At my girlfriend's mom's house she purchased last year. It's an older home built in the 50's. They are having drainage problems and flooding in the walk out area below grade (see pictures). We popped up some boards and the upstairs sewage is draining in the open under these boards. Is this normal? I thought sewage should be to a public sewer or septic hidden from open air.
Water is coming from under steps too, so i think it's bad drainage and we started pulling those boards and see crap water..
