The availability of drinking water remains a problem in the department of Gossas - both for production and sanitation needs and especially for human consumption. These difficulties are linked to its quantity and/or quality. In some places, groundwater contains solutes that are not suitable for consumption, making it brackish.
Inhabitants of the region, who use the water from the borehole, were affected by illnesses linked to the poor quality of the water because it contains dissolved substances that affect human health.
The solution was to install rainwater tanks and treatment systems - ultra-violet purifiers that make rainwater fit for human consumption.
