International Classification:

B04H 400

US Classification:

4507

Abstract:

An artificial waterfall apparatus and method for providing a sheet-like waterfall at the edge of a pool, spa, or fountain, for example, includes a first elongate chamber into which water flows perpendicularly to the length of this chamber, and in which a pair of oppositely directed like-rotating helical recirculation water flows are formed to sweep air and debris to opposite ends of the first chamber, while also contributing to uniformity of water distribution, pressure, and flow velocity in the apparatus. Air is discharged from the apparatus near one of the opposite sides of the waterfall so that the main central body of the waterfall is not disturbed by air bubbles. A second chamber receives water flow from the first chamber, and includes a flow distribution member which further contributes to uniformity of water flow in the apparatus. The apparatus has features which promote desirable structural strength in its use environment, and features which assist drainage of the apparatus for winter-time non-operation free of a damage risk from freezing.
