The wall will be cast in place concrete and is about 100' long and 5' tall at it's tallest point. We are able to get the valley gutter to drain to the end of the wall but there isn't a good place to put an inlet at the end of the wall as it will be a slope with no good place to tie into.
Any thoughts on the best wall to have an inlet behind a concrete retaining wall? We are planning on having a valley gutter behind the wall and probably the best way to drain it is to put an inlet behind the wall and pipe it under the wall to a roadway curb inlet.
