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!
