Deep Sanitary Pipes
If you love roller-coasters, you'd LOVE this ride! A drop of over 500 feet in no time flat! This sanitary pipe starts at just 1 inch below the first level finished floor elevation and dives 514 feet straight down to end up almost a tenth of a mile below ground! Wow! If it weren't a sealed system, you'd think they were trying to get rid of their waste by pumping it into the center of the earth!
