Colville is the Stevens County seat, sitting where US-395 meets SR-20 in the Colville River valley, with the Colville National Forest on one side and farm country on the other. Kettle Falls, up the highway, lives on Lake Roosevelt — the wide Columbia River reservoir — and Addy is hay fields and acreage along the river bottom. Outside the small town cores, every one of these communities runs on septic: ranch houses, lake cabins near the Lake Roosevelt shoreline, and manufactured homes on five-acre parcels all have a tank in the ground and nobody to call when it acts up.
Stevens County septic systems are overseen by the Northeast Tri County Health District, which serves Stevens, Pend Oreille, and Ferry counties. Pumping records and inspection reports on jobs we schedule are done to NETCHD's standards by the performing crew, so your paperwork is right when the county asks for it — or when a buyer's lender does.
Full pump-outs for tanks of all sizes, with a condition check of baffles and the effluent filter while the tank is open. 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. The performing crew handles the county paperwork.
Slow drains, soggy ground over the tank, alarms, and effluent filter issues — diagnosed properly before anyone quotes you a bigger job. Crews handle lids, risers, baffles, filters, and lines.
Sewage backing up is not a "next week" problem. Call us and we'll get a crew moving.

Most Colville-area homes pay $400–$600 to pump a standard 1,000-gallon tank. Tank size, lid depth, and truck access set the exact price; the crew confirms a firm price before any work starts. For a fuller breakdown, see our septic pumping cost guide.
The Northeast Tri County Health District (NETCHD) is the local health officer for Stevens, Pend Oreille, and Ferry counties. It keeps the county's on-site sewage rules, approves and permits pumpers, and receives inspection reports for Colville, Kettle Falls, and Addy properties.
Most buyers and lenders ask for one now, and from February 1, 2027, Washington's rule (WAC 246-272A-0270(1)(k)) requires an inspection by a third-party inspector authorized by the local health officer at property transfer. Inspections typically run $300–$450. See our guide to Washington's 2027 septic inspection rule.
Washington rules set inspection intervals at every 3 years for conventional gravity systems and every year for alternative systems. Staying on that cycle also keeps you ahead of the 2027 property-transfer requirement.
