R. Scott Foster, P.E. <br />Education <br />Principal <br />B.S., Civil Engineering, Lehigh <br />University, 1988 <br />Scott Foster is the Principal and Owner of Scott Foster Engineering, <br />Experience <br />Inc. He has over 30 years of experience performing hydraulic <br />33 years <br />modeling and analysis of pipeline surges and transients for over 700 <br />Professional Registrations <br />systems in both gravity and pressure pipeline systems, including <br />Professional Civil Engineer <br />water hammer and pipeline failure due to loss of power to pump <br />CA C50860 <br />stations, turbine units, valve operations, and pipeline breaks <br />UT 5587955-2202 <br />throughout the United States. He has extensive experience designing <br />WA 38053 <br />surge control devices such as surge tanks, standpipes, vacuum relief <br />OR 67001PE <br />valves, surge relief and surge anticipator valves, and flywheels in <br />CO 45608 <br />addition to developing flow control, pump station, and turbine <br />NV 17199 <br />operation parameters to reduce the effects of pressure surges. <br />HI 10424 <br />AZ 36737 <br />As a recognized expert in the field, Mr. Foster has performed forensic <br />Tx 115203 <br />analyses and field testing of systems related to pipeline failures and <br />GA PE036044 <br />NC 52696 <br />operational issues to identify the causes and recommend measures to <br />eliminate the problems. He has participated in multiple value <br />Professional Memberships <br />engineering studies requiring the review of surge analyses performed <br />ASCE <br />by other consultants using commercially available computer programs <br />AWWA <br />and verifying these results using programs different from those <br />employed in the analysis. He has served as an expert witness on water <br />hammer issues and conducted numerous presentations to private and <br />governmental agencies on water hammer and pressure surges. <br />Relevant Experience <br />Diamond Valley Lake/Inland Feeder, Riverside County, CA <br />Metropolitan Water District of Southern California <br />Scott was responsible for the hydraulic analyses and evaluation of the effects of pressure surges <br />associated with the operation of the system's twelve 175-cfs reverse pump/turbine units and associated <br />pressure control structure, together with the PC-1 pressure control structure for flows in excess of 1,100 <br />cfs. He also performed hydraulic and pressure surge analyses and recommended surge protection <br />measures for up to an additional 400 cfs from the San Bernardino Valley Municipal Water District's <br />Redlands Pump Station pumping into the Inland Feeder for delivery to MWD and San Bernardino Valley <br />Municipal Water District facilities. <br />Allen McCulloch Pipeline/OC-88 Pump Station, Orange County, CA <br />Metropolitan Water District of Southern California The sudden failure of a 66-inch diameter PCCP <br />section of the Allen McCulloch Pipeline (AMP) led to a forensic analysis of the cause of the failure and <br />solutions to prevent a repeat event. As part of this project, MWD decided to direct connect the 150 cfs <br />OC-88 Pump Station to the AMP, necessitating a surge analysis to prevent the operation of the pump <br />station from adversely impacting the AMP. Scott performed a detailed hydraulic and pressure surge <br />analysis to determine the cause of the failure of the AMP. He recommended new valve operating times <br />to prevent maximum HGL elevations from exceeding the allowable during multiple system operations. <br />He then analyzed the surges created through the direct connection of the 150 cfs OC-88 pump station <br />and 55 cfs turbine facility and recommended the installation two 23 ft diameter pressurized spherical <br />SCOTT FOSTER ENGINEERING, INC. 1 of 3 <br />
