Otimização em Rede de Distribuição de Água

Abstract

Water distribution networks (WDNs) require proactive maintenance methods in order to ensure its correct functioning. Failures, such as leakages and pipe deterioration, lead consumers to bad experiences such as having water supply services interrupted. In this paper, the focus is to improve a WDN. First, we set a pattern curve and the objective function will achieve a pre-established value of minimum pressure to all nodes in the system. Three options are available: pipe replacement, pipe cleaning and leakage fixing. Thus, by considering a limited budget, the most economic solution must be determinated to attend the operational pressure and, at the same time, lead to the minimum mean pressure during 24 hours of operation. In this development, we used the Particle Swarm Optimization (PSO) method. The results point to a tool with huge potential of implementation in WDNs rehabilitation.
