Local and Low-Cost Filter Media of Simple Water Filtration

Commonly the Installation of a Drinking Water Supply System (SPAM) in Indonesia consists of Coagulation-Flocculation, Sedimentation, Filtration and Disinfection Processes as a complete Process Unit for surface feed water such as rivers or lakes. Similarly, the clean water treatment process in Banjarbaru, South Kalimantan, Indonesia uses intake water sources from irrigation. The intake water from irrigation used by the local Regional Drinking Water Company has good quality with a low turbidity value below the quality standards set by the central government. Based on these qualities, the right process unit to treat the water is by filtration only. Therefore, it is necessary to conduct evaluation and research to improve the efficiency of the process unit and the economic value of the water treatment. The purpose of this study is to investigate and evaluate irrigation feed water treatment by filtration using local and low-cost filter media. The filter reactor is designed with a rapid media filter type. The media is characterized using energy dispersive X-ray spectroscopy (EDS) and a scanning electron microscope (SEM) which is plugged in with EDS to find out the primary constituents and morphological information and after knowing the characterization of the media, and followed by tested the media placed in the water filter reactor with data collection. The results show that the size of the filter media has great effect on the quality of the processing water, which the smaller the media diameter conducted high selectivity and speed up filtration time. The greatest result obtained from testing feed water with media is 87.64%. Turbidity of the feed water sample process, which was previously 0.34 NTU, could be decreased to 0.02 NTU. Effective size of 0.4 mm and uniformity coefficient of 1.35 mm are the optimal allowable values.

Could California's groundwater resource management lessons be beneficial to England?

In California, Groundwater Sustainability Agencies (GSAs) are basin/catchment-specific water organizations mandated by the Sustainable Groundwater Management Act of 2014 to manage groundwater sustainably by 2040/2042. A GSA can charge replenishment fees for pumped groundwater and these fees can be used to: (a) monitor basin hydrologic conditions; (b) improve the water budget accuracy; (c) increase water availability through management actions and projects; (d) mitigate undesirable results; and/or (e) pay for activities including issuing allocations and limiting production to allocations. In England, housing is frequently proposed in river basin catchments that face water resource challenges. High profile examples are the Arun Valley and Cambridge. The current National Planning Policy Framework manages water resource planning strategically through water company Water Resource Management Plans or Environment Agency River Basin Management Plans. These processes can be slow to respond to development requirements. England might look to California's practices that require water users and developers to pay for ‘water credits’ or fees. This could involve a ‘Watermaster’ charged with local or catchment scale resource management and project implementation. This Watermaster could engage all stakeholders including the local water company, farmers, the Environment Agency and the local authority, none of whom is well positioned to act in isolation.

Implication of Urban Domestic Water Distribution on Human Health in Machakos Central Ward, Machakos County

The world's water resources are running out, and this situation is made worse by how quickly people are populating new areas, particularly in developing nations. This has highlighted the critical requirement for prepared action to manage water resources for sustainable development efficiently. Increasing water demands due to climate change, global pressures from urbanization, the already-existing unsustainable variables, and challenges of water supply systems in urban centres pose a challenge in managing water resource effectively. The purpose of the study was to investigate the implication of urban domestic water supply on human health in Machakos Central Ward, Machakos County. Using a Survey Research Design (SRD) both primary and secondary data was collected by use of questionnaires, face-to-face interviews, photography, use of GIS, authors’ observation, and the review of relevant literature in order to (1) document household water supply, (2) determine water quality for the identified categories of households and domestic water supply systems, and (3) Determine how the distribution and coverage of domestic water in a household or home affects the prevalence of water-borne illnesses. The target population was 8,331 households, from which a sample size of 381 respondents was selected. These included households, water vendors and key informants from the Machakos Water and Sewerage Company. Questionnaires (for households and vendors), interview schedules (for water officers and chiefs) and observation schedules were used as instruments for data collection. Data was analysed using Microsoft Excel and Statistical Package for Social Sciences (SPSS) software. The results revealed that the major factors attributed to lower accessibility are shortage of water, high cost of piped water connection, poor coordination, and participation of stakeholders, repairing of old and broken pipes. As a result, nearly half of the dwellers prefer to use alternative sources, exposing them to the risks of water-born diseases

