Brine ponds are a specialized type of pond that feature a variety of different uses. Primarily, they are useful as specialized storage or containment systems to either store or process brine. They are common in the energy industry for a variety of different purposes, in the desalination industry, and sometimes in manufacturing, particularly as a means to manufacture salt.
These ponds require careful construction. It is imperative that they are lined with a reliable liner to prevent leaks that can contaminate local aquifers. To that end, brine ponds are typically double lined systems that feature a geosynthetic drainage layer between the liner layers. This drainage layer acts as a sponge to capture any leaks, and it also makes it easier to monitor the pond for leakage.
