Summary: The low amount of natural resources available took society to change its
consumption habits economically, politically and environmentally. Due to that, this
dissertation presents strategies to best conserve and use water in order to reduce
the consumption of potable water as of techniques of rational use and by the
utilization of non-potable water sources. The building chosen for the development of
this study was the Central Restaurant of Vale (Restaurante Central da Vale), which
possesses a covered area of 7.521,3 m². The methodology utilized contemplated
initially the evaluation of consumption of potable water in comparison with the nonpotable
water that was offered by the building. It is important to highlight that the offer
of rain water presented a volume of 7.588,3 m², while the offer of condensed water
represented a volume of 489,6 m²/year. It was determined that the grey water
produced by the building represents 1.982,7 m²/year, whilst the black water
demonstrated a flow of 5.843,9 m²/year. It was analyzed the possible leakage of
sanitary toilets, concluding that they represented 0,2% of the total water consumed.
Subsequently, it was applied the hydric balance reconciliation (BHR) developed by
Teclim Network from Federal University of Bahia, for the reconciliation of the data of
leakage measured and estimated. The deviation found in the measured leakage and
reconciled was insignificant, since the sectorized consumption of potable water did
not present any alteration. Posteriorly, it was developed the study of technical and
economic viability for alternative non-potable water sources (rain water and
condensation) as well as the implantation of saving devices installed in the Central
Restaurant. It was concluded that the usage of both non-potable water sources
(condensated water and rain water) as well as the implantation of saving devices
would imply an economy of 21.997,4 m²/year, corresponding to a reduction of 34,6%
of potable water demand by the use of alternative sources.
