Water is indispensable for life. Although it is abundant on earth, only 3% of it is freshwater and it is not distributed evenly over the world. Distribution of fresh water is unfortunately not linked to the distribution of population. This means natural water resources are not available in every human settlement. Furthermore, some of existing natural water resources are managed inappropriately, for instance in poorer underdeveloped or developing nations water resources might get polluted due to lack of sanitation systems, whereas in developed countries same is true if there is a lack of enforcement of environmental policies. Thus, firstly existing water resources need to be saved with basic investments to achieve Millennium Development Goals (MDGs), some of which are directly related to the solution of water scarcity problem. Then, for the rest of water scarce countries, evaluation of alternative methods to supply water demand, which are called alternative water supply systems, is compulsory. However, these systems are expensive compared to regular water supply systems. Thus, for a water poor country, financial comparison of alternative water supply systems has great significance. This study aims to compare those alternative water supply systems financially over a case study on Avşa Island, Turkey. For the island, three alternative water supply systems are considered. Two of these require purchasing water from a nearby municipality on the mainland and the third option investigates the possibility of a reverse osmosis plant to convert Marmara Sea water to potable water. Financial comparison of these alternatives reveals that the most viable option for Avşa Island is to build a reverse osmosis plant.

Economic feasibility assessment of solar powered seawater desalination plants: Unconventional fresh water supply for Guzelyurt, Northern Cyprus
Oner, Hüseyin; Fahríoğlu, Murat; Sustainable Environment and Energy Systems (2019-9)
Water is essential for living beings. Without the existence of water, we would not have existed or progressed. Therefore, throughout the history of mankind fresh water supplies have been considered as a strategic resource for prosperity. Nowadays, many researches indicate that due to climate change, fresh water supplies around the globe are expected to become scarcer and more unpredictable which would eventually become a major challenge for our society. One of the earliest energy sources for desalination or...
WATER SENSITIVE URBAN DESIGN: A TRANSFORMATIVE APPROACH AS PART OF THE URBAN FORM
Sözer, Tuğçe; Akkar Ercan, Zübeyde Müge; Urban Design in City and Regional Planning Department (2022-1-21)
Water is life, and life on earth depends on water or suffers from lack of it. Although it is not a new phenomenon, water issues are still critical socially, economically, and environmentally. It is not just a natural source but also has a significant role in the urban water cycle. Water is a renewable but finite resource that is under increasing pressure to meet the demands of climate change, rapid urbanization, neoliberal policies, and unequal distribution since it is perceived as an infinite source and a ...
The forgotten value: a study on the restructuring urban fabric with water
Gürsan, Hand; Barlas, M. Adnan.; Urban Design in City and Regional Planning Department (2019)
Water is regarded as a vital element in almost all contexts in the world. From early times, it has a significant role in both in nature and urban settlements. People from the past to the present have always dealt with the water issue for their needs. Basically, they are constantly trying to reach clean water in this process. Together with individuals in the society, the perception of water in cities and in countries have been changed in today's world. Generally, water is used in the urban areas for municipa...
Rehabilitation of water supply systems
Toğrul, Nevzat; Merzi, Nuri; Department of Civil Engineering (2015)
Management of water supply systems by an economic and efficient way is a significant issue for water authorities. Selection and operation of water supply elements appropriately to satisfy water need affects the energy consumption of the system. This study aims to constitute a long term rehabilitation plan for water supply elements (only storage tanks, pumps and transmission line pipes are in the scope of the study). A case study has been performed on N8.3 pressure zone of Ankara water distribution network. ...
Turkey’s transboundary water policy : dominance of the realist paradigm?
Yakar, Funda; Bölükbaşıoğlu, Süha; Department of Middle East Studies (2013)
Water is the most vital natural resource on the earth both for human and other species to survive. However, water is a scarce resource like other natural resources. Along with its essentiality for living things and natural life, water has been a key element for development in recent years. Rapid population growth, industrialization, global warming and climate change exacerbate water scarcity and water related conflicts especially in arid and semi-arid parts of the world. Therefore, water problem increasingl...
