Hawaii Kai water pipeline interrupts service, congests site visitors, closes Hanauma Bay and the Koko Head Capturing Complicated


Officials with the Board of Water Supply said crews are still working to repair a broken 24-inch water line on 5952 Kalanianaole Highway in Kuliouou, and the repairs are expected to last well into the night.

The disruption has restricted or severely reduced water supplies to much of eastern Oahu, from Kuliouou-Kalani Iki to the Kalama Valley.

Two westbound lanes will remain closed between Moomuku Place and East Halemaumau Street, but an opposite lane has been opened to westbound traffic. Drivers are advised to expect delays by Monday.

BWS said it had watercars and tenons positioned in the area, including:

>> A water truck parked in the driveway on 6030 Kalanianaole Highway

>> And spigots to fire hydrants at 5914, 6030, 6044 Kalanianaole Highway

Residents can request a roving water truck by calling 748-5000 extension 1, but BWS officials said, “Due to the overwhelming number of calls and requests for roving water trucks, customers are encouraged to go to one of the water pumps to refuel.”

Customers in the region are urged to save water only for essential uses – cooking, drinking and personal hygiene.


Oahu residents from Kuliouou to Koko Head on Hawaii Kai today can expect low water pressure – or no water at all – as Board of Water Supply crews work to repair a 24-inch aqueduct on 5952 Kalanianaole Highway in Kuliouou that broke overnight.

The repair work is causing a lot of traffic on the motorway lanes close to the city.

The 24-inch transmission line moves large volumes of water to east Honolulu, BWS said, and staff are making adjustments to provide water to customers outside of the immediate work area where traffic delays are likely.

After noon, officials said customers in Lower Hawaii Kai and Kalama Valley should see water service slowly returning, but those in the Kamehame Ridge and Portlock areas will remain without water.

However, a Kalama Valley resident told the Honolulu Star Advertiser that the water supply was still down at 5:00 p.m., and a BWS representative told the resident that the outage for parts of the valley would likely continue until Monday.

BWS officials said roving watercars have been dispatched to water failure areas and customers can call 748-5000 ext. 1. However, callers to this number have to wait a long time to reach an agent.

The water line disruption has also closed the Hanauma Bay Nature Preserve and Koko Head Shooting Complex, the Honolulu Department of Parks and Recreation announced this morning.

DPR added that the disruption could also affect water supplies to other city park locations in Hawaii Kai.

Customers in the affected areas are encouraged to conserve water and use only essentials such as cooking, drinking and personal hygiene.

Two Ewa-bound left-hand lanes of Kalanianaole will remain closed between Moomuku Place and East Halemaumau Street for the duration of the repairs, which are expected to continue until Monday.
