16-05...Sewer Force Main Break at Joint Base Pearl Harbor-Hickam

06/30/16 12:00 AM

Navy personnel responded to a call at 8:30 a.m. regarding an 18 inch wastewater force main that ruptured June 30 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 11:30 a.m.

Cause for the break is unknown at this time. Assessment of the break and repairs are underway.

Approximately 27,000 gallons of sewage spilled and entered a nearby storm drain. It is estimated that 20,000 gallons of sewage was recovered from the storm drain by vacuum truck which was on-scene within 30 minutes. The storm drain leads to a canal and discharges at a location east of Hickam Beach, approximately 2.5 miles away from the entry point when measured along the storm drain and canal path.

The Navy has made all necessary notifications to the State Department of Health (DOH) as required by the wastewater treatment system’s operating permit. Navy environmental personnel have inspected the affected areas. At DOH direction, and as a measure of precaution, the Navy has posted signs near and around the exit of the storm drain canal and at Hickam Beach. The Navy will also conduct water monitoring to determine near shore water quality impacts.

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