Resumo
Analysis of the quality of investments should be part of decision-making for
implementing rainwater-harvesting systems in order to evaluate whether
investments in environmental impacts mitigation are also attractive from
the point of view of investors. Considering discounted cash flow methods,
net present value is the best indicator for this analysis, because it allows
deciding which is the best between two mutually exclusive projects, and
it also presents a simple calculation routine and is easily understood by
users. This work aimed at presenting a decision-making analysis tool for
rainwater-harvesting systems, which is based on the maximization of
net present value, using the Particles Swarm Optimization technique.
The decision tool was used to evaluate the quality of the investments for
implementing a rainwater-harvesting system, considering a building of
the public tax category. Three scenarios of the water bill were considered:
current rate structure and increases of 100%, 150% and 200%. All scenarios
contemplate two alternatives: with sewage rate corresponding to the
rainwater use and no fee. Results illustrate opportunities for investments in
rainwater-harvesting systems.
