This corn snake was discovered in a sewer in the town of Gwynedd, North West Wales.
The 4-foot long reptile was found as workers performing maintenance at the facility, removed a manhole and discovered the snake.
"We took the cover off the manhole and saw this 'pink thing'," Welsh Water maintenance engineer, Keith Bridge told the BBC.
"I looked closer and realized that it was a snake. While I didn't know if it was poisonous or not, I knew that it wasn't from this country.
"This was the last thing I expected to see in the sewer and I was worried that it would get hurt if we didn't remove it."

How To Choose And Care For A Corn Snake
Workers at the facility contacted The Royal Society for the Prevention of Cruelty to Animals, which sent RSPCA inspector Andrew Broadbent to the facility.
"I arrived at the scene to find the adult Carolina corn snake perched on a metal assembly a few inches above the raw sewage flowing into the works,” Broadbent told the BBC. “With the assistance of staff, I was able to reach down and retrieve the snake," he said.
"This is another timely reminder as to some of the challenges faced by caring for exotic pets, such as snakes. It is vital accommodation is appropriate and secure," Broadbent said.
Broadbent speculates that the snake either escaped down a toilet or had been flushed. He is hoping that anyone who knows where the snake came from or knows who lost the snake will contact the RSPCA.
