Sewer Rehabilitation Strategy Workshop - Updated for 2011!

Location: Hilton Americas Hotel

Cost: $125, $75 each additional person from the same company

 

Presented by noted engineering managers and researchers George Kurz of Barge Waggoner Sumner & Cannon, and Pat Stevens of ADS Environmental Services.

 

This "how-to" workshop will equip people for starting an I/I reduction program. The information will also provide valuable benchmarks for people who are actually conducting programs.

 

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 (percent 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, TN.
