(SEH®) appreciates the opportunity to provide this scope of services for the <br />Gem Lake MCES Connection Analysis. Thank you for reaching out to SEH to assist with this important <br />sanitary sewer monitoring and flow evaluation effort. We understand the City is interested in better <br />understanding actual discharge conditions to the MCES interceptor system so that future coordination <br />and planning can be supported by measured flow data. <br /> <br />PROJECT APPROACH <br /> <br />The goal of this work is to determine the actual discharge to the MCES interceptors by metering the two <br />primary connection points. SEH will install two laser meters for a six-month monitoring period and <br />complete routine meter reading and cleaning to maintain usable data throughout the monitoring period. <br />Following data collection, SEH will review the monitored flow information to evaluate dry weather and wet <br />weather sanitary sewer response and identify inflow and infiltration characteristics. This scope is focused <br />on flow monitoring and data analysis; hydraulic modeling is not included. <br /> <br />TASK 1 – PROJECT MANAGEMENT & MCES COORDINATION <br />You will receive project coordination throughout the monitoring and analysis effort, including project <br />startup, invoice coordination, and routine status updates as needed. SEH will participate in a kickoff <br />meeting to confirm monitoring objectives, meter locations, schedule, access needs, and coordination <br />requirements before field work begins. <br /> <br />SEH will also coordinate with MCES through two meetings during the project. These meetings are <br />intended to confirm monitoring expectations, discuss available connection data, and review data needs <br />for the final analysis. <br /> <br />Deliverables: Meeting coordination, project status updates, and MCES coordination support. <br />
