Available in PDF, EPUB and Kindle. Book excerpt: A common characteristic of water demand in urban areas worldwide is its inexorable rise over many years; continued growth is projected over coming decades. The chief influencing factors are population growth and migration, together with changes in lifestyle, demographic structure and the possible effects of climate change (the detailed implications of climate change are not yet clear, and anyway will depend on global location, but must at least increase the uncertainty in security of supply). This is compounded by rapid development, creeping urbanization and, in some places, rising standards of living. Meeting this increasing demand from existing resources is self-evidently an uphill struggle, particularly in water stressed/scarce regions in the developed and developing world alike. There are typically two potential responses: either "supply-side" (meeting demand with new resources) or "demand-side" (managing consumptive demand itself to postpone or avoid the need to develop new resources). There is considerable pressure from the general public, regulatory agencies, and some governments to minimise the impacts of new supply projects (e.g. building new reservoirs or inter-regional transfer schemes), implying the emphasis should be shifted towards managing water demand by best utilising the water that is already available. Water Demand Management has been prepared by the academic, government and industry network WATERSAVE. The concept of the book is to assemble a comprehensive picture of demand management topics ranging from technical to social and legal aspects, through expert critical literature reviews. The depth and breadth of coverage is a unique contribution to the field and the book will be an invaluable information source for practitioners and researchers, including water utility engineers/planners, environmental regulators, equipment and service providers, and postgraduates.

Available in PDF, EPUB and Kindle. Book excerpt: Recent changes in the New South Wales water utilities show a trend towards usage-related pricing, with the aim of providing efficient signals for consumption. This thesis evaluates alternative pricing strategies for water against the criteria of efficiency and equity while maintaining the financial viability of the public utility. First, the water utility cost structure is examined by developing cost functions to estimate short and long-run marginal costs, using a quarterly time-series data from 1970/71 to 1995/96. Second, a residential water demand model is developed using a panel data set (constructed for the analysis), comprising 822 cross-sectional units and 23 quarterly time periods from 1990/91 to 1995/96. The purposes of developing the demand model are to test the sensitivity of water demand to changes in the tariff structure and to use it to simulate the impact of alternative pricing strategies. Third, the simulation model is developed to analyse various pricing reforms using both the cost and demand model results, where the individual welfare and aggregate efficiency gains are determined under each pricing policy. In addition to this, the distributional effects of various tariff structures are examined. The empirical results of the cost structure estimates are comparable with previous studies. The demand estimation indicates that consumers respond to price, therefore price can be considered as a tool in the implementation of demand management strategies. However, the magnitude of the price elasticity suggests that substantial increases in price would be required to influence demand. Finally, the simulation results show that in the case of movement from the actual tariff structure to a two-part tariff policy (where the usage charge is equal to the short-run marginal cost), leads to highest efficiency gains.

