Erode district, characterized by its dry climate and erratic water supply, faced significant challenges in meeting the water needs of its rural population. With a demand of 74 million litres per day, the district’s supply was inconsistent, leading to water scarcity and high electricity bills due to inefficient management of Overhead Tanks (OHTs). IAS officer Raja Gopal Sunkara, leveraging his dual degrees from IIT Kharagpur and experience in urban water management, identified IoT as a solution to these challenges.
Smart sensors bring real-time control to villages
Upon his appointment as District Collector in May 2023, Sunkara initiated the installation of IoT devices in 50 habitations across 16 villages. These devices automate water management by providing real-time updates on water levels, automating pump operations, and preventing overflow. This system not only reduced electricity bills by approximately 40% but also increased water supply by over 20%, demonstrating a significant improvement in resource management.
Troubleshooting in the field builds a smarter system
The implementation of IoT technology was not without challenges. Initial technical glitches, such as voltage fluctuations damaging controllers, were addressed by introducing solar power supplies with battery backups. Continuous monitoring and collaboration with tech experts were essential to ensure the system’s compatibility with existing infrastructure. Training for local representatives and maintenance staff was also crucial for the system’s success.
The IoT initiative has had a profound impact on the residents of Erode. In Ponmudi village, for example, electricity consumption decreased by 50%, and water supply increased by 44,180 litres per day. This not only reduced the financial burden on local bodies but also alleviated the time burden on women, who traditionally spent long hours waiting for water. The initiative has improved water availability, reliability, and pressure, enhancing the quality of life for rural residents.
Supporting India’s vision for smart, self-reliant villages

This initiative aligns with India’s broader goals of sustainable development and self-reliance, as outlined in the Atmanirbhar Bharat and Viksit Bharat missions. By utilizing local resources and funds, such as the village panchayat general fund and the 15th Central Finance Commission funds, the project exemplifies a scalable model for other regions facing similar challenges.
Looking ahead, the plan is to expand the IoT system to more villages, utilizing existing funds and resources. This initiative not only addresses immediate water management challenges but also sets a precedent for innovative, technology-driven solutions in rural India. By harnessing IoT, Erode district is paving the way for a more sustainable and efficient future, making it a national gamechanger in rural water management.
