Infrastructure typically refers to the technical structures that support a society, such as roads, water supply, wastewater, power grids, flood management systems, telecommunications Internet, telephone lines, broadcasting, and so forth. In the past, these systems have typically been owned and managed by local or central governments. These various elements may collectively be termed civil infrastructure, municipal infrastructure, or simply public works, although they may be developed and operated in the private sector or in public-private partnership in additional to in the public sector.
