Full Notification

The Board of Water Supply (BWS) is actively working to repair the 24” water main which ruptured near the entrance to the Waimanalo Gulch Landfill on Farrington Hwy. above Ko Olina in Leeward Oahu.
 
The BWS was notified yesterday at 5:30 p.m. and crews identified the break in a 24" main just past the entrance to Waimanalo Gulch Landfill on the westbound shoulder of Farrington Hwy. This main feeds water to the entire Waianae Coast.
 
As of 9:30 a.m., BWS crews had exposed about 20 feet of pipe in an open trench. Additional safety equipment to shore up the sides of the trench was delivered to the site and installed. The shoring equipment and fresh BWS crew have resumed work to repair the main.
 
The heavy lift equipment used to install the shoring necessitated temporarily closing one lane of Farrington Hwy., westbound, while the installation was taking place. The same lane-closure may be required after the repair is finished to remove the shoring from the trench.
 
While the break is completely within the dirt shoulder of Farrington Hwy. just west of the Waimanalo Gulch Landfill driveway and will have minimal impact into the evening commute. Driver caution in the area will still be necessary. Both westbound lanes of traffic on Farrington Hwy. will remain open, except for short, occasional interruptions to move heavy equipment. Drivers are encouraged to slow down and watch for Police Officers on duty who may make traffic pattern adjustments, as necessary.
 
The Waianae-bound merge lane from the landfill road has been closed to keep vehicles away from the work area.
 
The main repair is expected to extend into the evening hours. BWS crews will try to minimize impacting traffic flow between the 2:00 p.m. to 7:00 p.m. peak commute hours.
 
There is reserve capacity in Waianae Coast reservoirs so that most Leeward Coast residents still have water, though water pressure may be lower than normal or may vary. All Leeward Coast residents are encouraged to conserve water, use what they need for necessary tasks such as cooking, cleaning, and personal hygiene, until the system has been returned to full operation.
 
A bypass was set up to partially restore water to the Honokai Hale subdivision, though water pressure there will be lower than normal, and may vary. Those residents are also being encouraged to conserve water, while using what they need for cooking, cleaning and personal hygiene, until repairs have been completed and the system returned to normal operation.
 
Currently there are 6 homes on Farrington Hwy. and the landfill which are without water. Water wagons have been provided for the affected customers.
 
We will continue provide occasional updates as to progress on the repair. #mainbreak #hitraffic (Please share this update.)
