15-13...Sewer Force Main Break at Joint Base Pearl Harbor-Hickam

08/24/15 12:00 AM

Rls 15-13 ... Navy personnel responded to a call at 12 p.m. regarding an 18” wastewater force main that ruptured near Porter Avenue and 17th Street on the Hickam-side of Joint Base Pearl Harbor-Hickam (JBPHH). Crews were immediately dispatched and completed an emergency excavation to install a bypass line which stopped the spill at 4 p.m. 

Cause for the break is unknown at this time. Higher than normal amounts of rain water due to storm and flooding conditions throughout the island of Oahu are believed to have contributed to the situation. 

Assessment of the break and repairs are underway.

A portion of the wastewater from the rupture was contained on land and recovered with vacuum trucks. Approximately 24,000 gallons of sewage spilled with an estimate of 12,000 gallons entering an area storm drain that leads to a canal and discharges to a location east of Hickam Beach. 

The Navy has made all necessary notifications to the State Department of Health (DOH) as required by the wastewater treatment system’s operating permit. As required by DOH, signs will be posted near and around the exit of the storm drain canal and at Hickam Beach. Receiving water monitoring will be done by Navy personnel as required.

This public notification is an administrative requirement of the National Pollutant Discharge Elimination System (NPDES) permit issued to the NAVFAC Hawaii, Wastewater Treatment facility.
