Subtask 6.2 Develop Options to Increase Time to Overflow For each lift station, RMC will assess the potential for increasing the amount of time the station may be out of service before a surface overflow occurs. At a minimum,this will include the following: • Evaluate the impact of modifying pump station controls to maximize available storage • Evaluate the feasibility of installing overflow pipelines from the station wet well to adjacent sewers, or through passive diversions in the collection system upstream of the pump station • Evaluate the potential for wet well expansion or the addition of on-site emergency storage • Assess potential for the addition of permanent standby power or emergency pump connections, where not already present Based on the above evaluations, RMC will recommend options for increasing time to overflow at each lift station, including conceptual level estimates of the cost of the options. Task 6 Deliverables: • TM on Lift Station Reliability Evaluation including time each station may be off line without an overflow, potential options for increasing time to overflow, and conceptual estimates of costs of the options. Task 6 Schedule: • All items delivered by September 30, 2013 Task 7–Review of Sewer Maintenance, Inspection,and Rehabilitation Programs This task involves working with the City to evaluate its current sewer system operation &maintenance (O&M), inspection, condition assessment and rehabilitation programs, and helping the City develop business processes to effectively and efficiently manage its collection system. Subtask 7.1 Conduct Staff Interviews and Prepare O&M Assessment RMC will conduct interviews with City staff responsible for various aspects of collection system maintenance and management. The interviews would be scheduled to take place over a two-day period and include personnel involved in all aspects of sewer system management, including O&M staff and others responsible for data management, FOG control, review of inspection data, and rehabilitation decision-making. Based on these interviews, RMC will prepare an assessment report(TM)summarizing the findings of the assessment and identifying areas for potential improvement. Subtask 7.2 Prepare Workload Estimate and Staffing Plan Based on data collected during the two-day site visit and follow-up data requests, RMC will prepare a workload estimate and staffing plan to support prioritization of maintenance activities and identification in changes to staffing and equipment required to meet the overall goals for maintaining the sewer system. Subtask 7.3 Develop Condition Assessment and Rehabilitation Decision Process RMC will review the current approach utilized by the City to assess sewer condition and determine rehabilitation needs. RMC will work with City staff to develop a well-documented and objective decision process to identify the specific defects requiring corrective action, along with specific maintenance, repair, rehabilitation,or replacement methods to employ to address defects identified through CCTV inspection. The decision process will be focused on correcting severe structural defects and areas of excessive maintenance demand.
