Abstract
Abstract An improved removable condensate collector for elevated water storage facilities includes a membrane attached to the walls of such elevated water storage facility and positioned to prevent condensate from falling onto structures located at or near the bottom of the facility from a water storage container located at or near the top of the facility. The membrane can be frusto-conical in shape with the apex thereof located above or below the base, or can be horizontally disposed within the facility. The membrane is strengthened to support collected water thereon, until evaporation and ventilation remove that water from the storage facility.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
208 words
An improvement in an elevated water storage facility comprising: a water storage tank supported on top of an enclosed column and a partition extending across the column dividing the enclosed column into an air space above the partition and a work area for offices, warehouses, and the like located beneath the partition with elements located in the work area which can be damaged by condensate falling thereonto from the tank; collecting means for collecting condensed water vapor which drips from the underside of said tank, the collecting means including attaching means mounted on a wall of the enclosed column above the partition, a membrane attached to said attaching means and mounted inside the column at a location between the tank and the partition for collecting any condensate falling from the tank prior to that condensate falling onto the partition; and membrane strengthening means for internally reinforcing and strengthening the membrane to permit water collected on the membrane to be retained on the membrane for a period of time until evaporation and ventilation can remove that collected water from the elevated water storage facility; and ventilation means being disposed with the column and open to the outside atmosphere for facilitating ventilation through the facility to remove said collected water.
Claim 2
Dependent Claim

An improvement in an elevated water storage facility comprising: a water storage tank supported on top of an enclosed column and a partition extending across the column dividing the enclosed column into an air space above the partition and a work area for offices, warehouses, and the like located beneath the partition with elements located in the work area which can be damaged by condensate falling thereonto from the tank; collecting means for collecting condensed water vapor which drips from the underside of said tank, the collecting means including attaching means mounted on a wall of the enclosed column above the partition, a membrane attached to said attaching means and mounted inside the column at a location between the tank and the partition for collecting any condensate falling from the tank prior to that condensate falling onto the partition; and membrane strengthening means for internally reinforcing and strengthening the membrane to permit water collected on the membrane to be retained on the membrane for a period of time until evaporation and ventilation can remove that collected water from the elevated water storage facility; and ventilation means being disposed with the column and open to the outside atmosphere for facilitating ventilation through the facility to remove said collected water.
Claim 3
Dependent Claim
32 words
The improvement in an elevated water storage facility as defined in claim 1 wherein said strengthening means includes a rubberized fabric in the membrane, and said fabric having fabric reinforcing means therewithin.
Claim 4
Dependent Claim
67 words
The improvement in an elevated water storage facility as defined in claim 2 wherein said attaching means includes a mounting base attached by welding to the column wall and having a membrane attaching face spaced radially inward from the column wall, said membrane being attached to said attaching face so that said membrane is attached to said attaching means at a location spaced from the column wall.
Claim 5
Dependent Claim
24 words
The improvement in an elevated water storage facility as defined in claim 3 wherein said mounting base includes means for stiffening the column wall.
Claim 6
Dependent Claim
23 words
