Can we garden over septic pit?

Instead of lateral lines from our septic tank, we have approximately 15' by 20' by 5' deep septic pit filled with gravel. We live in a wooded area and it's the only place that gets much sunshine. If we tilled up our nice zoysia yard that we've worked so hard to grow and planted a garden, would that pack the soil too much for the pit to work properly? Since we live on a lake, we should have water available for ocassional flushing, but we could give up indoor facilities completely if we needed to .

If you had a minor flood, or a big thunderstorm, the water level might rise to the top of the ground for a couple of days, and carry all kinds of interesting bacteria to contaminate any veggies that touch the ground (pumpkins, tomatoes, squash, lettuce etc.). Don't think I would do it. Consider a small greenhouse on the spot instead with plants in boxes.
