The water can come from the Canal du Midi, the river, the city or the recovery of rainwater. In all cases, it is necessary to adapt a treatment adapted to the quality of the water.
The installation of a filtration system makes it possible to use water for toilets, washing machines, bathrooms and kitchens. For drinking water, it will take a water purification system with ultraviolet sterilizer to ensure the best possible quality.
For bacteriological problems, it is sometimes better to carry out ultra-filtration for the entire barge, in order to guarantee optimal quality.
