Regulations governing stormwater reuse vary by region, but they are generally designed to ensure the safe collection, treatment, and use of stormwater. In the United States, stormwater reuse is subject to guidelines set by federal agencies like the Environmental Protection Agency (EPA), as well as state and local authorities. These regulations focus on water quality standards, the design and maintenance of systems, and the intended use of harvested water.
For instance, stormwater used for non-potable purposes like irrigation or cooling often requires filtration and disinfection to remove contaminants. Specific treatment methods may be mandated based on the water's intended application, such as ultraviolet (UV) disinfection for irrigation systems. Local regulations may also cover the installation of backflow preventers to protect the public water supply. Some states and municipalities have adopted specific stormwater reuse codes that align with best management practices for water conservation, while others may provide incentives for implementing systems that meet sustainability goals.
