But the average water charges of NT $ 7 to NT $ 9 per unit levied in the Taiwan Area are among the cheapest of any developing or developed nation. One of the reasons is that at present the water companies use water from reservoirs, but the cost of constructing the reservoirs is borne separately by the government.
但台灣地區水費每度平均七到九元，幾乎是開發中、已開發國家最便宜的，原因之一是自來水公司用水庫水，水庫建設費用卻是政府預算另外支出。
