The impact of Hurricane Lowell has been significant, and we hope you and your loved ones are safe. During this large-scale recovery effort, our focus is to ensure we provide our communities with safe drinking water and get our systems operational as quickly and as safely as we can.
Our crews are working around to the clock with limited staff support and resources to address the various emergency water infrastructure needs resulting from extensive storm damage and large-scale power outages across the island. Our office remains closed for business through Friday, September 11, 2026. However, should you need to contact us to report any outages, breaks, or other DOW service emergencies, please contact our dispatch line at (808) 245-5400 Option 1, Monday-Friday (excluding holidays) between the hours of 7:45 a.m. and 4:30 p.m. For after-hours reporting, please contact KPD non-emergency dispatch at (808) 755-8516 or (808) 652-7837.
