The Louisville-based non-profit that provides portable water purification systems for developing countries and disaster areas is changing its brand.EDGE Outreach is now called WaterStep.Founder Mark Hogg says the new name and logo better reflect the group's mission of providing clean drinking water where it’s needed around the world, and is a reference to a shoe-recycling program that generates some of its operating funds.Hogg says he hopes the rebranding will also raise the organization’s profile among the many other groups in need of donations."You know, it’s kind of like growing up from middle school to high school and realizing you’re in school with the big kids now. That’s what we did today is grow up into the big kids’ school," he said.The new name and logo were developed at no cost by the CurrentMarketing agency.Hogg says the WaterStep has grown to the point that he’s now looking for a larger space to house its Louisville headquarters.
