8.58. The year brought with it the opportunity to dewater the Plover Cove Reservoir for the second time and for this purpose, the capacity of the floating pumping station was increased from forty million to eighty million gallons per day. The dewatering operation was successfully carried out. This plant was later removed and brought ashore for storage following the commissioning of the permanent pumping plant at Tai Mei Tuk.
8.59. A temporary cross-connection made at Tai Po Tau enabled the standby element of the pumping plant installed for the local supply to the Sheung Shui/Tai Po area to be used for delivering extra water to the Sha Tin Treatment Works.
8.60. Subsequent to the commissioning of the new electrical salt water pumping station at Central Reclamation, the old diesel powered pumps at Blake Pier and Rumsey Street were dismantled and removed.
8.61. Four diesel engine pumping sets were temporarily installed to add 12 million gallons per day to the pumping capacity at the River Indus Pumping Station so that the amount of water pumped from China to the Tai Lam Chung Reservoir would not be affected by any breakdown of the existing high lift pumps.
8.62. Maintenance programmes introduced during the year 1967-68 were revised in the light of experience. The in-service training of instrument mechanics and trade apprentices continued.
New Works
8.63. Six new pumping stations were commissioned during the year including a salt water pumping station at Yau Tong. Pumping plants for another six pumping stations were ordered and work commenced on the design of two more.
