With water scarcity becoming increasingly prevalent around the globe, an article written by Paul Hond of Columbia Magazine dials in on the importance of water reuse solutions. Hond highlights water scarcity, aging infrastructure, excessive use of potable water, and new technology created by Columbia University researchers. Overall, Hond’s article emphasizes the need for innovation and guiding principles toward water reuse, and is intent on communicating that society will exhaust the world’s most precious, finite resource without water reclamation.
During an interview between Hond and Kartik Chandran, an associate professor of earth and environmental engineering at Columbia University, Chandran stated, “we are treating all our incoming water to drinking-water quality. This makes no sense. Using potable water for everything – for irrigating crops, for flushing the toilet, for washing your car – takes more energy, more chemicals, more space. It’s needless.”
Chandran and his team at Columbia University understand the global need for water reclamation and reuse. As part of an Environmental Protection Agency center, the team has been researching bacteria to reduce energy demand for wastewater treatment called anaerobic ammonia oxidation (anammox). The process will reduce the amount of energy needed to treat wastewater by 25-60%; eliminating “nearly all CO2 emissions,” and helping to provide improved water reclamation solutions. 
In addition to the Columbia University’s research, Hond explores water challenges faced all over the country – from Central Valley, California to Boston, Massachusetts. Hond educates the audience that reusing wastewater is a necessity to sustain Earth’s most precious resource. “This is not a conversation about water alone anymore,” says Chandran to Hond, “This is about water sustainability.”
