BRIEF ELECTRICAL DISRUPTION CAUSES DISCHARGE OF UNDISINFECTED TREATED WASTEWATER INTO LAKE WILSON

An electrical power flicker at the Wahiawa Wastewater Treatment Plant last night (July 30) resulted in a spill into Lake Wilson of 3,500 gallons of effluent that had undergone tertiary treatment, but not the final ultraviolet (UV) disinfection.  (Tertiary treatment is a high level of wastewater treatment.)

            The brief power disruption occurred at 11:52 p.m., knocking the UV equipment off-line for four minutes.  The system re-set itself and resumed normal functions once power was restored. 

            Warning signs are being posted, samples are being taken, and the State Department of Health has been notified.
