Caylor, our gray water ran out a 1 and 1/2 pipe about 10 ft from the house and dumped into a flowerbed!
As a youngster, I recall, not fondly, the freezing January mornings when the pipe would freeze. Dad would fire up one of those kerosene blow torches (I still have it!) and go heat the pipe. What a pain in the kazoo!
Many years later, I replumbed this drain to go through the septic.
You gotta understand, this house was built in the early 1900's, then moved onto a new foundation, which then had a basement dug under it. Dad and his brother's added an inside bathroom years later.
This was in the poor country, way before code.....................
