Water Provision

The growing demands for affordable and applicable technologies for decentralized safe drinking water provision have instigated technical innovations in the water filtration industry. Adsorptive filtration appears to be the most affordable, resilient, and socially acceptable solution for households and small communities worldwide. However, water filtration devices have not yet been widely implemented due to lack of awareness for the efficiency of such systems using locally available materials. Water filtration has the potential to secure universal access to safe drinking water by 2030. This special issue has elucidated the applicability, benefits, constraints, effectiveness, and limitations of metallic iron as filter material for safe drinking water provision. Tools to make rainwater a primary water source are also presented together with ways to transform existing centralized water management systems into decentralized ones (sectorization). The knowledge is applicable to a wide variety of situations on a global scale.

Point Of Use

The paper assessed access to WASH service in the Jariban district of Somalia. One hundred and sixty-seven households were sampled to administer a questionnaire. Central tendency and logistical regression were used to analyse the data in SPSS 26. The findings show that access to safe drinking water sources is 57.5%. Of the 42.5% of respondents who did not access safe drinking water source, only 10.8% confirmed that they treat drinking water at the point of use. The main reason for household water treatment was the positive mindset (.272) of the household head towards water treatment. The majority (80.2%) of the respondents access approximately 13 litres per person per day. Woman-headed households were more likely to treat water before drinking than male-headed households. Only 26.9% of the respondents accessed basic sanitation. Of the respondents, 55.7% did not share latrines, while 44.3% share resulting in open defecation. WASH access in the study area remains low, resulting in health-related risks, including diarrhoeal disease. The limitation is that the paper only focused on access to WASH facilities in fragile contexts. A cross-sectional analysis of biological, physical and chemical properties of water at the source and point of use is recommended for further research.

Populations in the Langat River Basin, Malaysia, frequently experience water supply disruption due to the shutdown of water treatment plants (WTPs) mainly from the chemical pollution as well as point and non-point sources of pollution. Therefore, this study investigated the aluminium (Al), arsenic (As), cadmium (Cd), chromium (Cr), and lead (Pb) concentrations in the drinking water supply chain at the basin because of its prolonged persistence and toxic characteristics in the aquatic environment. Three replicates of water samples were collected from the river, outlets of WTPs, household tap and filtered water, respectively, in 2015, for analysis by Inductively Coupled Plasma Mass Spectrometry. Higher concentration of these metals was found in household tap water than in the treated water at the WTPs; however, the concentration of these metals at the four stages of the drinking water supply chain conformed to the drinking water quality standard set by the World Health Organization. The Mann-Whitney and Kruskal-Wallis tests also found that metal concentration removal significantly varied among the eight WTPs as well as the five types of household water filtration systems. With regards to the investigated household filtered water, the distilled filtration system was found to be more effective in removing metal concentration because of better management. Therefore, a two-layer water filtration system could be introduced in the Langat River Basin to obtain safe drinking water supply at the household level.

Before And After

Abstract Access to safe drinking water is a challenge for students in primary and secondary schools in Tanzania. Only 32.7% of primary and secondary schools in Tanzania have access to safe drinking water and the point-of-use water treatment is rarely used. The traditional water disinfection method by boiling is often limited in boarding schools due to cost and time constraints. The objectives were to assess the willingness and attitude of boarding school students toward the use of the alternative water treatment method and determine the quality of drinking water before and after the introduction of the new method. Chlorine tablets were used due to their availability, ease of use, cost, and effectiveness. Weekly evaluations on usage, performance, and acceptability of chlorine tablets were assessed on 42 randomly selected students over a 3-week period in parallel with water sampling and testing before and after using chlorine tablets. Before the introduction of chlorine, only 17% of the students were aware of chlorine tablets, and water sources tested positive for fecal coliform. After introducing the new method, there was a significant increase (p<0.05) in the attitude of students toward water treatment (100%), water quality (78%), and water consumption (67%). The work demonstrates the need to provide access to cost-effective household water treatment methods, especially in public schools that lack access to safe water.

Point Of Use

Safe drinking water is scarce in southwest coastal Bangladesh. Harvested rainwater and rain-fed pond water are the main sources of drinking water for people living in this area. Both government and non-government organizations are promoting aquifer storage and recovery (ASR) schemes to provide safe drinking water for this population. This study assessed the bacteriological quality of both source water and abstracted water from five ASR sites. Water sampling and laboratory analysis for indicator bacteria and physico-chemical parameters were conducted once every 2 months, over a period of 1 year. Samples were taken from source ponds, abstraction wells and household storage containers (point of use) for each of the ASR sites. Although the water from abstraction wells showed a 97% and 82% lowering of E. coli and Enterococci counts, respectively, from that of the source ponds, they did not satisfy the WHO drinking water standard. Moreover, the microbial quality of the water deteriorated at the point of use. This indicates the requirement for both in-house treatment and improved hygiene practice for consuming ASR water.
