Auto Industry Help Reduce Water Consumption With Innovative Solutions

The automobile industry is a key sponsor of any country's GDP, and offering sustainability-driven solutions is crucial, especially during difficult times. It is imperative for automakers to offer holistic, and sustainable solutions in all aspects, right from the time an idea for a new product is conceptualised till the product is out for public use. Water plays an important role here as more than 40,000 gallons of water goes into producing a single vehicle, and hence, the industry actively engages in various conservation practices to balance it out. In India, major automakers, as well as top ancillary units have switched to waterless solutions, reused processed water, and restrained usage of water for various applications.

These plants have also spread awareness among village communities and recharged more than they consumed in the entire year through scientifically designed groundwater recharge structures within and outside the plant premises. Projects were undertaken throughout the year to reduce fresh-water abstraction by maximising recycling and minimising leakages.
