Based on the national survey of the urban sewage treatment, we conducted the survey of 2007 national urban sewage reuse under the charge of the Ministry of Water Resources. The urban sewage reuse data were collected. The survey results indicate that the total amount of urban sewage reuse was 17.9 × 10⁸ m³/a, mainly for industrial, landscape, agriculture forestry, animal husbandry, urban non-potable water, and groundwater recharge. The urban sewage reuse rate was 5.23%. There were 127 sewage reclaiming plants in China, the production capacity of reclaimed water reached 347.75* 104 m3/d, and produced 5.74 × 10⁸ m³ reclaimed water in 2007. The total investment of sewage reclaiming plants was 56.44×10⁸ Yuan. The central government investment, local fiscal investment and other investments accounted for 16%, 26% and 58% respectively. The reclaimed water price varied greatly with the purposes or areas.
