      Don’t they lead to the same system? If there was a leak in your roof over your shower, your shower drain will also be a storm drain

        Storm drains usually lead straight to creeks, rivers, or other bodies of water, whereas your sewage goes to a water treatment facility first. Totally separate systems (in most places)

        Usually not. When they do it means a big storm overwhelms the sewage system and raw sewage is released someplace. Most places get a storm this big several times a year.

        For people on septic systems it isn’t unheard of for shows to bypass the septic system and go directly to the drain field - only water from your toilets and kitchens needs treatment (as a parent I can inform you kids sometimes poop in the tub so this is a bad idea). I’ve also heard of people diverting their shower to a tank that is then reused for flushing toilets - if you live where water is scarce this might be a good idea, but for most of us it isn’t worth the costs.
