The need to maximize a limited access to water for both human consumption and agriculture might explain the fact that both Peruvian cultures - both agricultural civilizations - used underground aqueducts to collect and transport water to reservoirs that were located nearby. For instance, the rivers that supplied the Nazca people did not carry any water during part of the year, so they conceived an innovative system that allowed them to collect the water from the rain that filtered through the ground into underground galleries, which allowed them to prevent the loss of that water - they inhabited a desert area, after all. The Chavin civilization also inhabited arid and extensive coastal areas that required ample and complex irrigation systems, hence the importance of saving and transporting water.
Changes through rapid population growth, advancement in transportation, and factory system led to the industrial revolution which was the transition to new manufacturing processes in Europe and the US during the 18th and 19th Centuries. In this period agricultural societies transformed from agrarian and handicraft economies to industrialized societies dominated by machines and industry growth where the transcontinental railroads, cotton gin, electricity, and other inventions completely changed the lives of people.
