The Study On Management Of Urban Water Demand

With urban population increasing and economy developing, conflict betweensupply and demand of urban water becomes more and more intensive. How toimplement effective management towards urban water so as to arrive at urban waterbeneficial recycle and sustainable utility becomes a significant problem considered byall over the world. This paper classified urban water into urban domestic water andurban industry water at first, then analyzed the structure of water demand respectively,including quality demand analysis and quantity demand analysis. Through an analysisof water quality and water quantity demand, the paper has put forward the rationaldemand of water quality and quantity for the industrial production and all kinds ofurban life.This paper used the supply-demand relationship principle of economics toanalyze the influence factors according to urban domestic water and urban industrialwater respectively. The sensitiveness of different factors which influenced rationaldemand of water quality and quantity was analyzed by establishing demand functionand demand elasticity analysis, and the main factor of influencing the urban waterdemand,that is, urban water supply system and rational water pricing system was putforward from the point of management.This paper has put forward the management tactics of water quality demand bymeans of the recycle treatment of the municipal sewage and Supplying wateraccording to different quality. After studying on the meaning, feasibility, user, existingproblem and countermeasure of sewage recycle treatment in our country, the paperdiscussed intension, meaning, feasibility ,different mode of supply water according toquality, and brought forward the new thought of supplying water by different qualityin the city of our country combining the reality of our country.This paper has brought forward the management tactics of water quantitydemand, that is, water quotas management and water price control. On the one hand,the paper studied on the meaning of water quotas, the principle of water quotas, quotaformulation method of domestic water and industrial production water respectively.On the other hand, After discussing the forming mechanism of the rational water price,the paper brought forward the new thought of rational water pricing system, pricestructure, the relationship for different water quality price exchange rate, andcomposition of the water price of two systems and season water price etc, andresearched into the ladder water quantity and ladder water price of the residentdomestic water.
