The rain drainage flow from roofs area was calculated, and equal to 177.81 L/min.
The volume generated by air conditioners was estimated, equal to 289.36 L/day. All
parameters for water quality remain standardly good so that water can be used for
gardens irrigation, floors and rooms washing, so that preserving drinking water. The
study demonstrates economic value of use of the alternative water resources and that
sustainable based actions are at reach of any academic center.

1 Introduction
Over the centuries, excessive use of water resources and permanent withdrawals for
various purposes have considerably reduced water availability and have produced
numerous shortage problems in many regions of the world (Tundisi 2009).
Man’s survival is related to his ability to reuse scarce resources, particularly water,
as well as its protection, recovery and reuse (Mancuso 2003).
Matching the Sustainable Development Goals (SDG) and with the goal of achieving the Millennium Development Goals, a substantial change in society’s production
and consumption patterns is required. Water conservation practices provided by the
control of increasing demand with the expansion of water supply, using alternative
sources of water, such as the use of rainwater, can be defined as a set of practices,
techniques and technologies that improve the efficiency of water use (Gonçalves
et al. 2006, p. 45).
The National Environmental Policy Program (A3P) (Brasil 2009) and the Environmental Management Program (PROGEA) of the Federal Institute of the State of
Espírito Santo were stimulated by the National Water Resources Policy (Brasil 1997),
as a social and environmental management programs carried out by private companies and public agencies, looking for ways to recycle the water used in buildings or
collect rainwater for use in cleaning, gardening and depletion.
The Municipality of Vitória promulgated in 2007 the Program for the Conservation, Reduction and Rationalization of Water Use in Municipal Public Buildings
with the objective of “establishing measures that stimulate the conservation, rational
use, and use of alternative sources for abstraction of water in new public buildings, as
well as the awareness of users about the importance of water conservation” (Vitória
2007).
Rainwater, although a random occurrence resource, can be collected with the
purpose of meeting some basic demands, and in arid regions, this is an important
source of water for families. Other unconventional sources of water utilization may
be related, for example, to refrigeration appliances. The use of dripping water from
air conditioning equipment has been of major concern in recent years, since the
volume generated daily, regardless the rainfall occurrence, may have less noble uses,
allowing treated water to be allocated for the more important activities.
