A Penngrove horse fell into a septic tank early Monday, landing precariously with its back legs six feet down in the muck.
Owners of the horse, kept at an Elysian Avenue ranch, called for help at about 3:30 a.m. The four-year-old horse had fallen while standing on ground over the tank, which collapsed.
Rancho Adobe firefighters found themselves faced with an unusual rescue, said Jimmy Bernal, Rancho Adobe acting fire captain.
"(Its) back legs were inside the septic tank, which was about six-feet deep. The front legs were out of the hole," said Bernal.
Firefighters brainstormed the best rescue method available at that hour.