Book excerpt: Rather than allowing water prices to reflect scarcity rents during periods of drought-induced excess demand, policy makers have mandated command-and-control approaches, like the curtailment of certain uses, primarily outdoor watering. Using unique panel data on residential end-uses of water, we examine the welfare implications of typical drought policies. Using price variation across and within markets, we identify end-use specific price elasticities. Our results suggest that current policies target water uses that households, themselves, are most willing to forgo. Nevertheless, we find that use restrictions have costly welfare implications, primarily due to household heterogeneity in willingness-to-pay for scarce water.
Download or read book Preparing Urban Water Use Efficiency Plans written by Lisa Maddaus and published by IWA Publishing. This book was released on 2013-11-15 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many communities are facing water scarcity in developing and developed countries alike. There are numerous publications and on-going research studies documenting the changes in our climate and potential for worsening shortages in our future. Meeting future potable water demands as communities continue to grow will rely heavily on using our existing water resources more efficiently. Preparing Urban Water Use Efficiency Plans provides detailed approaches to developing and implementing a water conservation plan. This book covers the broad spectrum of conservation planning for urban communities including achieving more efficiency from: Residential domestic uses Commercial and governmental facilities use Industrial uses Pricing Water Loss Control Programs The steps in the Guide clearly outline and provide sample calculations to aid determining which water use efficiency activities are financially justifiable to undertake. The end result is a plan that policy decision makers can adopt and fund, and that water service provider staff can implement to help increase their community's water reliability. It includes numerous case studies and a Microsoft Excel based software tool to allow planners to evaluate the business case for implementing various water conservation activities. This book is an essential resource for professionals in water and wastewater resources, particularly for planners and engineers. It is also a useful guide for Post Graduate and Undergraduate students. Author(s): Lisa Maddaus, William Maddaus and Michelle Maddaus, Maddaus Water Management Inc.
Download or read book Demand Supply and Welfare Aspects of Pipe borne Water in Sri Lanka written by Dinusha Dharmaratna and published by Cambridge Scholars Publishing. This book was released on 2011-09-22 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water institutions establish the incentives, information, and compulsions that guide behaviour and influence economic outcomes. Water pricing policies that reflect the marginal cost of supply can bring about several positive benefits in the pipe-borne water sector including: 1) greater water use efficiency; 2) an increase in revenues that can be utilised to improve services; and 3) additional funds to enhance and expand the operation and maintenance of pipe-borne water supply systems. In order to design an appropriate pricing policy and bring about these positive changes, managers of pipe-borne water supply systems require an understanding of the determinants of water demand, supply and welfare changes. Further, the use of economic methodologies to estimate the effects of factors that influence pipe-borne water demand, supply and welfare in developing nations can assist water utility operators and policy makers to predict consumption responses to changes in water pricing. In turn, this provides important evidence for these decision makers to determine if price changes will result in higher revenues that can be used to fund critical infrastructure extension and maintenance. This is particularly important for developing nations where revenue constraints on water authorities can limit access to pipe-borne water supplies for large sections of the population. This book identifies under-pricing as the major problem faced by the Sri Lankan pipe-borne water sector. Recently, the water authority in Sri Lanka restructured its pricing strategy for pipe-borne water with the objectives of reducing water consumption and expanding the network. However, the success of the current pricing structure in achieving these objectives is uncertain. Therefore, to overcome the problems, this study examines the use of cost-reflective alternative pricing strategies for pipe-borne water distribution services. The book evaluates current and alternative pricing strategies for water against the criteria of efficiency and equity while maintaining the financial viability of the national water utility. In order to analyse the welfare impacts, understanding the demand for pipe-borne water by different user groups and the cost of pipe-borne water provision must be considered.
Download or read book Designing Nonlinear Price Schedules for Urban Water Utilities to Balance Revenue and Conservation Goals written by Frank A. Wolak and published by . This book was released on 2016 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper formulates and estimates a household-level, billing-cycle water demand model under increasing block prices that accounts for the impact of monthly weather variation, the amount of vegetation on the household's property, and customer-level heterogeneity in demand due to household demographics. The model utilizes US Census data on the distribution of household demographics in the utility's service territory to recover the impact of these factors on water demand. An index of the amount of vegetation on the household's property is obtained from NASA satellite data. The household-level demand models are used to compute the distribution of utility-level water demand and revenues for any possible price schedule. Knowledge of the structure of customer-level demand can be used by the utility to design nonlinear pricing plans that achieve competing revenue or water conservation goals, which is crucial for water utilities to manage increasingly uncertain water availability yet still remain financially viable. Knowledge of how these demands differ across customers based on observable household characteristics can allow the utility to reduce the utility-wide revenue or sales risk it faces for any pricing plan. Knowledge of how the structure of demand varies across customers can be used to design personalized (based on observable household demographic characteristics) increasing block price schedules to further reduce the risk the utility faces on a system-wide basis. For the utilities considered, knowledge of the customer-level demographics that predict demand differences across households reduces the uncertainty in the utility's system-wide revenues from 70 to 96 percent. Further reductions in the uncertainty in the utility's system-wide revenues in the, range of 5 to 15 percent, are possible by re-designing the utility's nonlinear price schedules to minimize the revenue risk it faces given the distribution of household-level demand in its service territory.

This book was released on 2008 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing wastewater and drinking water service to citizens requires energy—and a lot of it. The twin problems of steadily rising energy costs and climate change have therefore made the issue of energy management one of the most salient issues facing wastewater and water utilities today. Energy management is also at the heart of efforts across the entire sector to ensure that utility operations are sustainable in the future. More and more utilities are realizing that a systematic approach for managing the full range of energy challenges they face is the best way to ensure that these issues are addressed on an ongoing basis in order to reduce climate impacts, save money, and remain sustainable. Working closely with a number of utilities and others, the Office of Water at the U.S. Environmental Protection Agency (EPA) is proactively addressing this issue by developing this Energy Management Guidebook for Wastewater and Water Utilities that provides a systematic approach to reducing energy consumption and energy cost. This Guidebook was specifically written to provide water and wastewater utility managers with a step-by-step method, based on a Plan-Do-Check-Act management system approach, to identify, implement, measure, and improve energy efficiency and renewable opportunities at their utilities.
