Nagpur, an industrial city of 2.4 million in the eastern part of the Indian state of Maharashtra, lacks water, despite being located on the Nag river. The river is polluted, and even the monsoons do little to secure supplies. Together with Mahagenco, a government-owned energy company, the city is now developing new ways to provide sufficient water for a new thermal power plant. For the first time in India, a new five-hectare sewage plant will draw 130 million liters of contaminated water from the Nag each day and treat it exclusively for use in the power plant as cooling and service water. Endress+Hauser supplied the entire measurement technology, nearly 100 instruments for level, flow, pressure and temperature measurement as well as liquid analysis. “We are the only provider in the country that offers a complete instrumentation portfolio in combination with extensive expertise in the area of water and wastewater,” says Sunil Bhor, Head of Industry Water & Wastewater from Endress+Hauser India. The treated water will cool three, 660-megawatt thermal power plant units, thus saving 47 million cubic meters of fresh water per year.
