What do you mean "the downspouts are going to go into the ground, now that I know the line goes to the sanitary sewer"? Unless your city has a combination sewer system, and most have abandoned the concept, you CANNOT connect your rain gutters to the sanitary sewer.
The city did/does have combined sewer/storm. Over by me they are seperate (2 systems). House is over 100yrs old so I expected the downspouts were going to dry wells or something. When they dug up the sewer line they found a 2ND seperate line several feet above the sanitary that was where the downspouts were piped to. It was 6" PVC so apparently done not too long ago. Our best guess is someone actually ran a line for the storm water when or after the storm/sanitary split project came to our neighborhood. This was from what I understand in the 50's-60's, so maybe in the 70[s-80s someone did this work.
