As of 2017, there were 785 million people around the world who didn't have access to clean water. Researchers at the Massachusetts Institute of Technology have made a portable device that can remove salt from water. The device uses solar energy to create an electric field that pushes away charged particles like salt, bacteria, and viruses. It can purify water anywhere, at any time.

India’s rapidly increasing population in cities has made it tougher to manage precious resources like water. The problem ranges from poor management of water contamination and leakages in the distribution network.
Cities are home to 36% of India’s population but account for 70% of water pollution (Central Pollution Control Board). Groundwater levels in India declined by over 60% between 2007 and 2017 (The Print). Due to the scarcity of water, treated sewage has become an alternative source of water. Absolute Water brings a low-cost technology to convert raw sewage into drinking water. The sewage treatment plant (STP) uses a vermi-filtration process to convert sewage water into potable water. The recovered water meets WHO standards and can be used for drinking and household purpose.
Cities can adopt such eco-friendly methods to recover water for various purposes because when you think about it wouldn’t we want to live in cities with better access to water?
