Wastewater Treatment Plant Improvements

Description

The project entails improvements to the City of Yreka’s Wastewater Treatment Plant (WWTP), wastewater disposal fields, and Lift Stations (LS) 1, 2, 3, and 4. Improvements at the WWTP include upgrades to the headworks; replacement of surface aerators and diffusers; improvements to the secondary clarifiers; electrical improvements; installation of a fiber optic line from the corporation yard to the control building; expansion and renovation of the control building; demolition of the chlorine contact basin, filtration facility, and SOMAT facility; construction of a new disinfection facility and a new filtration building; installation of a sludge dewatering facility; replacement of the lift station; and installation of supervisory control and data acquisition (SCADA) equipment. Improvements in the disposal fields include replacement of the control building, moisture sensors, solenoid control valves, and concrete valve boxes, installation of new electrical conduit and pull boxes, and installation of a roof-mounted antenna on the new control building. At the lift stations, antennas on ground-mounted poles, cables, and radios would be installed, and minor modifications would be made to the existing control panels to support the SCADA system.
