HONOLULU -- Officials posted signs warning of a sewage spill are being posted along the Pearl Harbor bike path and at Middle Loch.

About 109,000 gallons of untreated wastewater spilled Tuesday from a major sewer pipe that was ruptured by a Hawaiian Dredging construction crew, city officials said.

The contractor was doing emergency work on a 42-inch broken force main when it accidentally severed the backup 30-inch line. The break is near the 14th hole at the Ted Makalena Golf Course in Waipahu.

City officials said it dispatched 10 trucks, which were able to vacuum all but 12,000 gallons of the raw sewage, which got into a drainage canal.
