Clallam County Environmental Health is offering free DIY septic inspection classes in November and December of 2017.

The Septic 201 Do-It-Yourself (DIY) Self-Inspection classes provide an overview of the “what, why and how” of safely inspecting your septic system and include an instructional video, a brief demonstration and a short exam.

Classes are held at the Dungeness River Audubon Center at Railroad Bridge Park, 2151 W. Hendrickson Road, from 5:30-7 p.m. Wednesday, Nov. 8, and 5:30-7 p.m. Wednesday, Dec. 6.

Pre-registration for classes is required and available online through www.clallam.net/septic or by calling the Clallam County Environmental Health Department at 360-417-2258. Spaces are limited.

Septic inspections are required by state law. Conventional gravity septic systems need to be inspected every three years; all other systems need to be inspected annually.

County officials remind septic system users that pumping is not the same as an inspection.

Not all septic systems are eligible for homeowner inspection, and systems located in the Marine Recovery Area — between Bagley Creek watershed and the eastern county boundary — must have an initial inspection by a licensed septic inspector.
