On 31 January 2020, the WHO declared the COVID-19 outbreak a Public Health Emergency of International Concern (WHO, 2020). In Brazil, the city of São Paulo, the richest capital in the country, was the epicentre of COVID-19 cases.  In the pandemic context, some measures addressed to people in street situation were intended to minimize the risk of transmission of the disease (GARCIA et al. 2020). Among these measures, the installation of community sinks and drinking water fountains were carried out, whose location was places to outreach this specific population who lives in streets. Yet these set of actions has been important to lower the impact of the COVID-19 transmission on this population, some other aspects must be studied related to health risks prevention due to the multi-usage of these devices such as water- and foodborne diseases. Thus, for improving these actions and to promote health we must consider to verify the quality of the water distributed by these devices. Right now, our aim is to design a plan to evaluate the microbiological quality of water from these devices.  Firstly, we set criteria for selecting public water distribution devices according to their location in the city, circulation of people and the number of device users and, also their level of social and health vulnerability. Further, we will carry out the assessment of drinking water quality has based on the Brazilian legislation for water potability (BRASIL, 2021). There were nine points that were selected for a one-year followed up. In addition, it has been carried out a photographical exploration of the use of the devices with the authorization of the users. The study, is still under development but we observed a variety of usages. Preliminary data indicate that these public facilities are essential for the population, but not sufficient for health promotion.
