A standard reference for all sewer system professionals. The third edition of this industry bible shows you how to develop a comprehensive sewer system. evaluation and rehabilitation program. The book explains how. to design successful rehabilitation programs, apply processes. for evaluation and rehabilitation, and appraise the results. This. updated classic features new material on tools and methods. for pipe evaluation, infiltration and inflow problems and. detection, rehabilitation materials and methods, and effective. repair methods.

Fully revised and updated, this authoritative volume offers the most comprehensive information available on maintenance, repair, rehabilitation, and replacement of existing sewers. This definitive guide covers sewer evaluation and monitoring, sewer rehabilitation methods and materials, and quality assurance. The Fourth Edition features new material on tools and procedures for pipe evaluation, infiltration and inflow problems and detection, rehabilitation materials and methods, and effective repair techniques. It is intended to be a comprehensive and useful source of practical design information for the practicing design professional. This is a must-have resource for all sewer system professionals. This manual of practice covers Current regulations and guidelines Capacity, structural, and maintenance-related problems Site inspection and testing Methods of structural evaluation, including closed-circuit television, sonar, and laser-based scanning Sewer flow monitoring and sewer system hydraulics Infiltration and inflow source detection Selection of sewer rehabilitation methods and materials Evaluation of sewer rehabilitation effectiveness documentation and quality assurance

The purpose of this research project was to examine construction projects that successfully reduced Rainfall Dependent Infiltration/Inflow (RDII). The research began with a literature review of all published records describing RDII removal projects. Initially, the review identified many projects; however, subsequent evaluation of available information revealed several important realities. First, most RDII removal projects in the country go undocumented. Second, of the RDII removal project summaries that have been published, few provide good data. Third, data gathering and analyses for this report were hampered by lack of documentation, lost or unavailable monitoring data, and weaknesses in monitoring techniques. Projects with sufficient information describing the conditions before the RDII removal project received a detailed analysis. In all, the case studies from the six agencies presented in this report (1) document before-and-after RDII levels, (2) quantify the RDII reduction achieved, and (3) describe the cost-effectiveness of the removal. As more than one project was documented for some agencies, a total of 12 RDII projects received review. The projects examined include both those that ?successfully? reduced RDII and those that did not. In general, the conclusion was that utilities run the risk of not removing significant RDII unless they address private sewer laterals. The only cases examined where significant RDII was removed were those that addressed private sewers or inflow sources. A major recommendation of this report was to establish a standard reporting protocol for documenting RDII removal projects. This protocol details what specific information should be provided when documenting an RDII removal project and how to perform an evaluation of RDII removal effectiveness. The protocol touches on issues ranging from flow meter maintenance to statistical analysis of flow data. By using the proper documentation recommended in this report, communities allow others who are preparing to perform similar work to examine and utilize the results of any RDII removal project.
