Septic Systems Spark Debate in Flathead County
11 Feb
Summary
- Proposed septic rule changes may allow gravity systems not permitted since 2004.
- Residents and groups raise concerns about water quality impacts.
- Health board to review public comments at February 12 meeting.

The Flathead City-County Health Board is reviewing public feedback on proposed revisions to septic system regulations. A key point of discussion is the potential reintroduction of gravity septic systems, which have not been permitted in the county since 2004. Environmental Health Manager Jim Wardensky noted that some board members view gravity systems as a viable option, especially for remote rural residents lacking electricity.
However, numerous residents and advocacy organizations have submitted comments expressing strong opposition. They argue that permitting gravity systems represents a regression in septic standards and raises serious concerns about the impact on water quality, particularly in areas with high groundwater and proximity to surface water. The Montana Department of Environmental Quality indicates that uniform pressure systems outperform gravity-flow systems.
Former Health Department head Joe Russell and Citizens for a Better Flathead are among those urging the board to maintain higher treatment standards. They cited studies indicating how septic systems can negatively affect local waterways. The board's meeting on February 12 is expected to address these diverse public opinions and deliberate on the proposed regulatory updates.
