城市淨脈 A CITY’S HIDDEN NETWORK
看不見的、看得見的一樣重要 What is unseen is as important as what is seen
雖然污水收集及處理對城市居民的健康至關重要，不過雨水下水道在城市中也發揮著重要作用。
過去幾十年來，在臺灣快速發展暨都市化的過程中，天然綠地空間已經被混凝土取而代之。
導致的結果便是，土地的天然保水能力逐漸喪失，因為混凝土根本不能吸收雨水。
當極端氣候導致強烈暴雨或是颱風帶來大量雨水時，雨水下水道就必須設法應對處理，以防大量雨水淹沒了城市。
然而，雨水下水道僅是防洪平衡措施中的一部分而已。
為了降低淹水災害，政府以「都市總合治水」策略，從雨水下水道、土地規劃及經濟發展等因素都獲得了全方位的考量；新規劃開發項目中，運用工程創新作為、增設滯洪設施以及綠色空間需求的增加等方式，大大提高都市的保水性。
誰知道下水道居然有助於改善城市公共衛生、預防城市洪災，以及促進環境保護呢？
這些城市淨脈緊密連結，保護著重要的水資源，並且維護著居民的生命財產安全。
While wastewater collection and treatment are critical to the health of urban residents, storm sewers also play an important role in the city. Green space has given way to concrete during the island's rapid development and extensive building projects over the past few decades. As a consequence, there has been a loss of the land's natural water retention as concrete cannot absorb rainwater. When an extreme weather event like a severe storm or typhoon unleashes heavy rain, storm sewers must cope with the water, so it does not flood the city. However, storm sewers are only part of the equation for water management and flood prevention.
To reduce flooding, an integrated urban drainage management plan has been
adopted, where all the factors-storm sewers, land planning and economic development are considered together.
Engineering innovations, additional flood detention facilities and increased green
space requirements in new development projects have improved water retention in
cities.
Who knew that sewers help improve urban public health, prevent urban flooding and boost environmental protection? Together they protect vital water resources and maintain the safety of people and property.
