All members voted in favor. Motion passed. Minutes approved. Lakewood Interceptor update City Engineer Papke explained the purpose and function of the city's interceptor. The interceptor is a large underground tunnel that runs beneath Edgewater Drive and intercepts sewer flows and directs them to the wastewater treatment plant(WWTP). Flows are treated at the WWTP before that are discharged into Lake Erie. The interceptor plays an important role in preventing combined sewer overflows. Mr. Papke displayed a map which illustrated that 75% of the city's flow moves through the interceptor. Construction on the interceptor took 27 years —lasting from 1918 through 1945 — and was performed using hand tunneling. Mr. Papke remarked further on the physical characteristics of the interceptor. The interceptor is accessed via 12 manholes, or access points. Mr. Papke explained that the interceptor received a comprehensive inspection and rating in 2011- 12. Areas of the interceptor were rated on a scale of 1-5, with five being poor conditions. This August, the city noticed atypical overflow that were happening more frequently. Upon investigation, areas of roof collapse and deterioration were found in areas previously rated 3 or 4. Since then, the city's contractor has performed more than 35 repairs. These repairs should only be considered band-aids, as the interceptor has exceeded its useful life. Mr. Papke stated that the city needs to plan for the next century with a comprehensive solution. He discussed various options and spoke in detail about the proposed solution to install a slip lining that is cured in place. The lining would provide approximately 100 years of useful life. As part of the project, 21 new access shafts would also be installed. Mr. Papke discussed the cost breakdown of the project, which totals $26.4 million. He discussed potential funding sources including ARPA, OPWC and other grants. He proposed a timeline for design and engineering in 2022 and bid and construction in 2023. 1
