completed during the year and the commissioning of the Plover Cove Water Scheme. The volume of high voltage plant under maintenance increased considerably and it is of interest to note that this Office is now the largest industrial user of high voltage equipment in the Colony, with the exception only of the two power companies. A contract for maintenance of control and instrumentation equipment associated with the Plover Cove Scheme was entered into, provision being made for in-service training of personnel to take over associated responsibilities.

Plover Cove Scheme
7.48. Stage I works which include pumping water from Tai Po Tau, through eight miles of tunnel to a treatment works at Sha Tin and thence via Lion Rock tunnel into service reservoirs in Kowloon was completed. The scheme enables water from China and flood water from the River Indus and the Tai Po river to be treated at Sha Tin Treatment Works. A reservoir at Lower Shing Mun collects the yield of the catchment area between Tai Po and Lower Shing Mun by means of stream intakes and deep shafts which divert the stream flows into the eight mile long tunnel.
7.49. The Sha Tin Treatment Works was completed to its design capacity of 80 million gallons per day and work on remote control of the system from Sha Tin was well advanced.
7.50. Stage II works proceeded satisfactorily. The main dam at Plover Cove was closed on 6th February, 1967 and pumping out of the impounded sea water begun. The lining of the main tunnel linking Plover Cove with Tai Po Tau was virtually complete. This tunnel will carry pumped water from Plover Cove Reservoir to Tai Po Tau for repumping to Sha Tin Treatment Works and will also be able to deliver surplus water from the Tai Po River, the River Indus and China by gravity
