Stormwater runoff carries pollutants such as fertilizers, oil, animal waste, and dirt to local streams, lakes, and ponds and may contribute to flooding during heavy rainfall events, putting added stress on the receiving bodies of water and their ecosystems. Excess discharge impacts streams by causing erosion, destroying habitat, and deforming natural channel flow. Utilizing storage devices such as cisterns or rain barrels will minimize stormwater volume leaving your property. Contaminants discharged to streams can cause illness, impair ecological health, and increase water treatment costs.
