Methods From2011 to 2013, the samples of secondary water supplying were analyzed in Yueyang City based on the method of regular sampling.Results 2070 water samples were collected and evaluated in Yueyang from 2011 to 2013. 667 water samples were from pump-tank（pool） joint water supply and the qualified ratio is 58.0%. 1403 samples were pressurized water with qualified ratio of 84.1%.Conclusion Secondary water supplying development presents a significant imbalance in Yueyang City.
