Opis:
The increasingly frequent use of computer simulations for the calculations concerning the water supply systems requires accounting for the demand patterns. Determining the coefficients of daily and hourly non-uniformity is indispensable for the correct designing or modernization of pipes in the water supply network. The first goal of article was to obtain the non-uniformity index for the preparation of hydraulic models in rural water systems called "N" system and "CWK" system. In this article, the authors present the results of the water consumption analysis in two rural water supply systems. The article presents the water consumption non-uniformity factors calculated over the course of a year, a month and a day. The article also included the calculated water demand curves over the course of a day, showing the variability of water demand with characteristic morning and evening water consumption peaks and changes of the consumption curve in the prospective development of the water supply network, where industrial consumers would become the main water consumers. The research material consisted of the water consumption measurements in two rural water supply networks situated in northeastern Poland, taken over the years 2010-2017. The article also shows the water demand curves in the studied rural water supply networks for every day of the week. The values of minimum and maximum hourly non-uniformity coefficients were compared to the mean value of these coefficients. The changes in the values of minimum and maximum hourly coefficients with respect to the mean value for the given hour may differ from -89% to +85% for hours of minimum demand. The changes in the values of minimum and maximum hourly coefficients with respect to the mean value for the given hour may differ from -16% to +30% for hours of maximum demand.

Opis:
This article presents the analysis of the water supply system expandability in the commune of Mściwojów. Such necessity of the expansion resulted from the locations of the new investments covered by the pilot program VITAL LANDSCAPES. Hydraulic calculations, covering two possible solutions, have proven that the existing water supply network is sufficient now and will be sufficient in the near future (after expansion), in supplying all the consumers with water.

Opis:
The topic of failures and water losses in the urban-rural water supply network was discussed. The purpose of the work was to assess the level of real water losses and the failure rate of the urban-rural water supply network in 2010-2016. The article’s introduction contains the information on the types and causes of breakdowns in the water supply network. The life cycle of the leakage from its inception to its removal was also described. Next, the methodology and indicators for assessing actual losses in the water supply network were presented according to the guidelines of the International Water Association (IWA), i.e. ILI, CARL, UARL, RLB and water balance. The material and methods chapter describes how to calculate the failure rate. On the basis of the literature review, a method of assessing the failure of the water supply network and the level of actual water losses was presented. The research part presents the results of the water losses indicators values and assesses them against the literature data for the entire urban-rural system. The results of the failure of the water supply of the urban area and the rural area were also presented and compared with the literature data. A method of calculating limit values of the failure intensity index for the entire water supply system was also proposed. The changes in the intensity of failure occurrence during the year were presented. The object described in the studies achieved the A rating according to the classification of ILI and RLB values throughout the entire analysis period (2010–2016). Failure intensity in the analyzed period exceeded the average values calculated for water supply networks in Poland many times. The values in individual cases exceeded the limit values specified in the literature.

Opis:
Consistent access to potable water remains a major challenge among communities in rural areas of Vhembe District Municipality (VDM). This is due to the high frequency of water supply infrastructure breakdown due to obsolete infrastructure and inadequate involvement and participation of rural communities in paying for water and maintenance which affect sustainability of water supply system in VDM. This study assesses current state of water supply, challenges and effectiveness of measures in place in order to propose intervention to improve rural water supply system in VDM. The study followed a mixed method research design, which include both qualitative and quantitative methods. Data was analysed using thematic content analysis and chi-square test. The study established that water is inconsistently supplied in VDM. As about 53.5% of the respondents received water once per week which necessitate intervention to improve the situation. All the respondents from the four local municipalities of Vhembe District were not satisfied with the quantity of water received and distance travelled to collect water. The study recommend intervention strategy which included that local management structure to be established and terms of reference agreed with communities including more water supply sources options to be added

Opis:
Access to clean and sufficient drinking water is difficult in much of Ethiopia’s Afar Region. It is observed that many schemes in the region are non-functional. The study was conducted to overcome the observed problem in seven selected districts of the region. The study regarded hand-dug wells and roof water collection systems, which are the two most common features in the research areas. Eight hand-dug wells and sixteen roof water harvestings are purposively included in the study. All the water points are constructed by Kelem Ethiopia which is a non-governmental organisation and the foremost local organisation for the communities. As per the research survey, the average functional status of the hand-dug well schemes is 65.75% and the roof water harvesting schemes is 22.94%. The research was based on the qualitative data collected on site. The hand-dug well sites were evaluated using 10 parameters, and the roof water harvesting schemes were analysed using 12 parameters. The main non-functional aspects of the scheme are lack of community ownership, drying up of water sources, lack of maintenance and rehabilitation, poor coordination of beneficiaries and school roofs blowing off. Most schemes still require minor to major maintenance and rehabilitation. According to the research, the solutions for water supply are identified in relation to the desired objective.

Opis:
The paper presents the development of water supply networks and sewage systems in rural areas of Małopolskie and Podkarpackie Voivodeships in the Polish context. The scope of the thesis includes the analyses of length of water supply networks and sewage systems, number of people using them, number of water and sewage connections and volume of used water and volume of discharged sewage. The results of the study were presented in the graphs. The research material was taken from the reports on municipal infrastructure published by The Polish Central Statistical Office (GUS) for 2002-2012 and Local Data Bank (BDL) for 1995-2001. Though there has been a significant improvement in water supply and sewage systems, Poland will have great difficulty in meeting the requirements concerning their development in rural areas by 2015.
