Determination of Average Water Demand and Diurnal Consumption Pattern for a Multifamily Apartment Complex in Peshawar

Abstract: Accurately estimating and understanding domestic water demand and consumption patterns is essential for the efficient planning and management of drinking water supply systems. Traditional methods for estimating water demand are labor-intensive and often rely on assumptions. To overcome these limitations, this study employed a novel approach using highprecision data loggers to monitor water levels continuously in rooftop tanks at 5-minute intervals within a residential apartment complex in Peshawar, Pakistan. The findings indicate that per capita water consumption varies between 97 and 209 liters per capita per day (lpcd), with an average consumption of 173 lpcd. This methodology offers enhanced accuracy in quantifying water usage, providing a robust alternative to conventional estimation techniques.

Electric energy consumption (EEC) in groundwater-based drinking water supply systems: analysis and comparison of seven Italian case studies

ABSTRACT Drinking water and wastewater services depend on energy: electric energy consumption (EEC) of this sector amounts to 2–3% of global EEC. The attention of the scientific community and of water utilities about this topic is focused on energy optimization of wastewater treatment plants and pumping stages in drinking water supply systems (DWSSs). However, because of increasingly stringent regulations and because of more and more extended water-source pollution, the need for ‘unconventional’ drinking water treatment systems, which are very energy-intensive, will bring treatment to be a key factor in this scenario. Analyzing EEC in seven full-scale DWSSs, we wanted to control EEC in every single stage of the DWSS (withdrawal, drinking water treatment plant (DWTP) and distribution) and to identify opportunities for reducing energy consumption in DWSS, with a special focus on each drinking water treatment process. The most energy-intensive unconventional treatment turns out to be membrane filtration by reverse osmosis (for which specific consumption per cubic meter of pumped water is equal to 0.243 Wh/m3), whereas the most energy-intensive conventional treatment turns out to be air oxidation (specific EEC from 0.012 to 0.087 kWh/m3). The main strategies for energy conservation can be applied both in management and in the design phase.

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.

The importance of institutional capacity in drinking water supply system governance: A policy evaluation from border area

In most developing countries, the equal access to clean and potable water is a major challenge faced by many communities. This research aims to evaluate water supply system governance policies as well as potential springs, constraints and problems related to the water needs of border communities. This research is a descriptive study using a qualitative approach. The qualitative approach looks at policies, institutions, conflicts, and problems faced, as well as looking at data on water sources, socio-economic challenges, culture, and local wisdom. The research location was in Belu Regency, on the Indonesia-Leste Timor border. Research informants were representatives of local government, academics and the community. The problems faced are the underdevelopment of piped networks due to budget constraints, low capacity and quality of human resources, and the absence of specific regulations governing the Drinking Water Supply System (SPAM). The study area has springs spread across 11 subdistricts, with raw water potential ranging from 0.5 to 250 liters per second. Most of these water sources are good for community consumption, but some have not been optimally utilized so that they cannot be fully utilized to meet the needs of the population. The results show that SPAM management policies can be implemented to a certain extent, but have not yet run optimally because they still require capacity building and competence of the apparatus and local communities and an increase in the role of local governments to help implement central government policies in relation to assistance tasks and as a tool for deconcentration of the central government. In conclusion, the potential of raw water sources has not been fully utilized due to the challenges of infrastructure development and the limited capacity of human resources and budgets. Without good management and institutional support, communities will continue to face problems related to access to clean water.

IMPROVEMENT OF OPERATION AND RESEARCH METHODOLOGY OF THE HYDRAULIC FLAKE FORMATION CHAMBER FOR DRINKING WATER SUPPLY

Ukraine’s surface water sources are unsatisfactory due to pollution caused by industrial and agricultural activities and the Russian invasion. As the natural water quality deteriorates, the treatment plant’s efficiency in preparing drinking water for the population’s needs decreases. The hydraulic flake formation chamber allows for physicochemical processes that produce large and solid flakes of metal hydroxides with impurities that quickly settle and are then removed from the water. This study aims to develop a methodology for experimental research on the new design of a swirl-vortex flake formation chamber that intensifies the water purification process in the domestic and drinking water supply systems. The proposed design of the swirl-vortex chamber has dimensions of 0.75×2.0 m and a height of 0.65 m. Due to the installation in the first section of 4 fittings with nozzles, two pieces on each pipe, and in the second section, six fittings with nozzles, three pieces on each pipe with a diameter of 6–10 mm, it is possible to increase the effect of water illumination. The authors performed hydraulic modelling following the Reynolds criterion (Re) and the Froude criterion (Fr). We conducted experiments using artificial turbidity water. White-blue clay was used as a turbidant because it contains more small particles than the white-green one. We decided to model flake formation chambers according to the Froude criterion (Fr). Modelling according to the Reynolds criterion leads to such large velocity gradients that it simply does not make sense to talk about flake formation processes. We carried out the second series of experiments to obtain a qualitative assessment of the swirl-vortex chamber’s work in forming flakes by studying the deposition of flakes at different velocity gradients and angles of inclination of the nozzles. The best effect of lightening the water in the flake formation chamber occurs at a nozzle inclination angle of 45° to the bottom. The best effect of water clarification happens at a velocity gradient of about 60 s-1 and the water residence time in the flake formation chamber of 200–300 s. Keywords: water treatment, intensification, flake formation chamber, drinking water supply.

