It’s a s–t storm on the Lower East Side.

Someone has been hurling dirty diapers from a window of a public housing complex on Essex Street — and disgusted neighbors want the crappy caretaker to cut it out.

Dozens of nasty nappies have piled up on an awning above the first-floor of the 23-story Seward Park Extension building at 64-66 Essex. Others have hit the sidewalk.

“You hear ‘splat’ and then you get the brown plague,” griped a construction worker on a job across from the Broome Street side of the building, the scene of the foul fusillade. “It’s like aerial bombs.”

A Post reporter counted 22 diaper droppings on the awning Wednesday.

The putrid pelting has been going on for at least a year, locals say. But no one has caught the stealth soiler in the act.

Peeved pedestrian Rita Rivera, 56, worries that it’s only a matter of time before she gets peppered with poop as she passes the housing complex on her way to work.

“I always see full diapers,” she said. “It’s so disgusting … I walk quickly.” she said.

Brooke Myers, 56, a neighborhood resident for 20 years, said she avoids Broome Street altogether “because it’s so filthy.”

One resident couldn’t believe a turd tosser lived in his building.

“I’m embarrassed,” he said.

Carmen Orta, president of the Seward Park Extension Tenant Association, said the building manager “is going to send a letter to everyone who has a baby.”

The New York City Housing Authority claims it’s on the case, saying the agency’s hired someone to clean the awning because of “safety precautions.”

“We’ve already mailed residents and posted flyers throughout this development reinforcing proper garbage disposal methods and will continue to work to keep all canopies clean and clear,” said a NYCHA spokeswoman.

“They have incinerators on every floor,” huffed the hardhat. “ It takes a special type of person to throw s–t out the window.”
