The early 1920s were a pivotal period in Perth’s water history, marked by conflict over the inadequacies of the city’s water supply. Only a small area of the city had reticulated water; most people relied on wells or rainwater tanks. Water shortages, particularly in new suburbs and higher districts, prompted the Western Australian Government to impose water restrictions. The press, local government authorities, and opposition politicians took the government to task, and officials and householders protested at public meetings. This article analyzes the causes of water shortages, the level of protest, tensions over the governance of the water supply, and the response of the state government. As on America’s west coast in the same period, government decision making was often influenced by rural needs, but the role played by urban householders, with the support of the press and opposition politicians, was paramount in shaping new water supply systems for city dwellers.

Life, health and hygiene all depend on access to a plentiful supply of safe drinking water. Piped water supplies in rural Egypt are insufficient to meet the demands of the existing population. This situation is worsening due to the rapid population growth and failure of existing water supply systems. There are already areas of the country with severe piped water shortages. If corrective action is not taken soon densely populated villages will become vulnerable to outbreaks of waterborne diseases. Immediate action is needed to reverse the deterioration of water supply systems and to improve the benefits gained from capital works investments in the sector. This paper promotes the concept that sustainable water systems in rural Egypt depends on a central government and local unit partnership. Also needed are consumer bodies to determine user needs; local units to be given powers to manage the revenue and expenditure accounts; and the central government to concentrate on setting policies and guidelines, and assisting with the implementation of major capital works.

In water supply systems, pressure management in most cases is proven to be the most cost-effective activity related to water loss control. As an advanced method of pressure control, it is possible to use variable frequency drives for centrifugal pump control. Pressure regulation can be performed with constant pressure or with proportional pressure control. The application of proportional pressure control is particularly applicable in water supply systems as the operating pump performance is constantly adapting the pressure to the actual demand. Along with lower leakage losses, it also results in lower energy consumption and the elimination of non-stationary phenomena, thereby extending the pump lifetime. Therefore, the paper presents a theoretical discussion of the proportional pressure control. Possible savings are shown on the numerical example of water supply system of the city of Velika Gorica.

Introduction. Regulation of drinking water quality is a very important area of health care and improving the quality of life of the population of the Russian Federation.The aim of this work is the development a model for the assessment of the drinking water quality and calculating the share of the population, including urban, provided with high-quality drinking water from centralized water supply systems, taking into account new methodological approaches to the evaluation of the quality of drinking water using the example of water supply to settlements in the Leningrad Region. Material and methods. The data on the organization of centralized cold water supply systems and monitoring systems for drinking water quality and the results of laboratory studies of drinking water quality in the cities of Volkhov, Svetogorsk, Slantsy, Tosno were studied. Statistical processing of the results was performed, the categories of quality of drinking water supplied to the population were determined, the number of the population provided with high-quality drinking water from the water supply system was calculated in accordance with Guidelines 2.1.4.0143-19.Results. In 2018, 100% of the population was provided with quality drinking water only in the city of Slantsy. In the city of Tosno, this index reached of 83.5%. In the cities of Volkhov and Svetogorsk, drinking water was rated as low-quality. But it is worth noting that in the cities of Volkhov and Slantsy laboratory tests were carried out at 2 points, in the city of Svetogorsk - only at the 1 point, which, given the number of residents, is not enough. For an objective assessment of the state of drinking water and the development of measures aimed at improving its quality, it is necessary to increase the number of monitoring points, as well as to include the results of control and supervision measures and production laboratory control conducted by water supply organizations in the volume of laboratory information.Conclusion. The proposed model allows us to assess the drinking water quality in centralized water supply systems and the proportion of the population, including urban, provided with quality drinking water at the level of the water supply system, settlement, municipal district (urban district), subject of the Russian Federation

