  13. Other Project Components • Roads and Bridges • Wetland Mitigation • Reservoir Clearing • Transmission Lines • High Point Eastside Discharge Relocation

  14. Water Treatment Plant • Initially Sized for 12 MGD – Expandable to 48 MGD • Current production capacity of 14.7 MGD • Future expansions will be based on partners’ needs • State of the Art Filtration Technology – triple barriers of protection – concerns about High Point’s Eastside WWTP & Seaboard Chemical Site • Awarded State AWOP Certification in 2015, 2016 & 2017 • Solely a water wholesaler – No retail customers • Onsite Certified Laboratory – routine water quality sampling – contract testing
