Rainwater runoff from roofs and other hard surfaces can cause surface erosion, taking sediment and other pollutants into waterways. Harvesting rainwater reduces erosion by capturing the rain before it becomes runoff. It can then be slowly released into the environment, which reduces pollution and improves the health of waterways.
