Umm, why are septic tanks forbidden there?

  Usually because waste water from putrefaction is loaded with nitrogen and bacteria that can contaminate ground water.

    They are supposed to never leak right?

      That depends on the principle, some are actually built to trickle and seep into the ground below. Anyway I suppose that such concrete underground structures are often built on the cheap, and by the very nature of their content they're hard to inspect, so they're bound to develop a tendency to leak over the prospect of decades.
