Avaliação dos impactos da verticalização na rede de abastecimento de água do Bairro do Altiplano, João Pessoa - PB.

Abstract

This work analyzes the verticalization impacts in the Altiplano neighborhood, located in João Pessoa city, Paraíba’s capital, in the water supply network using EPANET / LENHSNET software. Initially, the hydraulic characteristics of the district's water supply system and the new built buildings were collected. It was found that in order to suply the new buildings water demands, it was built by CAGEPA - Paraíba Water and Sewage Company - an water supply network expansion, completed in 2015. The water supply simulation in EPANET / LENHSNET was elaborated in 3 scenarios. Scenario 1 was used the supply network of the Altiplano neighborhood without the network expansion and the 2015’s estimated population. Scenario 2 was considered the water distribution network that operates in the neighborhood currently, in other words, with the enlargement made, and the 2017’s estimated population. Scenario 3 is a future scenario with the projection of the population to 2037 (20 years) and a 1/3 increase in the flow of new buildings. It was verified that the main impacts caused by the verticalization on the water supply network were: the increase in the water demand, that reaches 35.96 l / s (more than half of the demand of the neighborhood currently); increase in pipe diameters and increase in the cost of installing new pipelines, equivalent to a 59.2% increase in the value of the neighborhood distribution network before supplying the new buildings.
