Pender County Water Plant • September 2006 - Pender purchases 6 MGD raw water supply from LCFWSA • 2012 – Pender County Water Treatment Facility is Completed • Pender WTP permitted at 2 MGD but readily expandable to 6 MGD

Pender Inter-Basin Transfer • EMC approval was anticipated for 2017 Raw Water Pump Station er Source water is the Cape Fear River via LCFWSA Riv • Raw Water Intake ar IBT requests 14. 5 MGD Fe • pe 2015 - Pender begins IBT process Ca • Lock & Dam No. 1
