The construction of Sponge City (SPC) in China has caused a huge social transformation, and the application of its core low-impact development facilities (LIDs) has changed the lives of residents from the details. Controlling runoff water quantity and its water quality are the two main objectives of low impact development measures. This paper discusses the results of water quality testing, comparing content changes of total phosphorus (TP), total nitrogen (TN), and chemical oxygen demand (COD) and total suspended solids (TSS) measured from water samples collected from the same LID facilities established by LCTIP three times a month during 2018 the local rainy season. The values changes of various pollutants from sampling points to the outlet show that the water quality of after LID facilities is close to the state of natural rain before development. The water purification effect of the LID facility was verified. At the same time, it is necessary to understand that more factors will have an impact on water quality. Therefore, the limitations of current knowledge and recommendations for future research are also discussed.
