title: [National survey of urban sewage reuse in China].
abstract: On the basis of the national survey of the urban sewage treatment, the survey of 2007 national urban sewage reuse was conducted under the charge of the Ministry of Water Resources. The survey results indicated that the amount of urban sewage reuse was 17.9 x 10(8) m3 x 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 x 10(4) m3 x d(-1), which produced 5.74 x 10(8) m3 reclaimed water in 2007. The total investment of sewage reclaiming plants was 56.44 x 10(8) Yuan, in which 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.
