Stormwater harvesting can be used for groundwater recharge by directing collected runoff into the ground through infiltration systems such as recharge wells, infiltration basins, or permeable surfaces. This process allows water to slowly percolate into underground aquifers, helping to replenish groundwater levels that may be declining due to overuse or drought. Before infiltration, stormwater is typically filtered to remove sediment, debris, and pollutants to prevent contamination of groundwater resources.
The effectiveness of groundwater recharge depends on soil type, site conditions, and the design of the recharge system. In regions where water scarcity is a concern, using harvested stormwater for recharge helps to restore natural hydrological cycles and supports long-term water sustainability. This practice also reduces surface runoff, which can help prevent flooding and improve the health of nearby streams and rivers.
