West Yost designed improvements to most of the City of Jackson’s wastewater treatment plant to address new regulatory requirements and aging infrastructure. Improvements included conversion of existing oxidation ditches to simultaneous nitrification-denitrification with improved aeration control and instrumentation, construction of a new disc filter facility, conversion from chlorine disinfection to UV disinfection using inclined lamp configuration, changing from belt press dewatering to screw press dewatering, construction of a new electrical building and MCC capacity, up-sizing electrical service to the facility, and installation of a new standby generator.
