BWS Asks for Water Conservation During Storm
News Release: Due to the impact of the Kona storm today, Friday, March 13, 2026, the Board of Water Supply (BWS) urges all residents to continue to conserve water and use it for essential purposes only – drinking, cooking, and hygiene. All residents, especially those without power, should keep water use to an absolute minimum and should not fill containers at this time. All BWS pumps need electricity to operate. During a power outage, the BWS will have limited ability to pump water out of its wells and other water sources and up to reservoirs. Until power can be restored, the water left in the reservoirs will be all that is available.
