Comprehensive upgrade of an existing wastewater treatment facility to incorporate advanced membrane bioreactor (MBR) technology, improving treatment capacity, efficiency, and effluent quality. The project included new process tanks, sludge handling systems, chemical feed facilities, electrical buildings, and extensive yard piping, along with phased demolition and rehabilitation of existing infrastructure. Construction was carefully sequenced to maintain continuous plant operations, integrating new biological treatment trains, equalization capacity, and disinfection systems within an active facility.
