The City of Johannesburg is approving an average of nearly 2000 building plans a month, while some areas in the north of the city are experiencing growth rates of 25percent.
Philip Harrison, Joburg's executive director of development planning and urban management, said figures indicated that the city's population would double within 20 to 25 years.
Infrastructure shortages, informal settlements and management of development pressures were some of the problems that the city faced.
Infrastructure was becoming increasingly critical and starting to impact on development patterns, Harrison said.
Serious under-investment in infrastructure had occurred in the mid-1980s and 1990s. - Sapa
