Download or read book Ensuring a Sustainable Future written by Environmental Protection Atgency (Us) and published by Government Printing Office. 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.

This book was released on 2014 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of our drinking water and wastewater infrastructure are at the end of their useful life facing significant deterioration, causing leaks and water losses. These losses are a waste of both energy and water, considering both water and wastewater treatment systems are very energy intensive. In order to deal with the urban water infrastructure issues, EPA has listed out the following goals: asset management, water and energy efficiency, infrastructure financing, price of water services and alternative technologies assessment. This dissertation addresses two of EPA's goals, water and energy efficiency and alternative technologies assessment. Three approaches were taken to address these goals. In the first approach, the life cycle energy demand for water and wastewater studies were reviewed from literature to understand the energy requirements of these systems and propose a benchmark energy demand. System boundaries, data collection and reporting, type of LCA used, were identified as the factors that influence the total energy use and energy use reporting. Energy use data of water and wastewater treatment systems have been compiled to obtain ranges of 2.8 x 10-06 - 4.8 x 10-03 kWh per L and 2.8 x 10-09 to 1.32 x 10-02 kWh per L respectively. From the details obtained from literature, energy use ranges for specific processes related to water and wastewater could not be obtained due to lack of appropriate data reporting. Development of an appropriate data reporting procedure for water and wastewater treatment life cycle assessments is required to be able to collect, use and analyze this data. In the second approach, alternative technologies were assessed to reduce the energy requirements of the water and wastewater treatment systems. The quality of drinking water cannot be compromised; however, the use of potable water flushing toilets can be avoided to conserve energy and resources. In approach 2A Standard sanitation technology (Scenario 1) was compared with the following alternative technologies high efficiency toilets flushed with potable water (Scenario 2), standard toilets flushed with rainwater (Scenario 3), high efficiency toilets flushed with rainwater (Scenario 4), and composting toilets (Scenario 5). These technologies were compared on two University Buildings, based on cost, energy and carbon emissions using Economic Input Output Life Cycle Assessment (EIO-LCA). Based on all the three indicators, scenarios 4 and 5 were the most preferable scenarios. Life cycle assessments (LCAs) are done largely either using the economic input-output approach or process based approach. While both methods are commonly used, it is not well known how much the LCA results might change when one method is used instead of the other. In approach 2B the technologies from 2A were compared with the conventional sanitation technology using EIO-LCA and process based LCA. The results were overall higher from EIO-LCA except for potable water treatment. EIO-LCA was found better for modeling. The difference in magnitude for all products and processes involved is reported. More detailed documentation from both models is required for an explanation of the difference in magnitudes. There was no difference in the suggested ranking of scenarios from both the models. In approach three, composting toilets were studied in more depth. The composting toilets technology demonstrated potential for the most sustainable sanitation technology among all the five technologies compared. In approach 3A, the composting results however, were preliminary. A review of the available composting toilet technologies and the composting process was conducted to better understand the technology. The review, categorized the different types of composting toilets. Factors reported as affecting the composting process and their optimum values were identified as; aeration, moisture content (50-60 %), temperature (40-65oC), carbon to nitrogen ratio (25-35), pH (5.5-8.0) and porosity (35-50%). Barriers in implementing this technology were also identified. In approach 3B, Composting is an old technology and more popular only in rural areas that are disconnected from the urban water and wastewater infrastructure. The impact of using these technologies in urban areas on a large scale has not been evaluated before. In approach 3B, use of composting toilets with land application and back yard application of compost were modeled in GaBi for a tenth of the city and compared to the conventional sanitation system for the city of Toledo. Results show that composting toilets are beneficial if a tenth of the city shifts from conventional to composting technology.
Book Synopsis Urban Water Security by : Robert C. Brears
Download or read book Urban Water Security written by Robert C. Brears and published by John Wiley & Sons. This book was released on 2017-01-17 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 21st Century, the world will see an unprecedented migration of people moving from rural to urban areas. With global demand for water projected to outstrip supply in the coming decades, cities will likely face water insecurity as a result of climate change and the various impacts of urbanisation. Traditionally, urban water managers have relied on large-scale, supply-side infrastructural projects to meet increased demands for water; however, these projects are environmentally, economically and politically costly. Urban Water Security argues that cities need to transition from supply-side to demand-side management to achieve urban water security. This book provides readers with a series of in-depth case studies of leading developed cities, of differing climates, incomes and lifestyles from around the world, that have used demand management tools to modify the attitudes and behaviour of water users in an attempt to achieve urban water security. Urban Water Security will be of particular interest to town and regional planners, water conservation managers and policymakers, international companies and organisations with large water footprints, environmental and water NGOs, researchers, graduate and undergraduate students.

