In 2003 total water withdrawal was 12.3 million m3, of which agriculture accounted for only 7 percent (Table 3 and Figure 1). Most of the agricultural, municipal and industrial waters come from small streams or rivers from the hillsides, depending on monsoons and the rainfall pattern. The abstraction of surface water amounts to around 11.2 million m3/year (2003) and of groundwater to 0.3 million m3/year (2003.) The principal groundwater abstraction is on la Digue Island for municipal and agricultural consumption.
