The survey results indicated that the amount of urban sewage reuse was 17.9×108 m3·a-1, mainly used for industry, 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, of which the production capacity of reclaimed water reached 347.75 × 104 m3·d-1, which produced 5.74×108 m3 reclaimed water in 2007. The total investment of sewage reclaiming plants was 56.44 × 108 Yuan, in which the central government investment, local fiscal investment and other investments accounted for 16%, 26% and 58%, respectively.
