The public is advised to stay out of the waters of Nuuanu Stream between River Street and Honolulu Harbor and the waters of the harbor near the mouth of Nuuanu Stream, according to the Department of Health.
The Clean Water Branch was notified of a wastewater discharge from 1220 Aala Street due to a pipe clogged with rags and grease.
An estimated 4,350 gallons of wastewater entered into a nearby storm drain which emptied into Nuuanu Stream at River Street. The flow has been stopped and water sampling and posting of warning signs will be performed Friday morning.
The public is advised to remain out of these waters until warning signs have been removed.
