UPDATED: Rescue Efforts Continue for Worker Sucked into Sewer System in Lawrence

UPDATE: 5:00 p.m.

A robotic camera from Hamilton Township is being moved into a sewer pipe on Baker's Basin Road to help search for the worker who was sucked into the pipe at 2:15 p.m. after he opened a manhole cover.

Lawrence Township Police Capt. Mark Boyd did not release the worker's name, but said the man was still in the pipe. The pipe empties into a sewer plant run by the Ewing-Lawrence Sewer Authority.

According to officials, the sewer pipe is 48 inches in diameter where the man was sucked in. It reduces to 24 inches and then to 19 inches and then 12 inches as it moves toward the sewer plant. There are also at least two bends, one of which is a 90-degree turn, officials said.

Rescuers from Lawrence, Trenton, West Windsor, Hamilton, the state  Park Police, NJ Water Authority and Ewing-Lawrence Sewage Authority are on scene.

The missing man's sister also is on scene talking with police and rescue workers on scene say the man's wife is en route.

Rescuers are attempting to search between a half-mile and one mile of pipe.

Boyd said it was unknown whether there were air pockets in the pipes that would allow the worker to breath.

Emergency workers used jet skis and boats to search the nearby Delaware and Raritan Canal as a precaution, before they knew that the drain was connect to the sewer system. They did not know if it was a storm drain that emptied into the canal.

More information will be provided as it becomes available.
