Since the end of 2019, 92.1% of rural households in Hai Phong city had been able to access and use clean drinking water, which meets national standards as a result of developing a clean water supply system consisting of 205 plants with various management models. The authors applied the desk-study method to collect and review literature research, select a group of six criteria, and then applied the criteria to assess the system's sustainability based on Likert's 3-point scale. The results show that criteria scores ranged from 1.9 points to 2.5 points, while the total score of the whole system is 12.9 points - reaching an average sustainability level. The authors propose that in order to improve the sustainability of the clean water supply system in the rural areas of ​​Hai Phong city in the future, management agencies and investors need to apply a solution of propagating rural people to increase their usage volume of clean water, which will help to increase the actual operating capacities of the plants, thereby increasing the revenue and profits of plant investors.

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

Abstract This study aimed to present a methodology for locating water distribution reservoirs in rural Andean areas (isolated areas, low-income population, mountainous region). The research methodology consisted of the following steps: (1) description of the problem; (2) development of the DR location protocol; (3) obtaining an algorithm; (4) calibration and adjustment; and (5) application. The obtained algorithm was based on the classification and overlapping operations of five-parameter maps (pressure limits – pressure in the water supply system from 5 to 40 mH2O; supply by gravity – guarantee of gravity as energy for water movement; accessibility – use of unprotected areas or with restricted occupation; stability, greater distance from geological fault; and, proximity to population concentration, shorter distance between population centres). The overlapping of these parameters enabled us to identify a region of candidate points and select the best location point for the reservoir. The algorithm was applied to a real case indicating satisfactory results. A methodology for locating water distribution reservoirs in rural areas that have important economic constraints, difficult access (mountainous region) and high geospatial dispersion was found. Improvements in methodological steps can still be considered, for example, forecasting the use of pressure control devices in the water supply system.

Water Network

CWSS in Kotamobagu has various problems such as, pipe water network that has not been operated optimally since its completion in 2012. The number of house connections was merely 424 out of 7,600 targeted until 2016. Other problems in Kotamobagu were related to the supply, backwash, insufficient electrical power supply, no water meter, reservoir leakage, and intake pipes leakage in Poyowa and Bilalang. This research aims to find the root of the problem in terms of Clean Water Supply System (CWSS)'s network system, organization, regulation, and management. The research focused on Poyowa Besar's CWSS and Bilalang-1's CWSS networks in Kotamobagu. The research methods included observation, survey, and policy analysis where respondents were required as sources of information. The respondents were from Sia's and Pontodon's CWSS that represented 162 house connections. Additional respondents representing 30 house connections were selected randomly at Poyowa Besar's and Bilalang-1's CWSS for comparison. The results indicated that the community, CWSS managers, and the Central Government support the existence of Kotamobagu CWSS management. The 30 house connections at Poyowa Besar's and Bilalang-1's CWSS have never been served with water, but the respondents positively hope that the matter will be solved in the near future. They were willing to keep waiting for the water network of Kotamobagu's CWSS. The root of the problem in the Poyowa Besar's and Bilalang-1's implementation was due primarily to a network system that was built by the Ministry of Public Works for the Municipal Government of Kotamobaguwas reportedly not in accordance with procurement regulation. There was disagreement between the Ministry of Public Works and Housing (MPWH) and the CWSS managers related to the items that have to be fulfilled for network infrastructure handover.

SUMMARYA case-control and a case-crossover study were performed to investigate a Campylobacter jejuni outbreak in Crete in 2009. Most cases originated from rural areas, served by a different water-supply system from that of the adjacent town. Thirty-seven cases and 79 controls were interviewed; cases were interviewed for two different time periods for the case-crossover study. Stool cultures, PFGE and MLST subtyping were run in human samples. Univariately, consumption of tap water was associated with C. jejuni infection. Stratified analysis revealed that water-supply system was an effect modifier of this association. In the multivariable analysis, the rural areas' water supplier and drinking tap water were risk factors. No risk factors were revealed in the case-crossover study. No Campylobacter were isolated in the tested water samples. There is strong epidemiological evidence that tap water was the vehicle of the outbreak.

Planning for a clean water supply system is a community service program carried out by USU in collaboration with the Dinas Pemberdayaan Masyarakat dan Desa(PMD) of the Pemko Tebing Tinggi. The problem encountered is the unavailability of clean water. This condition can interfere with people's daily activities such as the need for households. The clean water supply system that is implemented is the application of appropriate technology in the sense that it is easy to operate and all components are easy to care for by the public. The purpose of this activity is to provide clean water that meets health requirements, namely colorless, tasteless and odorless. This system is also planned to provide clean water for the next few years. The projection of population growth is also a consideration, which is calculated based on the average population growth data. Based on the Indonesian National Standard (SNI), the need for clean water for a population with a population of 300 households with the household category is 120 liters per person per day, so the water requirement is 1.67 liters/second. The source of water is obtained by digging 15 meters deep by installing 15 concrete rings with a diameter of 80 cm and a height of 100 cm. Then a pump is installed to suck water and then it is pumped into a poly tank (capacity 2100 liters) storage tank which is located at a height of 5-6 meters. Before flowing from the tank  to the pipe, the water is filtered using a filter. For this purpose, a piping installation complete with a valve and a float is designed to automatically close the pipe when the tank is full. The result of water from this system is clean water and suitable for consumption by residents.

During the dry season there was a scarcity of the availability of clean water in several Central Java province (Wonogiri, Sukoharjo, Karanganyar Disrict and Surakarta City), including Wosusokas Regional Region, so the government often drops clean water. So, the Government conducted the Wosusokas Regional Water Supply System Program. Public-Private Partnership (PPP) scheme is an option to overcome investment cost. This study aims to identify and analyze the risks of Wosusokas regional water supply system project eith government perspective. This research adopted a case study and literature analyze. Selected respondents from PDAB Tirta Utama, Dinas Bina Marga dan Cipta Karya Central Java, BPPW Central Java, District/ City Governments (Regional Water Supply Company, Bappeda and DPU) from Wonogiri, Sukoharjo, Karanganyar and Surakarta. The result found 35 risk factors that could potentially project failure or delay, the majority of these are considered high (11,43%), moderate (54,29%) and low (34,29). Risk factors with high probability are delay and increase cost of land acquisition, failure to complete the contract by the contractor / sub-contractor, failure initial tariff and delay periodic tariff adjustments. The results are useful for Government as a reference in managing the risks of PPP Spam Regional especially in Central Java.
