Documenting the Effectiveness of Greencastle, Indiana's Private Property Inflow and Infiltration Policy

This study is a peer review of the City of Greencastle, Indiana policy to reduce I/I from private property sources. The study reviewed the policy which requires certified inspectors to document that privately owned properties do not contribute excessive rain water to the sanitary sewer system. The study demonstrates that Greencastle’s private property I/I policy delays and reduces the sewer system’s response to rainfall by analyzing monitoring and operational data. It describes a low-cost municipal approach to control private property I/I and presents statistical techniques that analysts can use to quantitatively document the effectiveness of I/I reduction programs.
