A Screening Assessment of the Potential Impacts of Climate Change on Combined Sewer Overflow (CSO) Mitigation in the Great Lakes and New England Regions

This report presents the potential implications of climate change on combined sewer overflow (CSO) mitigation in the Great Lakes and New England Regions. It is not a detailed analysis of individual systems in these regions. The purpose of this assessment was 1) to determine whether the potential implications of climate change on CSOs in these regions warranted further consideration and study, and 2) to evaluate the need for decision support tools and information that would enable combined sewer system (CSS) managers to incorporate the consideration of climate change into their decision making processes. Wastewater treatment infrastructure was identified as a priority concern because of the essential service provided by these systems to protect public health and ecosystems. Additionally, investments in wastewater treatment infrastructure are long-term, capital-intensive, and often, irreversible in the short- to medium-term.
