Epic Cleantec ("Epic") is a full-service water reuse firm based in San Francisco, CA. We provide turnkey water treatment and reuse systems for customers, creating a one-stop-shop for design, engineering, permitting, construction support, and ongoing operations. Our team has decades of experience across the wastewater and built environment value chain, with expertise in wastewater treatment and solids handling technology, project financing, policy, and operations. Epic deploys onsite water treatment and reuse systems into individual buildings or groups of buildings, converting building wastewater into treated water for non-potable applications, natural soil amendments, and recovered wastewater heat energy. The Epic system can help a project reduce its water demand by up to 95%, which saves owners hundreds of thousands of dollars annually on their water and sewer bills. Born out of initial work with the Bill and Melinda Gates Foundation's "Reinvent the Toilet Challenge," Epic reduces the cost and complexity of onsite wastewater treatment and reuse, lowering costs for building owners, easing strain on municipal utilities, and strengthening sustainability and resiliency efforts. Epic has been featured widely in prominent publications (The New York Times, FastCompany, Inc. Magazine, NBC Bay Area, TechCrunch) and was most recently named a Fast Company 2021 World Changing Ideas Award honoree in two categories - Urban Design and Spaces, Places, and Cities.
