MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202611002046 A) filed by Chandigarh University, Mohali, Punjab, on Jan. 8, for 'solar operated water tank cleaning and purification system.'
Inventor(s) include Dr. Ravinder Tonk; and Abhishek Yadav.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a solar-powered water tank cleaning and purification system designed to address contamination issues in water storage structures, particularly in regions with limited access to clean water and sanitation facilities. The system incorporates an automated cleaning mechanism equipped with rotating brushes, spray nozzles, and sludge-removal components to eliminate algae, biofilm and accumulated sediments from the interior surfaces of the tank. Integrated with a multi-stage purification unit, the invention ensures effective treatment of stored water to meet safe consumption standards. The system is fully powered by solar energy, enabling reliable operation in off-grid and rural environments while reducing dependence on external electricity and manual labour. Smart sensor modules continuously monitor water quality parameters, such as turbidity and pH, and automatically activate the cleaning or purification cycle when preset thresholds are exceeded. The system is cost-effective, environmentally friendly and suitable for diverse applications."
