Water from Guangdong
Hong Kong began receiving raw water from the Shenzhen Reservoir in
Guangdong in 1960 under a scheme that provides it with 22.7 million cubic metres
of water a year. The infrastructure for channelling water to Hong Kong was expanded
in 1965 with the building of an 80-kilometre transfer system known as the Dongshen
Water Supply System to deliver water from Dongjiang, or East River, to Hong Kong
via Shenzhen Reservoir.
Dongjiang is the major source of raw water for Hong Kong. The new agreement
signed in April 2006 guarantees long-term supply of Dongjiang water to Hong Kong.
Water Storage and Consumption
Full supply was maintained throughout the year. At the end of 2006, some
435 million cubic metres of water was in storage, compared with 461 million cubic
metres a year earlier. Hong Kong's two largest reservoirs, High Island and Plover Cove
held a total of 387 million cubic metres. Rainfall of 2 628 millimetres, 19 per cent
higher than the annual average of 2 214 millimetres, was recorded in 2006.
The average daily consumption of water in 2006 was 2.64 million cubic metres,
compared with 2.65 million cubic metres in 2005. Some 963 million cubic metres of
potable water was consumed in 2006, compared with 968 million cubic metres in
2005. In addition, 260 million cubic metres of sea water was used for flushing,
compared with 263 million cubic metres in 2005.
Total Water Management
The Government is proceeding with the Total Water Management Programme
for rational utilisation, protection and management of water resources and for
exploring new water resources. The Government has completed the testing of the
pilot desalination plant in Tuen Mun and is now carrying out further tests on the pilot
plant in Ap Lei Chau to determine different coastal seawater conditions. On the
question of water reclamation and reuse, the Government has commissioned two
pilot schemes for using reclaimed water in Ngong Ping and Shek Wu Hui. In addition,
the Government is conducting a study on long-term strategies to be adopted under
the Total Water Management Programme in Hong Kong. The study will take into
account the findings of the various Hong Kong pilot schemes and those of similar
schemes overseas. The study will be completed by the end of 2007.
Water Works
Work on the first and second stages of the programme for the replacement and
rehabilitation of some 3 050 kilometres of water mains began in December 2000 and
January 2007 respectively. Work on the third stage will be carried out between late
2008 and 2013. Planning of the final stage is under way, and work on it will be
carried out from early 2011 to 2015.
The construction of Magazine Gap Road No. 3 Fresh Water Service Reservoir and
Quarry Bay Salt Water Service Reservoir, and remedial works to the High Island
Reservoir's West Col Dam were completed during the year. The contract for remedial
work on the rip-rap at the Plover Cove Reservoir's main dam has been approved and
work on the project has begun. Building of a new reservoir to serve Sheung Shui and
Fanling is progressing.
The department continues to work on plans for providing a reliable supply of
fresh and salt water to new and redeveloped buildings springing up across Hong
Kong. The districts where these developments are taking place include Central, Wan
Chai, and western and southern areas on Hong Kong Island; Sham Shui Po and Kwun
Tong in Kowloon; and Sha Tin, Tuen Mun, Yuen Long, Tseung Kwan O, Lantau and
Cheung Chau in the New Territories.
The plans provide for the building of additional service reservoirs, pumping
stations and water supply networks in Wan Chai, Kowloon East, West Kowloon
Reclamation, Cha Kwo Ling, Tuen Mun, Sha Tin, Yuen Long, Tai Po, Tin Shui Wai,
Tseung Kwan O and North Lantau.
Water Accounts and Customer Relations
The number of consumers with water accounts continues to rise by about
0.2 per cent per year. At year-end, the department was handling approximately
2.67 million accounts. To provide greater convenience to customers, the paying of
water bills and other matters such as change of addresses can now be done online.
The Water Supplies Department also continues to act as an agent for collecting
sewage charges and trade effluent surcharges on behalf of the Drainage Services
Department. The Customer Care and Billing System went into operation in June.
The voluntary Fresh Water Plumbing Quality Maintenance Recognition Scheme,
launched in July 2002 to encourage proper maintenance of internal plumbing
systems in buildings, continues to receive public support. People taking part in the
scheme may now renew their participation certificates every two years instead every
year.
