This presentation will summarize the evolution of the plant and detail some of the major changes/improvements thru the years

"We are going to have to scale down our thinking a bit

Investigation of water quality

as well as keeping average insurance rates down

Effective control is accomplished at very low or sub detectable levels of free available halogen

Feedwater for the tower was Boulder city water

and propane

The fill removed during the repack is treated in a transportable facility located on-site close to the cooling tower

New non-metallic heat exchanger technologies allows for a lower cost alternative as well as fouling and clog resistance

System degradation often results
