A Place for the Brown Stuff

Problem #2 (Not too bad so far), How to fit the septic system tank into a hole that contains more Rock then an episode of The Flintstones. So in comes the big guns, a 12 tonne rock breaker spent 6 hours breaking the rock and digging an enormous hole to fit the tank. The final product isn't too bad, except the huge pile of rock left over. Good thing the neighbor wants it to do some retaining with.
