17. Factory pump curves for all currently active pumps (or the most recent pump <br />performance data available). <br />18. Emergency connections to any outside water sources (location, sizes, minimum and <br />maximum flow rates, delivery pressure). <br />19. Current (as of January 1, 2013) locations of all pressure plane boundaries (including the <br />location of all closed valves). <br />20. Any TTHM or HAAS data collected since the IDSE Report in 2007 <br />21. Water loss data. <br />22. Any TCEQ Notices of Violation and copies of the annual TCEQ system inspections, audits <br />or other regulatory advisement. <br />B. Existing Data Analysis <br />1. Analyze existing data and identify any data gaps. <br />2. Compare the GIS flies received to the 2007 IDSE hydraulic model. Identify discrepancies <br />between the 2007 model and the GIS files. <br />3. Rectify any data gaps or discrepancies found in (a) and (b) using mobile technology <br />verification with sub -meter accuracy. Work (field and data analysis) associated with <br />mobile technology verification is expected to require a maximum of 24 hours. <br />C. Develop Field Testing Plan <br />1. Pump performance testing protocols, Including unit efficiency study. <br />2. Prepare sub - agreement with electrical subcontractor for pump performance testing. <br />3. Hydrant flow test locations and protocols. <br />4. Locations of pressure data recorder deployment. <br />5. List of system data (Including SCADA) needed for period of testing. <br />D. Supervise /Conduct Field Testing <br />1. Conduct tests to determine individual pump performance curves and combined unit <br />efficiencies. Testing will be performed as a joint effort between the ENGINEER, CLIENT <br />and subcontractor selected by ENGINEER and approved by CLIENT. <br />The following pumps will be tested: <br />a. Oakridge Pump Station —4 pumps <br />b. Soyars Pump Station — 4 pumps <br />c. McCarty Pump Station — 3 pumps <br />d. Comanche Pump Station — 4 pumps <br />e. High Service Pump Station at SWTP — 3 pumps <br />2. Supervise hydrant flow tests. Testing will be performed by City staff. <br />3. Pressure data recorder deployment and recovery. <br />4. Prepare a technical memorandum summarizing the results of field testing. <br />E. Develop Preliminary Existing System Model <br />1. From available information collected in Task A, update the 2007 IDSE hydraulic model to <br />reflect infrastructure present on January 1, 2013. <br />2. From available information collected in Task A, adjust the 2007 IDSE hydraulic model to <br />reflect current demand distribution. <br />3. Input operational controls in place on January 1, 2013. <br />4. Make preliminary model runs to determine order -of- magnitude accuracy level. <br />
