A Comparative Analysis of Sewer Rehabilitation Strategies - Application, Selection, and Performance in Practice

摘要

This paper presents an objective comparison of a number of completed rehabilitation projects in the United States that have been placed in-service over the past 30 years. Available results concerning application, performance, and overall performance were evaluated to assess the applicability, selection, and design considerations of various rehabilitation strategies. This evaluation was based on the performance of completed sewer rehabilitation projects as determined by effective flow monitoring activities. Using the results of this evaluation, the authors have characterized driving factors which influence overall performance of sewer rehabilitation projects by reducing the impact of sanitary sewer overflows (SSOs) and rain-dependent inflow and infiltration (RDII).
