Water Reuse and Recycling
About Water Reuse
Water reuse is the practice of reclaiming water from a variety of sources, treating it, and reusing it for beneficial purposes. It can provide alternative supplies for potable and non-potable uses to enhance water security, sustainability, and resilience. The EPA’s Water Reuse Program helps foster collaboration among water reuse stakeholders and helps advance water reuse applications across the United States. Sign up for the EPA's water reuse email updates to learn about the latest activities and find opportunities to get engaged.
