Typically, an evaporation pond will require a chemical resistant geomembrane liner. The specific type of liner depends on the geographical location of the pond and the purpose for which the pond is constructed. Clay was originally used to line evaporation ponds, but there are distinct disadvantages to clay liners. The material is heavy, difficult to transport and install, and can be prone to cracking. Clay liners are costly, and they also require ongoing, consistent maintenance. Multi-layer, flexible, reinforced pond liners are lighter, easier to transport and install, and they require very little ongoing upkeep. They are designed to protect groundwater, and a dark top layer, typically High Density Polyethylene (HDPE) with a LDPE engineered dark coating, actually enhances evaporation of the water contained in the ponds.
These multi-layer liners have been engineered to be tear and puncture resistant, which reduces the risk of adverse environmental impact, and they may be doubled for extra strength and protection. A multi-layer RPE liner is not only economical, but it is easy to install, requires little or no maintenance over the long term, can last for decades, and is UV resistant. It is engineered to provide maximum safety for containment of toxic byproducts, and it is available in a variety of configurations to meet specific design needs.
