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.

Background: Education is one of the most important drivers for helping people in developing countries lift themselves out of poverty. However, even when schooling is available absenteeism rates can be high. Recently, focus is being given on whether or not WASH interventions can help reduce absenteeism in developing countries. However, none has focused exclusively on the role of drinking water provision. We report a study on the association between absenteeism and provision of treated water in containers maintained in schools. Methods and Findings: We undertook a quasi-experimental longitudinal study of absenteeism rates in 8 schools, 4 of which received one 20 l container of treated drinking water per day. The water had been treated by filtration and ultraviolet disinfection. Weekly absenteeism rates were compared across all schools using the negative binomial model in generalized estimating equations. There was a strong association between the provision of free water and reduced absenteeism (Incidence rate ratio = 0.39 (95% confidence intervals 0.27-0.56)). However, there was also a strong association with season (wet versus dry) and a significant interaction between receiving free water and season. In one of the intervention schools, it was discovered that the water supplier was not fulfilling his contract and was not delivering sufficient water each week. In this school, we showed a significant association between the number of water containers delivered each week and absenteeism (IRR = 0.98 95% CI 0.96-1.00). Conclusion: There appears to be a strong association between providing free and safe drinking water and reduced absenteeism, although only in the dry season. The mechanism for this association is not clear but may be in part due to improved hydration leading to improved school experience for the children.

Treated Drinking Water

This communication is motivated by recent publications discussing the affordability of appropriate decentralized solutions for safe drinking water provision in low-income communities. There is a huge contrast between the costs of presented technologies, which vary by a factor of up to 12. For example, for the production of 2000 L/d of treated drinking water, the costs vary between about 1500 and 12,000 Euro. A closer look at the technologies reveals that expensive technologies use imported manufactured components or devices that cannot yet be locally produced. In the battle to achieve the United Nations Sustainable Development Goal for safe drinking water (SDG 6.1), such technologies should be, at best, considered as bridging solutions. For a sustainable self-reliance in safe drinking water supply, do-it-yourself (DIY) systems should be popularized. These DIY technologies include biochar and metallic iron (Fe0) based systems. These relevant technologies should then be further improved through internal processes.
