Shum Chun and Indus River Water
10.07. It is normal to stop pumping from the Shum Chun Reservoir as soon as summer rains can be expected to fill the Tai Lam Chung Reservoir but this condition did not arise and all water available was received. The considerable increase in water extracted from the River Indus compared with previous years was made possible only by moving pumps which could be spared from other locations and erecting them at the Indus. Pump movements which took place are indicated below.
