The interactive map was built from the responses to the questionnaire on access to water in precarious housing, applied between May 4 to June 4, 2020.

The questions were asked in order to understand the conditions of access to water, perceptions of the continuity or intermittency of supply and the situations faced during the pandemic.

The information was geo-referenced, and is available on an interactive map along with other important layers to think about the issues of access to water and its relationship with infrastructure, zoning, the environment and the right to the city.

In 2020, the project was covered by the CARTO platform with a license to build the interactive map.
