Abstract: The rate of evaporation in an evaporation pond containing contaminated produced or process water from a hydrocarbon production operation is increased by pumping water from just beneath the surface of the pond through a pipe extending around the periphery of the pond. The water is dispensed around the periphery of the pond from ports in the pipe and then trickles down into the pond water. The pond has a black plastic lining, with a border region that is not submerged. The water from the pipe trickles down across the un-submerged black lining that is at an elevated temperature due to radiative solar heating, and energy is thereby imparted to the water to increase the rate of evaporation.
