Avaliação dos impactos causados na rede de distribuição de água pelo aumento populacional dos bairros da Penha e Ponta do Seixas, João Pessoa-PB

Abstract

In this work, an analysis was made of the impacts of verticalization and the floating population in the water supply network of the neighborhoods of Penha and Ponta do Seixas, located in the municipality of João Pessoa, capital of Paraíba. It is noticed that with the increase in population, caused by both phenomena, there is an increase in the demand for water, which directly impacts the sizing of the system. For the simulation of such impacts, it was necessary to use the EPANET/LEHNSNET software. Initially, the network that supplies both neighborhoods and its characteristics, such as height, diameter and length of the stretches, were collected. The water supply simulation in EPANET / LENHSNET was elaborated in 4 scenarios. Scenario 1 was the dimensioning of the neighborhood network considering the resident population of each neighborhood as the population served and an increase referring to the floating population, in 2010. Scenario 2 differs from 1 in that 2 is for the end of the plan, considering the same target groups. Scenario 3 is also for the year 2042, however, instead of considering 4 people per household, 6 people per household will be considered. For scenario 4, in addition to the population of scenario 3, the flow of 2 possible buildings that could arise in the region was considered. It was verified that the main impacts caused by the verticalization and the floating population on the water supply network were: the increase in the demand for water requested by the neighborhoods; increase in pipe diameters and increase in the cost of installing new pipes.
