Manage Hydrants

This guide walks you through managing hydrant records, configuring your brigade’s response area, and syncing hydrants from external sources.

Prerequisites

• Brigade admin or organisation admin role
• Access to your brigade’s StationOne instance
• For sync: ArcGIS credentials and response area coordinates

Steps

1. Define Brigade Response Area

Before syncing hydrants, define your brigade’s jurisdictional area:

1. Navigate to Settings → Unit Settings
2. Scroll to Response Area section
3. Click Define Response Area
4. Use the map drawing tool to:
   • Click points around your brigade’s boundary
   • Connect points to form a polygon
   • Close the polygon by clicking the first point
5. Review the polygon boundaries
6. Click Save Response Area

The response area is stored as GeoJSON and used to filter hydrants during sync.

Tips:

• Be as accurate as possible with boundaries
• Include all areas your brigade responds to
• Exclude areas outside your jurisdiction
• You can redraw if needed

2. Sync Hydrants from ArcGIS

Automatically import hydrants from external data sources:

1. Navigate to Hydrants from the main menu
2. Click Sync Hydrants button
3. System connects to ArcGIS API
4. Hydrants within response area are imported
5. Review sync results:
   • New hydrants created
   • Existing hydrants updated
   • Duplicates flagged for review

What Gets Synced:

• Unique external ID
• GPS coordinates (latitude/longitude)
• Metadata from ArcGIS
• Last synced timestamp

Duplicate Prevention:

• Checks external ID first
• Proximity check (within 10m)
• Manual review for potential duplicates

3. Create Hydrant Manually

Add individual hydrants not in ArcGIS:

1. Navigate to Hydrants from the main menu
2. Click New Hydrant button
3. Enter hydrant details:
   • Unique ID: Internal identifier
   • Latitude: GPS latitude coordinate
   • Longitude: GPS longitude coordinate
   • External ID: Optional ArcGIS reference
4. Click Create Hydrant

When to Create Manually:

• New hydrants not yet in ArcGIS
• Private property hydrants
• Temporary hydrants
• Testing or training purposes

4. Edit Hydrant Details

Update hydrant information:

1. Navigate to Hydrants
2. Click on hydrant from list or map
3. Click Edit button
4. Update fields:
   • Unique ID
   • GPS coordinates
   • External ID
5. Click Update Hydrant

Note: Synced hydrants may be overwritten on next sync if coordinates don’t match ArcGIS data.

5. Delete Hydrant

Remove hydrants from the system:

1. Navigate to Hydrants
2. Click on hydrant
3. Click Delete button
4. Confirm deletion

Warning: Deleting a hydrant also deletes all inspection history. Consider marking as inactive instead if supported.

Next Steps

After managing hydrants, you may want to:

Create Hydrant Runs

Organize hydrants into inspection routes (see Inspect Hydrants)

Enable Public Hydrant Display

Show hydrants on Station Portal:

1. Navigate to Settings → Public Access
2. Toggle Public Hydrants Enabled
3. Save settings
4. Hydrants appear on Station Portal map

View Hydrants on Map

See all hydrants geographically:

1. Navigate to Hydrants
2. Click Map View tab
3. Zoom and pan to explore
4. Click markers for hydrant details
5. Filter by inspection status if needed

Search and Filter Hydrants

Find specific hydrants:

1. Navigate to Hydrants
2. Use search box for unique ID
3. Use filters:
   • Overdue - Past due for inspection
   • Due Soon - Approaching inspection deadline
   • Up to Date - Recently inspected
4. Results update automatically

Clear Response Area

Remove response area definition:

1. Navigate to Settings → Unit Settings
2. Scroll to Response Area section
3. Click Clear Response Area
4. Confirm action
5. Response area and sync data removed

Note: This also clears last sync timestamp.

Tips

Drawing Response Areas

Accuracy Matters:

• Use satellite view for precision
• Follow road boundaries where applicable
• Include all relevant areas
• Zoom in for detailed boundaries

Complex Areas:

• Can only create single polygon (no holes)
• Multiple disconnected areas not supported
• Contact support for complex jurisdictions

Syncing Best Practices

Initial Sync:

• Review all imported hydrants
• Check for duplicates
• Verify GPS accuracy
• Update any incorrect data manually

Regular Syncs:

• Schedule periodic syncs (monthly/quarterly)
• Review new hydrants added
• Check for coordinate updates
• Investigate any duplicates

After Sync:

• Create or update hydrant runs
• Schedule inspections for new hydrants
• Update overdue inspection targets

Managing Duplicates

If sync flags potential duplicates:

1. Review hydrants in question
2. Check GPS coordinates (within 10m?)
3. Compare external IDs
4. Delete true duplicates manually
5. Keep both if actually different hydrants

GPS Coordinate Tips

Finding Coordinates:

• Use Google Maps (right-click → coordinates)
• Use GPS device on-site
• Import from ArcGIS automatically
• Mobile app may support GPS capture

Format:

• Latitude: -90 to 90 (negative = south)
• Longitude: -180 to 180 (negative = west)
• Decimal format (not degrees/minutes)
• Example: -37.8136, 144.9631

Common Issues

Response Area Not Saving

If response area won’t save:

1. Verify polygon is properly closed
2. Check you clicked first point to close
3. Ensure at least 3 points in polygon
4. Try redrawing with fewer points
5. Check browser console for errors

Sync Not Finding Hydrants

If sync returns no hydrants:

1. Verify response area is defined
2. Check ArcGIS credentials are configured
3. Confirm hydrants exist in ArcGIS for your area
4. Review response area boundaries
5. Check sync logs for errors

Duplicate Hydrants Appearing

If you see duplicate hydrants:

1. Check if external IDs match
2. Measure distance between hydrants
3. Review sync history
4. Delete duplicates manually
5. Consider adjusting proximity threshold

Cannot Edit Synced Hydrant

If edits are being reverted:

1. Synced hydrants may be overwritten
2. Make changes in source ArcGIS system
3. Re-sync to pull updated data
4. Or stop syncing and manage manually

GPS Coordinates Wrong

If coordinates appear incorrect:

1. Verify latitude/longitude order
2. Check for negative signs (hemisphere)
3. Ensure decimal format (not DMS)
4. Compare with map visualization
5. Update manually or re-sync
