Celebrating our Groundwater Source

Portland geology by tram, train, and footAt the Portland Water Bureau, we always appreciate groundwater.

The city's 27 wells give us a reliable water supply during turbidity events and long, dry summers.

Groundwater was especially important this year. This long, dry summer meant we used groundwater more than we ever have before.

You can learn more about the rock layers that make this all possible by taking a self-guided field trip of Portland's geology (written by Oregon's State Geologist!).
