The study, in general terms, sought to develop a methodology that could contribute to a
better decision making regarding the implementation of alternative water supply solutions in
rural areas. Since these seek to provide access to potable water to rural dwellers, from the
assembly of small alternative stations; reduce and / or eliminate water consumption directly
from the river, which is often polluted and / or contaminated; better health conditions for the
population. Through this work, the costs involved in the implantation were raised using the
combined technique proposed by Tietenberg. Based on knowledge based on information
available in the literature, effectiveness indicators were proposed in five dimensions of
analysis and evaluation (social, operational, environmental and institutional political). The
dimensions were based on those proposals in the literature for sustainable development
analysis. And the selected indicators, in number of nine, were constructed using the
theoretical scope from the studies developed by Dias and Guimarães. The methodology was
applied to four alternative supply solution projects and the results were obtained from the
cost x effectiveness ratio. It was found that the 'Hybrid' alternative solution is more cost
effective in most scenarios, however in some scenarios it is necessary to apply a more
weighted analysis to guarantee the efficiency in the implementation of alternative solutions.
The proposal and the results obtained are relevant to enable decision-making mechanisms
for the feasibility and financial application of water supply projects that guarantee access,
quality, quantity, security and sustainable development to rural communities.
