JOINT BASE PEARL HARBOR-HICKAM, Hawaii – The U.S. Navy will begin flushing water lines at the Pearl City Peninsula military housing neighborhood on Dec. 20 in accordance with the Drinking Water Distribution System Recovery Plan.
In preparation for flushing the system, the Navy is assembling the Granulated Activated Carbon (GAC) filtration equipment that has been delivered over the past week. The GACs will be connected to fire hydrants, and the filtered water will be discharged to storm drains with Hawaii State Department of Health and U.S. Environmental Protection Agency oversight.
In accordance with the Water System Flushing Zone Map, Pearl City Peninsula will be flushed first to serve as the safe test case given its proximity to the Waiawa well, which has been the source of the Navy’s drinking water since securing the Red Hill and Halawa wells on Nov. 28 and Dec. 3, respectively. Flushing of the distribution system at Pearl City Peninsula is expected to take one day. The Summary Map can be found at https://www.cpf.navy.mil/Portals/52/Flushing-Plan-Graphic-V6-19DEC21.pdf.
Following a successful test, the distribution systems in the Army housing areas of Red Hill and Aliamanu Military Reservation (AMR) will be the first areas of focus as they are closest to Red Hill well.
Flushing will continue until testing confirms the drinking water is fit for consumption as determined by the Hawaii Department of Health. We remain committed to providing all necessary support to families and communities throughout the flushing process.
