How to report a running fire hydrant in NYC
Last updated: 2026-09-14
An open or leaking hydrant is a DEP water issue. File a 311 Fire Hydrant / Running Hydrant complaint with the exact location. Uncapped flow can waste roughly 1,000 gallons per minute and cut pressure for homes and FDNY. Use this page to draft paste-ready text — we prepare the text. You file it on 311. Nothing goes to 311 unless you send it.

What you can report on a hydrant
311’s Fire Hydrant Complaint covers hydrants that leak a little, run without full blast, or run at full blast; damaged, leaning, knocked-over, or missing hydrants; missing valve-box covers; misuse without a permit; and damaged fender posts. Pick the option that matches what you see.
- Running / open: Priority for DEP shutoff — say whether it is a trickle or full blast.
- Damaged hardware: Cracked barrel, missing parts, or a missing street valve cover near the hydrant.
- Misuse: Someone using hydrant water without a permit — report the activity and location; do not confront.
Spray caps, permits, and safety
Opening a hydrant requires a permit for any use of the water. During heat waves, DEP and FDNY promote free spray caps (for adults 18+) from firehouses so kids can cool off without dumping a thousand gallons a minute into the gutter. An illegally opened hydrant can bring fines of up to $1,000 and/or up to 30 days imprisonment per DEP notices — another reason to report through 311 instead of handling the valve yourself.
Stay out of the stream. High-pressure flow can knock a person down. If the open hydrant is creating an immediate life-safety emergency, call 911; otherwise use 311.
How to photograph and describe the scene
- Location first. House number, corner, or identifiable storefront.
- Show the flow. A still that makes the water visible helps DEP triage.
- Say leak vs full blast. 311 offers separate choices — match your words to the photo.

- Discolored water at the tap: Often follows open hydrants; DEP advises running the tap until clear and cold, and reporting pressure or quality issues through 311 when they persist.

Frequently asked questions
Who handles a running fire hydrant in NYC?
The Department of Environmental Protection (DEP) responds to leaking, running, or full-blast hydrant complaints filed through 311. Use the Fire Hydrant / Running Hydrant request type in the 311 app or portal, or call 311 with the exact location.
Why does an open hydrant matter?
An open hydrant without a proper spray cap can waste on the order of 1,000 gallons per minute, drop water pressure for nearby buildings and firefighting, and stir sediment that causes discolored tap water. Report it promptly so DEP can shut it down.
Are spray caps legal?
Adults 18 and over can request a free spray cap at local firehouses. Opening a hydrant without a permit or the right hardware can bring a fine of up to $1,000, imprisonment of up to 30 days, or both, per DEP public notices. Do not open a hydrant yourself to “fix” it.
What if a car is blocking the hydrant instead?
That is a parking violation (within 15 feet of a hydrant), not a running-hydrant water complaint. Use Illegal Parking / our fire-hydrant blocker guide. You can file both if the hydrant is open and a vehicle is also blocking access.
