This type of vehicle is used for the transport of drinking water or industrial water, for washing and spraying roads as well as for watering green areas.

The basic element is the tank, which is located parallel to the undercarriage of the vehicle. It is made of stainless steel in a circular shape, cube-shaped with curved edges and elliptical shape, with a volume of 4m³ to 16m³.

The tank is divided into smaller chambers inside to prevent water from colliding with the walls. The filling is done through an opening in the top of the tank, and emptying through pumps.
