Project #1027

Identifying Technologies and Communicating the Benefits and Risks of Disinfecting Wet Weather Flows

Moffa & Associates ( A Unit of Brown and Caldwell)
Disinfection Byproducts (DBPs)
Combined Sewer Overflows (CSOs)


The primary objective of this project was to identify and communicate the benefits and risks of disinfecting wet weather flows by evaluating the effectiveness of available disinfection technologies and identifying disinfection by-products and their potential risks to aquatic and human life. A decision-making framework was developed that could be used as a model to guide combined sewer overflow, sanitary sewer overflow, and stormwater disinfection control policies. The project also provided a summary of a disinfection demonstration test plan, which subscribers can use to design their own disinfection demonstrations, as it may be necessary for municipalities to perform site-specific disinfection demonstrations to fill data gaps and develop and implement a risk communication plan.

Originally funded as WERF project 00-HHE-6.
