Wastewater Discharge in Puhi Bay in Hilo
A discharge of Secondary Treated and Disinfected Wastewater occurred on Monday, June 5, 2017, along the shoreline in the vicinity of the Pua Sewage Pump Station and the Pacific Aquaculture & Coastal Resource Center in Puhi Bay in Hilo.
The cause of the discharge is currently under investigation.
Recently, 14 joints in the vicinity of shoreline had been repaired, individually tested and dye tested to verify that the leaks had been repaired.
Yesterday’s discharge was discovered during a dye test of the ocean outfall a week later to ensure previously identified leaks on the offshore piping had been satisfactorily repaired.
The shoreline area has been posted with warning signs is as indicated in the map above.
The Wastewater Division is performing testing of shoreline waters in the vicinity of the discharge in order to verify that bacteria levels are within acceptable regulatory limits.
Shoreline testing will continue until authorization to remove the signs is obtained from the State of Hawai‘i Department of Health.
