Which vehicle do Fleet Service personnel use to service the aircraft potable water system?

Fleet Service personnel use a Potable Water Truck (PWT) to service the aircraft potable water system because this vehicle is specifically designed for safely transporting and delivering potable water to aircraft. The PWT is equipped with a system that ensures the water meets health and safety standards, preventing contamination and guaranteeing that the water being supplied to the aircraft is clean and suitable for consumption.

In addition to transporting water, PWTs often have features such as tanks that are lined with materials that prevent leaching of toxins, hoses with fittings that maintain sanitary conditions, and other mechanisms that make the process of delivery efficient and compliant with regulations governing potable water systems in aviation.

While other vehicles like the Water Service Vehicle could informally refer to a similar function, the term Potable Water Truck is the recognized terminology in aviation for this specific purpose, ensuring clarity and adherence to industry standards.
