Caltrain Storm Water Program


Governor Jerry Brown declared in April 2017 the California draught over but asked Californians to make water conservation a way of life.  Caltrain agrees and makes sustainability efforts toward this goal. 

To further protect precious natural resources, Caltrain has also implemented a number of practices to reduce the flow of pollutants through its Storm Water Management Program, including:

  • Convenient, single-stream trash collection facilities on trains and in stations
  • Reoccurring trash and debris pickups along the rail corridor
  • Storm drain inlet marking to raise awareness of the storm drain system
  • Green landscaping that can filter storm water pollution before it reaches the storm sewer
  • Storm water pollution awareness and prevention education for employees and Caltrain riders

Storm water is more important than we often realize. When rain falls on our cities, it often picks up pollutants on its way to the storm drain system and eventually San Francisco Bay and the Ocean. Unlike our toilet, sink, and shower water storm water doesn’t go through a treatment plant, so pollutants may not be removed before the water reaches the Bay. Those storm water pollutants impact our natural areas, wildlife, and ultimately us.

Every effort counts and together we are making a difference. Find out more about projects that help reduce storm water pollution and explore other ways that you can help by visiting the Caltrain Storm Water Program webpage.

We hope to get your feedback! Please take a short survey located on our webpage.

About Caltrain: Owned and operated by the Peninsula Corridor Joint Powers Board, Caltrain provides commuter rail service from San Francisco to San Jose, with limited commute service to Gilroy. Caltrain has enjoyed five years of consecutive monthly ridership increases, surpassing more than 60,000 average weekday riders earlier this year. While the Joint Powers Board assumed operating responsibilities for the service in 1992, the railroad celebrated 150 years of continuous passenger service in 2014. Planning for the next 150 years of Peninsula rail service, Caltrain is on pace to electrify the corridor, reduce diesel emissions by 97 percent by 2040 and add more service to more stations.
