This paper considers an approach to inflow and infiltration (I/I) correction, as currently adopted by Gwinnett County. Through a project implemented in the Jack’s Creek area of Gwinnett County, the paper examines the costs of an I/I program focused on correcting manhole defects and its corresponding impact on the reduction in inflow. The benefits of this more pragmatic approach are compared to the more comprehensive methods involving CCTV, dye testing and smoke testing.
