Clean Water Starts with Clean Highways

About the Campaign

At Caltrans, we are dedicated to keeping our highways and waterways clean.  The goal of Caltrans’ Protect Every Drop campaign is to educate Californians about the sources and pathways of stormwater pollution and to change behaviors of the public to reduce stormwater pollution in and around the state highway system. Our water is precious- so it's important to Protect Every Drop.

Did you Know?

Stormwater from California's freeways and highways flow directly to local bodies of water. Stormwater runoff results from water from rain, melted snow, and water from sprinklers and hoses that runs on the ground's surface and ends up in storm drains. Eventually the water in the storm drains can makes its way to our lakes, rivers, streams, and the ocean. As the stormwater runoff moves along the surface making its way into storm drains, the water collects trash, debris, oil and other pollutants.
