Wastewater Treatment Plant Improvements

Project consists of a comprehensive upgrade to the wastewater treatment plant including but not limited to, the following: selective demolition of existing components of the influent channel and grit chamber, trickling filters, recirculation pump building, chemical building, secondary clarifiers, chlorine contact tank, anaerobic digesters, solids dewatering facility and solids storage facilities and various other selective demolition components. The construction of a new screening building and mechanical upgrades for grit removal. The construction of a new landfill leachate storage tank and ancillary mechanical improvements including but not limited to feed pump, mixers and level control devices. The conversion of existing rock media trickling filters to plastic media biotowers and associated tankage. Construction of a new secondary clarifier and improvements to existing secondary clarifiers. Construction of a new chlorine contact disinfection chamber and new bulk chemical storage building. Modifications to existing chlorine contact tank for miscellaneous treatment processes. Construction of miscellaneous improvements to existing anaerobic digesters. Upgrades to existing mechanical solids dewatering process. Improvements to existing sludge drying bed pole barns. Miscellaneous improvements including replacement of hand rails, roof replacement, fencing, drainage, and grading. Work includes general site construction, concrete/masonry tankage and building construction, equipment installation and process piping, electrical construction, plumbing construction, HVAC construction, Instrumentation and Controls overall Supervisory Control and Data Acquisiton (SCADA) System.
