On the basis of the water rate adjustment in every city of Hebei province within the year 2002, the author analyzed the common trend in the current water price adjustment. Meanwhile the influence of water price adjustment on household bearing capacity, water - saving equipment market and urban water utilization rate is also be analyzed. Based on above analysis, indicated the adjustment trend of the water price in Hebei province.
That the connotations, forming mechanisms, and the calculation methods on each element involved in water price are studied systematically and deeply. The water prices of Luanhe basin, Tianjin city and YinLuanRuJin IWT system in the typical year 2000 are calculated as the cases.
Based on the analyse of present situation and problems,the authors offered some countermeasures agains the shortage of water resources and suggestions on developing sustainability,such as enhancing cycle utilization and constituting reasonable water prices.
For promoting water use efficiency, China has been reforming her water management system, including water right system and water price system.
Indicators are linked to criteria reflecting stakeholders concerns in the 2005 field survey, such as fulfilling water demand, water price, technical and economical efficiency, social and environmental impacts.
The influence of irrigation efficiency is higher as water price increases.
This compares well with that of other processes for desalination and is less than the fresh water price for new mines in South Africa, viz.
According to this model calculation, the average water price should be twice as high as it is.
This article develops a method for establishing water prices and their effects in order to provide policy makers an environmentally and socially optimal range of regional prices for irrigation water.
Potential water prices are established, ranging from prices that minimize the negative impact in the regional economy to those that totally internalize the environmental cost of water.
During this time water prices increased by 45-180% and government O>amp;amp;M subsidies were eliminated.
Results reveal that even with significantly higher water prices, water users have invested more in their systems than during the post-IMT period and consider their overall irrigation costs to be lower.
Lowering the wastewater treatment level decreases fertilization costs because of the increased levels of available nutrients left in the water, and irrigation costs decrease if water prices reflect the lower treatment costs.
