By installing additional membrane cassette equipment, the plant can readily expand to 4.0 MGD, which the City is already permitted for. The new plant, an Ovivo Kubota flat plate MBR system and the first of its kind in coastal Georgia, is able to treat up to 3 MGD – double its previous capacity of 1.5 MGD.

As the Engineer of Record for the City’s original wastewater treatment plant, Hussey Gay Bell was once again engaged by the City to provide overall planning, design, permitting, and construction oversight services for the new plant to replace the existing plant which had exceeded its useful life.Īs the largest single expenditure in the City of Richmond Hill’s history, Hussey Gay Bell was able to assist the City with securing $500,000 of direct loan forgiveness from GEFA via green credit by embracing energy efficiency through the design of VFDs, blower automation and gravity flow through membranes.Ĭompleted in 2016, the Sterling Creek project generally consisted of the planning, design and construction of a new 4.0 million gallons per day (MGD) five-stage biological nutrient removal and membrane bioreactor (MBR) plant. As a result, the City ultimately entered into a consent order with the Georgia Environmental Protection Division for non-compliance of the existing 1.5 MGD overland flow constructed wetlands treatment plant that required the design and construction of a new treatment facility. The wetland speciation changed significantly over time and resulted in violations of ammonia from the plant effluent. The City’s original wastewater treatment plant with overland flow fields and constructed wetlands was built in the 1990s.
