Vianti Falls Extended Lip Spillway 35 1/2''

35 1/2 inch extended lip waterfall spillway options like the Vianti Falls Extended Lip Spillway are designed to push the water sheet outward, helping you create a cleaner, more dramatic waterfall even when wind or backsplash would normally disrupt the flow.

This 15" extended lip design projects the waterfall away from the vertical surface, making it an excellent choice for larger pondless or pond features, retaining-wall builds, and custom masonry waterfalls where you want the water to clear the face of the wall. The extended lip also helps reduce water tracking back along the structure, supporting a more consistent, uniform spill.

Key benefits

• Built for challenging installs: Ideal for windy locations where a standard spillway can blow back onto the wall.
• Bold visual impact: Creates a wide, dramatic water sheet for statement features.
• Custom-build friendly: Integrates into masonry, block, or stacked-stone waterfall designs.
• Multiple 1" inlets: Supports higher flow distribution for wider spillway coverage (see model specs below).
