The estimated potential water saving as result of water loss interventions in the study area is 17.7 million
m 3 /a (16.5 million m 3 /a + 3.22 million m 3 /a). It is estimated that the potential saving through improved water
use efficiency could be as high as 7.65 million m 3 /a. The following table illustrates the impact of
implementing a water loss intervention to reduce the current UAW from 41% to 17%.
