Population and industrial growth contributes to the swelling of cities, with increased contamination of rivers, lakes, dams and their tributaries, bringing problems related to the consumption and use of water and its scarcity in Brazil and worldwide. As well as the irrational use of treated water by the Brazilian population in domestic activities such as washing pavements, vehicles, irrigating plants and grass, among other ways, saturating the Brazilian basic sanitation system.

Faced with the need to supplement water for domestic purposes and/or consumption as drinking water, the search for a solution, such as the installation of reservoirs in urban and rural homes that use rainwater and capture it, is an alternative for the survival of the Brazilian and world population. Thus, the aim of this study was to focus on this segment, due to the need to know the profile of consumption of treated drinking water, as well as the use and implementation of the cistern system for storing rainwater in this region, with complementary microbiological and physical-chemical analysis, as well as the rainfall profile over the last five years.
