Hydrants are points tagged emergency=fire_hydrant; fire_hydrant:type is pillar, underground, wall or pipe.
The query
[out:json][timeout:60]; area["name"="Lausanne"]["admin_level"="8"]->.a; node["emergency"="fire_hydrant"](area.a); out;

Live result from overpass.ch, cached for up to 12 hours. Map data © OpenStreetMap contributors (ODbL).
How it works
- Coverage depends on the city. Some fire services import their hydrants, others leave it to volunteers.
Variations
- Underground hydrants only: add
["fire_hydrant:type"="underground"].
Run it from your code
curl https://api.overpass.ch/v1/YOUR_API_KEY/interpreter \
--data-urlencode 'data@query.overpassql'
import requests
query = open("query.overpassql").read()
r = requests.post("https://api.overpass.ch/v1/YOUR_API_KEY/interpreter",
data={"data": query}, timeout=120)
r.raise_for_status()
print(r.json()["elements"][:3])
const res = await fetch("https://api.overpass.ch/v1/YOUR_API_KEY/interpreter", {
method: "POST",
body: new URLSearchParams({ data: query }),
});
if (!res.ok) throw new Error(await res.text());
console.log(await res.json());
Save the query as query.overpassql. It works the same in Overpass Turbo, QGIS and JOSM.
