digging out the water tank

This is the water tank that was created by my dad in the 60's. It was in the days before pumped water, and each house had to draw water from a hand pump down the road. Dad built the tank to store water from the roof, and them pump it into the house. Pretty modern for those days. He built it by hand with his dad, and used lots and lots of concrete....which meant that I had to struggle to remove it! Why remove it? Because it is sitting right in the place where my bedrooms will go. I had to use two jackhammers and a JCB over three days to remove it.
