There's lots of non-potable purposes that stormwater can be used for, typically with the goal of conserving drinking water and reducing strin on water infrastructure. Common uses include landscape irrigation, where stormwater provides a sustainable source for watering lawns, gardens, and parks. It is also frequently used in industrial processes such as cooling or washing, where high-quality potable water isn’t necessary. In urban settings, stormwater can supply water for flushing toilets, cleaning streets, or even firefighting reserves.
In agricultural areas, it may be used for crop irrigation or livestock watering, depending on the quality of the collected water and local regulations. Some systems are designed to recharge groundwater by allowing treated stormwater to percolate into aquifers, helping to replenish natural water supplies. With proper treatment, stormwater can be made suitable for a broader range of applications, though it is rarely used for drinking without advanced purification.
