Krista Ka usen, estimates were developed for the agreed upon improvements for each facility and the PE, ENV SP projects were phased over a five-year period. (Continued) Rosecrans Booster Pump Station Replacement Project - Buena Park, CA: Project Engineer for this project, which involved construction of a new pump station at the site of the existing Rosecrans Booster Pump Station in order to serve residents and properties in the upper zones of the Buena Park potable water system. Original pumping capacity was less than 3,500 gallons per minute (gpm), which did not meet peak -hour (3,531 gpm) or maximum -day -plus -fire (5,395 gpm) demands. The newly constructed 1,949-square-foot pump station building includes four separate rooms: pump room, electrical room, generator room, and disinfection room. The project also required grading for vehicle turnaround space, installation of a detention basin, and a surge tank pad. Keith Reservoir - Corona, CA: Project Engineer for preparation of onsite pipelines, valves and mechanical design for a proposed 2.5 MG prestressed concrete reservoir. Design included 16-inch inlet/outlet piping, valve vault, reservoir mixing system, 16-inch overflow pipe and 12-inch drain line. Scope of services included preliminary design report, construction plans, specifications and bidding and construction phase engineering. Laguna Sewer Lift Station Rehabilitation - Laguna Beach, CA: Project Engineer for preparation of construction plans and specifications for rehabilitation of the Laguna SOCWA sewer pump station and other improvements. The existing wet well was in a deteriorated condition and required rehabilitation of all interior concrete surfaces and installation of a new PVC liner. Various improvements included sewage bypass plans, site improvements, odor control system, mechanical piping and valve replacements, manholes and sewer pipelines. Hidden Hills Booster Pump Station Final Design - Yorba Linda, CA: Project Engineer for preparation of construction plans and specifications for the Hidden Hills Booster Pump Station Improvements project for Yorba Linda Water District. The project includes the replacement of a small 250-gpm jockey pump, motor, and appurtenances with an 1,800-gpm VFD pump, modifications to existing pump station building including the addition of new electrical room and new roof, and the design of on -site emergency standby Natural Gas engine -generator system. Coto de Caza Life Station Emergency Storage Basin - Coto de Caza, CA: Project Engineer for preparation of a preliminary design study, final design, contract bid documents, and engineering services during construction for the construction of an ESB at the existing Coto de Caza Lift Station. The 45-foot x 38-foot x 25-foot deep cast -in -place reinforced concrete basin is designed to contain sewer overflows from the lift station during emergency events. Project includes coordination of an existing SDG&E power supply line relocation, site improvements to allow tanker truck access to the ESB, including relocation of entrance gate and site walls/fences, and design of overflow and drain pipelines. The ESB is designed to contain three hours of the lift station's average daily flow within three interior chambers. The sewage is transferred among the chambers by two to HP submersible pumps and a series of sluice gates. The design includes electrical and instrumentation improvements to monitor and control the ESB chamber levels.
