Forecasting of demand for water in advance is critical for water supply planning. The paper made water consumption analysis by industry in China. With multiple regression analysis, time series analysis and expert experience methods, the water demand by industry in China in 2021 was forecasted. The results show that the total demand of water in China in 2020 will be about 598.06 billion cubic meters, slightly less than that in 2020. Among them, the agricultural water demand would account for about 61.1%, the industrial water demand account for about 19.6%. For the domestic and the environmental water demand, the proportion would be 15.1% and 4.2% respectively.
