In a remarkable technological breakthrough, computer science students from Pranveer Singh Institute of Technology (PSIT), Kanpur, have designed a smart water bottle that could revolutionise access to clean drinking water, particularly in remote and rural areas. Developed with a focus on providing safe drinking water during travel, trekking, and in underserved communities, this innovation holds the potential to transform lives.

The self-purifying water bottle, unveiled during the Protech Innovation Challenge 2025 at PSIT, uses advanced UV-C sterilisation and a multi-layered filtration system to purify contaminated water within minutes. It is especially beneficial for people who rely on water from ponds, wells, and other untreated sources.

This smart bottle is equipped with Bluetooth connectivity, allowing users to operate and monitor it via a mobile device, thereby enhancing user convenience. The bottle features a 1.3-litre capacity and includes an 11.5 cm by 3 cm detachable filtration chamber. A smart cap embedded with UV-C LED lights and an electronic control system initiates purification as soon as the lid is closed.

The purification process begins with a steel sieve that filters large particles. The water then passes through activated carbon to remove odor, chlorine, and chemical impurities, followed by filtration through a polypropylene membrane. Finally, the UV-C LED light neutralises microorganisms by disrupting their DNA and RNA within 60 to 90 seconds. A rechargeable battery powers the entire system. The prototype was developed at a cost of Rs 790.

The innovation was developed by a team of five female students — Team Leader Poorva Tripathi and members Richa Agnihotri, Priyanshi Singh, Rishveen Kaur, and Rashika Jadoun.

PSIT Group Director Dr Manmohan Shukla praised the students, stating, "This innovation by our girl students aligns with the vision of a self-reliant India. Efforts are underway to further enhance the product and make it commercially available."

PSIT Chairman Pranveer Singh expressed pride in the achievement, saying, “Our daughters are not only excelling in technology but also addressing real societal needs. This is true innovation — the kind that brings meaningful change.”

This project stands as a testament to the ingenuity and social consciousness of young Indian innovators, and it signals a promising step forward in ensuring access to safe drinking water for all.
