With an aim to help monitor the growing exploitation of fresh water in the country, third year students of Amrita School of Engineering at Amrita University have developed an efficient method of testing water quality in large water bodies like lakes, ponds and dams. Smart Water, their prototype secured the top prize at the first-ever “iDeate – The Great Digital India Challenge” organised by Cisco.
Teams from IIT, Kharagpur and IIIT, Bangalore bagged the second and third prize respectively.
Surya Murugaian, the leader of the team says that as budding engineers, they wanted to invent something sustainable. So they formed a team “Circuit Breakers” and worked for more than a year to come up with Smart Water.
Dr. Sasangan Ramanathan, Dean, Amrita School of Engineering, Amrita University explained that their students proposed a novel technique to collect various parameters of water such as the pH level, dissolved oxygen, temperature, and conductivity only from a limited number of locations across a water body.
“The data collected is used to generate a hypothesis function through machine learning that can accurately predict the parameter values at all other locations. Our students have also framed a technique that can predict the quality state of a water body a month or even a year in advance, so that necessary measures can be taken to save them from over-exploitation,” he said. Students have tested the prototype in water bodies of all sizes, from swimming pools to lakes. Dr. Sasangan Ramanathan pointed out that numerous companies like Cisco had shown interest to take the prototype forward towards commercialisation. The Amrita Technology Business Incubator (TBI) is also in talks with their department.
