Groundwater use. Groundwater contributes 14 percent of the total water resources potential of the Philippines; groundwater recharge or extraction potential is estimated at 20,200 mcm per year. Northern Mindanao has the lowest potential source of ground water compared to its surface water potential; while Ilocos and Central Visayas have the highest potential. About half the population uses groundwater for drinking purposes.
According to 2003 data, 63 percent of groundwater is consumed by the domestic sector, and the remaining is shared by agriculture (17 percent), industry (13 percent), and other sectors (7 percent). In terms of sectoral demand, agriculture has the highest demand, 85 percent, while industry and domestic sectors have a combined demand of only 15 percent.
