Septic pumping in Allison: 1 septic company has an address in town, and 12 more sit within 30 miles. 10 matched to the Iowa license list.
✓ means we found the company on the Iowa DNR Licensed Septic Tank Cleaners (Pumpers), dated 08-19-2026. "No match" does not mean unlicensed. Names and phone numbers on a state list often differ from the ones in ads. Ask for the license number.
Before you call. Ask for the total price and which fees can be added: digging up or opening the lid, extra sludge, a trip charge. Ask if they pump every compartment through the main lid and check the baffles. Ask for the license or permit number, then compare it to the one on this page. If the pumper says you need a repair, get three written quotes before you agree.

Order: companies matched to a state list first, then listings with more complete data (phone, website, street address), then by name. Nobody pays for a spot on this page, and a company can fix or claim its listing free.
The EPA says household septic tanks are typically pumped every three to five years, and it puts routine maintenance at $250 to $500.
