Challenge

A water utility needed to monitor 25 pumping stations spread across 50km in rural areas. No cellular coverage, no power grid, and manual visits were costing $5000/month in fuel and labor. Pump failures went undetected for hours, causing service disruptions.

Solution

Deployed LINK485 Zero LoRa gateways with solar power to monitor:

  • VFD parameters (frequency, current, voltage)
  • Water level sensors
  • Flow meters
  • Pressure transmitters

Long-Range Network Design

Using LoRa's long-range capability with repeater topology:

  • Central gateway at control room with elevated antenna
  • Direct line-of-sight to pumps up to 15km away
  • 2 repeater nodes to reach distant pumps (30-50km)
  • All nodes solar-powered with battery backup

Results

  • ✓ Real-time monitoring of all 25 stations
  • ✓ Instant alerts for pump failures or anomalies
  • ✓ Reduced site visits by 80% (only for maintenance)
  • ✓ Pump efficiency improved by 22% through data analysis
  • ✓ Annual savings: $40,000 in operational costs

Technical Highlights

  • LoRa SF12 for maximum range
  • 10-minute data intervals (battery optimized)
  • Offline buffering for temporary connectivity loss
  • OTA firmware updates
