86-02: An Operations History of W.A. Parish Units #7 & #8 Main Cooling Towers Environmental Impact Periodic inspections of mechanical andThe limited cooling capacity of the HL&P W. A. Parish lake made the construction of cooling towers essential with the last two generating units. The operations history of these two large, round, concrete cooling towers is reviewed. In addition to comparing their design similarities and differences, specific areas are discussed, including the dual sources of makeup water and blowdown control.
