A quiet celebration in Ranchi marks a historic milestone on India's journey towards ecological justice and water security. After six years of intensive research and basic experiments, TAP@app – a smart water monitoring system, which was designed by the local innovator Saket Kumar and his colleagues from the Indian Institute of Technology Kharagpur, has officially secured a patent.
VAS Bros Enterprises PVT LTD (VBEPL) registered according to Kumar's startup and faces the disposal of rural India water, waste and sustainability.

TAP@app is more than just one device. It represents the intersection of real -time monitoring, intuitive design and basic ability. The system is based on a Mod bus platform and contains proprietary sensors that combine titration and imaging techniques as well as IoT and AI functions. A 4G/5G communication module combines water sources at the village level with cloud-based servers and offers real-time water quality diagnostics and forecast warnings.
However, the true influence lies in the human element. Through the Waterbank Foundation Trust, TAP@app vbbepl becomes a vehicle for behavior changes and decentralized resilience. His flagship program Barterwater for sustainability, which debuted at the UN Water Conference in New York, redesigned the access of the water as a participatory ecosystem. Village dwellers earn rainbow loans for environmentally friendly tasks, such as These credits can be replaced for up to 1,000 liters of clean drinking water per household and for bamboo -based products.
The first use of the model was brought to the market on February 16, 2025 in the village of Pakri, Dumaria Panchayat (Ara, Bihar)-a region, which is historically affected by arsen-contamed groundwater. The cleaning system uses the OAS technology, an indigenous method incubated in IIT charger and is used with the treated Laterit to filter arsenic and other toxins. OAS is performed among the top 100 innovations of India and is now set in the Lohardagga Industrial Area for Mass Production with Agriculture of the Jharkhand Industrial Area Development Authority (Jiada).
This innovative ecosystem attracts attention both in Germany and internationally. The initiative is supported by Paniit USA, Wheels Global Foundation, Win Foundation and Husk Power Systems and also works with the National Bambus Mission and the Ministry of Development of the Northeast Development to establish bamboo processing units. Through vocational training programs as part of the Green Skills initiatives of the National Skill Development Corporation, local young people, especially women, receive practical training and position them as managers in this green economy.
The program has already started the most important political decision -makers. Both NITI AAYOG and the office of the main consultant of the main consultant have the initiative for his focus on the 17 goals for sustainable development, the 29 functional domains of Panchayati Raj Governance and Waterbank for eight important water. What distinguishes this program is the unique ability to merge the latest technology with the dignity of basic participation and to transform every act of sustainability into concrete rewards and every drop of clean water into a common performance.
Saket Kumar, CEO of VBEPL and President of Waterbank, summarizes the vision briefly: “Barterwater is not just about technology, participation and future-proof rural India against the climate crisis.”
In a world that deals with environmental uncertainties, this local innovation of Jharkhand offers more than just hope-a reproducible model presents in which sustainability is not imposed, but is put together and where the future rivers fall from scratch.
