The cost of converting sea-water into acceptable drinking water is very high. Our focus is to make use of our freshwater resources.
But yes, we have been considering the impact, especially, as you said, since 70% of our population lives in coastal areas. With climate change, the sea level is rising. We have been considering how that rise in sea level is impacting our groundwater wells, which are being used as a source of drinking water in coastal communities, because that raises the issue of saltwater intrusion. We are trying to develop policies so that we can optimize the pumpage of water in order to minimize the pumpage of salt water into those wells.
This is an aspect that has been looked into and that has been both modelled as well as monitored, but we have not looked into using sea-water as a source of drinking water for cost-benefit reasons.