Community Empowerment Alternatives to Rural Drinking Water Infrastructure Problems: Case Study of Rural SPAM in Krangkeng District, Indramayu Regency

Abstract. The Drinking Water Supply System (SPAM) is a basic community need that must be provided by the government. Water availability is currently a problem in rural areas of Krangkeng District. The condition of the region often experiences drought during the dry season and only 59.27% of people have access to adequate drinking water. Every year the government provides assistance in the form of physical development and water supply via tank trucks. The lack of public awareness in the sustainable implementation of SPAM has resulted in this problem recurring every year. With this phenomenon, community empowerment efforts are needed to create increased community capacity and active community participation in managing the drinking water supply system in Krangkeng District so that it can be sustainable. This research aims to identify community empowerment alternatives described in the aspects of implementing rural SPAM in Krangkeng District using a qualitative descriptive approach. The research results show that there are aspects that are problematic in implementing SPAM in terms of planning for the provision of infrastructure and drinking water services that are not yet structured. Technically, there is limited water infrastructure that can be utilized, there is no management institution, minimal funding allocation related to SPAM, minimal regulatory aspects and there has been no effort to improve from a social perspective related to the sustainability of SPAM. Based on these aspects, the community empowerment alternatives that can be implemented are education and awareness about the importance of drinking water use, community involvement both as management institutions (pokmas) and as users, involvement in collaborative advocacy networks with external parties, and involvement in monitoring and evaluation. It is hoped that this research can help stakeholders in Krangkeng District in efforts to mitigate problems with the implementation of SPAM and the sustainability of water resources in the future.

Modeling and Control of Drinking Water Supply Infrastructures Through Multi-Agent Systems for Sustainability

Traditionally, drinking water supply infrastructures have been designed to store as much water as possible and to do so during the energy cheap hours. This approach is unsustainable today. The use of digital systems capable of modeling the behavior of infrastructures and the creation of intelligent control systems can help to make drinking water supply systems more efficient and effective, while still meeting minimum service requirements. This work proposes the development of a control system, based on multi-agent systems (MAS), capable of generating an intelligent control over a drinking water infrastructure, based on the use of local interests of the agents and with an emergent behavior coherent with the needs. To validate the proposal, a simulator based on the infrastructures of a medium-sized Spanish city of 5000 inhabitants has been built and the control has been simulated using the MAS. The results show how the system can maintain the objectives set, handling unknown situations, and facilitating the development of future physical systems based on a just-in-time paradigm that guarantees sustainability, as it allows the generation of virtualizations of the infrastructures and their behavior, thus being able to study the best option for an infrastructure to resolve a supply situation.

Hygienic efficiency of ultraviolet disinfection of water in centralized drinking and household water supply systems (systematic review)

Introduction. Drinking water supplied to the population must be safe in epidemic terms. However, some viruses and parasites are resistant to the disinfecting effect of traditionally used agents for water treatment. The use of UV irradiation ensures the microbiological safety of water, but there are factors affecting its effectiveness. 
 The purpose of the review was to systematize scientific data on the effectiveness of the use of UV irradiation in relation to drinking water.

According to the results presented in the publication, pathogenic viruses and bacteria, giardia cysts possess of the least resistance to UV irradiation (100% inactivation). 4 log-inactivation was established for Mycobacteia. E. coli and coliphages demonstrate a wide range of indicators of the resistance to ultraviolet radiation due to the diversity of the studied strains. 
 Conclusion. UV disinfection should be used as an additional method in combination with traditional reagents methods of water treatment. It is necessary to study the effect of UV irradiation on helminth eggs and protozoan cysts.

Online water quality monitoring: a case study in the umbulan drinking water supply system, East Java, Indonesia

Conventional systems that monitor the supply system periodically are considered to be very inadequate. This can cause the water supply distributed to the community to be of poor quality. Therefore, this study aims to evaluate water quality periodically by measuring water parameters such as pH, chlorine and turbidity for 30 days using an online system and portable unit. Portable tools used to measure pH, turbidity and residual chlorine are as follows, namely pH meters (Hanna, HI98017), Turbidity Meters (Hanna, HI 98703), Residual Chlorine meters and measurements with an online system using "Supervisory Control and Data Acquisition”. The average parameter value of the results of online daily monitoring for a month for the pH parameter was a minimum 6.92, a maximum of 7.46, a minimum turbidity of 0.08 nephelometric turbidity unit (NTU) and a maximum of 0.94 NTU. While the residual chlorine minimum of 0.29 mg/L and a maximum of 0.58 mg/L. To determine the accuracy of the offline measurements, measurements were also performed with a portable device four times a month. The comparison of the measurement results is very small, which is the difference in pH parameters is between 0.37-0.50, turbidity is between 0.05-0.21 NTU, and residual chlorine is 0.002-0.006 mg/L. Offline measurements using the portable device are consistent with the online daily monitoring. Future research should focus on optimizing sensor technology for enhanced accuracy and reliability, and developing automated data analysis algorithms to streamline evaluation processes.
