LIHUE, KAUAI (HawaiiNewsNow) - County workers continue to respond to a sewage spill in Kapaia that was apparently caused by a blocked sewer line.
The spill was reported at around 8:00 a.m. this morning by a member of the public, when it was observed that a manhole was overflowing on the east side of Kapaia Bridge. Officials estimate that, when they arrived, approximately 100 gallons per minute was spilling into a drainage swale on the mauka side of the highway, then flowing down the hillside below the bridge and into the Kapaia stream.
County sewer maintenance equipment is on-site, and crews have been successful in at least partially clearing the blocked line. As of approximately 10:30 a.m., overflow had been abated, and the water level in the manhole was dropping.
Partial closure of the mauka lane of Kūhiō highway is necessary to allow for the equipment access for the work. The public is advised to drive with caution and observe all signs and directions in this area while the work is underway.
According to the Department of Health, an estimated 18,000 gallons of untreated sewage has spilled into Hanamaulu Stream. Warning signs are posted and water samples are being collected. The public is advised to stay out of Hanamaulu Stream and Hanamaulu Bay.
