Water quality
The Eugene Water & Electric Board's water quality is truly extraordinary. Due in
part to our pure source, the McKenzie River, nearly 200,000 EWEB water consumers
are getting some of the cleanest, tastiest water on the planet.
So good, in fact, that Organic Style magazine has named EWEB's water the best in the nation.
EWEB's extensive treatment process allows it to easily meet all federal and state
water quality requirements. In fact, EWEB's water has never violated a state or
federal water quality standard.
EWEB has an aggressive program designed to keep the source of our drinking water,
the McKenzie River, clean and pure for the citizens of Eugene. Learn more about
