Abstract
Abstract An outdoor water holding and pumping system comprising a water tank into which is recessed a pump housing such that water in the tank surrounds and insulates the housing. A pump is disposed in the pump housing for pumping water from the tank to a desired location. The pump housing has a door providing access to the pump from outside the tank. The system preferably includes a housing conduit which extends from the housing to the base of the tank so that conduits to and from the tank can extend underground, through the tank, and to the pump without being exposed. Reserve conduit means are also preferably provided to provide a reserve supply of water to the pump. The system elements are preferably connected for transporting as a unit.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
191 words
An outdoor water holding and pumping system for remote locations comprising: a water holding tank having upper and lower portions including an interior, an exterior and a water containing surface; a pumping housing having side walls, a bottom and a top recessed into said lower portion of said tank, said side walls, bottom and top substantially surrounded by and in relation to water in said water holding tank such that water in said tank insulates said pump housing against freezing; a water pump disposed in said pump housing and having an inlet conduit extending through said pump housing to the interior of said tank, said inlet conduit having an inlet opening through which water in said tank is drawn by said pump, said inlet opening residing above said bottom of said pump housing such that when water in said tank falls to the level of said inlet opening, water in said tank still acts to insulate said pump housing and water in said pump against freezing; and a door enclosing said pump within said pump housing and providing access to said pump through said door from the exterior of said tank.
Claim 2
Dependent Claim
191 words
An outdoor water holding and pumping system for remote locations comprising: a water holding tank having upper and lower portions including an interior, an exterior and a water containing surface; a pumping housing having side walls, a bottom and a top recessed into said lower portion of said tank, said side walls, bottom and top substantially surrounded by and in relation to water in said water holding tank such that water in said tank insulates said pump housing against freezing; a water pump disposed in said pump housing and having an inlet conduit extending through said pump housing to the interior of said tank, said inlet conduit having an inlet opening through which water in said tank is drawn by said pump, said inlet opening residing above said bottom of said pump housing such that when water in said tank falls to the level of said inlet opening, water in said tank still acts to insulate said pump housing and water in said pump against freezing; and a door enclosing said pump within said pump housing and providing access to said pump through said door from the exterior of said tank.
Claim 3
Dependent Claim
92 words
The system of claim 1 which further comprises: a reserve conduit connected to said inlet conduit and having a reserve conduit opening disposed in said tank beneath said inlet opening; and valve means for regulating the flow of water through said inlet conduit and said reserve conduit to said pump such that a reserve quantity of water in said tank between said inlet opening and said reserve conduit opening can be selectively conveyed to said pump by operation of said valve means when water in said tank falls below said inlet opening.
Claim 4
Dependent Claim
50 words
The system of claim 1 wherein said water-containing surface has a ground-engaging base portion and which further comprises: exterior conduit means for conveying water from said pump to a desired exterior location, extending from said pump through said housing and said base portion and underground to a desired exterior location.
Claim 5
Dependent Claim
71 words
The system of claim 1 which further comprises: housing conduit means sealingly extending from said housing through said interior of said tank to said water-containing surface; exterior conduit means for conveying water from said pump to a desired exterior location, extending from said pump through said housing conduit means to a desired exterior location; and power supply means for powering said pump extending from said pump through said housing conduit means.
Claim 6
Dependent Claim
36 words
The system of claim 4 wherein said water-containing surface has a ground-engaging base portion and wherein said housing conduit means sealingly extends from said housing through said interior of said tank to said ground-engaging base portion.
Claim 7
Dependent Claim
60 words
The system of claim 1 which further comprises: an exterior water supply conduit disposed in said pump housing for conveying water from an exterior water supply to said interior of said tank extending through said pump housing to said interior of said tank; and water inlet valve means for regulating the flow of water through said exterior water supply conduit.
Claim 8
Dependent Claim
29 words
The system of claim 1 wherein said tank, said pump housing, said pump and said door are all connected for being transported as a unit to a desired location.
Claim 9
Dependent Claim
31 words
The system of claim 1 wherein said pump housing is disposed in said tank such that said pump housing is completely surrounded by water in said tank, except at said door.
