While the concepts may not be difficult, the scale often is.
See the Milwaukee deep tunnel system, storing 521 million gallons in 28.5 miles of tunnel.

But it does work: https://urbanmilwaukee.com/2014/06/12/murphys-law-the-remarkable-impact-of-the-deep-tunnel/ https://urbanmilwaukee.com/2014/06/12/murphys-law-the-remark...

- hexane360 9y agoYep, definitely. I brought up Milwaukee because I have a better understanding of it and its effects. As hard as 521 million gallons is to visualize, 17.5 billion gallons is. . . 34 times worse.
- sarcher 9y agoTotally, 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.
