Clean water distribution machines are very important for local drinking water companies to be able to supply clean water to customers. The need for water continues to increase, so an analysis is needed to determine the decline in engine pump performance in the production process. Maintenance activities need to be carried out to maintain the reliability (realiability) of the machine so that it can operate properly. Therefore, a good strategy is needed to maintain the continuity of the production process. The purpose of this research is to measure the performance of the water distribution pump machine / equipment associated with the low level of clean water production, to identify the losses experienced by the company. The Overall Equipment Effectiveness (OEE) value obtained before repairs were carried out in November 2019 for Lapi I was 69.38% and Lapi II was 69. 75% while in December 2019 for Lapi I it was 74.02% and Lapi II was 73.65% still below the JIPM standard, namely ≥85%. From the results of the six big losses, the clean water distribution pump machine as a whole still needs evaluation to make improvements in increasing effectiveness and productivity, especially in the problem of redeuced speed losses so that suggestions can be made to improve the clean water distribution machine. After repairs in January 2020 for Lapi I was 87.90% and Lapi II was 87.26% while in February 2020 for Lapi I it was 90.34% and Lapi II was 85.81%.

Drinking Water Production

Free-living amoebae have been detected in a large number of man-made water systems, including drinking water distribution systems. Some of these amoebae can host amoebae-resisting bacteria, and thus act potentially as reservoirs and vehicles for a number of pathogens. The objectives of this study were to characterize the amoebae and amoebae-resisting bacteria present in different raw waters used for drinking water production, and to assess the efficiency of different treatments applied for drinking water production in removing or inactivating these amoebae. The preliminary results of this study confirm the presence of amoebae and amoebae-resisting bacteria in raw waters used for drinking water production. Due to their capacity to encyst, most of these amoebae are extremely resistant to disinfection processes. In these conditions, preventing the dissemination of these micro-organisms through drinking water will mainly require their physical removal by clarification and filtration processes. The particular hazard that amoebae-resisting bacteria represent in drinking water production should be taken into account in any risk assessment conducted in the framework of a water safety plan, and control strategies based on physical removal rather than disinfection should be adopted where necessary.

About forty per cent of drinking water in The Netherlands is produced from surface water. Dutch water companies, that have to rely on this source, are dealing with major water quality problems due to the use of herbicides on pavements. Voluntary measures and bans have had only limited effect on the reduction of emissions of herbicides that runoff from pavements into surface water in The Netherlands. The effects on the production of drinking water from surface water should play a role in the authorisation of pesticides. Stricter regulations, including mandatory emission reduction measures and certification, are necessary. The enforcement of existing Dutch surface water pollution laws should solve part of the problem. Due to the international nature of most of the surface water used for drinking water supply, it is necessary that other countries take measures as well. European legislation brings a solution closer if implemented well and seriously enforced. The threat of strict legislation keeps pressure on the transition towards decreasing the dependence on chemicals for weed control on pavements.

Clean water is a primary need for humans in every country. The availability of clean water must be guaranteed in time, quantity and quality. The need for water for both domestic and non-domestic needs continues to increase from year to year. To meet the needs of clean water, the people of Karo Regency need clean water sources that are suitable for drinking. Water resources are water discharge and population for water distribution. In finding the amount of water demand, an analysis of the population and analysis of clean water production is carried out. Determining the need for clean water and the population in Karo Regency uses the Geometry method which this method shows the largest population growth so that it can be planned for clean water needs until 2027. Based on the results of the projected population plus the number of water needs in 2027 as many as 491,444 people, the required water discharge is 907,799 l/s while the current production capacity is 14,744.831 l/s, so the additional capacity needed is 0.01003 m3/s. Implementation in the construction of clean water facilities must be adjusted to the level of social, cultural, and economic conditions of the community.

Efficiency And Effectiveness

This paper aims at identifying strategies to improve the performance of Ethiopian local governments in supplying drinking water. Therefore, a case study of Ambo (Ethiopia) is performed, on basis of document analysis, interview and focus group discussion. This allows operationalizing Pollitt and Bouckaert’s (2011) production process model, by defining input, activity, output and outcome indicators relevant for drinking water supply in the context of developing countries. The indicators and their interrelations subsequently allow coining efficiency-improvement and effectiveness-improvement strategies. The paper finds that most performance improvement strategies do not involve a trade-off between efficiency and effectiveness: investing in the maintenance of the water distribution network, involving the community in the production process, ensuring a minimum quality threshold, improving procurement policies, and relying on ground water contribute to both and deserve being implemented. On other aspects, related to commercial policies and the quality of water, local policymakers need to make a choice between pursing efficiency and effectiveness. The paper contributes to the ongoing discussion on the added-value of governance for the 2030 Agenda, and paves the way for benchmarking Ethiopian local governments, and warrants further research onto the added value of participation for development.

Number Of Customers

Water is one of the primary needs for humans so that everyone has the right to get clean water for their daily needs. Along with increasing population, the need for water will increase. So with that the PDAM must sell clean / decent water to its customers, clean water becomes the focus of attention and has the greatest power compared to other problems. Because water is a basic necessity, most of the companies impose rates that can be reached by the community and prices are adjusted to the growth in demand. The purpose of this research is to get a grouping of the number of customers of clean water companies in all provinces using the K-Means Algorithm, K-Means is a method for grouping data into a cluster by calculating the closest distance from a data to a centroid point. Clusters used are high level clusters (C1), medium level clusters (C2), and for low level clusters (C3). Centroid data obtained is for high-level clusters (C1) which are as many as 7710154, for medium-level clusters as much as 929586, and for low-level clusters as much as 112462. Based on the calculated data obtained high-level results, namely the province of Indonesia, for the medium level namely province North Sumatra, DKI Jakarta, West Java, Central Java and East Java, and other provinces are low levels. So that this result can be a support for the company in order to increase water needs.
