Constantly Monitoring

Our operators carefully check every part of our treatment process to make sure every drop of water we release to the Willamette River is clean. In 2022, they collected 3,283 samples at the plant and ran 28,550 tests to ensure that our water is safe and that everything is running smoothly.
