WAILUA – Treated and disinfected effluent from the Wailua wastewater treatment plant overflowed Tuesday morning from an onsite manhole and made its way to an area just outside the fence line of the plant at Lydgate Beach Park near the county’s park maintenance building.
County officials estimate that approximately 10,000 gallons of treated and disinfected effluent was spilled.
The spill occurred sometime after 8 a.m. and was contained by approximately 8:50 a.m.
The cause of the spill is under investigation. Preliminary results indicate there is partial blockage of the sewer line leading to the ocean outfall or partial blockage of the ocean outfall.
Plant personnel have posted sewage spill signs and disinfected the area. The spill did not extend to the ocean or other bodies of water, nor did it reach the Lydgate Beach Park pavilion or Kamalani Playground.
State Department of Health officials have been notified.
