Kauai County workers are responding to a sewage spill in Kapaia that was apparently caused by a blocked sewer line.
The spill was reported at around 8 a.m. Tuesday 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 and flowed down the hillside below the bridge and into Kapaia stream.
The total volume of the spill is estimated at over 18,000 gallons, according to the Dept. of Health’s Clean Water Branch.
County sewer maintenance crews have been successful in at least partially clearing the blocked line, officials said. Overflow abated by 10:30 a.m. and the water level in the manhole was dropping.
Authorities have partially closed the mauka lane of Kuhio Hwy. 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.
The public is also advised to stay clear of the Kapaia stream and Hanamaulu Bay.
Warning signs are being posted and water samples are being collected, officials said.
