Major Infrastructure Improvement Projects Completed in 2020-21

American River Canyon South Booster Pump Station Variable Frequency Drive Replacements (Retail) – This project involves the replacement of the existing aged and obsolete Variable Frequency Drives (VFD’s) at the ARC-South BPS.  VFD’s are used in an electro-mechanical system to adjust the speed and torque output of an electric motor.  The VFD powers an electric motor, in this case the pump motor, and changes the pump speed by varying the frequency and voltage supplied to the electric motor.  In the case of the District’s booster pump stations VFD’s are used to drive pump motors at the appropriate speed to match the water demand.  Use of VFD's in the District's pump stations reduces electricity costs and reduces wear and tear on the pumps, which increases their reliability and service life.  This project will replace the aged VFD's at this pump station along with the necessary ancillary wiring and components.

Water Treatment Plant Residual Area Lift Station Project (Wholesale) – This project will make improvements to the solids handling system at the Treatment Plant.  The project includes completing some grading of the existing solids drying area, and constructing a new lift station and piping to recycle collected water back into the existing equalizations basin.  Work for this project includes completing the necessary electrical power and instrumentation and control improvements for the new recycle lift station.

Hinkle Reservoir Tank Project (Wholesale)

The District is moving forward with a major improvement project that includes the rehabilitation of the District’s Hinkle Reservoir.  The 62 million gallon drinking water reservoir was lined and covered in 1980.  The cover and liner have outlived their useful life and need to be replaced.  To assist with operational control during the project, two large temporary tanks will be installed on the District’s property just beyond the main gate. These bolted steel tanks, as seen in the rendering above, are currently under fabrication and are scheduled to be erected by November 2020.  The two tanks are temporary and will be removed once the project is completed. We expect completion in spring/summer of 2023.
