Sewage spill reported in Wailua, Waimea

WAILUA – County officials are notifying the public of a wastewater spill Tuesday morning at 9:20 a.m. from the Wailua Wastewater Treatment Plant (WWTP). The wastewater spill flowed into Lydgate Park and has been contained. Lydgate Park in the area of Kamalani Playground is closed to the public. Signs have been posted to inform the public to stay out of the affected area.

The spill is a result of heavy rainfall in the area. Officials estimate that approximately 52,000 gallons of wastewater spilled from the Wailua WWTP over a 30-minute period. The spill was contained at approximately 9:50 a.m.

The spill did not discharge into the ocean or other bodies of water.

In Waimea, county officials reported Tuesday a wastewater spill from several manholes on Waimea Road between Panako Road and Alawai Road and on Alawai Road in the vicinity of the Waimea Road intersection.

Officials reported that wastewater spill was cleaned up, the area was disinfected and signs were posted to inform the public.

The Waimea Wastewater Treatment Plant had a spill as well, overflowing into an irrigation ditch next to the facility.

The irrigation ditch is part of the ditch system that connects to Kikiaola Small Boat Harbor. County officials coordinated with contractors to open the ditch to relieve flooding in the area. Signs were posted to inform the public to stay out of the affected area.

The spill is a result of heavy rainfall in the area, causing storm water to enter the sewer system (inflow and infiltration (I/I)) and overwhelm the Waimea WWTP. Officials estimate that over 100,000 gallons of secondary treated wastewater spilled from the Waimea WWTP.

State Department of Health officials have been notified.

    It rains here, we must find a way to keep sewage facility from spilling during wet weather. Last time we had a spill from this facility a year or 2 ago, they were squirting it into the Wailua River.

    So on this one, the spill might not have reached the river yet but it has to go somewhere or will they leave sit at the Lydgate playground and disperse it with chemicals?

    How irresponsible that the Kauai government chose to build a children’s beach-park and playground directly alongside a sewage treatment plant. And one that is highly unstable and prone to spills and leaks. I will never understand that.
