Existing septic tanks must be bypassed and backfilled or removed; they may not be connected into the collection system.

Each answer was extracted from an official source and independently re-checked against that source by a second reviewer. That is an evidence check, not legal advice. Rules change; confirm with the authority before you buy or build.
Unanswered questions are usually a sign that Forks publishes no rule on the point, not that none exists. Clallam County’s page lists the county offices to call.
