How does reducing stormwater runoff save energy?

Stormwater runoff is a significantly growing source of pollution to our streams and rivers and is a large contributor to local flooding events. In urban areas, energy is required to purify drinking water, maintain or update infrastructure used to control and treat runoff, and repair damages caused by flooding.


Also, allowing water to infiltrate into the ground instead of running offsite helps replenish groundwater storage. This reduces the energy needed to import water in dryer times.
