Sump pit placement ??

[maarass]

Trying to deside where to place the sump pit. I had one in but it was partially under the footer so we filled it in. I will have both interior and exterior drain pipe to daylight. The sump is for whatever that doesn't handle (where right at the water table) The perimeter drains will exit out the back of the house near our walk-out. Totally oppisite at the front of the house is where the water problem is because of the footing depth below grade. In this senerio where is the best place to put the sump pit ? Thanks
