Thus determine the useful volume for use in potable use or non-potable activity is necessary. There are methods for rainwater tank sizing, some being established by standards in use and widely used designs, and other dimensions that are alternatives. The city of Curitiba and other Brazilian capitals are aware of laws which require new buildings over 500 m2 deployment of rainwater systems. The reservoir design seeks to present the useful volume necessary taking into account the rainfall and financial analysis of the implementation of these systems, which also takes into account the water consumption rates fo r public supply.
