There is more than enough freshwater on the planet to meet the needs of all people. Nevertheless, one in nine people worldwide still has no access to clean drinking water. Technology plays a crucial role.
Drinking water scarcity
Population growth, changing lifestyles, and urbanization only make the inadequate supplies of safe drinking water in short supply even more. By 2030, people will only have enough drinking water supplies to satisfy about 60 percent of the global demand. In numerous developing countries already struggling with scarcity of freshwater, the supplies will provide less than 50% of demand. Undoubtedly, there is no magic bullet however technology has a very crucial role to play. Water-efficient plants, waterless toilets, and ingenious water purification systems could play an important role in guaranteeing that every person gets access to the water he needs.
Technology can transform seawater into safe drinking water
With an increasing population of about 14 million, the capital of Karachi, Pakistan has been faced with an increasing demand for drinking water from its primary source, the Indus River. One of the leading housing authorities in Asia in 2000 started an international hunt to look for a remedy that would give a new supply of safe drinking water. Thus, DHA Cogen Ltd has been made as a joint project between the Sacoden Investments of Singapore and the Defence Housing Authority of Karachi.

DCL has started and installed the first co-generation plant in Pakistan to make both potable water and electrical power. They opt to make use of Alfa Laval technology in order to solve its drinking water problem due to the ground-breaking desalination process which turns the seawater into fresh drinking water. The plant uses waste heat based on the concept of co-generation from one piece of machine to run another piece of machine.
In addition, because the plant has a very big intake of seawater as compared to the output of freshwater, the water being returned to the sea holds a salt concentration which is low enough for the seabed and the marine life in the area to be safe. And it normalizes the water temperature making sure that it is not harmful to the marine environment.
