WENATCHEE, Wash. -

A nest of snakes was discovered in a Wenatchee sewer pipe when a contractor ran a video camera down the line.

City Engineer Gary Owen told The Wenatchee World he thought there were a half-dozen snakes or more. It's hard to tell from the video, but Owen thinks they were bull snakes, possibly pets someone flushed down a toilet.

The snakes might have tried to exit the sewer through toilets, but Owen says the snakes were sealed off and entombed when a new liner was put in the sewer pipe.

The snakes were spotted May 15 in a recessed area of the pipe about 150 feet from a manhole. Owen says there was no way they could have been rescued.
