Abstract (sommario):

This study analyzes the traditional water fetching practices,water usage, and scarcity in the Village Kumar Bandi Muzaffarabad.Overall, 93 respondents of the local community of Kumar Bandi were approached. Data has been collected through an interview guide by convenient and purposive sampling. A descriptive model of data collection has been used for acquiring the information. The study draws essential attention to the most critical factor: the abnormal impacts of water fetching on different aspects of water fetching an individual's life, the most important of which is health. The issue of water scarcity has caused damage to religious and traditional local practices besides the danger of whether the water utilized is recommended for use or not. Along with women's health and the educational development of children, Water fetching has adverse effects on people's social, religious, economic, kinship, and cultural life of people.

Abstract (sommario):

Residential water heaters use a substantial amount of electrical energy and contribute to 25% of the energy usage in the residential sector. This raises concern for users in countries with flat rate electricity fees and where fossil fuels are used for electricity generation. Demand side management of tanked water heaters is well suited for energy-focused load reduction strategies. We propose a strategy for providing an electric water heater (EWH) with the optimal temperature planning to reduce the overall electrical energy usage while satisfying the comfort of the user. A probabilistic hot water usage model is used to predict the hot water usage behaviour for the A*-based optimisation algorithm, which accounts for water stratification in the tank. A temperature feedback controller with novel temperature and energy-correcting capabilities provides robustness to prediction errors. Three optimal control strategies are presented and compared to a baseline strategy with the thermostat always on: The first ensures temperature-matched water usages, the second ensures energy-matched water usages, and the third is a variation of the second that provides Legionella prevention. Results were obtained for 77 water heaters, each one simulated for four weeks. The median energy savings for predicted usage were 2.2% for the temperature-matched strategy, and 9.6% for both of the energy-matched strategies. We also compare the practical energy savings to the ideal scenario where the optimal scheduling has perfect foreknowledge of hot water usages, and the temperature and energy-matched strategies had a 4.1 and 11.0 percentage point decrease from the ideal energy savings.

Abstract (sommario):

Water pollution and drought in the United States have made water scarcity a widespread concern. Currently, residential consumers account for most urban water use, and meaningful programs that lead to water conservation rely on a comprehensive understanding of how consumers use water inside and outside their homes. This 5-page fact sheet outlines University of Florida researchers’ assessments of current US household indoor and outdoor water use to assist policy makers and researchers with creating incentives for homeowners to conserve water.

Abstract (sommario):

Cambodia is one of the poorest countries in Asia and the mortality and morbidity due to lack of improved water supply sources are high. Improvement in this area could better the situation for many Cambodians and as a consequence better the situation for the state of Cambodia.

The purpose of this thesis is to depict how water issues are being handled in Cambodia. This is done from an anthropological point of view and as a result the focus is on the interviewees of this study. Issues that will be of interest are water consumption and management behaviour, and their explanations. Thoughts and knowledge on water treatments, water safety and how to prevent water related health issues will also be of interest. Other important aspects are sanitation, garbage and the work of non-governmental organizations and the Royal Government of Cambodia. The field work was carried out though interviews and observations in three main areas, urban Phnom Penh, Khsach Kandal and Angk Snuol.

The result focuses on risk behaviour and behaviour change and shows that there is a lack of knowledge among the people I talked to when it comes to water related health risks. There is a big mistrust in the quality of the water and most people regard boiling a necessity before drinking the water. However, storage is generally the big problem as well as lack of information on how, where and why water gets contaminated.

Another problem that emerged is that there is a lack of financial commitment from the Royal Government of Cambodia and much work is done by NGOs which might be the reason for conflicting and confusing messages towards the public.

Kambodja är ett av Asiens fattigaste länder och bristen på tjänliga vattenkällor gör att skade- och dödstalen är höga. Framsteg på detta område skulle förbättra situationen för många kambodjaner och i förlängningen förbättra situationen för Kambodja.

Syfte med studien är att beskriva hur problem kring vattenkonsumtion hanteras i Kambodja. Studien har en antropologisk utgångspunkt vilket betyder att fokus ligger på informanterna och deras berättelser. Frågor som var av intresse vara vattenkonsumtion och vattenhanteringsbeteende samt förklarningar kring dessa. Tankar och kunskap kring vattenrening, vattensäkerhet och hur man förebygger vattenrelaterade hälsoproblem är också av intresse för studien. Ytterligare viktiga faktorer är hygien- och avfallsfrågor, samt arbetet som hjälporganisationer och Kambodjas regering utför. Fältstudien utfördes genom intervjuer och observationer i tre områden: Phnom Penh, Khsach Kandal and Angk Snuol.

