Abstract This paper describes the use of integrated resource planning for water and wastewater service provision by a major urban water utility. This methodology aims to meet the water and sewerage needs of the community at the least cost and includes an explicit analysis of the costs and benefits of measures that reduce the demand for water and the discharge of wastewater effluent. It therefore requires disaggregation of the demand for water into end-uses and a consideration of the linkages between the water supply and sewerage components of the business. This approach has significant advantages in economic, environmental, and social terms. The case study results indicate that significant investments in water efficiency programs are justified on economic grounds, particularly where augmentation of water and sewerage infrastructure is planned. Three studies undertaken as part of Sydney Water's efforts to integrate supply- and demand-side planning are described in this paper: first, a major integrated resource planning exercise designed to reduce demand for water by up to 35 percent, costing more than AU$25 million; second, a case study in a series of small towns where the benefits arise from reducing the capacity of sewage treatment plants by reducing wastewater flow; and third, in a major industrial region where water efficiency measures integrated with reuse measures reduce overall costs. 相似文献

Multicriterion Analysis for Sustainable Water Resources Planning: A Case Study in Spain 总被引:7,自引:1,他引:7
The present article demonstrates the implementation of Multicriterion Decision Making (MCDM) analysis for a case study of Flumen Monegros irrigation area in the Huesca province of Spain. The criteria used to rank alternativesconsist of (1) economic factors including initial cost ofirrigation system, maintenance cost, profitability of crops,extent of European subsidies; (2) environmental factors whichcomprise water volume, water quality after irrigation, efficiency of the use of water, resistance to floods or droughts; (3) Social factors including employment of rurallabour, area non-cultivated. Alternative policies areformulated by mixing factors such as irrigation system, waterpricing, water allocation, crop distribution, fertiliser use,subsidies received. Multicriterion Sorting Technique (MCST)ELECTRE-TRI is employed to reduce the large size payoff matrixto predefined categories for further usage of MCDM techniques.Five MCDM techniques, namely, PROMETHEE-2, EXPROM-2, ELECTRE-3, ELECTRE-4, and Compromise Programming (CP) are employed torank the alternatives. Spearman rank correlation coefficientis employed to assess the correlation coefficient between theranking patterns obtained by the above MCDM techniques.Additive ranking principle is used for group decision makinganalysis. Results indicate that five MCDM techniques choosethe same alternative strategy as the preferred one. 相似文献

A Compromise Solution in Water Resources Planning 总被引:2,自引:2,他引:2
Serafim Opricovic 《Water Resources Management》2009,23(8):1549-1561
The paper emphasizes compromise based on cooperativeness as a solution of a decision problem in water resources planning.
A decision making process committed to consensus utilizing compromise solution as a consensus proposal is presented. The presented
methodology is utilized to study the development of a reservoir system for the storage of surface flows of the Mlava River
and its tributaries for regional water supply. The method VIKOR is applied to determine compromise solution of a problem with
noncommensurable and conflicting criteria including economic, environmental, social, and cultural features. The obtained compromise
provides a maximum group utility of the “majority” and a minimum individual regret of the “opponent”. 相似文献

Strategic Water Resources Planning: A Case Study of Bangladesh 总被引:1,自引:0,他引:1
Many agrarian countries have heavily invested in large-scale water projects to promote their agricultural development. There have been, however, few attempts to devise strategic water resources planning accounting for the macroeconomic linkages ofagriculture. This article presents such a strategic water resourcesplanning framework for Bangladesh. First, a dynamic costminimization model is solved to compute the optimal investmentneeded in various water projects such that an agricultural growthtarget can be met. Next, the minimum cost solution is againderived accounting for the macroeconomic linkages of agriculture,which, under different macroeconomic scenarios, results innoticeably different policy implications for optimal waterplanning. These results suggest that the traditional sectoralapproaches of planning water investment projects are generallyinconsistent with the broader macroeconomic reality of Bangladesh. 相似文献

A novel dynamic computable general equilibrium model based on National Water Resource Input Holding Output Table is proposed
to calculate the Shadow Price of water resource in China. Unlike previous approaches, the dynamic Shadow Price of water resource
is largely based on the scarcity extent and can reflect the marginal long-term value in the balanced growth path of China.
Firstly, the basic concepts of dynamic Input Output analysis and Turnpike Theory are reviewed. Then, Dynamic Computable General
Equilibrium (DCGE) is elaborated to calculate the Shadow Price, including the definition and computer-based algorithm. Furthermore,
Shadow Price of water resource in China from 1949 to 2050 is calculated based on the DCGE. Also the sensitivity analysis of
the DCGE for Shadow Price of water resource in China is presented. Dynamic Shadow Price of water resource has two meanings
for China government: (1) Project evaluation. Every large-scale project in China must have national economic evaluation and
the dynamic Shadow Price is prerequisite for national economic evaluation. (2) Market price of water resource. A lesson from
this paper is that Shadow Price of water resource in domestic market of China should be rewritten according to the dynamic
Shadow Price. In addition, the parallel computations approach could also be used to solve these problems in different countries
or for different natural resources.
