Claims: I claim:

1. A container for reducing water consumption during the flushing of a water closet having a water inlet valve at one end and a water output valve at the center, said container comprising a pleated hollow and substantially rectangular prism made of impervious flexible material and having the pleats thereof disposed in vertical planes between ends of said container, and an aperture formed at the top of said container to enable water to fill the container when it is placed in said water closet on the bottom thereof with said pleats partially compressed to enable its installation between front and back walls of said water closet at one end thereof remote from said water inlet valve without interfering with operation of the water inlet valve or operation of said water outlet valve said pleated container having a demension in a direction normal to the plane of said pleats greater than the distant between said front and back walls to require said pleats to be compressed upon installation of said container, whereby the partially compressed pleated walls will hold said container in place as said water closet empties out and refills during a flushing operation.

2. A container as defined in claim 1 including an aperture formed in a wall and below the top of said container to permit discharge of a small amount of water therefrom during the flushing operation thereby to prevent stagnation of water in the container.

3. The combination as defined in claim 1 including a vessel comprising a hollow and substantially rectangular prism, said vessel having a height greater than width and a length greater than the height, where said vessel height is at least equal to the height of said container to permit said vessel to be placed between said container and one wall of said water closet with said length parallel to said one wall of said water closet, and an aperture formed at the top of said vessel to enable water to fill the vessel.

4. The combination as defined in claim 3 including an aperture formed in a wall and below top of said container to permit discharge of a small amount of water therefrom during the flushing operation thereby to prevent stagnation of water in the container prism and an aperture formed in a wall and below the top of said vessel to permit discharge of a small amount of water therefrom during the flushing operation thereby to prevent stagnation of water in the vessel prism.
