what happens is, if the surrounding area gets rained on enough, the tank will float. Iv'e seen a concrete ceptic float half way out of the ground after heavy rain, because it wasnt filled with water. The only way to fix the problem was, to remove the tank, re-dig the hole, then put the tank back, not much fun.
They didnt fall for that trick again, this time the tank was filled with water immediatly.
