We estimate the volume of domestic effluents diluted in water by crossing the data (Sentinel-2 images) with a specific algorithm. With that, we extract the information from the total of domestic effluents diluted in water and maked them available in a websig application to facilitate the management of the analyzed water body. Possibility of rapid analysis of water quality, in addition to measuring the Ecological Footprint related to human activity in drinking water bodies, is an important step towards reducing the costs of treating these waters and thus making them more accessible, especially at such a unique moment, in which water is a resource is extremely necessary.
