Under the Landslip Preventive Measures (LPM) Programme, about $1.2 billion was spent in 2010 to improve the safety of slopes. Upgrading works were completed on 375 sub-standard government man-made slopes, all of which were landscaped to blend in with their surroundings. Safety screening studies were completed on 155 private man-made slopes.
A long-term Landslip Prevention and Mitigation Programme (LPMitP) has been launched. It will deal with the landslide risk remaining after completion of the LPM in 2010, by upgrading man-made slopes and systematic mitigation of risk from natural hillside catchments with a known history of landslides where they are close to existing buildings and important transport corridors.
To foster better public understanding of landslide hazards from man-made slopes and natural terrain, a LPMitP launching exhibition and a 'Safer Slopes Safer Living' Fiesta to enhance community resilience to landslide hazards were organised in April 2010 and November 2010 respectively.
Water Supplies
Water from Guangdong
Hong Kong has been receiving raw water from Dongjiang since 1965. Dongjiang is now the major and long term source of raw water for Hong Kong. To accommodate seasonal fluctuations in the local yield, the current agreement for Dongjiang water supply signed in December 2008 provides flexibility in the daily supply rate. This arrangement enables Hong Kong to have better control of the storage level in reservoirs, thereby minimising overflow and saving pumping costs.
Water Storage and Consumption
Full supply was maintained throughout the year. At the end of 2010, some 380 million cubic metres of water was in storage, compared with 410 million cubic metres a year earlier. Hong Kong's two largest reservoirs, High Island and Plover Cove were holding a total of 330 million cubic metres. Rainfall of 2 372 millimetres, 0.5 per cent lower than the annual average of 2 383 millimetres, was recorded in 2010.
The average daily supply of fresh water in 2010 was 2.564 million cubic metres, compared with 2.608 million cubic metres in 2009. Some 936 million cubic metres. of fresh water was consumed in 2010, compared with 952 million cubic metres in 2009. In addition, 270 million cubic metres of salt water was supplied for flushing, compared with 271 million cubic metres in 2009.
Total Water Management
The Government is implementing the Total Water Management strategy that aims to manage the water demand and supply in an integrated, multi-sectoral and sustainable manner. The key initiatives on water demand management include implementation of active leakage control, pressure management, extension of the use of sea water for toilet flushing, stepping up public education on water conservation and promotion of the use of water saving devices. During the year, the
