What’s New Version 2.15.2
Download map areas and use maps and water sources completely offline.
Edits made without signal are uploaded automatically once you are back online.
Relay pump calculation follows fire-service doctrine, with configurable hose length and diameter.
The supply line follows roads and terrain and shows the number of hoses between pumps.
Nearby water sources are ranked by route distance instead of straight-line distance.
Description
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.
FIND WATER SOURCES NEARBY
- 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

- Pipe diameter, pressure, flow rate
- Couplings (type, diameters)
