# Epic Cleantec

> Epic Cleantec is a San Francisco cleantech company that builds onsite water reuse systems for buildings, letting towers and campuses recycle up to 95% of their own wastewater into clean non-potable water, recovered heat energy, and organic soil products. Its OneWater platform installs treatment in the basement so showers, sinks, and laundry water get reused on site instead of flushed to a distant plant. The company got famous for turning recycled building water into commercial beer, and it counts high-rise developers as its core customers.
