An environmentally friendly way to warn about rising water
Solar Lighting International has created an innovative and environmentally friendly solution for monitoring and warning about potential flood hazards. Solar-powered warning systems use solar panels to convert sunlight into electricity, which then powers sensors, radio transmitters, and warning flashing beacon systems. Sensors are placed strategically at bridge foundations, river banks, creek beds, and other flood-prone areas to detect rising water levels and send a signal that activates our advanced warning systems.
The flood warning system can also alert a central monitoring system, which in turn activates warning sirens, alarms, and other warning devices. As global weather grows less predictable, high water and flood warning systems are becoming a more prevalent requirement for roads and bridges.

When the water rises, the warning is already flashing, powered entirely by the sun.
Flood detection that never sleeps
Why Solar High Water Warning
Reliable warning,
with no grid
to fail.
Because the system is self-sustaining, there are no ongoing electricity costs and no chance of the power failing: a redundant, reliable, cost-effective solution for remote or off-grid locations where public safety is paramount.
Easy to install, low maintenance
Relatively easy to install and requiring very little maintenance. Solar panels and battery systems are built to withstand high winds, heavy rain, ice storms, and snowfall, so they keep working in the most challenging long-term environments.
Self-sustaining & off-grid
No ongoing electricity costs and no chance of the power failing. The self-sustaining design makes it a redundant, reliable, cost-effective solution for remote or off-grid locations.
Instant, accurate detection
Sensors detect rising water levels instantly and with a high degree of accuracy, activating the warning poles the moment a flood begins. Critical for flash-flood-prone areas, where reducing pedestrian and driver risk is the main goal.
Flexible, customizable design
Sensors and radio activation can send repeater-like signals down a river faster than the rising water, vital for dam releases. Every system can be tailored to the unique characteristics of each river, stream, or water body.
Engineered features that keep the warning on.
Every high water system is designed to activate the moment it matters, then run unattended in the field, powered only by the sun.

Who relies on SLI flood warning systems
Solar high water and flood warning systems are cost-effective, environmentally friendly, reliable, and flexible: a smart choice for organizations protecting communities from flooding and fast-rising water. They can also be integrated with traditional flood warning systems, such as gauges and meteorological data, for maximum accuracy and reliability. The initial cost may be higher, but the long-term life-saving benefits far outweigh it.
