自來水工程簡史1804 Paisley, Scotland 將過濾之水送至用戶家中1807 Glasgow, Scotland 將水以管線送至用戶1810 England, Water Closet (W.C.)1832 London, Typhoid 流行1847 London, Typhoid 流行1848 London, Cholera 流行1849 Cholera 14,600 deaths1854 Cholera 10,675 deaths Dr. John Snow

歷史迴顧• 1839 年，在倫敦約有一半之喪禮係為小於10 歲之孩童所舉行，許多死於傳染性疾病。

• 1847 年，約有 50 萬倫敦人 (全部人口之 ¼)得到傷寒，主要因衛生條件差。

• 19 世紀中葉，倫敦人之平均壽命 27 歲，勞工階級只有 22 歲。

Highlights• Like oil in the 20th century, water could

well be the essential commodity on which the 21st century will turn

• Over a billion people lack access to clean drinking water

• Over 2 billion people live without adequate sanitation

• Each year 5 million people die, mostly children, from preventable waterborne disease

Water Resources

• Mean annual rainfall about 2500 mm• Distinct dry and wet seasons.

Drought in dry season, and flooding in typhoon season are quite common.

• Rivers are short and steep Reservoirs are usually required

• Source water for public water supply 64.3% reservoirs, 21.7% direct surface water, 14% groundwater.

• Owing to environment consideration, building new dam is quite difficult nowadays.

High Turbidity Source Waters• During the summer months of 2004 and 2005, the turbi

dity of the source water from Shihmen Reservoirs have been over 100,000 NTU

• The public water supply of the Taoyuan area was suspended for 19 days, affecting the daily life of millions people.

• Estimated economic loss about NT$5 billions.

High Turbidity Source Waters• Kaoping River Weir

Turbidity has been reached 25,000 NTU in July,

2005.

In the past, several thousands NTU were quite common during typhoon seasons.

No major reservoirs in Kaohsiung area.

Drought and Flooding

• On August 6, 2009, drought warning was issued.

• On August 8, Typhoon Morakot came with total precipitation of 2965 mm.

• The source water turbidity of Nanhua Reservoir over 70000 NTU.

• Water supply to parts of Tainan and Kaohsiung area was suspended for about a week.
