Problems of water supply are becoming more frequent, mainly due to population growth with increased demand on water consumption and pollution of water resources, factors that may also be indicated as the main aggravating the scarcity of quality water. Within this context there is clearly a need for some measure to alleviate this situation, as the search for alternative sources of water. The use of rainwater is shown as an effective alternative for the supply of domestic demands for water and reduce dependence on supply companies. This paper presents a study of rain water catchment, since it is an important and abundant resource and it can help in solving problems related to public water supply, which is deficient in some regions of the country. The rainwater usually has good quality with low levels of dissolved and / or suspended materials, requiring a more simplified than the conventional one to make it drinkable. The aim of this paper is to analyze the rain water quality and the potential of use for the municipality of Florianópolis. The methodology comprised physical-chemical and bacteriological analyzes of rainwater collected directly from the atmosphere and after passing through a roof to evaluate the quality of rainwater. A historical series of precipitations of the municipality was used to evaluate the potential of use. The results of the analyzes showed that the rainwater in Florianópolis presents satisfactory quality in relation to the parameters analyzed. The catchment area was shown to be a factor that causes degradation in rainwater quality. The municipality presented satisfactory potential for the use of rainwater, since rainfall is frequent during the year and with a considerable volume.
