About 640,000 gallons of sewage spilled out of the Schofield Barracks Wastewater Treatment Plant between 6:30 p.m. Sunday and 6:30 a.m. yesterday morning, according to a news release from Aqua Engineers Inc.

The sewage went directly into an irrigation ditch on Dole property northwest of Lake Wilson and did not flow into either Lake Wilson or Kaukonahua Stream.

Signs warning of the spill were posted near the ditch, and samples from the spill were being tested to determine the extent of the contamination.

PARKING SUSPENDED ON WAIKIKI STREET

Parking along Kai'olu Street in Waikiki will not be available for the next few weeks, as contractors have resumed jet grouting as part of the Beachwalk Wastewater Emergency Bypass project.
