| Sewage Warning | Schofield Barracks Sewage Discharge OAHU | Sewer Manhole Overflow | On Sunday, August 17, 2008, at 2:38 pm, CWB was notified by State Operator of a sewer manhole overflow at/near Bldg 137 (Noho Place). An estimated 480 gallons flowed from the manhole at about 11:30 am and about 150 to 200 gallons entered into a storm drain. CWB called Aqua Engineers (Contractor for Army) for verification and details. Aqua Engineers did not know if discharge entered into a stream. CWB told Aqua Engineers to find out if it did. CWB was notified by Aqua that they could not determine discharge site because they did not have map of drainage system but would have information for me on Monday. Monday has come and gone and CWB has not received any notification. CWB will follow up with appropriate actions with permitee.
As a precaution, the public and military personnel are advised to stay out of Waikoloa Gulch and Kaukonahua Stream. CWB does not believe discharge will reach Kaiaka Bay. However, a small amount may reach Kaukonahua Stream.

Contractor has been selected for repairs to force main. Contractor is awaiting parts from mainland. Anticipate repairs to begin Monday 8/11/08.
At the beginning of repairs, we anticipate a certain amount of sewage being spilled into the water. This is unavoidable due to the location of the pipe under the bridge and over the Kalihi Channel.

| Sewage Warning | Waste Water Discharge Sand Island Bridge | Broken Sewer Line | UPDATE 7/29/08. NAVFAC Hawaii (formerly PWC) in not involved in the repair of the Army's broken force main as previously stated. There was a miscommunication on the part of the CWB and we apologize to the Navy for any inconveniences.
A follow up investigation at 9 am by CWB Monitoring staff found the force main still discharging and no warning signs were found. Due to the height of the break and brisk winds, strong sewage odor and intermittent spray was noticed at wharf area fronting the Marine Education & Training Center. The odor persisted thru the Kalihi Channel side of Sand Island boat ramp. Since no warning signs were observed, CWB Monitoring staff posted signs at the Sand Island Boat ramp and the shoreline across the Kalihi Channel downwind of the Sand Island Bridge. Staff at the Marine Education & Training Center said they will keep people away from the wharf area.
After signs were posted, staff from the Army's Directorate of Public Works arrived and were briefed by CWB staff. Army Environmental staff were instructed to collect water samples at specific sites daily until bacteria levels return to normal. |
