<br /> - ' Jill, <br /> setup) and attempt to T.V. the line up to the original obstruction. Payment will be made <br /> for manhole to manhole footage. <br /> H. Lift Station Performance Testing <br /> The lift stations will be tested to establish actual vs. design discharge capacity. Pump <br /> performance will be evaluated for each pump and combination in order to identify <br /> possible causes for system deficiencies, flow restrictions, and ability to transport <br /> collection system flows. <br /> Lift Station Performance Testing will be performed on approximately three (3) lift <br /> stations. Depending on pump station design, motor selection and force main location, <br /> one of the following methods will be utilized to determine pumping capacity of each <br /> station: <br /> .. ' <br /> 1. Portable Non-Invasive Doppler Ultrasonic Flow Measurement - station pumping <br /> capacity to be determined by measuring flow on full pipes (force main). <br /> 2. Draw-down Tests - § "draw-down" test will involve volumetric analysis over <br /> typical pumping cycles to compare against the rated pump performance. At <br /> least two (2) tests will be performed. . <br /> I. Source Defect Analysis <br /> 1. All field data collected will be input into a software program for analysis (PIPE@). <br /> PIPE@ (Physical Inventory Point-Source Evaluation) is a data inventory and <br /> defect analysis tool which will be used by ADS to inventory and prioritize each <br /> defect. <br /> 2. All identified structural and maintenance defects, and physical data collected <br /> during the field inspection phase will be' inventoried and analyzed. Data from <br /> existing reports, maps, as-built drawings, etc., may also be provided and <br /> incorporated into the database. <br /> 3. The CITY has the option to obtain this program for general operation and <br /> maintenance of the sewer system. <br /> J. Final Report <br /> Following the completion of all field activities, three (3) copies of a comprehensive draft <br /> report will be provided to the CITY presenting a summary of all field and office <br /> activities, results of analyses, and recommendations. <br /> G:\OA LLAS\CO NTRA ClìSMA R C bô.
