Epic Cleantech
Epic CleanTec is redefining urban sanitation by decentralizing wastewater treatment into individual buildings. Epic’s patented on-site treatment system converts wastewater solids into a high quality organic soil, all within a single building. The separated water, with the solids now removed, can be purified and reused for flushing, irrigation, and other non-potable uses.

Our proprietary approach has been recognized by many leading organizations, including the Bill and Melinda Gates Foundation, the Cleantech Forum, and the Environmental Protection Agency.
