When wastewater collection systems experience poor performance due to issues such as age, lack of capacity, design and maintenance problems, the results are usually predictable–overflow, cave-ins, and customer complaints are most common. A sewer system that is experiencing excessive overflows must be addressed quickly and efficiently.
Professional rehabilitation recommendations should be implemented to manage any complex wastewater utility efficiently. CES staffs licensed engineers who develop these interactive decision support tools on an as-needed basis, as directed by the client to support their engineers.
A rehabilitation method and estimated cost for repair of each defect within a collection system will be identified from the data provided from a sanitary sewer or storm system evaluation. Each defect will receive an estimate of its inflow/infiltration potential, or it will be identified as a “structural defect” that affects only the pipe integrity and is currently not considered a significant source of inflow/infiltration. The final report will prioritize the related defects to develop an effective rehabilitation plan. A priority ranking of each deficiency will be presented along with the recommended method of rehabilitation and estimated rehabilitation cost. The final report summarizes (by priority) the location and suggested plan of rehabilitation, which is referenced back to the field documentation and photographs. This enables CES to provide our clients with an easy to use product that is both highly informative and concise.
