That is true, and it's an opportunity. That water should be captured for farm use. However by the time the water got to those cites it has (hopefully) been used many times.

Because no one can drink this water. Obviously on a global level water can't ever be wasted. So talking about water waste must necessarily be about available water. Runoff is a waste in that sense.
True, but how do you know they didn't already make that adjustment? I can't find any reference in the original report.
"household water usage with a sewer system is a null usage. Reducing that does almost nothing - all the water used gets recycled downstream by the next city downriver"
Except in Seattle, San Francisco, New York, Los Angeles, and many other coastal cities, where the sewage outfall is in the ocean....
"...septic systems waste water."
Functioning septic systems don't store water. They drain it to a field, and it goes wherever any other form of runoff would go. I don't see how you arrive at the conclusion that this is "wasteful".
