Quality testing is an important measure for quality controlment in water conservancy projects.In this paper，several testing patterns in other provinces are introduced.The paradigm of parallel testing by a third party used in the construction of large water conservancy projects in Jiangxi province is mainly explained.It’s also discussed the currently undergoing trail of “integration of all three testing” mode in Jiujiang city，which delegates self-inspection，parallel testing and completion sampling of small water conservancy projects to one third party.The paper analyzes the advantages and disadvantages of aforementioned two testing models in hoping to provide technical support for water conservancy project constructions.