Resultatet av studien fokuserar på riskbeteende och beteendeförändring och visar att det finns kunskapsbrister när det gäller vattenrelaterade hälsorisker bland mina informanter. Det finns ett stort misstroende när det gäller vattenkvaliteten och det flesta ser kokning som ett måste innan de kan dricka vattnet. Generellt sett är dock vattenförvaring ett större problem tillsammans med en brist i hur, var och varför vatten blir förorenat.

Ett annat vattenrelaterat problem är brist på ekonomiskt åtagande från den kambodjanska regeringens sida. Mycket av arbetet utförs av olika hjälporganisationer vilket kan vara anledning till den ibland motsägelsefulla och förvirrande information som ges till allmänheten.

Abstract (sommario):

Investigation and research into the Persian Gardens, leading this project into a step that these World Heritage Sites might have been known as sustainable construction, but the fact that water scarcity of their region is a serious threaten for all these amazing Gardens. Thus, enhancing and improving these gardens by merging, adding and adapting todays technologies can make them considered as constructions with water and energy conservation design. Based on nowadays world environment concerns, recognizing renewable and non-renewable sources of energies in a region or site can cause a miracle. Since, almost all Persian Gardens located in regions with arid and semi-arid climate, water poverty as a biggest issue and nonrenewable energy should be included as a problematic concern. There are many available active and passive strategies that can be applied in these heritage sites which decrease water consumption either directly or indirectly. Such as water harvesting, greywater reuse, photovoltaic panels and material changes. Water known as a vital element of each garden for irrigation purposes, but in Persian Garden water is more than a functional element. Thus, finding a way to provide and recycle water beside the underground sources is necessary. Subterranean, springs and wells are resources of water for Persian gardens which renew so slowly or non-renew these days. Being so close to a city with considerable population lunches and idea of using greywater for irrigation in these gardens. In this research, the doable options for energy conservation design for these sites will be discussed, then comparing some case studies in all over world where greywater reusing water system for irrigation is happening will be next step. In conclusion, greywater reusing system in urban scale in order to irrigate a filed or garden will be investigate on a Shazdeh Garden as a main case study of this research.

Abstract (sommario):

Both the increasing demand for comfort levels and growth in population are facts that assure that the energy demand in buildings will keep growing in the future. Heating, ventilation and air conditioning systems (HVAC systems) are the principal users of this total energy demand, where percentages over 50% have been reached. Air conditioning is essential to maintain the thermal comfort inside the buildings, and for this reason, innovative cooling systems should be analysed in order to reduce and improve energy usage of these systems. The aim of this thesis is to explore the viability and limitations of a new chilling system that uses tap water as a cooling source. The project has been focused on a building owned by an insurance company in Gävle, where a cooling system has been designed to satisfy the cooling need for an extremely hot day in summer. Water is taken from the main pipe and, via a heat exchanger, it absorbs heat from the chilling circuit. The destination of the tap water, once has been used, has been discussed proposing 3 different options: deliver it to the waste, bring it back to the tap water network and reuse it for hot tap water. Later, based on the results, an overview of the system has been done pointing out the weak and strong parts. When implementing this new system it has to be taken into account that cooling capacity is limited and extra requisites and limitations have to be accomplished since drinking water is used. The most energy efficient design is reusing the water for hot tap water use, since less heat will be needed to warm it up. However, if water is wanted to be reused it should not exceed 15 in order to avoid an environment where legionella could grow and become a health human threat. A suitable situation for this system would be for building which needs cooling and has a high hot tap water demand.

