Infrastructure includes constructed facilities and associated natural features that shelter and support human activities, such as buildings of all types, communications, energy generation and distribution, transportation of all modes, water resources, and waste treatment. An example of an associated natural feature is a wetland serving as part of a stormwater management system. Since infrastructure services are essential for human health, productivity, safety, and quality of life, infrastructure's value is equivalent to that of these human qualities. However, infrastructure also has direct economic importance. In 2008, for example, new construction put in place was $1.072 trillion, or 7.42% of the gross domestic product (GDP) of the United States. Considering that renovation, operation, and maintenance expenditures are of similar magnitude, infrastructure exceeded 10% of the GDP. Its value is a major element of wealth, representing 68% of U.S. fixed assets.
