Abstract A study was conducted to identify and analyze present practices for determining and controlling infiltration and inflow (I/I) and investigate the role of roots and tide or backwater gates in the I/I problem. It was found through on-site investigations and questionnaires that local authorities were just starting to consider their I/I problems. Roots were found to be a major sewer system problem. Tide gates were found to be considered satisfactory, although generally they receive infrequent maintenance and often do not properly close. The results of the study are presented in four volumes. The first report (EPA-600/2-77-017a) reviews a sample economic analysis and information concerning root control and tide gates as determined by the study. This volume of appendices to the report contains the literature review, questionnaires used, and field reports on root control and tide gate conditions and practices.
