Waste Water Facilities Plan Update

This presentation outlines the required update for the Wastewater Facilities Plan as mandated by federal and state regulations. It examines existing infrastructure, projected population growth, and analyzes flow projections over the next 20 years. Major changes since the last plan in 1972/1973 necessitate this update, particularly due to aging infrastructure and consent decrees. Stakeholders include various environmental agencies, and public feedback is integrated into the approval process. The recommended alternatives for improvements focus on river watershed treatment plants and necessary upgrades.
