Cooling Ponds

Cooling ponds are shallow reservoirs with large surface areas for removing heat from water. They’re used to allow heated water from factories or utility plants to cool to the same temperature as nearby bodies of water so it can be (a) discharged without causing harm to fish or plant life, (b) recycled for plant use, or © treated further if it is contaminated as well as elevated in temperature. The liner material must be UV, tear and puncture resistant and it must be able to hold up the range of temperatures to which it will be exposed.

This pond, at the Brazos Electrical Power Co-operative’s thermoelectric power generating plant, holds cooling water. Cooling water condenses the steam that has been used to spin the turbine-generator back into water. The condensed water is pumped back into the steam generator to become steam again, while the cooling water is sent to the cooling pond, allowed to cool, then reused. 300,000 square feet of PetroGard VI material was used based largely on it’s ability to hold up to years of exposure to extreme temperatures. Deicing fuel liners have extreme temperature requirements, but at lower temperature ranges.
