Abstract: A system and method to create or elevate a berm of a liquid retention facility by placement of lightweight fill material anchored by impervious liner material(s). The liner materials can be part of the liquid retention pond. The system and method can also be used to elevate the height of the berm in combination with impervious liner retention material. By constructing the berm system on an existing berm, earth embankment or levee, the effective height of the system structure can be increased. The liquid impervious liner material provides a watertight surface, joining media, and the anchoring of the lightweight fill material to the existing berm. The system may use solid wall hollow body structures. The system may also use flexible and liquid porous geotextile structures including geotubes. The liquid impervious liners retain the liquid in the retention pond.

The system may use solid wall hollow body structures to elevate the berm. The system may also use lightweight frames to support the vertical elevation of a liner above the berm.
