ENV CREWS RECOVERED WASTEWATER SPILLS AT KAILUA RWWTP
July 24, 2009 --- Crews from the City’s Department of Environmental Services contained and recovered wastewater overflows this morning at the Kailua Regional Wastewater Treatment Plant.
The cause of the overflows was a bar screen at the plant that clogged because of mechanical failure.
The overflows lasted 10 minutes (10:23-10:33 a.m.) and five minutes (11:22-11:27 a.m.). The total volume was 41,460 gallons of untreated wastewater that entered a manmade drainage ditch where it was contained and did not reach receiving waters. ENV dispatched two Vactor and two cesspool trucks that recovered all of the wastewater from the drainage canal, which was redistributed back into the plant for processing.
ENV notified the state Department of Health who waived water sampling. ENV posted signs in the affected area.
Service has resumed at Kailua Regional WWTP, which is a secondary treatment facility that processes approximately 12 million gallons of wastewater daily.
