To maximize reuse, operators must carefly manage water chemisty to prevent scaling and corrosion in steam generators.

Reuse also reduces costs associated wigh freshwater indestition, transportation, and disposal. A typical SAGD facility may save tens of million of dollars annually by cutting freshwater imports by 50- 70%. These savings can partly offset thee capital andd operating fresses of advanced water treatment systems.
