Recent Raw Water Main Failure Pipe Failure Temporary Bypass Pipe Raw Water Main Pipe Failure Repair Efforts
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 2015- Pender begins IBT process IBT requests 14.5 MGD Source water is the Cape Fear River via LCFWSA EMC approval was anticipated for 2017 Raw Water Intake Cape Fear River Raw Water Pump Station Lock & Dam No. 1
