水是世界上最寶貴的一種資源，也是維持生命的理想液體。哺乳動物體內60%至65%是水，人類體重的2/3、大腦的99%、骨骼的44%也都是水。缺了水，人類和地球將不能存活，森林將不復存在，植物將滅亡，地球上將出現無邊的沙漠，生命的跡象將消失。
目前全世界的淡水資源僅占其總水量的2.5%，其中70%以上被凍結在南極和北極的冰蓋中，加上難以利用的高山冰川和永凍積雪，有87%的淡水資源難以利用。人類真正能夠利用的淡水資源是江河湖泊和地下水中的一部分，約占地球總水量的0.26%。
鑒于全球淡水資源不僅短缺、許多國家將很快陷入缺水的困境，經濟發展將受到限制，1993年1月18日，第47屆聯合國大會作出決議，確定每年的3月22日為“世界水日”。1988年《中華人民共和國水法》頒布后，水利部即確定每年的7月1日至7日為“中國水周”，考慮到“世界水日”與“中國水周”的主旨和內容基本相同，故從1994年開始，把“中國水周”的時間改為每年的3月22日至28日，時間重合，使宣傳活動更加突出“世界水日”的主題。
