Licensed septic pumper directory (official state registries)

Instead of building our own contractor list, this directory points you to the government registries that license septic pumping and septage hauling businesses. These are the agencies' own records, so they are more current than any list we could keep. It currently covers ten states (Washington is listed with a King County example because the state approves pumpers at the county level). Licensing works differently in each state, and in many states it's handled by counties, so a missing state doesn't mean pumpers there are unlicensed. Each link was checked on November 8, 2026.

State	Agency	What the registry covers	Registry
Minnesota	Minnesota Pollution Control Agency (MPCA)	Subsurface sewage treatment system (SSTS) businesses. Pumpers hold the "Maintainer" license. MPCA notes that licensed businesses may work anywhere in the state.	SSTS business search
Florida	Florida Department of Environmental Protection (DEP)	Registered septic tank contractors and contracting businesses. DEP says the search is updated daily. County health departments still handle permits.	Search for a contractor (DEP page)
Pennsylvania	Pennsylvania DEP	Businesses that pump septic tanks or haul residential septage must register with DEP. Registered haulers display a 5-digit transporter number on their trucks.	Active hauler list, Sept 2026 (XLSX)

Washington	Washington State Department of Health; local health departments	The state requires septic pumpers to be approved by the local health department, not a single statewide roster. King County publishes a certified liquid-waste pumper/hauler list (valid through Dec. 31, 2026). Check your county health department if you live elsewhere in Washington.

Alabama	Alabama Onsite Wastewater Board (AOWB)	The board examines, licenses and regulates people who manufacture, install, service or clean onsite wastewater systems, including pumpers. Search the licensee roster.	AOWB licensee roster search

How to use a registry

Get the business's legal name and, where used, its license or transporter number from the quote or the truck.
Search the registry and check that the license is active and covers pumping or hauling.
If you can't find a record, ask the business for its license number, or contact the agency.
Then compare prices using our cost guide and the questions to ask.

Septic Service Scout doesn't add, remove, or rank businesses, and it doesn't endorse anyone in these registries. MPCA says its search results aren't intended to be used as advertising. Inclusion in a registry shows licensing status only, not quality.
