Plant Tours

Come along with us on a tour of our wastewater treatment facility. During the tour, you'll see the various stages of treatment as you follow the wastewater through physical, chemical and biological treatment. Learn how the plant uses alternative fuel sources to conserve energy. See how Sunnyvale uses recycled water for landscaping at corporate business parks and city facilities. Tours can be adapted to meet specific curriculum needs and are conducted Monday through Friday between the hours of 9 a.m. and 3 p.m. Call (408) 730-7717 or email the WPCP to book a tour. One week advance notice is required. Please allow approximately 90 minutes for the tour.

Additional information - Brochures and/or materials about the treatment processes, pollution prevention, water recycling, water conservation, and watershed protection are available upon request. Videos, books and other educational resources are also available for loan.

Extend the value of your visit by touring the Sunnyvale Materials Recovery and Transfer (SMaRT) Station -- it's just a short walk away from the Water Pollution Control Plant. To arrange a tour, please call the SMaRT Station operator, at (408) 752-8530.

Plant Tour Study Guide

To assist teachers in measuring the retention of information learned on the tour, a study guide is available. Students may work on completing the study guide before, during or after the tour.

The study guide asks students to recall facts and figures about the tour, and also asks them to comment on the environmental benefit of the wastewater treatment process.

Much of the information given on the tour is technical and comprehensive but it is presented in an age-appropriate manner for grades 5 through 12.

In addition to actual plant tours, Outreach staff can give a “virtual tour” in two different forms.

1. A powerpoint presentation is available for groups who are unable or do not wish to come to the plant.

2. A video entitled "Wastewater Treatment" which explains the water cycle, the human element in that cycle, the treatment process, and the effect of increasing population on water resources is availble for loan.
