We have designed a 40-litre water tanker, which is placed on the tractor of the trucks that allows space to be optimised and that drivers can have sanitary water available without having to resort to bottles, drums, etc. or other types of impractical containers, which do not fit in the trucks or are disposable. We are very committed to the environment and every drop of water counts, so the water tank remains in the tractor of the truck, regardless of the load, so the drivers can change the load and always have the tank available. Although it may seem like a minor thing, having a permanent water tank is essential for drivers, many times it is synonymous with discomfort, anger since we are facing a primary need. We have detected that having such a basic need covered, makes drivers less stressed at this point, reducing the peaks of anger, stress and frustration caused by the simple fact of not having to wash their hands, face, after having to load, unload, fix the truck, etc.
