2. Pond liner - Wikipedia

   en.wikipedia.org/wiki/Pond_liner

   Pond liners need to be protected from sharp objects (for example, stones) below the liner and from being punctured by any objects in the water body. Protection can be provided with layers of sand, geotextiles (particularly needle-punched nonwovens) and other materials. Pond liners are manufactured in rolls or accordion-folded on pallets.

3. Evaporation pond - Wikipedia

   en.wikipedia.org/wiki/Evaporation_pond

   Each pond liner is prone to leakage and requires regular maintenance. [2] The contents of the evaporation pond depend on the use, the evaporation pond will contain water and the desired contents hoping to be extracted. The desired contents range from waste to minerals, and the remaining contents are either stored or extracted. [2]

4. Electrical liner integrity survey - Wikipedia

   en.wikipedia.org/wiki/Electrical_liner_integrity...

   Since the arc testing method is not dependent on water making good contact through the leak, it is more sensitive and comparatively easy to perform in most types of liner construction (ponds, Landfills, tanks etc.)than the water-based methods. The minimum sensitivity of the arc testing bare geomembrane liner integrity method is a pinhole leak.

6. Pond - Wikipedia

   en.wikipedia.org/wiki/Pond

   A pond is smaller than a lake [1] and there are no official criteria distinguishing the two, although defining a pond to be less than 5 hectares (12 acres) in area, less than 5 metres (16 ft) in depth and with less than 30% of its area covered by emergent vegetation helps in distinguishing the ecology of ponds from those of lakes and wetlands.

7. Cooling pond - Wikipedia

   en.wikipedia.org/wiki/Cooling_pond

   At the 89 MW Back o’ the’ Bank power station in Bolton UK the cooling water was cooled in 4 spray ponds. [12] The small size of the spray droplets improved the heat transfer, increased evaporation, and led to more effective cooling. Each cooling pond had a capacity of 0.75 million gallons per hour (0.95 m 3 /s). [12]
