New Wastewater Treatment Milestone at the Bio Station

In August 2025, the Flathead Lake Biological Station celebrated the ribbon cutting of its new Membrane BioReactor sewage treatment facility — complete with a ceremonial “toilet paper” ribbon.

This state-of-the-art system treats wastewater to a high standard before it returns to the environment, safeguarding the lake from nutrient pollution and bacterial contamination. Learn more about the facility and its environmental benefits in the Bio Station’s announcement.
