Carried. 2. Member Comments / Concerns: None a. Consider Modifications to the Agenda — None 3. Town Wide Sanitary Sewer Study Presentation/Discussion: Mr. Weber gave a summary of background information regarding the agenda item. The study was done to look at the town's existing sanitary sewer system and projections to identify what basis exists for moving forward with other assessments. The Larson Group presented an Executive Summary Report which provided background, methodology, results, and recommendations generated from the study. It addressed pipe capacity calculations, existing system flow modeling, modeled peak inflow, existing system capacity, I&I comparison, future build -out, future system capacity, and recommendations. In summary, the town's system is in good condition. Recommendations include consideration to improvements and/or I&I reductions to key gravity main segments in capacity issue areas, consider a formal I&I study, consult the model for future development, do minor pump station improvements, and continue flow monitoring and maintenance of data. The presentation, and the URL demonstrated in the presentation, will be sent to the attendees and presented to the Town Board on March 25th. Mr. DePaolo expressed his concern regarding the use of a full build -out scenario versus a trend line growth analysis. Brad Sick explained that the model could be used for specific areas of concern by entering more specific data for a more realistic scenario. Ms. Hunter identified a typographical error on page 27 in regard to capacity percentage. It should be 30%, rather than 303%. Mr. Goodman added that the Town Board would need to decide if there will be an expansion capacity policy for or whether expansion would be handled on a case-by-case basis. He reminded the group about the flow meters that will be installed at the Town/City boundary for more accurate flow monitoring. Mr. Thaete reported that in a snapshot monitoring situation, it appeared that the town is contributing 38%, but paying for 42% of flow. He suggested following the recommendation to do a formal I&I study in order to determine what is causing an impact rather than automatically upsizing pipes. Mr. Goodman explained that the Special Joint Committee of the Ithaca Area Wastewater Treatment Plant meets quarterly and plans to monitor I&I from all municipalities. 4.
