Reclaimed or recycled water is the process of converting water into water that can be reused for other purposes. Reuse may include irrigation of gardens and agricultural fields or replenishing surface water and groundwater. Reused water may also be directed toward fulfilling certain needs in residences and businesses and could even be treated to reach drinking water standards.
Reclaiming water for reuse applications instead of using freshwater supplies can be a water-saving measure. When used, water is eventually discarded back into natural water sources and can have extreme benefits to the landscape.
Waste water reuse is a long-established practice used for irrigation, especially in arid countries. Reusing waste water as part of a sustainable water-management allows water to remain as an alternative water source for human activities and can reduce the demand on groundwater and other natural water bodies.
