This article aims to analyze the implementation of state obligations and responsibility ensuring the availability of clean water as part of human rights in Karimunjawa islands. The analysis based on principle of the State obligations and responsibility to fulfill their citizen right. Water sources in Karimunjawa Islands is very limited. It depend on forest conservation. Around 9.600 peoples live in Karimunjawa Islands, but Karimunjawa is non groundwater basin region. It means, Karimunjawa doesn’t have groundwater potential. The quantity of water depends on the season. The solution to maintain the sustainability of clean water is piping from water reservoir to residential areas. The problem is there are so many hotels in Karimunjawa islands, it disrupted the fulfillment of clean water. Besides utilizing water from reservoir, many hotels drilled the ground to get water. It had impact to the availibity of water in dry season and affected to fulfillment of water supply for Karimunjawa people. There is no specific regulation and policy to solve this problem. Clean water management is doing by Karimunjawa’s people. Meanwhile, based on Mahkamah Konstitusi Decree number 85/PUU-XI/2013, state is a rights holder to dominate the water in accordance with the Articles 33 paragraph (2) and (3) UUD NRI 1945, so the government has an obligation to make a policy, regulations, management, and supervision.

With the vision of "Realizing Students Who Are Excellent in Achievement, Skilled, Praised in Character and Cultured in an Environment Based on Faith and Faith" SMP Negeri 22 Malang is located in the eastern area of Malang City, bordering the Malang Regency area, precisely in the hilly area of Villa Gunung Buring, Kelurahan Cemoro, the enclosure of Kedungkandang District, Malang City. This school was founded on October 20, 1999, with a land area of 5,597 m2 with a total area of 2,160 m2 consisting of 36 rooms, the number of study groups is 20 classes, each 6-7 study groups, the total number of students is 610 people and is supported by 35 educators. person. As we know above, with a large enough number of teachers, employees and students, it needs quite a lot of clean water. Whereas the water source at the school is obtained from the distribution of water from the housing whose discharge is very small, so it requires a water reservoir to accommodate water, currently the school only has a water reservoir above with a small volume capacity with a small pressure so that the water is unable to meet even though it has been assisted by a pump due to small water discharge.For this reason, the school has a plan to make an underground water reservoir with the aim of storing water which is then raised to the upper reservoir with the help of a pump, that the water reservoir planning is carried by the ground.

The Impact

The limitedness of area and plot of land in Jayapura City which are allocated for settlements has become a problem in Jayapura city. Population growth and high-rate of urbanization are impacted on the utilization of land which is not in accordance with its allocation. The modification of riparian area on the right and left sides of the river for settlements has reduced the function of the river, because in addition to river conservation, river has a double role as the securer of water source and as the protector of its surrounding area. Therefore, riparian area becomes more important to be considered. The riparian area in settlement area is assumed to be adequate for a 10-15 meters inspection road to be built on. The real condition of the rivers in North Jayapura District of Jayapura City, compared to the criteria of riparian area for settlement area, has not been inappropriate. The river’s function as the protector of its surrounding area has gone astray. If there is someday a flood, the impact may cause material damage or even life victims.

При изучении качества воды источника водоснабжения г. Самары Саратовского водохранилища особое внимание было уделено основным показателям, влияющим на выбор реагентной обработки: мутность, перманганатная окисляемость и цветность. Сезонные изменения качества воды водохранилища требуют постоянной корректировки дозы реагентов с целью достижения нормативных требований к качеству очищенной воды. Приводятся результаты производственных исследований изменения качества воды Саратовского водохранилища в створе водозаборов г. Самары за 20172019 годы по мутности, перманганатной окисляемости и цветности. В связи с аномальными температурными перепадами и наступлением осеннего паводка (конец декабря 2019 г. и январь 2020 г.) резко изменилось качество воды водохранилища по цветности и перманганатной окисляемости. Отмечено, что увеличение указанных показателей потребовало повышения дозы реагентов при очистке исходной воды. Оптимальная доза реагентов постоянно коректируется в зависимости от состава исходной воды на флокуляторе Lovibond ЕТ-750 . Регулярное проведение пробного коагулирования позволило поддерживать качество очищенной воды в соответствии с нормативными требованиями СанПиН 2.1.4.1074-01 Питьевая вода. Контроль качества , кроме цветности и железа общего, так как превышение этих показателей наблюдалось в пределах погрешности методов измерения.While studying the water quality of the water source of the city of Samara the Saratov water reservoir, special attention was paid to the main indicators that influence the choice of chemical treatment: turbidity, permanganate index and color. Seasonal changes in the water quality of the water reservoir require constant adjustment of the chemical dose in order to meet the regulatory requirements to the quality of treated water. The results of the studies of changes in the water quality of the Saratov reservoir at the water abstraction points of the city of Samara for 20172019 by turbidity, permanganate index and color are presented. Due to the abnormal temperature differences and onset of autumn flood (end of December 2019 and January 2020), the water quality in the water reservoir dramatically changed in color and permanganate index. It was noted that an increase in these indicators required an increase in the dose of chemicals during the source water purification. The optimal dose of chemicals is selected with Lovibond ET-750 flocculator depending on the composition of the source water. Regular test coagulation allowed maintaining the quality of purified water in accordance with the regulatory requirements of SanPiN 2.1.4.1074-01 Drinking water. Quality control , except for color and total iron since the values of these indicators were increased within the measurement accuracy.

This paper demonstrates the statistical approach for describing failures and lifetimes of water mains. The statistical approach is based on pipe inventory data and the maintenance data registered in the data base. The approach consists of data pre-processing and statistical analysis. Two classes of statistical models are applied, namely counting process models and lifetime models. With lifetime models, one can estimate the probability which a pipe will fail within a time horizon. With counting process models one can see the deteriorating (or improving) trend in time of a group of “identical” pipes and their rates of occurrence of failure (ROCOF). The case study with the data base from Trondheim municipality (Norway) demonstrates the applicability of the statistical approach and leads to the following results: 1). In the past 20 years, Trondheim municipality has experienced approximately 250 to 300 failures per year. However, the number of failures per year will significantly increase in the near future unless better maintenance practice is implemented now. 2). Unprotected ductile iron pipes have a higher probability of failures than other materials. The average lifetime of unprotected ductile iron pipes is approximately 30 to 40 years shorter than the lifetime of a cast iron pipe. 3). Pipes installed 1963 and 1975 are most likely to fail in the future; 4) The age of a pipe does not play a significant role for the remaining lifetime of the pipe; 5). After 2 to 3 failures, a pipe enters a fast-failure stage (i.e., frequent multiple between failures).
