Treatment Plant Tours

Drinking Water Treatment Plant Tours

We have five water treatment plants on the Clackamas River where water is taken out of the river and treated before it is used as drinking water. Water treatment is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from the raw water. The goal is to produce water fit for human consumption, or Drinking Water.

Water at these treatment plants is treated to meet legal limits set by the Environmental Protection Agency (EPA) on the levels of certain contaminants in drinking water under the Safe Drinking Water Act (SDWA). These legal limits reflect both the level that protects human health and the level that water systems can achieve using the best available technology.

See first hand how we take water from the Clackamas River, clean it, and treat it, so it is ready to be used in the community by scheduling an in person tour or watching the video below of the water treatment plant where your drinking water comes from.  Want to schedule a tour or not sure which video to watch, contact our Public Outreach and Education Coordinator at [email protected].
