Neste trabalho é realizado o estudo da utilização do sistema de bombeamento direto em redes de abastecimento de água utilizando um sistema de controle PID para o controle de pressão de redes de distribuição de água, por meio de um conjunto motobomba acionado por inversor de frequência. Para isso foi utilizada uma bancada experimental instrumentalizada simulando um sistema de abastecimento real (LENHS/UFPB). A eficiência hidroenergética do sistema de bombeamento direto foi avaliada a partir de testes utilizando o cenário convencional (sem controlador) e empregando o sistema de controle em situações de máxima e mínima demanda. Também é feito um estudo de caso na Zona de Pressão do Reservatório R-11 (João Pessoa/PB) com o intuito de atestar que a implementação do inversor de frequência pode gerar ganhos hidroenergéticos no sistema de abastecimento. Os resultados obtidos demonstraram êxito do sistema controlado na medida em que o uso do controlador acoplado ao inversor de frequência proporcionou redução das pressões de serviço e do consumo de água. Os resultados também foram positivos para o estudo de caso, na medida em que houve economia de energia e reduções das pressões fornecidas.
