Physical systems that serve as framework for city growth are called "infrastructure".

Infrastructure alludes to the major offices and frameworks serving a nation, city, or other area, including the administrations and offices fundamental for its economy to function. Infrastructure is made out of open and private physical enhancements, for example, streets, spans, burrows, water supply, sewers, electrical matrices, and broadcast communications (counting Internet network and broadband paces). In general, it has likewise been characterized as "the physical segments of interrelated frameworks giving items and administrations basic to empower, support, or improve societal living conditions".
