When the population became bigger they decided to expand their city but then in the height but what to do with water supply. After consideration they build up the pump that was pumping up the water to the highest level and from their it was flowing downwards on the aqueducts, so that people could use water for their needs. The had everything sun with it warmth, water giving a life and peace with love to support.
