Dear student,
In such cases, scientists would try to find a balance between the amount of water needed for drinking and water needed for fuels. Also greater emphasis would be laid on rainwater harvesting and preventing runoff of rain water to seas and oceans. Also there are ways of converting sea water into drinking water through reverse osmosis. So drinking water would be available to all.
