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 #ProtectEveryDrop. Take the Pledge!

    Your actions today directly impact the water we drink, swim in and eat fish from.

    During a drought, pollution becomes even more concentrated because of lower water levels in all bodies of water.

    Debris you see on the roadways often ends up in streams, lakes, rivers and the ocean.
