The 2.5-MGD San Francisco International Airport (SFO) Mel Leong Wastewater Treatment Plant consists of sanitary and industrial wastewater treatment operations. This project scope includes the rehabilitation and replacement of existing industrial primary and secondary wastewater treatment processes, replacement solids dewatering and handling facilities, construction of a new 8,000-SF administrative and laboratory building, and construction of new recycled water treatment processes and storage facilities. This project upgrades current facilities to treat 1.6 MGD of industrial wastewater and first flush stormwater to a higher quality by installing state-of-the-art Dissolved Air Flotation and Trickling Filter treatment technologies. This will positively increase the water quality effluent released to the bay.
