Abstract

A water tank for a fire truck constructed of a foam and fiber glass composite material. The tank is generally rectangular in shape and has two large compartments, one being at the front and the other being at the rear of the tank. The front compartment has two access doors provided in the left side panel and in the right side panel respectively of the tank. The rear compartment has five access doors, three doors being provided in rear panel and two doors being provided in the side panels of the tank. A gated dump valve for dumping the water in the tank is also provided. The valve has a gate that is used to control the direction of flow of the water being dumped from the tank. Depending on the position of the gate water will flow either from the rear of the truck or from the side of the truck. Provision is made for both the opening and closing of the valve and the changing of the gate position to be controlled from inside the cab of the truck.
