200,000 gallons of water for each unit, pumped continuously between turbine condensers and cooling towers, are used every minute to convert the exhaust steam from the turbine back into water for reuse. The circular, mechanical draft towers, 300 feet in diameter and 75 feet tall cool the water used for this conversion. This is accomplished by thirteen 200-horsepower foot fans drawing air through the sides of the towers to cool the water for reuse in the condensers. Water from Lake Michigan is
used to replace the 3,000-4,000 gallons of water lost every minute
through evaporation from each tower during the cooling process.
