Relative to Philadelphia's water and sewer systems, this includes pipes, pumps, plants, water works, reservoirs and other water storage facilities, and other aboveground and underground structures related to the city’s water supply, sewerage system, and drainage. In a larger sense, infrastructure includes many other human-made structures, including roads, highways, bridges, tunnels, canals, and other things of that nature.
