows—currently strong in October 2026 with multiple bid deadlines compressing across state and municipal buyers.
