The backfill was poured (meaning the dirt was put back and there is no longer a huge hole around the foundation) and the ceiling of the basement was on! We ended up creating a second area for another sump pump, but instead of installing the actual pump, the builder crafted a drainage system just using gravity. If it looks like it isn't working in the future, we can easily just add the second pump, but for now it seems to be working great. The water issues now appear to be solely groundwater, but just to be safe we also lined the exterior of the foundation wall with a water proof sealant. No water here!
