We hold that potential natural water use in urban areas must be improved to develop an environmental water supply system (EWSS) for disaster prevention. Such uninterrupted water supply systems could protect cities with large numbers of wooden structures from fire due to earthquake and preserve the urban water environment. Our research focused on two examples of water supply system projects -- a gravity-based water supply system in Shirakawa-go and an open irrigation channel system in Kanazawa City, We propose planning and management with the research results of two examples for model projects in Kiyomizu as an important historical district in Kyoto. The EWSS concept opens the way for a sustainable water environment and the restoration of cities while maintaining cultural beauty and safety for the benefit of future generations.

The primary objective of this plan is to consolidate the current water supply system of Korea organized in the unit of city and county into wide area in order to supply the deficient region by fully utilizing the superfluous water volume of neighboring city and county. Furthermore, it also aims to prepare for the penetration of large foreign water supplier into domestic market by securing competitiveness through consolidation of domestic medium and small water suppliers in consideration of the forthcoming market opening. We determined the regions for which supplying system needs to be adjusted by analyze regions with deficient and superfluous water through the forecast of water supply and demand for established life areas. Further, we established plan to utilize the superfluous water volume as an adjust multi-regional water supply system local water supply system such as water supply plan in the life areas, water supply plan between the life areas.

The presence of some chemical compounds at higher levels than maximum permissible concentrations (MPC) in the drinking water, suggests of water resources pollution. In this paper the following elements were analyzed: total arsenic, cadmium, lead, cooper and zinc. Twelve samples of water from the water supply system from the city of Skopje were examined during one year from three different springs. Also, ten samples of bottled water from three producers from the Macedonian market were tested.The determined average mass concentrations of total As, Cd(II), Pb(II), Cu(II) and Zn(II) in the analyzed water samples from the water supply system are 1.35 μg/l, 0.06 μg/l, 0.6 μg/l, 0.9 μg/l and 1,12 μg/l, respectively, and for the tested bottled water, the mean values ranges from 0.56 - 0.83 μg total As / l, 0.053 - 0.056 μg Cd(II)/l, 0.51 - 0.54 μg Pb(II)/l , 0.6 - 0.87 μg Cu(II)/l and 0.68 - 0.8 μg Zn(II)/l water.The following instrumental analytical methods and techniques were used for the analysis of the tested samples of drinking water: flame atomic absorption spectroscopy (AAS), atomic absorption spectroscopy with hydride cеll, electrothermal atomic absorption spectroscopy.The obtained results are shown in tables and graphic form. According to the obtained results a comparative analysis was carried out indicate that it is a water of good quality that can be used in different branches of the process industry.The obtained results in this paper do not exceed the values of the MPC of the Republic of Macedonia prescribed by the legal regulations for the drinking water, which confirm the health safety of the drinking water from the water supply system in the city of Skopje and the packed waters from the Macedonian market in relation to the tested elements.

Institutional Resources

The Kafr El Sheikh Water Supply Project is a comprehensive endeavour to provide the physical and institutional resources for an effective and sustainable water supply system for 2 million persons in a developing rural Governorate in the Delta region of Egypt. The paper describes the aims of the Management Component, the institutional development of an integrated water supply and sewerage company and the main activities to-date. These include training, operational improvements, health education and finance development. Further support is required until all engineering and institutional development work has been completed.
