"Real and Apparent Losses", which is the difference between <br />produced water (leaving the water treatment plant) and all metered water deliveries, <br />accounted for an average of 10.1 % of total water produced annually for the 2000 <br />through 2006 period. "Real and Apparent Losses" include both real, or physical, losses <br />as well as apparent, or paper, losses. Real losses include water lost to system leaks or <br />tank overflows. "Apparent" losses may be due to meter, billing, or accounting <br />inaccuracies and may include authorized uses such as for fire suppression or <br />construction activities.