Abstract (sommario):

Thesis (MTech (Electrical Engineering))--Cape Peninsula University of Technology, 2009
This study presents an intelligent Hot Water Cylinder (HWC) usage profiling system to provide peak demand side management and improve HWC efficiency in a typical household. In this research HWCs will be referred to as geysers. Research was done into various techniques available to improve energy efficiency in South Africa, as well as the different sectors South Africa's electricity supplier, Eskom, has highlighted where improvements in energy efficiency can be made. From this it was decided to refine the scope of the project to the residential sector, and more importantly geyser. A typical geysers operation and power consumption was researched and analysed to determine where efficiency improvements could be made. A system was required that would reduce the amount of energy consumed by the geyser, and provide the consumer with hot water at the same time. Based on the research it was decided to design a profile based geyser controller. The profiling system comprised of a PIC microcontroller, four digital temperature sensors and a time keeper used to determine individually based hot water usage profiles for the home. The profile was based on three parameters, namely the frequency (repetitiveness) of hot water being drawn, the length of the draw period, and the time of day when the water was drawn. Once the profile had reached a 90% accuracy, the profile implemented itself. Based on the profile, the controller then regulated the temperature of the geyser according to the demand of the household, without manual intervention. If the household's routine were changed, the profile would adapt itself accordingly. The controller is therefore fully intelligent and continues to refine the profile on a day to day basis. By introducing the profile based controller, the monthly average geyser temperature was reduced, reducing the amount of standing losses, which in torn reduced the total amount of energy consumed by the geyser. The profile controller was designed to aid in the reduction of the energy demand of geysers on the power grid. This will benefit both the consumer as well as Eskom, as Eskom will have a reduced power load, and the consumer will have a reduced electricity bill. The results of the experiments are shown, as well as a comparison between calculated versus measured results, to justify the accuracy of the calculations.

Abstract (sommario):

This thesis reports on the research undertaken to reduce the water usage within manufacturing through modelling and improving the water efficiencies at both process and production system levels. The primary objectives of this research are: to develop a framework which classifies the various water usages within a manufacturing facility, to define a number of efficiency ratios to highlight the water inefficient activities, and to develop a decision support tool to aid with the selection of the most effective solutions for reduction of water usage within manufacturing applications. The research undertaken in the past three years is divided into four main parts. The first part reviews the relevant literature on water availability and distribution, the role of water in manufacturing, and relevant legislations and policies governing the water usage in manufacturing industries. The review also includes assessment of current water flow modelling and wastewater management tools and technologies. The second part introduces a Manufacturing Water Usage framework which classifies the water usage within a manufacturing facility as production-related and non-production-related water. The Production Water, which is the main focus of this research, is further classified as Process and System Water required to produce a product. Process Water is defined as the water used directly by the production processes, whereas System Water is defined as the water used to support the operation of a process and/or to maintain the production equipment. The framework also incorporates the definition of a number of Water Efficiency Ratios to determine the water critical processes. The third part of the thesis describes the implementation of this framework within a water simulation model as the main engine for a water reduction decision support tool. The final part of the thesis demonstrates the utilisation of this tool to support the decisions aimed at reducing water within a real food production line. In summary, the research has concluded that the consideration of water reduction scenarios within the manufacturing industry requires a detailed understanding of where and how water is used at production process level, and utilisation of this knowledge to develop a series of proactive approaches based on product/process redesign and radical operational planning improvements.

The importance of public acceptance within the decision-making process for large-scale, municipal water projects is widely understood and documented. In order to assess the role of public perception on the acceptance of alternative water sources, this paper broadly evaluates public preference for alternative water source and water conservation programs through a user-based approach. Choice-based conjoint analysis was utilized as a quantitative method to determine which design attributes make alternative water sources, specifically desalination and recycled water facilities, more appealing to communities. An online survey was taken by 306 respondents in California, Florida, and Texas. Respondents were analyzed on an aggregate level to identify overall perception of, familiarity with, and preference for desalinated and recycled water. The results indicate significant importance placed on specific attributes such as cost and environmental impact, as opposed to the water program type and location of the proposed facility. Findings based on subpopulations of respondents suggest that preference between water program types were fairly consistent among different demographics, but varied on characteristics such as increased familiarity and perceived reliability of currently provided tap water.

Abstract (sommario):

