About this file
This document outlines Amendment 0005 to contract N4008521R0052 for the P1043 Water Treatment Plant Replacement project at Marine Corps Base Camp Lejeune in North Carolina. The amendment revises technical specifications for the membrane system and vertical turbine pumps. It increases the suction can diameter for membrane feed pumps to 24 inches and maximum suction can length to 12 feet. It also replaces specifications for transfer pumps and a filter backwash supply pump. The $8 million project constructs an 8 million gallon per day water treatment plant utilizing membrane filtration to comply with regulations and address saltwater intrusion threats. The facility will be owned and operated by the Department of the Navy Naval Facilities Engineering Command.
