How can stormwater management influence groundwater recharge?

Proper stormwater management plays a crucial role in enhancing groundwater recharge by promoting the infiltration of water into the ground while simultaneously reducing surface runoff. When stormwater is effectively managed, techniques such as the use of permeable surfaces, green roofs, retention basins, and infiltration trenches can be implemented. These methods allow rainwater to percolate through the soil, replenishing the groundwater aquifers.

This process of infiltration is essential because it allows stormwater to contribute to the groundwater supply rather than contributing to surface water runoff, which can lead to flooding, erosion, and water quality issues. Enhanced infiltration through managed stormwater systems can significantly increase the volume of water that enters the groundwater system. Thus, effective stormwater management not only addresses immediate concerns such as flooding but also supports sustainable groundwater resources, which are vital for ecosystems and human use.
