UNSPSC 47101539: Sludge or sewage removal equipment

UNSPSC 47101539 Sludge or sewage removal equipment is a Commodity code encompassing the transport and hauling of liquid sludge and raw wastewater generated at treatment facilities. State and local governments buy liquid sludge hauling services to move wastewater byproducts from treatment plants to disposal or receiving facilities, with scope typically including tanker truck transport, spill cleanup, regulatory compliance, and per-gallon or unit-price compensation. The issuing bodies are primarily state environmental agencies and special-purpose water and wastewater authorities managing multiple treatment plants. The Maryland Environmental Service has posted the bulk of recent activity under this code, issuing multiple competitive sealed bids for liquid sludge and raw sewage hauling across central Maryland facilities.

Recent solicitations show active procurement in Maryland and California. The Maryland Environmental Service issued an IFB (solicitation 1262665, due June 29, 2026) for liquid sludge hauling at four wastewater treatment plants in Washington and Frederick Counties, designating the procurement as Small Business Reserve with an estimated annual volume of 586,000 gallons and a mandatory pre-bid conference on June 5. A concurrent multi-step sealed bid (solicitation BPM057205, due June 29, 2026) for the same four facilities requires Phase 1 technical acceptance before Phase 2 price evaluation, with electronic submission through the MES Procurement Portal. Earlier, MES solicited liquid sludge hauling for six central region facilities (solicitation 1262625, due May 26, 2026) transporting approximately 309,000 gallons annually to the Freedom District WWTP, and a separate procurement for raw sewage hauling at Stevenson University (solicitation 1262415, due February 23, 2026) with an estimated 3.2 million gallons annually at 24-hour on-call response. The California Department of Water Resources issued IFB 10214188 (due June 9, 2026) for water treatment system services—inspection, maintenance, repair, and installation across four field divisions—requiring General Engineering Contractor licensure and five years' verifiable experience, with a mandatory pre-bid on May 26, 2026, in Byron and bids due June 9. A single Yuma County, Arizona biosolids removal and disposal opportunity (RFB26339, due August 6, 2026) appears minimally documented and lacks sufficient detail to assess scope or issuing body.
