Maine · Cumberland County
15 businesses are based in Cumberland County on the DEP Category C transporter list dated September 1, 2026.
DEP has not replaced the active non-haz transporter PDF since that date. Businesses close, change hands and let licences lapse in that time, so treat this as a starting list rather than a current register. Confirm the Category C licence is still current before you book.
Maine requires a DEP Category C non-haz transporter licence to pump a septic tank and haul the waste. DEP publishes a base city, not a county and not a promised service area; the county here is where that city sits. Each card also shows the expiry DEP printed on this roster.
3 businesses on this page are filed under a village name rather than the official town; the cards still map to Cumberland County.
These businesses give base cities around FALMOUTH, GORHAM, HARPSWELL, HARRISON, NEW GLOUCESTER, PORTLAND, STEEP FALLS, WEST BALDWIN, WESTBROOK, WINDHAM. DEP publishes a business name, address, city, state, phone, Category C and an expiry date, and the list itself is dated September 1, 2026. DEP does not print a licence number on this roster.
Portable-toilet, construction and municipal crews hold this licence too. 8 of 15 here name septic or cesspool; the rest are flagged so you can confirm household septic tank pumping first.
