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.
