Abstract: A water capture device for installing in an elevated location on a building. The water capture device comprises a plurality of exterior walls, an input opening, a main chamber, a release opening, an overflow channel, and an overflow opening. The plurality of exterior walls defines a cavity. The input opening allows for allowing water to enter the cavity. The main chamber is within the cavity configured to fill with water. The release opening is for selectively releasing water from the main chamber for use by a user. The overflow channel within the cavity is for receiving excess water from the main chamber that rises above a threshold associated with the overflow channel. The first overflow opening is for allowing excess water within the overflow channel to freely exit the water capture device.
