' 15 <br />9 <br />L GENERAL <br />A��inar}, design study was compleud to determine the costs to inczease PumP�B <br />capacities of Lift Station Nos. 7 and 8• The re�°c�u°�d� �Provements include the <br />following: <br />A. Lift Station No. 7 <br />1. Capaciry - Increase &om pumping capacity to 1.1 MGD. <br />2. Provide standby power. <br />3, provide option to incorporatc odor con�ol in funue. <br />B. LiftStationNo.8 <br />1. Capacity - Increase from pumpin8 capacity to 4.6 MGD. <br />Z, provide forcemain capacity to uansfer flows to "D" uunk. <br />3. Provide standby power. <br />4. Address noise concerns. <br />5. Address odor concems. , <br />(, Address aesthetic concems. <br />II. TASK 1: PRELII�IINARY PLAMVING <br />Reaoonsibilitin of E_ o�ineer <br />This task will provide the final planning for the upgrade of the lift stations and will <br />include the following: <br />1. Review system hydraulics and confirm alignment of forcemain co connect Lift <br />Station No. 8 with the "D" trunk• Tlus `Mll include obtaining confirmin8 in�ert <br />elevations and overflow elevations for interceptors connecring to the "D" trunk• <br />2, prepare flow schematic of system with maximum capacity of lines without <br />overflows. Evaluate altematives for modifying overflow elevations if required, to <br />ma•cimize transfer capaciry of system to the "D" trunk• <br />3, Complete geotechnical investigations required for strictural improvements at Liit <br />Starion No. 8. <br />4, prepaze first floor, intermediate level and lower level floor plans for Lift Station <br />Nos. 7 and 8. <br />5, Prepaze equipment list and cut sheeu for equipment including centrifugal pumps> <br />Sump pumps, valves, HVAC equipment, electrical panels and RTU's. <br />(, prepaze electrical one-line diagram and control strategy for both LiR Station Nos. <br />,79 7and8. <br />M� �� ,997 A_l LiftStarionNos. 7& 8 Upgradu <br />
