Indeed, background leakage is so pervasive that water suppliers accept 3,500 litres of water per kilometre of pipe per day as the minimum achievable loss.
事实上，底面渗漏现象随处可见，供水商也接受了每日每千米管道3500升的最低漏水量。

The linear loss of sewage flowing in pipe is approximately equal to that of water pipe flow. So it's feasible to accept the method in use at present.
污水在管道内流动的沿程损失与清水流动时近乎相等，所以目前在管道水力计算中所采用的处理方法是可行的。
