Manholes are critical elements of urban infrastructure, widely utilized by Municipal Corporations' Storm Water Drain and Sewerage Departments, as well as utility providers like Telecom, Internet, Piped Gas, and Power Distribution Companies. With 30,000 to 80,000 manholes in most cities or districts, open manholes caused by theft or negligence remain a global safety concern. These hazards have led to countless accidents involving vehicles, pedestrians, and animals, often resulting in severe injuries or fatalities. Existing smart systems with SIM-based alerts are expensive and fail to provide immediate warnings to nearby pedestrians or vehicles, which is crucial for preventing accidents.

Our patented "Open Manhole Alert & Accident Prevention System" offers an innovative and cost-eective solution to this pressg issue. The system instantly activates when a manhole is opened, deploying a 3.5-foot pop-up pipe with a powerful flashing red LED and reflective stripes to warn nearby pedestrians and vehicles. The flashing LED operates for up to 48 hours, ensuring visibility even in waterlogged conditions where open manholes are especially dangerous. A prominently displayed phone number on the pipe allows the public or authorities to notify the manhole owner promptly. This reusable and resettable system is designed for reliability, operating without power for the pop-up action. Even in the event of battery failure, the reflective stripes continue to provide eective warnings. Economical and easy to implement, this patented system is a game-changer for urban safety, capable of saving lives and preventing accidents on a large scale.
