AVALIAÇÃO DO IMPACTO DO CRESCIMENTO POPULACIONAL EM UM SISTEMA DE ABASTECIMENTO DE ÁGUA

Abstract

Population growth is one of the variables that put pressure on water resources, so it is necessary to assess future demands for water in the face of demographic projections, ensuring instruments that guide effective actions against supply problems. The general objective of this work is to study the population growth rates of a region and apply them to the average daily water consumption of a subdivision, located in the city of Santana da Ponte Pensa (SP). Using computer simulations, the study evaluates the behavior of the supply network every five years, in order to verify the hydraulic elements according to the parameters of NBR 12218 (ABNT, 2017). This is a research based on population projections and growth rates, which served as support for carrying out computational hydraulic simulations of a water supply system. The evaluated network is located in Santana da Ponte Pensa/SP and the software used in the simulations was Epanet 2.0. In the period from 2020 to 2040, the projection of population increase was from 1,448 to 1,589 inhabitants. Being a low growth, it did not generate failures in the distribution network, the problems arose only when the subdivision reached 3,278 inhabitants.
