Elk and Chattaroy are unincorporated Spokane County communities along the Little Spokane River, along US-2 toward Newport. This is five-acre country: wells, wood stoves, long gravel driveways — and a septic system on every property, because there is no municipal sewer in these unincorporated areas. Colbert, down the highway toward the Green Bluff farming area, and the rural fringe around Mead and Mount Spokane are the same story, a mix of older farmhouse systems and newer homes on acreage.
All of it is Spokane County, so on-site sewage systems here are overseen by the Spokane Regional Health District. We schedule the pumping and inspections, and the performing crew handles the county paperwork the way the Health District wants to see it.
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.
Building on acreage in the Elk–Chattaroy area or replacing a failed system? New installations are available across the Spokane fringe — ask when you call and we'll tell you straight what your lot needs.
No games. Typical ranges for the area — you'll get a firm price from the crew before any work starts:

Most homes in Elk, Chattaroy, and Colbert pay $400–$600 to pump a standard 1,000-gallon tank. Price depends on tank size, lid depth, and how far the truck has to reach. The crew confirms a firm price before any work starts.
Most likely, yes. Most buyers and lenders require one today, 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 when a property with a septic system is sold or transferred, with limited exemptions set by your health district. The local health officer can also remove the requirement when the district has evidence of a recent compliant inspection. Inspections typically run $300–$450. See our guide to Washington's 2027 septic inspection rule.
Washington rules require an inspection every 3 years for conventional gravity systems and every year for alternative systems. The Spokane Regional Health District oversees on-site sewage systems in Spokane County, including Elk, Chattaroy, Colbert, and Mead.
An alarm means the tank level is too high or too low and the system needs attention soon. Cut back water use, don't ignore it, and call us — alarms in the Elk and Chattaroy area are one of the most common calls we get, and catching it early is far cheaper than a backup.