Water Supply And Sanitation

Federal Democratic Republic of Nepal is a landlocked country located in South Asia. Nepal has made its considerable efforts to improve the water supply and sanitation (WASH) situation in the country by formulating and enforcing a number of WASH policies, guidelines and acts for the last two decades. But WASH situation of Nepal has not been well documented so far. Aim of this article is to describe the situation of water supply, sanitation and hygiene (WASH) in Nepal by analyzing secondary data and information obtained from published and unpublished literature. About 97 of the total population have access to basics anitation facilities and 87 percent access to basic water supply facility. Sanitation coverage is95 percent in six Provinces and below 90 percent in Province no. 2 of Nepal. The momentum of sanitation coverage was accelerated immediately after internalization and implementation of the Sanitation and Hygiene Master Plan in 2011 and Nepal reaches at close to the elimination of open defecation. The gap between rich and poor in accessing to and using toilet facility has been narrowing down due to the nationwide sanitation campaigns. But there is disparity in accessing and using piped water between rich and poor. Only 25 percent of water supply systems are well functioning and 68 percent can supply water to water taps throughout year. One-fourth of the existing toilet facility across the country are poorly constructed that needs to be upgraded. The government should make consolidated and integrated efforts to reduce existing inequity in the WASH sector and enhance the sustainability of water supply and sanitation services.

Modern organized societies require robust infrastructures, among which hydraulic projects, such as water supply and drainage systems, are most important, particularly in water-scarce areas. Athens is a unique example because it is a big city (population 3.7 million) located in a very dry area. In order to support the development of the city, large hydraulic projects had to be constructed during its history and, as a result, Athens currently has one of the largest water supply systems in the world. Could Athenians choose smaller scale infrastructures instead? Analyzing social, technical and economical historical data, we can see that large capital investments were required. In order to evaluate these investments this paper presents a technical summary of the development. An economic analysis displays historical values of these investments in present monetary values. The cost of existing infrastructure is compared to the cost of constructing smaller reservoirs and a model is created to correlate the price of water and the cost of water storage with the size of reservoirs. In particular, if more and smaller reservoirs were built instead of the large existing ones, the cost of the water would significantly increase, as illustrated by modelling the cost using local data.

The article analyzes the topical issue of assessing the reliability of water supply in Kremenchuk, Poltava region, in the zoning of the water supply system. The scheme of the integrated water supply system of Kremenchuk was built to calculate reliability, which reflects the movement of water from the source to the consumers and the main structures of the water supply system. The work of the water supply system of Kremenchuk and its structure is analyzed. In terms of reliability, it is concluded that water pipes are the least reliable element. The statistics on the failures of the water supply systems of the city of Kremenchuk are analyzed. The calculations showed that the actual failure rate for steel pipes d = 1100 mm of water pipes in Kremenchug is 2 failures per 10 km of steel pipe per year, which is 2 times higher than foreign and domestic data. The reliability assessment of both the integrated and district water supply system of Kremenchuk was performed on the failure of water supply systems for both separately connected individual elements. Comparative analysis of reliability of the integrated and district water supply system of Kremenchuk without fail has shown that the zoning significantly increases the reliability of water supply in the Kryukivsky district, and the reliability of water supply of the Avtozavodsky district remains unchanged. In the integrated system in the Kryukiv district, the parameter of the flow of failures was 1/year, that is, about 3 times a year a break in water supply is possible. In the district system, both systems operate independently, which is why everything remains unchanged in the Avtozavodsky district, and the failure flow parameter for the Kryukivsky district is significantly reduced and is: 1/year, which corresponds to a water supply interruption of about once every 2.5 years. Thus, zoning can increase the reliability of water supply in the Kryukovsky district of Kremenchuk approximately 8 times. Keywords: the water supply system, reliability, dependability, zoning.

The issue of rationalizing water consumption and preserving it for future generations is one of the most important indicators of sustainable development referred to in the Agenda 21. This study aims to assess the sustainability of water resources for the city of Erbil in terms of quantity and quality. In this study, the amount of water available in the existing water sources was evaluated and compared with the volume of water demand. The reliability of water sources, especially groundwater, in the selected area was evaluated and confirmed. The study also focused on the management of groundwater by the concerned authorities and the identification of factors that help to develop the sustainability of these sources. The problems facing the management of groundwater and the proposed solutions to solve these problems were also identified. Due to the rapid growth of the populations and lack of both water demand and water supply system, Erbil City required a fundamental evaluation of water supply systems and good planning for future. However, in this study, the assessment was conducted based on the existing data and the accurate archived documents as well. As a result, the study concluded that there have been a lot of problems that should be taken into consideration in order to provide good managing of the groundwater system. It was also observed that there was slightly higher depletion in groundwater table due to poor supplying. This study can be used as a fundamental reference for future investigations especially for those areas having the same problems in sustainable management of the subsurface basins.
