Info

There is a significant I/I response throughout the Port’s wastewater collection system, which leads to design flow peaking factors greater than the industry standard in most locations. In general, though, the majority of sewers in the Port are currently sized with sufficient capacity to convey existing design flows. This assumes, however, that the existing sewers are free of sediment buildup, fats, oil, and grease (FOG) build up, large debris, and other capacity limiting materials. Excessive build up in a sewer will restrict flow, which can lead to sewer backups and SSOs in severe cases. 9.2.5 Capacity Enhancement Measures Figure 9.1 illustrates the proposed sewer improvements required to correct existing deficiencies and to accommodate future growth in the Port. This section summarizes the projects shown on Figure 9.1, while Table 9.3 contains specific details related to each project. 9.2.5.1 The majority of sewers within the Port contain sufficient capacity to accommodate existing and future design flows without exceeding the established capacity criteria. There are a few exceptions where existing sewers will need to be replaced by larger diameter sewers, or parallel sewers will need to be constructed to bypass flow around hydraulically deficient sewers. The decision as to whether a particular sewer should be replaced or a parallel sewer constructed should be made during the preliminary design phase. This study assumes that deficient sewers will be replaced. 9.2.5.2 Pipeline Capacity Improvements Lift Station Replacement or Rehabilitation Visual inspection of the Port’s sanitary sewer lift stations was performed on March 5 and 6, 2010 as part of this study. More detail is provided in Appendix M. Lift station replacement or rehabilitation will be necessary to maintain proper operation of existing facilities and to meet the requirements of the Environmental Protection Agency’s (EPA’s) Administrative Order. Therefore, we assumed that each lift station in the Port would be rehabilitated or replaced by the year 2030 and beyond. The rehabilitation and replacement projects were phased considering the findings of the visual inspections such that the costs associated with these projects were distributed as evenly as possible through year 2030 and beyond. Required capacities for each lift station are identified for each lift station in Table 9.3, based on the requirement that each lift station be equipped with sufficient firm capacity to pump the design flow.
