📞 Call (509) 463-4972Backups & alarms — call now. Routine pumping — book today and we'll get you scheduled.
Full pump-outs for tanks of all sizes, with a condition check while we're in there. Most homes need it every 3–5 years — if you don't know when yours was last pumped, it's time.
Buying or selling a home on septic? Washington will require a third-party inspection at property transfer from February 1, 2027 — and most lenders and buyers already ask for one. We also schedule routine O&M inspections: every 3 years for conventional gravity systems, annually for alternative systems, per Washington rules. The performing crew handles the county paperwork.
Slow drains, soggy ground, pump alarms, effluent filter issues — diagnosed properly before anyone quotes you a new system.
Building on rural land or replacing a failed system? Installations are scheduled in the Sandpoint, Rathdrum, Bonners Ferry and Spokane-fringe areas — ask when you call and we'll tell you straight whether installs are covered where you are.
Sewage backing up is not a "next week" problem. Call and we'll move fast — that's the whole point of a local service.
No games. Typical ranges for our area — you'll get a firm price from the crew before any work starts:

Out here, a septic system isn't a line item — it's your whole wastewater system, and when it fails it's your problem the same day. We know the health-district rules in Spokane, Stevens, Pend Oreille, and Ferry counties in Washington and Bonner, Boundary, and Kootenai counties in Idaho because we coordinate work under them across the region, and we tell you the price range before anyone rolls a truck. When you call us, we take your details and schedule your job with a local crew permitted by your county health district; the crew that does your work confirms your price before they start.
