�a�Proposal - Project Understanding and scope -of -Mork 1-56 RD -1 thru RD -11 Record Drawings W -66, Sheets 1 through 11, dated 10/15/1962, James M. Montgomery, Consulting Engineer The pumping station, pumps, motor, piping and valves will be housed in a masonry block building. The building will also house auxiliary equipment and systems such as electrical and control panels; and a sodium hypochlorite disinfection system. A constant speed, line -shaft vertical turbine pump will be designed to meet the requirements of ANSUAWWA E101 (AWWA Standard for Vertical Turbine Pumps — Line Shaft and Submersible Type) and the Hydraulic Institute Pump Standards. Pump selection will consider the pump station characteristics, demand, to determine the appropriate pump capacity. The target design capacity of the pump station is 2,500 gallons per minute. The pump station piping will utilize the existing piping system to the extent posible including the pump control valves: on the discharge pipeline and on the startup (flow bypass) pipeline that will discharge through a new pipeline and connect to the local storm drain. The scope will be based on using the SCE electrical power supply to the City's West Pump Station. Metcalf & Eddy will provide voltage and load calculations and will coordinate efforts for SCE to provide the transformer, meter and service panel and activate electrical service to the station. The proposed design will provide technical speci*.icatic�ns for instrumentation -lid control enabling the City to monitor and control the p�:mping station operation_ locally at the pump station site and remotely through the existing SCADA system. The input /output points will include pumping station pump control, discharge pressure and flow, reservoir water level and operational status and alarms. New equipment will be specified to match City's specifications Integration of the reservoir operation and equipment status into the existing SCADA system will be described in the plans and technical specifications. The PLC will provide local automatic control capabilities, as well as communication via radio to the central computer system for remote monitoring and control. The UO list and other system requirements will be established in conjunction with City staff and review of City's existing SCADA characteristics, Design Documents — Metcalf & Eddy will conduct a site visit and meet with the City to clarify project needs prior to beginning design for equipping the pump station facility. Available information, such as previous site - specific studies, the City's standard details, and other similar projects performed for the City will also be reviewed. Metcalf & Eddy will prepare drawings and technical specifications for the equipping of a new pump station and building, including architectural, mechanical, structural, Company Confidential • Trade Secret and proprietary Information a(Afetcalf& Eddy, Inc.
