The ancient practice used by the Romans for aqueduct construction involved a sophisticated engineering technique, primarily utilizing gravity to transport water over long distances. They built a network of channels, bridges, and tunnels to maintain a steady downhill gradient. Romans engineered impressive stone arches to support these structures, allowing aqueducts to traverse valleys and uneven terrain. This ingenuity facilitated the provision of fresh water to urban areas, enhancing public health and enabling urbanization. The aqueduct system exemplified Roman engineering prowess and laid the groundwork for modern water supply systems, showcasing their reliance on advanced technology and infrastructure.
