Drinking water source protection
McKenzie River

The McKenzie River is the sole source of drinking water for nearly 200,000 people in the Eugene metropolitan area.

Recognizing the importance of this valuable resource, EWEB developed a Drinking Water Source Protection Plan in 2000, which includes a risk assessment of all potential threats to our drinking water. As part of this effort, EWEB launched an ambitious drinking water source protection program to protect the McKenzie and the high water quality EWEB customers have come to appreciate.

McKenzie Watershed Emergency Response System

EWEB has worked closely with federal, state and local agencies to implement the McKenzie Watershed Emergency Response System (MWERS).


EWEB has several programs designed to help farms become more economically viable so the land continues to be used for this purpose, while also encouraging farmers to use fewer chemicals to protect the watershed.
