A New York Times bestselling book by children’s writer Linda Sue Park helped put a once small, but mighty nonprofit on the global map. Today, Water for South Sudan is a name known around the world. Its work to bring clean drinking water to villages throughout the African nation is changing lives for young people in South Sudan. It’s also helping to raise a new generation of leaders as students in classrooms around the world join the cause. Salva Dut, whose story was shared in Linda Sue Park’s book A Long Walk to Water is the founder of the nonprofit birthed in Rochester. He joined Need to Know’s Hélène Biandudi Hofer during a visit to the states this month to discuss exciting changes being made.
