UPDATED FOR 2010! -This workshop teaches a strategy for conducting a successful municipal sewer rehabilitation program for SSO and I/I reduction. The strategy is based on extensive before-after flow measurements for 27 project areas which included 95 miles of sewer lining, and manhole and service lateral rehabilitation on all lined sewers. The strategy proved the value of the System Approach for comprehensive rehabilitation of deteriorated sewers targeted in priority basins - rather than a "find-and-fix" approach for scattered individual pipe defects. Municipal sewer O&M savings generally resulted in a pay-back period of about 10 years for project construction costs. The approach has been formulated into a logical and intuitive 10-step strategy. Pitfalls for flow monitoring and the analysis of monitoring data will be explained. New material this year will include a comparison of methods to determine rehabilitation effectiveness. The popular method of using "R" values (% of rainfall volume that enters a sewer line) will be compared to the Standardized Procedure which was used to document successful I/I removal in Nashville. This is a "how-to" seminar that will equip people for starting an I/I reduction program and the information will also provide valuable benchmarks for people who are actually conducting programs. Presented by noted engineering project managers and researchers George Kurz of Barge Waggoner Sumner & Cannon, and Pat Stevens of ADS Environmental Services. The full day workshop includes lunch, hand-outs and CEU/PDH credits
