South to North Water Transfer Project in China is the largest project over centuries to solve the water shortage problem in vast areas of northern China. It comprises of three routes: the eastern, central and western route and this study mainly focused on the eastern route. As water quality is the key factor for the eastern route, this paper examined the main factors influencing water quality of the main route south of the Yellow River, by investigating the point source, non-point source (diffusive source) and internal source pollutions along the main eastern route and in its drainage basins, and assessing the current water quality in the waterways. According to the complicated and combined systems of rivers and lakes in this route, one-dimensional water quantity and quality model for rivers and two-dimensional model for lakes were developed to simulate the hydrodynamic and pollutant transport processes. The numerical method and model algorithm were described. The values of model parameters were estimated by using field-monitoring data along the main route and the inverse modeling technique. Established models were employed to predict the degradations of CODMn and NH4+-N in the main stream, under the conditions of current pollution loads and different hydrologic conditions. Schemes were present for controlling total quantities of pollutants from point source and non-point source along the main route to secure water quality for the eastern route.
South to North Water Transfer Project in China is designed to solve water shortage problem and support sustainable social and economic development in northern China. Eastern Route Project (ERP) is one of the three components of the water transfer project. Pumping water from the Yangtze River in Yangzhou, Jiangsu Province, ERP utilizes the Grand Canal and its parallel rivers to transfer water from south to north. It also employs Hongze Lake, Huoma Lake, Nansi Lake and Dongping Lake for flood regulation. There are two water transfer ways after Dongping Lake.

According to the investigation and analysis on pollution sources along the main route for water transfer and its adjacent area, the main sources that influence the water quality of waterways were identified in this paper. The urban point pollution sources are the principal sources, the non-point pollution sources take the second place, and the internal pollution sources are less significant. So wasterwater treatment plants in cities and towns along the main route should be built as soon as possible to ensure the water quality in ERP.
