High Water Detection Systems
Improve Public Safety On Flooded Roadways
High Water Detection Systems (HWDS) by High Sierra Electronics are the state-of-the-art in public safety for warning the public to stay out of flooded roadways. A well-designed flooded road detection system not only improves public safety but can also help a region conserve Emergency Management, Rescue and Road Department resources, and help in the overall response to flooding events.
Advance warning stations advise motorists of a weather-impaired or flooded roadway by activating flashing beacons, message signs, or automatic road barrier gates.

Automatically activate beacons and barrier gates
Road and Public Works Departments often manually deploy barriers and warning signs when roadways flood. But, with no way to know a street is flooded without driving out to the site, lengthy delays occur which put lives and property at risk. High Water Detection Systems at problematic sites provide agencies with the opportunity to deter or prevent motorists from entering flooded areas, potentially saving lives and property.
Conditions are monitored 24×7 by software that can issue alarms to key personnel, and feed information to a public or intra-agency website.
where used
Heavy or sustained rainfall events can result in rapidly rising water and flash flooding with little or no warning. Some typical problem sites include:
- Low water crossings
- Underpasses
- Areas prone to coastal flooding
- Urban areas where drains exceed their capacity
Benefits of High Water Detection Systems
- Detect and monitor real-time rainfall and rising water conditions around the clock
- Activate flashing beacons and warning message signs
- Stop vehicles driving through flood with automatic road barrier gates
- Send automatic alerts and detailed notifications to key personnel and emergency responders
- Publicly display real-time road hazard and closure data on the web
