Despite this abundance, the water resources availability is not properly distributed amongst the islands and geographical regions. Meanwhile, population distribution is also unbalanced having over 60% of the country's population are concentrated on Java Island alone, which is in fact, consisted only about 7% of the total land area of the country. The total water resources potency of Indonesia is estimated at about 2,530 krrr', of which only about 2% (96 m3/capita/year) is currently utilized for different purposes. Out of the 2% of the current water utilization, about 76% is currently used for supporting agricultural activities, 13.5% for domestic water consumption, and 11.5% for industry. Water distribution by island for the . most part is concentrated on three major islands.
