36" Round Disappearing Waterfall Base 35 gallon capacity and 6,000lb. weight limit. These very sturdy pondless water feature bases are designed to be buried in the ground and finished with rock or pebbles on top or left above ground and bricked in. They act as reservoirs for the water that recirculates through waterfalls as well as drilled basalt, granite and pots. The water features are placed directly on top of the base, and lid segments allow pump access without dismantling the water feature.
