In 2005 total water withdrawal was estimated at 81 million m3 of which 54.8 million m3 (68 percent) for agriculture, 20 million m3 (20 percent) for municipalities and 6.2 million m3 (26 percent) for industries (Table 3, Figure 1 and Figure 2).
BWA currently supplies approximately 58 million m3 of water per year. Its water supply network comprises 2 spring sources, 22 wells, 8 boreholes, 27 reservoirs and 14 re-pumping stations scattered across the island (BWA, 2014). There are also some 120 privately-owned wells, most of which abstract water for irrigation purposes.
In 2000, groundwater accounted for 98.6 percent of the public water supply (MPDE, 2001).
