Hurricane Season Preparedness: 10 Steps to Prevent SCADA Network Interruptions

Hurricane season presents significant challenges for critical infrastructure sectors like Water/Wastewater, Oil & Gas, and Power Utilities. Maintaining continuous telemetry during extreme weather requires strategic preparations, electrical isolation, and redundant wireless communications.

10 Best Practices for Network Resilience

• 1 Conduct a Comprehensive Risk Assessment: Evaluate vulnerable physical assets including exposed antenna towers, low-lying substations, and critical remote terminal units (RTUs).
• 2 Deploy Industrial Wireless Modems: Traditional wired telephone lines and copper cables often break during flooding or high winds. Weatherized wireless modems ensure reliable links when wired lines fail.
• 3 Establish Redundant Paths: Dual-band or hybrid topologies ensure data automatically reroutes if a primary tower or frequency experiences interference.
• 4 Leverage Cloud SCADA Monitoring: Secure remote data logging allows field engineers to monitor water levels, line pressure, and power distribution from off-site emergency centers.
• 5 Ensure Backup Power (UPS & Generators): Modems and telemetry nodes must remain powered during grid blackouts to maintain continuous data flow.
• 6 Pre-Position Emergency Deployment Kits: Keep pre-configured backup modems, directional antennas, and power supplies ready for rapid field replacement.
• 7 Collaborate with Regional Utilities: Establish mutual-aid hardware agreements and emergency contact protocols with neighboring municipalities.
• 8 Conduct Pre-Storm System Drills: Test secondary failover systems and battery backup runtime before severe weather hits.
• 9 Perform Physical Inspections & Install Surge Protection: Inspect antenna guy-wires, check line-of-sight clearance, and install heavy-duty inline lightning arrestors to protect sensitive radio electronics.
• 10 Establish a Phased Post-Storm Recovery Plan: Prioritize restoring telemetry to life-safety infrastructure first, such as main water lift stations and sub-station breakers.
