A One-Question Waukesha Water Q & A

The City of Waukesha uses, on average, 9.8 million gallons of water daily, according to SEWRPC (see bold-faced updates).
(And feel free to peruse the longer contextual discussion there.)

It has talked about seeking a Lake Michigan diversion of 24 million gallons daily.

That's a 147% increase over its daily usage, though also according to SEWRPC - - same bold-faced updates), its service territory is essentially built out.

Even the low end (20 million gallons daily) mentioned by Waukesha as its diversion total more than doubles its average daily usage.

So why the huge overage?

SEWRPC infers the same question, here.
