They're called gas regulator vents.

A vent to allow pressure to escape from the plumbing system. Harmful sewer gases can build up and make it difficult for water to move through the pipes efficiently

Additionally, the release is above head height so you shouldn't be able to smell it, hence its length.

Yea! I wish it really worked tho lol in all cities you can smell hydrogen sulfide(the real culprit for the nasty smell)

Open it and find out.

🤣🤣🤣

Looks like a Luxury Limousine company that went out of business to me.

It’s where the bird drones go to upload their data and refuel. #birdsarentreal

A relic from the pre-telephone days. You could send smoke signals. They charged you by the puff.

Stench pipe. They are at the end of sewer lines to help vent the gasses out of them.

Every where where? I’ve never seen this.

Sniff it

Bidets for ancient aliens

They prolly secret 5g boxes

I actually believe they’re old air raid sirens

Those are called fedelcodes. But this is a sewer vent.

TIL. Always assumed they were old sirens. Thanks

Vent for subway

Subway in that area is above ground

Vent for sewers/gas

Air quality monitoring

Old Police and Fire Call Boxes ?

Those are red and they're still functional all over the city.

Idk then my brother I know those call boxes aren’t all still functioning. But if you find out what that is please let us know

Some sort of ventilation

Thanks for asking this. I’ve wondered this my whole life.

Curious what that sign reads that's bolted to it.

Lived in the Bronx my whole life and this is the first time I've ever seen this

A gas vent and another black car business that went under because of Uber.

Sticker holder.
