Sistema de aproveitamento de água de chuva para mercados públicos de João Pessoa

Abstract

Water is essential to the performance of the mainly physiological functions and its consumption is increasing day by day. The United Nations (UN) considers that the water volume that is sufficient for human activities, economic and social, is 2,500 (two thousand) cubic meters of water per capita per year. But in many regions water availability per capita is below 1,500 (one thousand five hundred) cubic meters, this situation is considered critical. The system of harnessing rainwater for a public model market in João Pessoa city, Paraíba state is adapted to minimize the environmental and economic issues. The case study to be presented is for a new popular community with 1,336 houses. The study emphasizes the critical analysis of social reality, which favors an approach to the natural and social aspects. The main objective of this work is to include in the design of a public market a system to use rainwater in toilets in the market, and to verify the acceptance or rejection of the residents and traders in the public markets. For this purpose, Rippl method was used to design a single reservoir to attend the market demand for unpotable water.
