IDENTIFYING WHERE REHABILITATION IS COST-EFFECTIVE IN A SANITARY SEWER SYSTEM TO MANAGE SSOs
Abstract:Rehabilitation of deteriorated pipelines and laterals can be a cost-effective method of maintaining capacity and preventing Sanitary Sewer Overflows (SSOs) within a collection system. The cost-effectiveness of rehabilitation will depend on the extent and magnitude of Infiltration and Inflow (I/I). Rehabilitation must also be compared to other methods (e.g. conveyance improvements, storage, and treatment) to assess its costs and effectiveness to control I/I within an entire sewer system. Therefore, it is paramount to identify where I/I is occurring to be able to quantify if rehabilitation will be cost-effective. This paper presents a new method for identifying where I/I is occurring and how cost-effective rehabilitation is when compared to other alternatives.
