Stormwater harvesting is primarily used to collect and store rainwater runoff for non-potable purposes, helping reduce reliance on traditional water sources. Common uses include irrigation for landscapes, parks, and agriculture, as well as toilet flushing, car washing, and industrial processes that do not require drinking-quality water. In some cases, harvested stormwater is also used for groundwater recharge or stored in detention basins to help manage flood risks.
By capturing stormwater before it becomes runoff, communities can reduce the strain on stormwater infrastructure, decrease pollution entering natural waterways, and make more efficient use of rainfall, especially in urban environments. While not typically used for drinking without proper treatment, stormwater harvesting plays a significant role in supporting water conservation and sustainability efforts.