The exponential growth of the world population led by the geographic expansion of urban areas in developing countries has put massive pressure on natural resources especially land and water. Water supply and water scarcity remain one of the major challenges facing the industrializing world. The United Nations forecast further increase in population which, in the absence of management and policies, will inevitably put more resources at risk. Changing climatic conditions causing more frequent and intense rainfall will also affect water management systems in the vulnerable urban areas of developing countries. The goal of this study was twofold; first analyze the patterns of water consumption in the rapidly growing city of Lagos, Nigeria and use them in a System Dynamics (SD) model to make projections about future demand. The second part used remote sensing to quantify the contribution of extensive land use/cover change to urban flooding. Land use/cover dynamics over the past decade was analyzed using satellite imagery provided by Landsat Thematic Mapping (TM). Unsupervised classification was performed with false color composite using the Iterative Self-Organizing Data Analysis (ISODATA) technique in a Geographic Information Systems (GIS). The study area was divided into four different land use types during image classification: bare land, built-up area, water bodies, and vegetation. For water demand, two different scenarios of population growth including 5.5% and 2.75 % annual increase were considered. The results showed that water demand dropped by 67% of its current value when losses in distribution were reduced by 20% and population annual growth rate kept at 2.75% over the study period. Bare land and water bodies lost 1.31% and 1.61% of their current area respectively while built-up area grew by 1.11%. These changes in land use/cover changes led to a 64% increase in average surface runoff, mostly attributable to increasing surface imperviousness and the absence of an adequate urban drainage system. This paper intends to assist the authorities of the city of Lagos who adopted a master plan in 2010 as a road map to reduce to city’s vulnerability to flooding and close the gap between water demand and water supply by 2050.

The goal of this thesis is to explore the design of a reusable water bottle that can be inverted to expose the inside. Being able to directly touch the entire inside of the product could facilitate cleaning and consequently promote sustainable water bottle usage. Existing cleaning solutions and various water bottles were evaluated for benchmarking, and a water bottle usage survey revealed that most respondents clean their reusable bottles on a weekly to monthly basis, with 35.5% of respondents indicating that they had thrown out a bottle since it was clean. Observing volunteers in water bottle cleanliness perception test revealed that being able to physically contact and see the inside of the bottle while cleaning were most important. Two iterations of sketch models were created, demonstrating that a pouch-like design with a drawstring attached between the inside of the pouch and the water bottle top to aid invertibility was the most feasible solution. The final water bottle design, created as a CAD model, consists of three components: a top, a bottom, and an invertible pouch made of a soft plastic. The invertible pouch is held in place and made watertight between the bottom and top components that resemble a standard reusable water bottle design.

Abstract (sommario):

Climate change can have a large effect on thermoelectric power generation. Typical thermoelectric power plants rely on water to cool steam in the condenser in order to produce electricity. Increasing global temperatures can increase average water temperatures as well as decrease the amount of water available for cooling due to evaporation. It is important to know how these parameters can affect power generation and efficiency of power systems, especially when assessing the water needs of a plant for a desired power output and whether a site can fulfill those needs. This paper explains the development of a model that shows how power and efficiency are affected due to changing water temperature and water availability for plants operating on a Rankine cycle. Both a general model of the simple Rankine cycle as well as modifications for regeneration and feedwater heating are presented. Power plants are analyzed for two different types of cooling systems: once-through cooling and closed circuit cooling with a cooling tower. Generally, rising temperatures in cooling water have been found to lower power generation and efficiency. Here, we present a method for quantifying power output and efficiency reductions due to changes in cooling water flow rates or water temperatures. Using specified plant parameters, such as boiler temperature and pressure, power and efficiency are modeled over a 5°C temperature range of inlet cooling water. It was found that over this temperature range, power decrease ranged from 2–3.5% for once through cooling systems, depending on the power system, and 0.7% for plants with closed circuit cooling. This shows that once-through systems are more vulnerable to changing temperatures than cooling tower systems. The model is also applied to Carbon Plant, a coal fired power plant in Utah that withdraws water from the Price River, to show how power and efficiency change as the temperature of the water changes using USGS data obtained for the Price River. The model can be applied to other thermoelectric power stations, whether actual or proposed, to investigate the effects of water conditions on projected power output and plant efficiency.

Abstract (sommario):

The author undertakes a literature review of attitudes to water usage in Jordan. One survey was identified which assessed attitudes towards water conservation, sampling 2000 residents in three regions in Jordan (Irbid, Amman, and Zarqa) in 2017. According to the survey, only 61% of respondents believed there was a water shortage in Jordan. 23% believed the water shortage was due to population pressures. The survey focussed more on water conservation than water use. Most of the respondents felt the government were not doing enough on water shortage issues. They were not asked how they feel about the role of the government versus their individual responsibility. Older respondents perceived the shortages to be more critical. A lack of interest in participating in water saving activities was identified among the youth. Water quality was perceived as poor in the USAID survey and noted in other sources. The survey found that most residents had management strategies in place for the day that the water was delivered. Views about politics of regional cooperation and refugee pressure on water use potentially affect attitudes to water but this was not identified specifically within the scope of this report.
