Im doing an install on one and this is my first time doing it so I need some help with something. The drain is going to be running from the corner of the yard directly down a hill. Im putting the basin in the corner of the yard. Trenching a line all the way down the hill, putting gravel down, laying the pipe in and putting gravel on top. Im stopping about halfway down to "tee" on to a gutter. The question I have is where does the drain pipe stop? Does the hose need to go all the way to the street, which would be under a sidewalk or can it be buried and the water soaks in once it goes down the line stopping before the sidewalk? Thanks in advance.
