Atlantic Water Gardens has finally simplified the design and installation of water walls and water curtains. The WaterWall Spillway is an attractive, enclosed weir that distributes water onto any vertical fascia. Set the WaterWall on top of any masonry or wood-framed wall and plumb it to a pipe hidden inside the wall. With enough clearance between the inlet and outlet to handle any fascia up to 2 inches thick, the WaterWall Spillway delivers a smooth, evenly distributed sheet of water across 24 inches of sloped or vertical wall. Set multiple units end-to-end to create water walls of any width in 2-foot increments.
