CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Application No. 60/688,412, filed on Jun. 8, 2005. The disclosure of the above application is incorporated herein by reference. FIELD OF THE INVENTION [0002] The present invention relates to water pump assemblies. More particularly, this invention relates to a portable high volume water pump assembly for use in fire fighting operations. BACKGROUND OF THE INVENTION [0003] In emergency situations, such as when a building, vehicle or other large object catches fire, a matter of seconds determines not only whether the object is a total loss, but whether lives could be at risk. It is therefore imperative that personnel trained to put out the fire arrive on the scene as quickly as possible. Furthermore, they must be provided with the proper extinguishing supplies with which they use to sequester the fire, such as water. Many rural and even urbanized areas of the world are not outfitted with a constant supply of pressurize water with the dedicated purpose of extinguishing fires such as fire hydrants. [0004] Alternative sources therefore must often be used in order to battle many of these fires. One such example is a mobile tank mounted on a vehicle such as a fire engine for supplying the water. Unfortunately, these carry a very limited volume in which they can transport, are not always available in every community, and therefore may not provide the amount of water necessary to fully put out a large fire. Local sources of water such as swimming pools, ponds, or lakes have the potential to be a great source of water for fighting fires, but providing a means of getting the water out of the pool or pond and onto the fire in the very swift manner and in sufficient volume necessary to salvage the burning object proves difficult. Therefore it would be advantageous to have a portable and submersible means of pumping the water out of theses sources which can quickly be implemented in an emergency situation, and provide the fire fighters with a supply of water having high enough pressure and volume to quickly tend to the fire. SUMMARY OF THE INVENTION [0005] It is therefore an object of the present invention to provide a portable, hydraulically powered water pump useable for situations such as fire fighting and industrial dewatering. [0006] Another object of the present invention is to provide a portable pump that is used in conjunction with a boom arm of a utility or firefighting vehicle, for placing the pump in a supply of water some distance away from the vehicle. [0007] Another object of the present invention is to provide a portable high volume water pump which can be utilized in a water source such as a pond, pool, or on municipal pressure hydrants to boost output pressure. [0008] Still, a further object of the present invention is to provide a portable, high volume pump which may be utilized in a water source having as little as two inches of water depth. [0009] It is a further object to provide a pump that is simple in design and manufacturability and can be utilized in a plurality of applications. [0010] These and other objects will be understood wherein the present invention discloses a portable, fully submersible high volume water pump, driven by a hydraulic powered motor, for rapidly supplying a large volume of water to an extinguishment operation involving a burning object or building, from a local water source such as a pond, pool, portable basin or municipal hydrant. The pump is fully portable and protected within an attached housing. In a preferred embodiment, it may be used in conjunction with an extensible boom arm of a utility vehicle such as a fire engine or other utility truck. The water pump is run from a vehicle mounted or portable pressure compensated load sensing hydraulic system, allowing for variable flow and pressure, and can supply water from a source having as little as two inches of water depth. The volume of water deliverable from the present invention is comparable to that delivered from a fire engine pump itself and may be utilized to directly extinguish or refill a supply of water on a vehicle for subsequent use. [0011] Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention. BRIEF DESCRIPTION OF THE DRAWINGS [0012] The present invention will become more fully understood from the detailed description and the accompanying drawings, wherein: [0013] FIG. 1 illustrates a perspective view of the preferred embodiment comprising the water pump, coupler, and hydraulic motor assembly; [0014] FIG. 2 is a side view of the assembly shown in FIG. 1; [0015] FIG. 3 shows an end view of the water pump assembly comprising the intake strainer and discharge tube; [0016] FIG. 4 illustrates a cross sectional view of the coupler assembly with splined drive shaft of the present invention taken along line 4 of FIG. 2; [0017] FIG. 5 illustrates a side, phantom view of the water pump assembly within the pump housing body; and [0018] FIG. 6 is a partial side-view of the pump assembly in combination with a boom of a utility vehicle.
