The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an automatic rain-activated manhole cover opening and closing system intended to improve urban drainage efficiency during heavy rainfall. The system operates using a rainwater collection unit that accumulates rainwater and increases in weight, thereby actuating a mechanical linkage connected to a manhole cover. As rainfall continues, the increased load causes the manhole cover to open automatically, allowing faster discharge of stormwater and reducing waterlogging on roads. [0042]When the rainfall stops, the collected water gradually drains out through outlet openings, reducing the weight and enabling the system to automatically return the manhole cover to its closed position. The invention functions without the use of electrical power, sensors, or manual intervention, making it reliable during power failures and extreme weather conditions. The system enhances public safety, minimizes accident risks, and provides a simple, cost-effective solution for urban stormwater management."
