Cane Hill’s main water tank was at the pinnacle of the structure, the final hazard to overcome before the roof. It was absolutely enormous, towering above and around us. It almost filled the entire internal area of the water tower – I wondered if the tank’s dimensions had dictated the dimensions of the water tower itself.

There was a tiny gap between the tank and the water tower’s external walls and this formed a walkway around the entire tank. The space was well lit as we’d reached the height of the six lancet windows; which meant there were twenty four windows this level rather than eight at the lower levels. I suspect this was to allow engineers to inspect the tank easily.
