UNSPSC 47101531: Septic tanks

UNSPSC 47101531 Septic tanks is a Commodity code covering routine pumping, cleaning, maintenance, inspection, repair, and emergency response services for septic systems at state and local government facilities. Recent solicitations show state transportation departments, fire agencies, water resource authorities, county parks and museum operations, and transit maintenance facilities purchasing these services through competitive procurement. The work spans routine service cycles (typically monthly or semi-annually), emergency 24/7 response capabilities, system inspections and monitoring, tank cleaning and effluent filter replacement, leach field observations, and associated disposal and hauling. Contractors must typically hold state septic tank cleaning permits, motor carrier permits, hazardous waste credentials where required, and appropriate contractor licensing (often C-42 Sanitation System or equivalent). Prevailing wage requirements apply in most state procurements when bid amounts exceed stated thresholds.

California Department of Transportation (Caltrans) appears as the dominant repeat buyer, with multiple recent IFBs posted across regions: septic tank pumping and disposal in Santa Barbara, Monterey, and San Luis Obispo Counties (IFB 05A3035, due September 22, 2026); lift station and septic services across Alameda, Contra Costa, Marin, and Solano Counties (IFB 04A7594, due September 1, 2026); services in San Bernardino and Riverside Counties (IFB 08A3999, due July 14, 2026); and Fresno, Kern, and Tulare Counties (IFB 06A3316, due July 9, 2026). CAL FIRE and the California Department of Water Resources also solicited recently, as did the California Highway Patrol. Outside California, the State of Rhode Island (Division of Purchases) issued a three-year Master Price Agreement (MPA 414 OE) for septic and drain services effective August 1, 2026, and Jefferson Patterson Park and Museum in Calvert County, Maryland solicited pump-out services (RFQ BPM058034, due August 19, 2026). Sarasota County, Florida posted a quote request for septic system abandonment services. Small business and disabled veteran business enterprise preferences and incentives appear consistently across California procurements, typically at 5 percent preference caps and 3–5 percent DVBE participation requirements. Geographic concentration is heavily weighted to California, with secondary activity in Maryland and Florida. Caltrans contracts typically run three years (October 1 through September 30), require no subcontracting, and price services on a per-gallon basis with separate line items for routine and non-routine service frequency and quantity bands.
