The midwest home I grew up in, constructed in the 70s, had multiple drains in the basement floor which was also where the laundry hookups, wash basin, water softener, HVAC w/humidifier and air cleaner etc. were located. It was nothing special for the area. Homes out on the west coast are constructed much less robustly from what I've seen. I presume the mild climate has a lot to do with it.
