Does snow melt or rainfall activate large amounts of infiltration and inflow (I/I) in your wastewater collection system? Do you have the associated sewage back-ups, overflows and treatment plant problems? Identifying and locating I/I in sewer lines can be an expensive and time-consuming challenge for any operator, engineer or supervisor of wastewater operations. This one-of-a-kind class can equip you to better meet the challenge. You can save days of work and possibly thousands of dollars by better understanding when and how to look for extraneous flows with state-of-the-art techniques.

Basic thru Intermediate

Topics include: * Summary of Clean Water Act regulations and why they fail to control extraneous flows *excessive sewer system extraneous flow * The need for accurate field inspection and office records * Recognizing how crisis sewer cleaning and other problems cause sanitary sewer overflows * Reviewing the influence of rainfall, soil conditions and topography on extraneous flow rates * Evaluating the influence of private building service connections (PBSC) on sewer system extraneous flows * A review of flow measurement equipment and field use * Projecting extraneous flow removal efficiencies * Internal manhole and pipe inspections (mini camera, mainline camera and man entry)

Municipal utility personnel, collection system operators, maintenance personnel and public works personnel
