Open innovation firm InnoCentive is supporting global housing nonprofit Habitat for Humanity in a new Challenge to find low-cost solutions to harvest water and remove impurities so that water is suitable for human consumption.
Around 768 million people in the world do not have access to clean drinking water, and Mexico is one country that faces challenges in this area. Although more than a third of homes in Mexico suffer from water shortages, torrential rain does fall during certain months. However, without a proper management system, this water is unusable. Most rainwater is not fit for human consumption because of pollutants and microorganisms that cause severe illness when consumed.
