In the hydraulic oil tank. Where that's located depends on which model of backhoe you have.

A backhoe would be the better option since a backhoe can dig deeper than a skid steer. Also, the weight of a backhoe would allow it not to move anywhere. Plus, a backhoe can remove the septic tank if that was needed. I would suggest looking at backhoes from Catepillar.
