La Honda Pescadero Unified School District, California

BEI provided engineering design for a transmission pipeline to provide potable water to the La Honda Elementary School in La Honda , California. The transmission pipeline consisted of flow metering, a backflow prevention device, a booster pump station, and over 3,000 feet of 4-inch pipeline. The design also included a jack and bore under Highway 84. The control system was designed to maintain 60 pounds per square inch water pressure at the school.

Cuesta La Honda, California

BEI provided engineering design for a surface water treatment system to provide high quality water for potable use in an area with a creek and spring water supply. The treatment system consisted of a membrane filter system followed by chlorination. The control system was designed to provide control screens on a desk top computer to allow data logging of the important parameters and easy downloading of the data to reports for submittal to the Department of Health Services. The project also included sizing and design of a 250,000 gallon reservoir and permitting.

City of Pleasanton, California

BEI was retained by a private developer to design a 1.4 million gallon steel tank and improvements to an existing pump station to supply water for the upper pressure zone of the Ruby Hill development in the City of Pleasanton. The project included preparation of plans and specifications for the tank, site improvements, addition of three 50 HP pumps to an existing pump station and related electrical and control systems. Control of the pumps is provided by a radio telemetry system that is linked to a central control system at the City of Pleasanton Utility Center. A detailed hydraulic analysis that included the water supply system to the pump station as well as the piping between the pump station and storage tank was carried out to confirm pump selection and assure the City that the system would perform efficiently under all expected operating conditions.

Private Estate, San Benito County, California

In order to provide high quality water for potable and irrigation use in an area with highly mineralized groundwater, BEI planned and designed a reverse osmosis water treatment system. Brine disposal is by percolation to an aquifer that is not connected to the one supplying the water to the system. The project included preparation of plans and specifications for the reverse osmosis treatment system, piping, valves and controls. Following construction, BEI was retained to operate and maintain the system.
