Stormwater harvesting positively influences water quality downstream by reducing the volume and pollutants in stormwater runoff. By capturing and treating rainwater before it enters waterways, harvesting systems prevent the immediate discharge of contaminants.
The practice also helps mitigate erosion and sedimentation, further enhancing the health of aquatic environments. By acting as a natural filter, stormwater harvesting contributes to a more sustainable and ecologically balanced water cycle, positively affecting the quality of water in downstream rivers, streams, and other bodies of water.
