Consumo de água e tarifa social em áreas de baixa renda: estudo de caso das comunidades de Santa Marta, Complexo do Borel/Casa Branca e Complexo da Mangueira.

Abstract

The city of Rio de Janeiro, since its foundation, struggle with the serious problem of water supply. Over time all the little sources of water around the city were being destroyed by disordered growth of population and the only way was looking for the sources of supply in other cities. Actually 80% (eighty percent) of metropolitan supplying comes from a single source: Guandu River. This was possible due the transposition of the Basin of Paraiba do Sul River to Guandu River occurred in the 50 s decade. This essential source of supply, where has been built the biggest water treatment station in the world, ETA Guandu, is coming to be exhausted and we will be able only to take and treat a small portion of water more than treats today. To shift this major problem for the future, while we don t invest in new alternatives, we have to think seriously in "consuming with responsability." In this context, areas of low-income embodies 801 slums and more than 1.500 of irregular subdivisions, representing in 2010 almost the third part for the total population and consuming 10% to 15% of all water production from the metropolitan region, should be permanently encouraged to contribute to reduce consumption. Studies presented in this dissertation in three different methodologies denotes to a point above the average consumption of the same national profile population. This challenge is extremely difficult because requires behavior changes and everybody engaged, either the local Sanitation Company.
