New construcion basement drainage
I am pouring the footings for my new construction in the next couple days.
I will have a walkout basement which will have 2 baths in it. I put a 4" pipe under the footings for the main drain line.
I have a question on the connections between the drain pipes for the bathrooms(and couple other drains) to that main line.
The bathrooms are about 30-40 feet away from the main drain line. Don't there have to be enough slope for the drain to work properly? How can I accomplish that? Also, there are footings for interior walls in 2 different spots between the basement drains and the main line. Where do the drain pipes go in those spots? Through the footings? under the footings?
I am trying to figure out the connection details and would really appreciate some help in that regard.
FYI, I will have a plumber as I haven't decided on one yet, but I need this to help with pre planning for footing pour.
Thanks

Our plumbers will chime in shortly, but at 40' you'll need 10" of drop in the drain pipe at 1/4" per foot. That's a long way. No way to relocate the bathrooms to a more convenient place? Is your plumber going to stub up prior to the pour?

Try to find out the elevation of the sewer line at the street. You certainly do not to be forced to pump water out of the low height of the pipe or internal system you are creating. This happens frequently with full depth basements on a lot that is lower than the sewer main at the street.

Chandler,
I won't have a plumber before then(pour is tomorrow hopefully), and the slab won't be poured for a while so I am not concerned about that, it's just the footings for the interior walls.
Dick,
The lot is actually a lot higher than the city sewer. The lot slopes down and the distance between the house and the city sewer is about 200 feet. So the only concern is where to put the pipe for the main drain line, and how to handle the interior footers.
I think I should put the main sewer pipe a couple feet below the footings, and bring the bathrooms drain pipes right under the interior footings, by the time the get to the main drain line, there will be enough slope? I hope I am making sense.
