Sustainable Alternative Water Sources Use for Lowering …
827
From the average flow calculated for the five models in the study area and the
number of devices for each model considering the average daily usage time, it is possible to estimate the daily or weekly volume generated. Laboratory analyzes were
performed according to the methodology presented by the Practical Handbook on
Water Analysis prepared by the FUNASA—Fundação Nacional de Saúde (National
Health Foundation), Brasil (2013), in the Chemistry Laboratories (free residual chlorine, apparent color, pH, total suspended solids and turbidity) and of Microbiology
(total coliforms and Escherichia coli) from the collection of three samples for each
source.
The study proposes the use of a water volume, both generated separately by
air conditioners and rainfall, which is not currently used on the campus. Thus, the
opportunity to foster an environmental awareness in the Institution regarding the use
of alternative water sources and the rational use of water resources is envisaged.
In this sense, observations were made to assemble the final system, contemplating
both rainwater and water generated by air conditioners. The prices of the materials