Installation of Clean Water Piping for Resident on Jl. Arjuna, RW 08 and 09, East Labuh Baru, Pekanbaru

Water is a crucial resource for sustaining life; however, access to it through the Regional Drinking Water Company (Indonesian: Perusahaan Daerah Air Minum [PDAM]) remains limited in certain communities. As a result, residents frequently depend on groundwater sourced through independent pumping by households, places of worship, public facilities, private and government offices, and others. An assessment of the buildings on Jl. Arjuna RW 08 and 09, East Labuh Baru District, Pekanbaru, indicates a significant lack of adequate clean water installation systems, highlighting a need for targeted community service efforts. This initiative aims to rectify these deficiencies by drilling wells to establish reliable sources of clean water and installing a comprehensive clean water piping system to ensure effective distribution from the source to the end users, thus aligning with Indonesian National Standards (SNI). The project involves faculty members as part of their commitment to the tri-dharma of higher education, offering both a practical learning opportunity for students and a valuable service to the community.

The Effect of Service Recovery and Situational Factors on Consumer Forgiveness

The purpose of this study is to (1) determine the effect of service recovery on consumer forgiveness, (2) determine the effect of situational factors on consumer forgiveness. The respondents of this research were 100 consumers of the Tirta Dharma Regional Drinking Water Company, Bengkulu City. The collected data was analyzed using multiple linear regression analysis. The results showed that service recovery has a positive effect on consumer forgiveness. That is, the better service recovery, the higher consumer forgiveness will be. Situational factors have a positive effect on consumer forgiveness. That is, the higher the situational factor of consumers the higher the consumer forgiveness. Implementing service recovery management is considered to have a significant impact on customer evaluation because customers tend to be more emotional when involved in service restoration than during the interactional time of service. When this is done well, a dissatisfied customer can become one of the most loyal customers who acts as public relations for the organization through word of mouth. Improve service quality so that the possibility of service failure can be avoided. With good service quality there will be a positive social environment talk of company services.

Politicizing and economizing – domestic water charges in Ireland – from a free public service, to pay-by-volume, and back again

PurposeThis paper aims to explore why a country with significant under-investment in water infrastructure has not successfully imposed domestic water charges. Drawing on an economization lens, it examines how an economy emerged in the imposition of water charges but was subsequently hidden due to their politically motivated suspension.Design/methodology/approachDrawing on documentary evidence, a theoretically informed examination of the “economization” process is set out. This examination recognizes the central role sustainability plays in water management but illustrates how sustainability must be integrated with environmental, social, economic, cultural and political factors.FindingsThe findings set out the challenges experienced by a state-owned water company as they attempt to manage domestic water charges. The paper reveals that while the suspension of water charges has hidden the “economy” within government subvention, the economic and sustainable imperative to invest in and pay for water remains, but is enveloped within a political “hot potato” bringing about a quasi-political/quasi-economic landscape.Practical implicationsThe findings demonstrate how the effective and sustainable management of domestic water supply requires collaboration between multiple participants, including the government, the European Union, private citizens and the water protest movement.Social implicationsWhile highlighting the challenges faced by a country that has seriously under-invested in its water resources, the paper reflects the societal consequences of charging individuals for water, raising important questions about what water actually is – a right, a product or a political object.Originality/valueShowing how an economy around domestic water supply in Ireland was revealed, but subsequently hidden in “the political”, the paper illustrates how sustainability is as much about economics and politics as it is about ecological balance and natural resources.

