Abstraction of water from Northern Welifield was achieved by pumping from twenty-eight production boreholes, including two stand-by boreholes, equipped with submersible pumps (Figure 1). The total abstraction for the monitoring period amounted to 9 134 206 m3, representing a slight increase of 2.3 per cent from the previous reporting period ( 1 January 2000 - 31 December 2000 ) figure of 8 929 220 m3 (Table 1.) The increase in abstraction I can be attributed to the commissioning of the new slimes dam No.7.ย
