BENGALURU: Taunted by his brother for paying hefty bills and challenged by his wife to find a tech-solution for their water woes, a city-based software engineer has developed a WiFi-based smart water level controller and meter that allow tracking of real-time water availability in overhead tanks and underground sumps through smartphones. Chinnayya Math, 39, who has designed the device, said: “We’re addressing Bengalureans’ biggest problem: Knowing how much water is there in the tank and when to pump water into it.” He has simplified everything in such a way that the smartphone screen will serve as the dashboard for the water level in the tank. “You can virtually see the water tank of your house while sitting in office,” he said. The device will monitor the quality of water as it measures its Ph and TDS content, besides automatically switching on or off the pump depending on the threshold level in the tank like any other automatic water controller. His device is an improvisation of the flow meters that only track water consumption by different users. His smart device includes an electronic board with a WiFi chip, two intelligent sensors (one to be installed in the overhead tank and another in the sump) and an app to be downloaded on the phone. Math, a resident of Sarjapur Road, has tested the device at 50 locations, including a chain of paying guest accommodations, and the results have been positive. “It enhances accountability on the part of tanker water suppliers. Currently, there’s no mechanism to ascertain if the tanker is delivering 6,000 litres as agreed. But sensors in this meter will give the exact quantity supplied and avoids pilferage by tanker operators,” Math said, while pointing out that his device has won appreciation from NITI Aayog and Bangalore Chamber of Industry and Commerce. Math is all set to market his device—‘Ni-the water saviour’. Math’s tryst with smart meter started when he told his brother, who stays at Sindhagi in north Karnataka, that his family was dependent on tankers and ran an average monthly water bill of Rs 2,500. “My brother laughed at me; I was paying 10 times more than him. But it was my wife’s question that set me thinking.” Vaishali asked him as an engineer, why couldn’t he build a product that will save water. Math was joined by a friend who was out of job and the duo dived into the world of Internet of Things (IoT) and data analytics to come up with a prototype of the meter. The device was deployed in houses of four of their friends and the data related to water consumption was analysed and technical glitches were fixed. Saving each drop With the device constantly monitoring water consumption, it promotes awareness on conserving the scarce resource. “In my house, the average daily water usage reduced from 600 litres to 350 and the daily cost came down from Rs 85 to Rs 50,” he said. In January-February, his 15 friends contributed Rs 1 lakh each after realising the potential of his product. Math, who quit his job in a tech company, runs a startup, ‘Nimble Vision’ (www.nimblevision.in) along with his wife.
