Description Update treatment processes to better conform with pending regulation. The scope of this project will be informed by the Treatment Study (CIP W3321)

Justification Forecasted regulations include PFAS, Magenese, stricter lead and copper rules, continued intrusion of nutrient runoff, and heavy metal reductions. Climate change will also continue to cause carbon producing processes to increase operating costs. Due to these factors a treatment study will be commissioned in 2024 to evaluate the existing unit processes employed by the treatment plant and make recommendations for changes to better conform with climate change and new regulation. Our expectation is to move away from lime softening and employ membrane filtration.
