An 88-year-old man on Long Island was rescued by cops after he fell into a collapsed cesspool while doing yard work.

Ralph Santos was at his North Bay Shore home in Suffolk County when he plunged into the sinkhole that formed as he was weed whacking, police said.

The senior grabbed a hold of the weed whacker’s electrical cord to keep his head above the waste as he waited for help, cops said.

Santos was eventually spotted by his wife, who called 911 at about 5:25 p.m., police said.

Officers responded within minutes, tossing Santos a life ring and pulling him out to safety as the sinkhole continued to expand.

Santos was taken to Southside Hospital with non-life-threatening injuries.
