Holistic Sewer Rehabilitation - Measures of Effectiveness

摘要

The objective of this paper is to provide an introduction to methods of evaluating effectivenessof efforts to reduce Rainfall Derived Infiltration and Inflow (RDII) and present results of severalrecent rehabilitation projects. The explanation of methods is intended as a primer for those whoare preparing for or considering the evaluation of flow data for rehab effectiveness. Methodsdiscussed range from basic hydrograph reviews, to storm data evaluation and the use of controls.being rehab programs or are considering… practical engineering applications… and theircomplications . Results from 7 rehab projects and phases are presented with peak RDII reductionranging from 14% to 61% and RDII volume reductions ranging from 42% to 70%.
