随着城市人口的剧增,人民生活水平的提高和城市工业的迅速增长,原有城市附近的水源大都已不能满足用水增长的要求。据有关资料介绍:全国每天有1000万立方米以上的水是从10km以外的水源地取来的。输水总长度已达1600km以上,全国城市总供水量约5000万立方米/日,长距离输水已占城市总供水量的20%左右,这是一个很大的比例。下面就长距离输水的有关问题谈几点看法:
With the dramatic increase of the urban population, the improvement of people’s living standards and the rapid growth of urban industries, most of the water resources in the original cities can no longer meet the requirements of water use growth. According to relevant information: There are more than 10 million cubic meters of water in the country every day from 10km away from the water source.

Here’s a few comments on the issue of long-distance water delivery:
