The savings graph shows the monthly water usage of the cooling tower on the previous water treatment program versus the Terlyn Conservation Program. Due to the high quality potable water in from Denver Water, the previous water treatment program was able to maintain 5 cycles of concentration.
The water savings potential for a building this size is much greater in most other areas of the country that have lesser quality potable water. With normal potable water quality, traditional water treatment programs usual maintain an average of only 3 cycles of concentration, which requires 13% more waste than at 5 cycles.
