SRHD regulates Spokane County

Spokane County on-site sewage systems are overseen by the Spokane Regional Health District. The Northeast Tri County Health District covers Stevens, Pend Oreille, and Ferry counties. The line matters on the north edge of the county. A Deer Park mailing address can sit in Spokane County or across the line in Stevens County. Check the parcel's county before you hire a company. The Deer Park page and the Elk and Chattaroy page cover those neighborhoods. Seller steps are in the transfer checklist.

Sewer in town, septic on acreage

Much of the city of Spokane, and parts of Spokane Valley and other cities, are on municipal sewer. Septic systems are the usual system on acreage: the rural edges of Liberty Lake, Cheney and Medical Lake outside city sewer, Nine Mile Falls, Newman Lake, the Mead fringe, and the five-acre country at Elk and Chattaroy. The city of Deer Park itself has municipal sewer. The acreage around it generally does not. If you are not sure which you have, ask the Spokane Regional Health District or the city utility.

Routine inspections, then the February 1, 2027 sale rule

Washington already requires routine operation-and-maintenance inspections: every 3 years for a conventional gravity system and every year for an alternative system, under WAC 246-272A-0270(1)(e). Those inspections are done by a provider the health district has approved, and that company handles its paperwork with the district.

Beginning February 1, 2027, Washington also requires an inspection when a property with a septic system is transferred, under WAC 246-272A-0270(1)(k). The inspector has to be a third-party inspector authorized by the local health officer. In Spokane County, the Spokane Regional Health District asks sellers for an inspection by a permitted operation-and-maintenance provider completed within the past 12 months. Read SRHD's property transfer inspection requirement. The statute text is WAC 246-272A-0270. The plain-language walk-through is Washington's 2027 septic inspection rule.

SRHD's listed exemptions are narrow: a system permitted and operational within the past 12 months, an operation-and-maintenance inspection within the past 12 months, or a system that was abandoned and connected to sewer. Confirm those on SRHD's page. They can change.

The public lists

Choose a company on SRHD's permitted-pumper list or operation-and-maintenance provider list. The pumper PDF linked from SRHD was marked updated August 2026 when this page was checked on October 25, 2026. SRHD says the health district does not endorse, recommend, or warrant the work of any sewage system pumper. Lists change. Use the district's page, and ask the company to confirm it is still permitted for the service you need. A pumper permit and an operation-and-maintenance provider permit are not the same approval.

New systems

A new system or a replacement starts with a permit from the health district and an approved installer. In Washington, site evaluation follows WAC 246-272A-0220. Confirm with the district who may evaluate the lot.

What does it cost?

Pumping and inspection prices vary with tank size, how deep the lids are, and how far the truck must travel. Ask the company for a written price before work starts.

Frequently Asked Questions

Who regulates septic systems in Spokane County?

The Spokane Regional Health District regulates on-site sewage in Spokane County. The Northeast Tri County Health District covers Stevens, Pend Oreille, and Ferry counties, not Spokane County. A rural Deer Park mailing address can fall on either side of that line, so check the parcel's county. Elk, Chattaroy, and the acreage outside city sewer in the county follow SRHD.

What does the February 1, 2027 rule mean for a Spokane County seller?

Beginning February 1, 2027, WAC 246-272A-0270(1)(k) requires an inspection by a third-party inspector authorized by the local health officer when a Spokane County property with a septic system is transferred. SRHD asks for an inspection by a permitted operation-and-maintenance provider within the past 12 months. The seller files the report with SRHD. Read SRHD's transfer page and the Spokane County checklist for the current steps and fee.

How often does Spokane County require a routine septic inspection?

WAC 246-272A-0270(1)(e) calls for an inspection every 3 years for a conventional gravity system and every year for an alternative system. In Spokane County those inspections go through a provider permitted by the Spokane Regional Health District. The same intervals apply in Elk, Chattaroy, the Mead fringe, and rural acreage around Deer Park that sits inside the county line.
