I'll add a trivial aspect related to design and maintenance of evaporative factory-assembled cooling tower.
- Check and possibly test the drift losses. Some manufacturers guarantee a maximum drift loss. Relative numbers might appear of little impact (e.g. 0.001%), but proper installation and maintenance of drift eliminators can save tons of water in mid-size and large installations.

Drift is easily miscalculated if one only follows the EPA-42 (or is it 142) formula. That formula really is wrong as TDS gets into higher levels, as at the higher residual TDS, there is no way a particle of 10 microns will be formed. Thus the PM10 calculation is completely erroneous. Drift will be represented by the limiting cycles of concentration of the tower.
