96-Inch Sewer Replacement or Renewal: A Case History
This paper describes the case history of the field investigations, modeling, condition assessments, identification and evaluation of alternatives, design, bidding, and construction of a major sewer project in Cedar Rapids, Iowa. Cedar Rapids is a vibrant community in central east Iowa with a population of 140,000. The robust industrial development creates wastewater discharges equivalent to a population of 1,300,000. Corrosion observed at the treatment plant generated concerns about the conditions of the upstream sewers. The three most critical trunk sewers in the city were selected for inspection and evaluation. This work was performed in two phases. The first phase included liquid sampling, limited internal inspections, airspace monitoring, sewer air flow and sulfide modeling, recommendations for second phase inspections, sewer rehabilitation, and sulfide and odor control. The second phase focused on detailed inspection and evaluation of the 96-inch diameter Main Interceptor Sewer, which was prioritized due to concerns with its condition and the consequences associated with its failure. Information gathered from the second phase inspections was used to identify and evaluate multiple alternatives for replacement or rehabilitation of 4,400 feet of the lowermost 96" diameter Main Interceptor Sewer.
