Oregon · Clatsop County
4 businesses hold a DEQ Sewage Disposal Service pumper licence and have published addresses that map to Clatsop County, checked September 6, 2026.
OAR 340-071-0600 requires a DEQ Sewage Disposal Service licence to pump a septic tank in Oregon. DEQ issues Installer, Pumper and Installer/Pumper licences, and only the last two may pump — every business here holds one of those. 2 of these hold a Pumper licence and the rest hold an Installer/Pumper licence. Oregon publishes an expiry date for every licence, so each card shows one.
DEQ publishes a business address, not a county, and not a service area. The county on a card is where the business address sits, worked out from Census place and county data — an Oregon licence is valid statewide, so a business in the next county may well serve your address.
These businesses are based around Astoria, ASTORIA, Seaside. DEQ publishes a licence number, business name, address, phone, email and — unusually — the licence expiry date, so you can check the licence is still current before you book rather than after.
Plumbing, excavation and portable-restroom firms hold this licence too. Every business on this page names septic in its name.
