Hydrants & Water Sources
Track every hydrant and water source in your district: location, owner, main size, flow tests with the NFPA 291 flow class, maintenance history and in/out-of-service status — shown on a colour-coded map and available to the apps and dispatch.
Feature flag: Records.Prevention.Hydrants. Menu: Records → Hydrants.
The hydrant list and map
The header shows N hydrants, N out of service, N due for a flow test. The Map colours each hydrant by flow class (black = out of service). Filter, search by number or address, or open one for details.
Adding hydrants
New hydrant or Import hydrants (CSV with a header row: number, latitude, longitude, type, address, main_size, flow_gpm, owner — existing numbers are updated).
| Field | Notes |
|---|---|
| Hydrant # | Your identifier; unique per department. |
| Type | Dry barrel, wet barrel, standpipe, draft site, tank, cistern … |
| Address / Coordinates / Point of interest | Position; can be linked to a map POI. |
| Owner / Owner name | Municipal, private, utility. |
| Main size (in) | Water main diameter. |
| Flow (gpm), Static / Residual (psi) | The last known values. Recording a flow test updates them automatically. |
Flow tests and maintenance
On the details page:
- Record flow test — enter static pressure, residual pressure, pitot pressure and outlet diameter. Flow is computed as
29.83 × c × d² × √pitot, rounded to 10 gpm, and the NFPA 291 class (AA / A / B / C) is set from it. - Record maintenance — date, kind (flush, paint, repair, replace cap …) and note.
- Take out of service / Return to service — with a reason; out-of-service hydrants are black on every map and flagged to crews.
Analytics reports hydrants tested in the last 12 months, in service and by flow class.
Setup examples
| Department | Notes |
|---|---|
| Municipal fire | Import from the water utility's GIS export; schedule annual flow tests by district; use Owner to distinguish private hydrants. |
| Rural / wildland | Add draft sites, cisterns and tanks as water sources with their capacity in the notes; flow tests optional. |
| Industrial site | Plant hydrants and monitors keyed to the site grid; maintenance log for the fire-water system. |