Book Synopsis Assessment Framework for Urban Water Security by : Hassan Tolba Aboelnga
Download or read book Assessment Framework for Urban Water Security written by Hassan Tolba Aboelnga and published by BoD – Books on Demand. This book was released on 2021-01-01 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban water security is crucial for achieving sustainable development, peace, and human health and well-being. Framing urban water security is challenging due to the complexity and uncertainty of its definition and assessment framework. Several studies have assessed water security in widely divergent ways by granting priority indicators equal weight without considering or adapting to local conditions. This dissertation develops a new urban water security definition and assessment framework applicable to water scarce cities, with a focus on Madaba, Jordan. It takes a novel and systematic approach to assessing urban water security and culminates in integrated urban water security index (IUWSI) as a diagnostic tool and guide management actions. The dissertation suggests a new working definition of urban water security based on the United Nations (UN) Sustainable Development Goal 6.1 on safe drinking water for all and the human rights on water and sanitation as follows: The dynamic capacity of water systems and stakeholders to safeguard sustainable and equitable access to water of adequate quantity and acceptable quality that is continuously, physically and legally available at an affordable cost for sustaining livelihoods, human well-being and socioeconomic development, ensuring protection against waterborne pollution and water-related disasters, and for preserving ecosystems in a climate of peace and political stability. This proposed definition captures issues at the urban level of technical, environmental and socioeconomic indicators that emphasize credibility, legitimacy and salience. The assessment framework establishes a criteria hierarchy, consisting of four main dimensions to achieve urban water security: drinking water and human well-being, ecosystem, climate change and water-related hazards and socioeconomic aspects (together, DECS). The framework enables the analysis of relationships and trade-offs between urbanization, water security and DECS indicators. The dissertation also provides a structured analysis to understand how urban water is managed in intermittent water supply system, by conducting a water balance analysis after quantifying the components of water losses in Madaba’s water distribution network. The findings showed that Madaba's non-revenue water (NRW) amounted to annual loss of about 3.5 million m3, corresponding to financial losses of 2.8 million USD to the utility, of which 1.7 million USD is the cost of real losses. The dissertation provided an intervention strategy for strengthening infrastructure resilience and reducing leakage via the infrastructure, repair, economic, awareness and pressure (IREAP) framework. The IREAP framework provides a robust strategy to shift intermittent water supply (IWS) into continuous water supply. The IUWSI highlighted the state of water security in Madaba, Jordan and identified the means of implementation to move towards achieving urban water security based on the priorities for Madaba. The drinking water and human wellbeing dimension was the most important priority, receiving a weight of 66.22%, followed by ecosystem (17.15%), socioeconomic aspects (10.18%), and climate change and water-related hazards (6.45%) dimensions. The IUWSI indicated that the urban water security in Madaba is reasonable with a score of 2.5/5 and can meet the minimum requirements in several dimensions, but nonetheless, it has many loopholes to cover. Gaps are clear in the climate change and water-related hazards, and socioeconomic dimensions with scores of 1.6/5 and 2.237/5 respectively. Additionally, specific shortcomings are found in indicators such as water availability, reliability, diversity, and public health. The IUWSI framework assists with a rational and evidence-based decision-making process, which is important for enhancing water resource management in water-scarce cities

Book Synopsis An Integrated Approach to Modelling Urban Water Systems by : David Jonathan Mark Flower
Download or read book An Integrated Approach to Modelling Urban Water Systems written by David Jonathan Mark Flower and published by . This book was released on 2009 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: The energy consumption and greenhouse gas (GHG) emissions associated with urban water systems have come under scrutiny in recent times, as a result of increasing interest in climate change, to which urban water systems are particularly vulnerable. The approach most commonly taken previously to modelling these results has been to consider various urban water system components in great detail, but in isolation from the rest of the system. This piece wise approach is suboptimal, since it systematically fails to reveal the relative importance of the energy consumption and GHG emissions associated with each system component in the context of the entire urban water system. Hence, it was determined that a new approach to modelling the energy consumption and GHG emissions associated with urban water systems was necessary. It was further determined that the value derived from such a model would be greatly enhanced if it could also model the water consumption and wastewater generation associated with each system component, such that integrated policies could be developed, aimed at minimising water consumption, waste water generation, energy consumption and GHG emissions concurrently. Hence, the following research question was posed: How should the relationships between the water consumption, wastewater generation, energy consumption and GHG emissions associated with the operation of urban water systems be modelled such that the impact of various changes to the system configuration made at different spatial scales can be determined within the context of the entire system? In this research project, life cycle assessment ideas were employed to develop such a new modelling methodology. Initially, the approach was developed at the building-scale, such that the end uses of water present in a selected building and any associated appliances could be modelled, along with the fraction of the city wide water supply and waste water systems directly associated with providing services to that building. This vast breadth of scope was delivered by considering only the operational life cycle stage of each urban water system component, excluding both the pre- and post-operational life cycle stages of the associated infrastructure.The value of this pilot model was illustrated by several case studies, focused on residential buildings connected to the centralised water supply and waste water systems in Melbourne, Australia. Later, the approach was extended to the city-scale by using probabilistic distributions of each input parameter, such that all of the end uses of water present in a city, and all of the associated building-scale appliances could be modelled, along with the associated complete water supply and waste water systems. The value of this city-scale model was illustrated by applying it to model a hypothetical case study city, resembling Melbourne, Australia in many ways. Due to a lack of data, this application was limited to the residential sector of the casestudy city, along with the fraction of the citywide water supply and waste water systems directlyassociated with providing services to that sector. The results generated by the pilot and city-scale models showed that the new modelling methodology could be employed at a wide range of scales to assess the relative importance of each modelled urban water system component in terms of the specified results. Importantly, the high resolution of those results enabled the identification of the underlying causes of the relative importance of each urban water system component, such that efficient and effective approaches to reducing each result for each system component could be developed.Interestingly, for the specific case studies investigated, it was revealed that some commonlyneglected system components were actually extremely important, such as domestic hot waterservices, a trend found to be largely driven by hot water consumption in showers.
