He has been in responsible charge of the preparation of feasibility studies and facilities master plans; preliminary and final dcsign documents (constmction drawings, specifications, and cost cstimates); and constmction supervision of canals, pipelines, wells, pump stations, reservoirs, reclaimed water use systems, and agricultural crop and landscaping irrigation facilities. Relevant Project Experience City of Bellflower, Water Master Plan, CA: Project Manager for the development of overall water master plan for the City. With a population of approximately 64,000 people, it is served by six watcr companies. A comprehensive hydraulic computer model was developed combining all six systems. Thc adequacy of each system was evaluated along with recommcndations for combining the systems. Recommendations were provided regarding the facilities and financing altcrnativcs. City of Simi Valley, Hydraulic Computer Model, CA: Project Manager for the dcvelopment of a hydraulic computer model for the system, serving approximately 12,000 customers through 125 miles of pipelinc with scven pressurc zoncs. The project consisted of preparing a hydraulic computer model using Cybernct calibrating and ficld testing the model. Cadiz/Fenner Conjuntive Use and Storage Program, San Bernardino County, CA: Project Manager for the development of preliminary engineering and economic analysis for a conjunctive use, water storage and transfcr program located in Cadiz and Fenner Valleys of San Bernardino County. The Corc Program could provide a dry-year water supply to the Metropolitan Water District of Southern California of up to 100,000-acre fcet per year. The program concept is to convey Colorado River water from the Colorado River Aqueduct (CRA) to the Cadiz/Fenner area during periods of excess supply. The imported water would be stored in the local groundwater aquifer system. This water and indigenous groundwatcr would be extracted by wells and returned to the CRA during periods of drought. San Juan Basin Groundwater Management Plan, CA: District Engineer and Project Manager for the San Juan Basin Authority in developing a groundwater management plan. The goal of the Plan was to develop a groundwater management plan maximizing the use of the Basin's storage capacity in conjunction with artificial and natural recharge. A mathematical model of the groundwater basin was developed incorporation basin hydraulics as well as water quality. Various groundwater management scenarios were simulated. Water production facilities were identified including 16 wells and an 8-MGD desalting plant. A detailed financial and economic analysis was mack for the project, \\hich included capital operation and maintenance and lifecycle cost of the desalter and other facilities.
