Hawai‘i County Department of Water Supply urges community to be drinking water prepared
Hawaiian Electric extended a public safety power shutoff watch through Nov. 13, and Hawai‘i County Department of Water Supply reminds customers that a public safety power shutoff or any prolonged power outage can result in lengthy water service disruption or outages.
The county Department of Water Supply relies on Hawaiian Electric power to operate its wells and booster pumps to distribute water.

A public safety power shutoff could result in power outages that could last hours to days, depending on weather conditions, location and possible damages. Water Supply customers and the community should be drinking water prepared.
Water preparation tips
- Determine household water needs: Each person should have a minimum of 1 gallon of water per day for at least 14 days. Prepare also for the water needs of pets and livestock.
- Store water safely: Use only clean, dedicated, food-grade containers. Wash containers thoroughly with dishwashing soap, sanitize using 1 teaspoon of mild liquid chlorine bleach per quart of water and then rinse thoroughly. Fill containers from the tap, leaving as little air as possible. Store in a cool, dark area. Water not commercially bottled should be replaced every 6 months.
- Treat drinking water: It might be necessary for Hawai‘i County Department of Water Supply to issue a boil water notice because of water quality problems. Customers will be notified about this via various communication channels. Instructions to treat water can be found online.
- Restrict water use: Restrict water use to essential uses only such as drinking, cooking and sanitation. No lawn watering, car/boating washing, etc.
- Stay informed: Sign up for Hawai‘i County Civil Defense alerts.
A public safety power shutoff watch means Hawaiian Electric enhanced its monitoring for areas at highest risk of wildfire. It does not mean power will be shut off, but rather that Hawaiian Electric could do so if needed to reduce the risk of a fire.
