## What is FireYak?

FireYak helps fire departments quickly find the nearest usable water source — fire hydrants, suction points, water tanks, fire water ponds and fire stations on an interactive map.

All data comes from the community-driven project OpenStreetMap.

- Displays fire hydrants, suction points, water tanks, fire water ponds and fire stations near you
- GPS-based location: see the nearest water sources at a glance
- Distance display in meters and kilometers
- Estimated number of supply hoses

- Pipe diameter, pressure, flow rate
- Couplings (type, diameters)
- Water source (main, pond, stream, river, lake, tank, well)
- Capacity, reference number, operator, address
- Coordinates and OSM ID

EDIT WATER SOURCES
