  1. Why is no one realising that even new sewage systems use gravity to work? I get not everyone is a plumber/GC but hello! Like us they used to drain sewage INTO a water source (not a great idea but obviously we've learned a lot and engineering has come a long way since then?) only now we treat it first. So Chicago being basically at sea level (as he stated) ment they couldn't just dig below the street, oops I ment "errr the fuckin street' (sorry bud πŸ‘) as you can't drain it without pumps as places like New Orleans etc. have to as well as install check valves. (these fittings fitted inline prevent fluid from going the other way which would of caused more problems many worse) Obviously without the electrical system and many other technology we have today this wouldn't be possible therefore the only real solution was to raise the streets or run pipes above ground on a pitch 1/4" per 12" which if far away would soon be overhead and any new construction past even higher. This exact equation is actually a pretty important slope as less will cause the poo to sit in the pipe and more will cause the liquids to run too fast, again leaving many forms of poo (like after Taco Bell or lots of chocolate.. you get the idea) to sit in the pipe dry and lead to clogging it. Again this exact slope used today was learned over time. Obviously down pipes are a different story as well there's no way poo is going to get stuck going straight down and if it does its only going to build up so much till the pressure of the water above forces it thru and cleans the pipe. Anyway this is why this was the only real/good solution. Unless someone finds a way to do much more than change the flow of a river but lower the entire oceans level which I'd love to hear if you find one as would many people. Just to explain to those who don't fully understand plumbing, now you have the knowledge as far as slope for your own sewage project.
