Abstract The rising population and economic activity have induced an increase in the demand for clean water in Buleleng Regency, especially in Sawan, Kubutambahan, and Tejakula District, respectively. The distribution of clean water supply is carried out through house connections and public hydrant by the Water Supply Company of Buleleng Regency with service coverage only reaching 40.09% in 2018. So it is necessary to evaluate and develop plans for the existing clean water supply system to increase service coverage. The evaluation of the water supply system includes an analysis of the availability and demand of clean water based on the population, with a projection for the next 25 years. Analysis of the clean water supply system development plan considers the availability of water resources potential. The evaluation results show that the existing system has not met the water demands in the service area. The development plan carried out to fulfill the demand for clean water is by optimizing the discharge of the Sanih Fountain by 125 liters/second and the construction of the Bungkulan 2 well.

Abstract The Regional Public Company for drinking water in Pemalang Regency is an official agency given the authority to provide and serve water needs in the Pemalang Regency area. Based on the 2020 BPKP, service coverage is still low. Namely, administrative service coverage of 12.74% and technical service coverage of 18.50%, so the service coverage still does not meet the target and achievement of access to decent drinking water. Based on the BPKP 2020-2024, it is necessary to evaluate the management of the clean water supply system, which aims to improve clean water services in the Pemalang City area. Data analysis was done descriptively. The analysis results will describe the clean water supply system management and evaluation based on appropriate standards, regulations, and literature studies. In addition, analysis using the EPANET program is used for SPAM improvement plans. The same is done for the study of raw water availability and water demand until 2030. The evaluation results found that the existing condition of Pemalang City SPAM is still able to supply clean water needs in the Pemalang City area until 2022, and Perumda must have started looking for supplements or additional discharge to meet drinking water needs up to 2030.

Water losses in the water supply network pose a continuous challenge for water companies. Already during designing new networks, the designer assumes that the amount of water demand must be increased by a certain percentage (usually by 10% of the total average daily water demand for municipal and industrial purposes) due to the possible occurrence of water losses. Water loss is meant the difference between the amount of water injected into the network and the amount of water used and invoiced, i.e. that brings income for the water supply company. Proper water metering management helps to limit water losses. This paper presents analysis of the water meter management of urban-rural 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.

Abstract The aim of the study was an cause and effect analysis of water losses in the collective water supply system of the city located in south-eastern Poland. The exploitation data provided by the water supply company from 2012 - 2016 was used for the analysis. The study uses the recommendations of the IWA (International Water Association) for the water balance making and determination of water loss indicators. The values of water loss indicators were compared to international standards and the technical condition of the network was determined. In addition, failure rate analysis of the water supply network was performed based on the failure rate index λ. Based on the performed analysis, it was found that the water supply company should consider renovation or replacement of the main network pipelines to increase the safety level of water supply, reduce the amount of water losses and the company exploitation costs.

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.

Research Period

The aim of the study is to analyse the seasonality of water losses from a collective water-supply system (CWSS) on the example of a provincial city located in south eastern Poland. The analysis was based on exploitation data obtained from the water-supply company for the period 2012–2016. For the analysis of seasonality a method based on average homogeneous sub-periods was used, with a relative seasonality index and the absolute levels of seasonal fluctuations being determined. Water losses from the analysed CWSS are also characterised using unit water-volume indicators within the water supply network. Over the research period, the volume of water produced and sold was found to decline, even as the number of inhabitants using the network increased. On the other hand, there is a growing demand for water used for own purposes by company, as related directly to their development. Water losses and values determined for the water-loss volume indicator both show a downward trend for the analysed CWSS. It is further observed that, in January, March and May, the loss of water is above average, while the volume of water lost in the other months is below average.
