of revitalising water bodies to promote greening, biodiversity, beautification and water friendliness to turn the drainage facility into a green river corridor, in addition to enhancing flood prevention.
The department carries out regular inspection, de-silting and repair works for drainage systems. In 2014, about 2,483 kilometres of drains and watercourses were inspected and about $118 million was spent on maintenance work.
Slope Safety
The Civil Engineering and Development Department's comprehensive slope protection effort has brought about a substantial improvement in slope safety by improving standards and technology, ensuring that all the new man-made slopes meet the current safety standards, improving the safety of existing man-made slopes, and also mitigating natural terrain landslide risks. The department also issues public warnings and provides information, education and community advisory services on slope safety.
Under the long-term Landslip Prevention and Mitigation Programme, about $1 billion was spent in 2014 to upgrade 154 sub-standard government man-made slopes and mitigate the landslide risk of 33 natural hillside catchments, all landscaped to blend in with their surroundings. In addition, safety screening studies on 110 private man-made slopes were conducted.
Water Supplies
Water from Guangdong
Hong Kong has received raw water from Dongjiang since 1965 and this is now the city's major source of raw water. The current agreement for Dongjiang water supply maintains flexibility in the daily supply rate, securing a reliable source of supply and avoiding wastage of precious water resources. About 724 million cubic meters of water was imported from Dongjiang in 2014.
Water Storage and Consumption
Full supply was maintained throughout the year. At the end of 2014, some 378 million cubic metres of water was in storage reservoirs. Rainfall of around 2,638 millimetres was recorded in 2014.
The average daily supply of fresh water in 2014 was around 2.63 million cubic metres. Some 959 million cubic metres of fresh water was consumed in 2014 and around 271 million cubic metres of sea water was supplied for toilet flushing.
Total Water Management
The government's Total Water Management strategy aims to manage water demand and supply in an integrated, multi-sectoral and sustainable manner. In 2014, the government continued to promote water conservation in both the domestic and non-domestic sectors, including launching the 'Let's Save 10L Water' campaign, installing flow controllers in selected
