The water distribution systems (WDS) analysis focuses to develop optimal designs that allow implementation of water supply systems with quantity and quality needed for the human community consumption; therefore, it is necessary to characterize system topology and hydraulic variables. For identification of the most sensitive parameters involved in population density changes, three comparisons are presented related to (1) hydraulic gradient surfaces, (2) pressure surfaces, and (3) specific power maps. According with this, behavior patterns can be defined based on the networks' characterization and alterations that may occur verifying minimum design conditions of compliance and operation. The results show hydraulic gradient surface changes are proportional to demand growth, highest and lowest pressure nodes remain same for near locations, and the spend energy tends to be constant when taking a relative percent difference.
