Find fire hydrants in Hawaii
Hydrant Finder displays mapped fire hydrant locations in Hawaii using
OpenStreetMap data served
from AllFirefighter's local hydrant database. It's a free, browser-based tool designed for pre-incident planning,
first-due area familiarization, and water supply training exercises.
🗄️ Local OSM database
Searches for Hawaii use AllFirefighter's local OpenStreetMap hydrant database.
The current production snapshot contains
2,535,703 mapped hydrants worldwide.
Database refreshed:
September 12, 2026.
This is a global database count, not a Hawaii hydrant total.
Local coverage depends on what has been mapped in OpenStreetMap and should not be treated as an official municipal hydrant inventory.
🚒 4 fire departments in Hawaii
Hawaii's hydrant infrastructure varies significantly by island and community. Honolulu has dense urban coverage maintained by the Board of Water Supply; rural Big Island communities near active lava zones may have limited or no hydrant systems. Salt water intrusion and volcanic terrain create unique challenges for water supply planning.

How to use Hydrant Finder
Getting started takes under 30 seconds. Enter an address in the search box or click My location
to center the map on your GPS position. Choose a search radius (500 m–1 km for dense urban areas; try 2–5 km for
rural coverage). Click Search area — hydrants appear as markers on the map and as a sorted list
on the right, nearest first. Click any result to open it on the map, or use Get Directions to open Google
Maps navigation directly to that hydrant.
How firefighters use this tool
📋Pre-incident planning
Identify primary and secondary hydrants around target hazards before arrival. Document long-lay distances and alternative supply points.
🗺️First-due familiarization
Understand hydrant spacing and coverage density throughout your first-due area. Identify dead-end mains and low-flow zones.
⚠️Coverage gap analysis
Spot zones where tanker shuttle, relay pumping, or drafting from static sources may be the primary water supply strategy.
🎓Training exercises
Use real hydrant data for water supply scenarios, pump operator drills, and fireground pre-plan development.
Tips for better results
No results or very few? Increase the radius to 2–5 km. Rural and semi-rural areas have lower OSM mapping density — hydrants exist but may not yet be mapped.
Confirm in the field. OSM data is community-contributed. Not every hydrant is mapped, and mapped locations may have slight coordinate offsets. Always verify on-scene.
Supplement with flow data. Pair Hydrant Finder with the Hydrant Flow Calculator to estimate available GPM from pitot pressure readings.
Mobile GPS. The "My location" button performs best on mobile devices with GPS enabled and location permissions granted to the browser.
Contribute missing hydrants. If your area has hydrants that don't appear, consider adding them to OpenStreetMap — it improves coverage for every first responder who uses OSM-based tools.
Frequently asked questions
Click My location to center the map on your GPS position, choose a radius, and click Search area. You can also search any address using the address box. Results appear on the map and in the sidebar, sorted by distance.
Hydrant locations come from OpenStreetMap (OSM). Searches are served primarily from AllFirefighter's local OSM hydrant database. Overpass remains available as a fallback if the local database cannot serve a request. Coverage depends on community mapping and may be incomplete.
Sparse results usually mean the area isn't yet fully mapped in OSM — not that hydrants don't exist there. Try increasing the radius or zooming out. You can also contribute missing hydrants to improve coverage for everyone.
Hydrant Finder is a planning and familiarization aid. It is not a substitute for verified fire department records, ISO water supply surveys, or in-field confirmation. Always verify hydrant location, accessibility, and operability before and during incident operations.
Yes. The address search uses Nominatim (OSM geocoding). Type any address, intersection, or landmark. Autocomplete suggestions appear as you type — select one to jump the map to that location and automatically search for nearby hydrants.
Each result includes a Google Maps directions link. For bulk hydrant data, OSM exports are available via openstreetmap.org/export. A CSV export feature may be added in a future release.
Yes — the tool works globally across 35+ countries. Use the country selector to navigate. Coverage is strongest in North America, Western Europe, and Australia. Coverage elsewhere depends on local OSM community activity.
AllFirefighter maintains a local OpenStreetMap hydrant database and refreshes the production dataset on a scheduled basis. The latest successful refresh date is shown on this page. OpenStreetMap remains the underlying source, with Overpass available as a fallback service.
According to NFIRS data, Hawaii has approximately 4 fire departments, including career, combination, and volunteer companies. Use this map to explore hydrant coverage across the state.
Hydrant spacing in Hawaii is governed by local water utility standards and the applicable fire code. Most jurisdictions reference NFPA 291 as a baseline, but actual spacing varies between urban, suburban, and rural areas. Always verify against your district's most recent ISO PPC water supply data.
