Get a behind-the-scenes look at our vital work

Have you ever wanted to see how the water we use is cleaned up and returned to nature? Then consider taking a plant tour of the District’s Nine Springs Wastewater Treatment Plant. On our plant tours, you’ll learn about our treatment process and how you can help protect our shared water resources.


The first Friday of every month at noon (excluding holidays), the District offers an hour-long tour of the treatment plant to anyone who would like to attend. The tour is open to all ages, but all minors must be accompanied by a responsible adult.

Tours are free, but prior RSVP is required. Please RSVP by noon the Thursday before the tour via the form below. Tours may be canceled due to weather or other factors. If the tour is canceled, the District will contact those who have RSVPed.

If you can’t make the open tours, you can still schedule a small-group tour for five or more people at any time during District business hours.

Plant Tour Policies and Procedures

To ensure the safety and enjoyment of all tour participants, please review the following information.

Attire

Closed-toe, sturdy, flat-soled shoes are required of all tour participants. Sandals, open-toe shoes and high heels are not allowed. We suggest wearing comfortable clothes as there will be a lot of walking and stair climbing on the tour. We do not cancel our tours due to weather unless it poses a danger to our visitors, so dress appropriately for the weather.

Safety

It is important that visitors follow all safety guidelines. Prior to the tour, please review the District’s safety information and expectations for tour groups and share this information with all members of your group.

Accessibility

The standard tour route includes stairs and a good deal of walking, sometimes on uneven surfaces and grass. Some parts of the route are not accessible to individuals with physical disabilities. However, with advance notice, we can make modifications to the route to accommodate all visitors.

Group Size

Maximum Group Size: To keep tour group sizes manageable and help ensure adequate supervision of groups of children, large groups will be divided into smaller ones. Individual tour groups will generally be capped at approximately 20 people, or one class.

Minimum Group Size: Tour groups of 5 or more people are recommended. We try to accommodate all tour requests, so if you are an individual interested in a tour, you can still fill out the tour request form or contact us to request a tour. We will try to combine these individual requests with other tours when possible, so individuals may need to be flexible on the date and time of the tour. Individuals or small groups are encouraged to attend an open First Friday tour, held the first Friday of every month at 12 noon.

Chaperones

The District requires adult chaperones for tour groups of minors. Each tour group must have an appropriate number of adult chaperones (not including the tour guide), as defined by grade level below:

  • High school: At least one adult chaperone per tour group
  • Middle school: At least one adult chaperone per group of 20 or fewer students; at least two adult chaperones per group of 20+ students
  • Elementary school: At least one adult chaperone per seven students
  • Younger than elementary school: At least one adult per two children
