Board of Water Supply crews have finished repairs to a 24-inch water main break near the entrance to the Waimanalo Gulch Landfill on Farrington Highway above Ko Olina in leeward Oahu.

As of 4 p.m. today, crews began to backfill the trench up to the level of the main. If no leaks develop, crews will move to fully charge the system. However, it could take several hours before full water pressure and flow are returned, which is expected to happen later this evening.

BWS said it was notified of the rupture at 5:30 p.m. Tuesday. One lane of Farrington Highway westbound was closed during repairs this morning due to the heavy lift equipment required.

Both westbound lanes of traffic on Farrington Highway are now open, except for short, occasional interruptions for the movement of heavy equipment.

Most leeward residents should still have water through reserves, but the water pressure may be lower than normal or may vary. The BWS encourages all leeward coast residents to conserve water until the system has been returned to full operation. Residents of the Honokai Hale subdivision are also encouraged to conserve water.

Six homes on Farrington Highway and the landfill are currently without water and have been provided with water wagons.
