Board of Water Supply crews just completed repairing the waterline and are in the process of attempting to restore water service.

The water main broke about 1:30 a.m. today near 84-680 Kili Drive in Makaha Valley, police said. If everything goes well, water service should be restored by midnight, said Tracy Burgo, a Board of Water Supply spokeswoman.

Customers on the lower floors of the Makaha Valley Towers have water service now, but other residents can obtain water from a water wagon on site.

Traffic still is being diverted onto Ala Mahiku Street and Makaha Valley Road.

The 16-inch water main broke beneath a section of the road between Ala Mahiku Street and Huipu Drive, causing a huge sinkhole, Burgo said.

Kili Drive, between Farrington Highway and Huipu Drive, is closed to traffic, Burgo said.
