ACCELERATED URBANIZATION: RISK TO THE WATER SUPPLY IN GOIANIA METROPOLITAN REGION

Abstract

Metropolitan regions present problems of water supply and sewage treatment, especially those related the protection of watersheds, water treatment and distribution, are areas that concentrate a greater diversification of multiple uses of water resources. Urban population growth associated with the urban sprawl, the degradation of watersheds and the contamination and pollution promote considerable increase in water demands. In this context is part of the Goiania metropolitan region (RMG), which over the past few decades, has been going through an accelerated population growth and urbanization process, demonstrated by demographics data. This work is proposing to debate the impacts of urban sprawl of RMG in the degradation of watersheds, as the risk of water shortage causes in the region, evidenced by the strong growth of human settlements and industrial enterprises in the areas of catchments areas, committing the water quantity and quality of supply. Amongst threats, risks and limits for the water producer system on RMG, the strategy for water management and confrontation of the problem was the construction of Mauro Borges producer system, included the dam the Ribeirão João Leite and a complex of facilities.
