Kīlauea Road Water Shutdown Scheduled April 7 Near Lighthouse

Homes and businesses along the portion of Kīlauea Road between Kauapea Road and the Kīlauea Lighthouse will lose water service for eight hours on Tuesday, April 7, when the Kauaʻi Department of Water and contractor Hawai'i Pacific Trenchless Inc. perform planned system work from 9 a.m. to 5 p.m.

The affected corridor includes residences, short-term rentals, and businesses in one of the North Shore's most active visitor-facing stretches. DOW posted the service notice on March 31, giving the area seven days to prepare.

Before Tuesday morning, residents should fill containers with enough potable water to cover cooking, drinking, and hygiene for the full eight-hour window. DOW advises against running water-dependent appliances during the shutdown and warns that water heaters prone to draining should be monitored once pressure drops. Anyone with medical or special water needs should contact DOW directly before the April 7 cutoff.

The work is assigned to Hawai'i Pacific Trenchless Inc., a contractor that specializes in rehabilitating or replacing pipes without cutting open road surfaces. That technique limits road damage but still requires isolating the main line and suspending service to customers while the work is completed.

DOW has posted a map of the affected section on its website; the department routinely deploys portable water stations during similar outages, though none has been confirmed for this service area. The outage is weather-dependent, and DOW's notice does not specify a rescheduled date if conditions on April 7 are unfavorable.

Planned shutdowns are part of the county's strategy to rehabilitate aging infrastructure before unplanned failures force multi-day outages across the same system. In a North Shore corridor where short-term rentals and tourism keep daily water demand consistently high, the eight-hour maintenance window represents a tradeoff the county is willing to make to avoid a far longer emergency repair.
