The City of Palo Alto Watershed Protection Group wants to help with your next event!

Need a guest speaker, activity, or someone to staff a table at your event? The RWQCP offers several fun, interesting, and educational options to get the word out about preventing water pollution in our creeks and Bay.


Event topics are usually customizable and are provided at no cost to residents and businesses in the RWQCP service area.

Hosting a table – we staff special event tables at Earth Day, Science Fairs, neighborhood groups, and other special events. Ask us about our popular Wheel-o-Trash game!

Workshops – try a fun, hands-on workshop with topics like "Make Your Own (less-toxic) Home Cleaning Products" or "Bee-autiful Gardens!" (less-toxic, pollinator-friendly pest control).

Tours – take a walking tour of the Regional Water Quality Control Plant and see how operators, scientists, engineers, and educators work together to clean 20 million gallons of wastewater every day before it's released to San Francisco Bay. To schedule a tour call 650-329-2396.

Litter and trash cleanups – let us help you coordinate a creek or neighborhood litter cleanup!

Stormdrain stenciling – we'll provide the tools to paint a bright red message "Flows to Creek" message around local school storm drains. This is a great environmental project for youth groups, clubs and school programs.

Informational talks – Let us bring a "brown bag" or technical talk to your community or professional group. Speaking and special event topics include:

  • Watershed 101 (what is a watershed, why we care, and how to protect our local creeks and Bay)
  • Plastic pollution and the Bay
  • Modern pollutants in the Bay
  • Clean and sparkling! Less-toxic cleaning at home (hands-on workshop)
  • Less-toxic gardening (pest control that is safe for your family, pets, and Bay)
  • Medicine disposal (medicine disposal service is possible at some events)
  • ​Antibacterial products-how they can harm your health and the Bay

For more information call 650-329-2122 or email us at cleanbay@cityofpaloalto.org
