The scope will involve the design and construction of a new wastewater facility that encompasses primary, secondary, and tertiary treatment with key components including headworks, clarifiers, a rotating biological contractor or moving bed biofilm reactor, ultraviolet disinfection, aerated sludge digestion or biological sludge conditioning, sludge dewatering, and ventilation upgrades. A back-up generator will be added or relocated to support the plant and existing lift stations.
