Naval Facilities Engineering Command, Hawaii’s (NAVFAC) Potable Water Utilities section recently completed a 10-inch waterline along Wasp Boulevard on Ford Island.

The project included the installation of approximately 650 feet of 10-inch cement-mortar-lined, polyethylene-wrapped ductile iron-pipe to replace a 6inch cast iron pipe that was installed in the 1920s and was prone to breaks. Crews started working late August and completed it at the end of September.

The new line provides a robust link to water distribution systems recently installed as part of the National Oceanic and Atmospheric Administration (NOAA) building. 130 upgrade and the NOAA Pacific Regional Center (PRC) construction at former hangars 175 and 176. It also offers a much needed upgrade to the distribution system serving the Naval Undersea Warfare Center (NUWC) facilities in the area.

Installation of the new waterline enabled more than 1,200 feet of 16-inch cast iron installed in the 1920s to be taken off of the active potable water system.

To date, almost 98 percent of the circa 1920s 16inch transmission loop on Ford Island has been removed/replaced. This project is part of NAVFAC Hawaii potable water utilities’ recapitalization program to replace aging lines in the Joint Base Pearl Harbor-Hickam water system.
