Delta Diablo (District) is proud to showcase the award-winning public health work of our staff and wastewater processing services with tours of our treatment plant, including our laboratory.  

Each tour is tailored to the group size, focus of school curriculum (if applicable), and any physical disabilities.  Tours include climbing steps and are mostly outdoor.  For your safety, all guests must wear shoes which cover their whole foot (no heels, open-toes, or sandals please).  We also recommend sunscreen and appropriate headgear for sun protection.  

Our plant tours are open for children ages 10 years and up.  We do ask for adult chaperons to accompany school groups:

  • 5th-6th grade (10-12 years old): 1 adult per 7 students
  • 7th-8th grade (12-14 years old): 1 adult per 10 students
  • 9th-12th grade (High School): 1 adult per 14 students.  

If you, or a group you represent, are interested in being included in a future tour, please contact 925.756.1900 or  

Please note that tours may need to be modified or cancelled for guest safety due to weather or major construction at the plant.
