Water Main Break Causes Sinkhole, Cuts Water to Nine Homes

A water main break on Nov. 21 produced a sinkhole at about 12:30 p.m. on South Kalaheo Avenue near Kaapuni Drive, officials reported, shutting down all lanes and leaving nine homes without water. Crews from county and utility crews responded to assess damage and begin emergency repairs, and authorities advised motorists to seek alternate routes while public safety and repair efforts were underway.

Traffic through the affected stretch was disrupted for hours as work crews stabilized the site and completed temporary repairs. Hawaii News Now provided on scene updates and photos documenting the response. Officials said repair work was in progress and that residents impacted by the service interruption would be notified when water service was restored. Additional updates were expected after crews completed stabilization and temporary fixes.

The event highlighted the immediate impacts of infrastructure failures on daily life in Kauai County. For affected households, loss of municipal water service can interfere with basic needs and preparations for the holidays, and nearby commuters faced longer travel times during the midday disruption. For emergency responders and utility crews, the incident required rapid coordination to secure the roadway, protect motorists and pedestrians, and restore a critical service.

Local officials did not indicate a timeline for full restoration of the roadway or permanent repairs as of the Nov. 21 updates, which were posted at 2:03 p.m. HST and updated at 4:00 p.m. HST. Residents and motorists were urged to follow official notices and to expect follow up information from county agencies once crews completed temporary work and assessed longer term repairs.

The sinkhole and water outage serve as a reminder of the vulnerability of island infrastructure to sudden failures and the importance of preparedness and clear public communication. County crews will continue their work to return water service and reopen the roadway, and further announcements will provide details on restoration and any needed road repairs.
