Brine ponds are fairly static elements, so it seems like they may not require much in the way of maintenance, but since the material they hold is potentially so damaging, that’s a dangerous presumption.
Evaporative brine ponds are designed to lose water over weeks or months, gradually reducing volume. This means that a significant percentage of the topmost liner will be exposed to direct sun for long periods of time. If it’s a liner with high resistance to solar radiation, that’s been considered, but it’s still necessary to inspect the ponds regularly to ensure there has been no unexpected damage that could compromise the pond’s containment. Liner weakened by exposure to the sun may be more vulnerable from tears or punctures from debris carried in by the wind during a storm event, for example.
Aside from sunlight and possible damage from outside elements, there is significant wear and tear involved in daily use. Consider the use of heavy equipment to remove minerals, salt and other materials from the sides and bottom of your pond. The mineral crystals themselves that have formed have sharp edges and friction can contribute to weak spots and tears. If a low-quality liner is used, the growth of algae or other plants can weaken the liner and allow it to tear even during the first harvest. Any kind of cleaning activities cause wear on any type of liner.
Liners, pipes, leak detection equipment and secondary containment structures require regular checks for structural integrity and proper function. Any questionable areas should be carefully examined and either repaired or replaced without delay. Once damage begins, it is likely to multiply, and any escape of brine represents an immediate emergency.
