Free Buses for Schools

The Sanitation Districts of Los Angeles County are offering you a free field trip to our facilities (while funds last). If you qualify, we will reimburse you for your bus transportation costs to visit either a wastewater treatment plant, materials recovery facility or one of our other sites. This is a unique opportunity for you and your students. You will get to see, learn, and really experience what happens to your sewage or trash. It's fun, interesting, and educational!

Please note that funds for buses are limited and may run out. A school is eligible for one free bus during the school year.


To be eligible for this exciting program, you must meet the following qualifications:

  1. You must teach 5th – 12th grade at a public or private school. College instructors at accredited four year universities or community colleges are also eligible.
  2. Your school must be located in the Sanitation Districts’ service area. Our service area covers 850 square miles and encompasses most cities and unincorporated areas in Los Angeles County. This area includes most of Los Angeles County, but excludes most of the City of Los Angeles and a few other locations. If you would like to confirm whether or not you are in our service area, please contact us.


People from over 100 countries have toured Sanitation Districts’ facilities to learn about our state-of-the-art methods for wastewater treatment and solid waste management. We invite you and your class to also take a tour!

With our free bus program, you can visit one of our facilities. If your school is located in an area where we provide both wastewater and solid waste services, then you can visit either a materials recovery facility/landfill or wastewater treatment plant. Otherwise, you will visit the type of facility that serves you. Please see the attached service area list for more information.

Our most popular facilities to tour are the San Jose Creek Water Reclamation Plant and the Puente Hills Materials Recovery Facility, both located just outside the city of Whittier. At the San Jose Creek Plant, you will learn how your wastewater is cleaned and recycled for uses such as landscape irrigation. At the Puente Hills Materials Recovery Facility, you will see what happens to your recycling and trash, and even have the opportunity to visit a closed landfill if you are interested.

Tours take approximately 1½ hours.

Your students will enjoy and learn more from their field trip if they know a little about what they will see. Please take time to introduce your students to wastewater and solid waste concepts such as recycling, water quality, and others.

Follow the Flow…Where Solid and Liquid Waste Come From…And Where They Go, a teacher’s guide to use before and after Sanitation Districts’ tours, is available to help you prepare your students for their tour. Follow the Flow provides you with background information, classroom lessons and hands-on activities. The guide is correlated to California State Content Standards.
