Water is life.
The majority (94%) of the earth’s water lies in oceans, which is salt water and 4% is frozen.
The remaining 2% is fresh water, which is available to man for drinking, hygiene, and industrial use. It is clear that fresh water is scarce and it has to be managed with all skills available to man. One of these skills is to build and manage efficient water supply infrastructure, which will ensure the social upliftment of all mankind.
This is the market Mercury Inter-Trade focuses on.
