Engineering for Change

Interest: Water

Nearly 1 billion people don’t have access to clean water, and the consequences are fatal. Diarrhea is one of the leading killers of children under the age of five. Fortunately, the solutions needed to access clean water can be affordable and reliable. With informed design and management, drawing water, transporting and purifying it are all possible for everyone worldwide.