Using continuous online monitoring measurements to determine the Serayu River’s water quality status

Abstract The Serayu River is a national strategic river that provides essential water to local water companies, industrial operations, agriculture, and household irrigation in the surrounding community. The Serayu River’s condition is currently deteriorating due to erosion and pollution. The primary goal of this investigation is to quantify the Serayu River’s water pollution. Data from continuous online monitoring stations at Wanganaji Dam (upstream) and Gerak Serayu Dam (downstream) will be used to assess temperature, DO, pH, TDS, DHL), turbidity, and ammonia levels. The research methodology for this study included descriptive statistical analysis and the STORET method, which is based on the regulatory framework established in the Republic of Indonesia by Ministerial Decree Number 115 of 2003 and Government Regulation Number 22 of 2021. The results show that the water quality upstream of the Serayu River (Wanganaji Dam Station) partially meets most of the measured parameters while still meeting the required quality standards. Meanwhile, the water quality in the downstream part of the Serayu River (Gerak Serayu Dam Station) has DO values (3.68-4.98 mg/L), turbidity (36.78-95.48 mg/L) that exceed the required quality standards. The water quality at the Serayu River’s two dams ranges from moderate to heavily polluted.

Determining the effect of environmental factors, work postures and mental workload on musculoskeletal disorders in rescue workers and accidents of one of the water and sewage companies in Iran.

Musculoskeletal disorders are one of the most important problems faced by ergonomists today. This study was conducted with the aim of investigating the effect of weather conditions, working conditions and mental workload on musculoskeletal disorders of rescuers and water and sewage company accidents in hot and cold seasons. The present study was a longitudinal study that was performed on all employees of rescue and disaster teams of Shiraz Water and Sewerage Company in Iran (184 people) by census. Demographic and Nordic questionnaires, NASA Load Index (NASA-TLX), work environment assessment with temperature screening checklist and workplace ergonomic risk factor (WERA) assessment method were performed by the researcher. The collected data were analyzed using SPSS version 23 software and parametric and non-parametric statistical tests. The results showed that the highest and lowest prevalence of musculoskeletal disorders related to knee and back in winter and thigh in summer with prevalence of 57.1, 55.4 and 6%. The comparison of exposure to heat stress factors in summer and winter seasons showed that the temperature factors and work clothes of the workers in both seasons are in worse conditions than other factors (P < 0968). The results of the mental workload of people in two seasons showed that the highest and lowest mental workload is related to physical changes in the winter season and frustration in the summer season, and this relationship was significant (P < 0.001). Using multiple logistic regression model, the potential risk factors for musculoskeletal injuries including age, height, BMI, level of education and work experience in both hot and cold seasons were compared. The results showed that in summer, work experience (OR = 1.16 (1.06-1.28.)) and height (OR = 1.03(0.98-1.08) had a direct effect on the prevalence of pain and discomfort arranged in the back areas. One year of increase in work experience significantly increases the chance of a disorder in the back by 16% and a one centimeter increase in height increases the chance of a disorder in the lumbar region by 3%, although this relationship is significant. It is recommended that suitable solutions such as using appropriate and up-to-date mechanical tools, reducing activity time, increasing rest time, increasing the number of personnel in order to reduce mental workload, using work clothes suitable for the season and type of work, and ergonomics training for workers are on the agenda of company officials. Water and sewage should be placed.

Households’ access and expenditure on water services: Examining intra-urban differences in the Accra metropolis, Ghana

Despite years of investment into the water sector in Ghana, access to and expenditure on potable water for drinking and domestic use remain a challenge for most urban households. However, within the urban context, the severity of water challenges varies from one residential community to another, with less research attention often given to such intra-urban differences. To address this gap, this study examines differences in household access and expenditure on pipe-borne water in three varying socio-economic residential communities in Accra. The study used a convergent mixed method design and drew on secondary literature, to examine the differences in households' access to and expenditure on water. The findings revealed that Jamestown, a low-income residential community, had the lowest connection to the Ghana Water Company Limited (GWCL) grid, with many respondents depending on pipe-borne water outside dwellings operated by private water retailers. While the findings showed no significant differences in the regularity of flow and expenditure on water among the three varying socio-economic communities, the paper argues that low-income communities such as Jamestown are likely to be more affected due to existing socio-economic deprivation and vulnerability contexts. Based on the study findings, we recommend that efforts be made to increase investment in water infrastructure to enable households to connect to the GWCL grid. Attention should also be given to low-income households, who often lack the means to pay for services that will enable them to connect to the GWCL grid. Further, we recommend improved collaboration between local communities and GWCL as a way of fostering strategies that address the peculiar water challenges in local communities.
