This doctoral thesis aims developing a methodology and implementing it on software in
order to evaluate a water supply system (WSS) hydro-energetic performance, as well as
applying it on a real scale WSS. This paper was carried out in two stages: 1) modeling
the hydro-energetic performance evaluation process, establishing of formulations to
calculate hydro-energetic losses and implementing methodology on software; 2)
applying the methodology at a real scale WSS, which required monitoring of hydraulic
and electrical quantities and simulating this WSS at Epanet 2.0. The first stage results
consisted at defined hydro-energetic losses and conceptualize hydro-energetic
performance on the proposed methodology, which consists sequences of actions and
mathematical formulation to calculate hydro-energetic losses at the WSS, as well as to
evaluate WSS hydro-energetic performance and, finally, at methodology
implementation in a software using Visual Basic for Applications (named as SADHE2A)
and successfully tested at the WSS with synthetic data. The second stage results are
related to methodology application at WSS of Guanabara (located at Ananindeua city,
Pará, Brazil), using SADHE2A – versão Beta, in which were identified water global
losses of 55.42% and electrical energy global losses of 58.31% (both classified as “bad”
by the methodology), resulting in an economical deficit of 17,981.77 R$/month. This
value is equivalent to 57.61% of electrical energy costs, since raw water pumping to the
final water costumer. Finally, the methodology developed has met the research
expectations to calculate the water losses and electricity consumed losses and to
evaluate the hydro-energetic performance of the WSS in Brazil and world.
