Big Pipe, Big Difference

The Willamette River in Portland is cleaner than it’s been in decades, thanks in large part to your investment. While there is still work to do to restore our river, the Big Pipe Project has dramatically reduced combined sewer overflows (CSOs).

Weekly testing all summer long

Each week during summer months, Environmental Services tests for the presence of E. coli as well as water temperature at five popular public recreation spots along the Willamette. Samples are collected on Wednesdays and test results are posted online by Friday morning – in time for weekend activities.
