Totally, the scale can be outrageous. As you mentioned, Milwaukee's system is huge - but it works.

"Too Big, Will Fail" is a pretty common refrain from anti-infrastructure personalities, but when it comes to simple civil engineering projects it doesn't matter what the scale is if the mechanism is proven. Solving CSOs isn't the Hyperloop, it's just building a bathtub big enough in the right place and figuring out how to drain it appropriately when it fills up.

Milwaukee, Chicago - these are examples that prove that stormwater management is a solved problem. So let's apply that solution to places where the problem still exists.

Anyways, cool link, I didn't know about Milwaukee's system.
