Resumo
Water losses in water distribution systems are usually high, and generate
thus environmental or economic impacts due to mainly an inefficient management by
the water utilities. This issue requires the adoption of best practices that improve the
operation of water supply systems managed by these companies. A powerful tool that
can be used for this purpose is the hydraulic modelling of water distribution networks.
Once calibrated, the water supply system model can generate practical information and
data to assist in the diagnosis of the system as well as to reduce water losses. This study
focus on assessing leakage losses by means of the hydraulic model calibration applied to
the sector Parque Santa Rita – Zona Alta, located in the city of Goiânia, GO. The software
EPANET was used for the hydraulic simulations and the inverse problem was solved by
the Genetic Algorithms method (GAs). The developed model reproduced satisfactorily
the hydraulic behaviour of the water network since the calibration resulted in good
agreement, and it has been determined low rates of leakage losses for the entire sector.
However, it has been shown in this study that the normal distribution of nodal demands
does not reproduce the hydraulic behaviour of the water distribution network.
