Field staff will complete biweekly <br />meter reading and cleaning visits to maintain equipment performance and verify that the collected data <br />remains suitable for analysis. <br /> <br />At the end of the monitoring period, SEH will remove the meters and compile the monitoring record for <br />use in the inflow and infiltration review. This task assumes the selected monitoring locations are <br />accessible and appropriate for laser meter installation. <br /> <br />Deliverables: Flow monitoring data collected over the monitoring period. <br /> <br />TASK 3 – DATA ANALYSIS <br />SEH will review the monitored flow data to evaluate dry weather and wet weather sanitary sewer <br />response. The dry weather analysis will establish baseline flow conditions during periods without rainfall <br />influence. The wet weather analysis will compare monitored flow response during rainfall or snowmelt- <br />influenced periods to identify potential inflow and infiltration trends. <br /> <br />SEH will summarize the results in a technical memorandum. The memorandum will document the <br />monitoring approach, summarize dry weather and wet weather findings, and identify key observations <br />from the collected data. No hydraulic modeling is included in this scope. <br /> <br />Deliverables: Technical memorandum summarizing dry weather analysis, wet weather analysis, and <br />inflow and infiltration observations. <br /> <br />ASSUMPTIONS / EXCLUSIONS <br />This scope assumes two laser meters will be installed for a six-month monitoring period. The data will be <br />analyzed for inflow and infiltration only, and no modeling is included. The City’s GIS data is assumed to <br />be current and suitable for use in supporting the analysis. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />
