Anahola Landslide Damages Aliomanu Road, Water Service Restored

A landslide sent a boulder crashing into Aliomanu Road in Anahola on Wednesday, striking a water mainline and forcing the Kauai Department of Water to shut off service to the surrounding neighborhood for nearly three hours while crews scrambled to make repairs.

The department announced the emergency water service shutdown at 12:30 p.m. on March 11, 2026, after the boulder fell and struck the mainline. The outage extended beyond Aliomanu Road itself, cutting water to Kukuna Road and all branching roads in the area, possibly including Kalalea View Drive, though the department has not confirmed whether that street was definitively affected.

By 3:15 p.m., the department announced that water service had been restored. The turnaround, just under three hours from shutdown to restoration, came as crews worked simultaneously on both the damaged mainline and the road surface.

Road repairs on Aliomanu Road remain ongoing. A partial one-lane closure with alternating traffic is in effect while crews finish the work, and drivers passing through the area are advised to proceed with caution. No injuries were reported in connection with the landslide or the boulder strike.

Whether recent weather contributed to the slope failure has not been confirmed. Kauai was under a Flash Flood Warning and a Flood Watch at the time of the incident, conditions that can destabilize hillsides, though no official source has explicitly linked the two.
