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.

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.

Inadequate access to safe drinking water is one of the most pervasive problems currently afflicting the developing world. Scientists and engineers are called to present affordable but efficient solutions, particularly applicable to small communities. Filtration systems based on metallic iron (Fe0) are discussed in the literature as one such viable solution, whether as a stand-alone system or as a complement to slow sand filters (SSFs). Fe0 filters can also be improved by incorporating biochar to form Fe0-biochar filtration systems with potentially higher contaminant removal efficiencies than those based on Fe0 or biochar alone. These three low-cost and chemical-free systems (Fe0, biochar, SSFs) have the potential to provide universal access to safe drinking water. However, a well-structured systematic research is needed to design robust and efficient water treatment systems based on these affordable filter materials. This communication highlights the technology being developed to use Fe0-based systems for decentralized safe drinking water provision. Future research directions for the design of the next generation Fe0-based systems are highlighted. It is shown that Fe0 enhances the efficiency of SSFs, while biochar has the potential to alleviate the loss of porosity and uncertainties arising from the non-linear kinetics of iron corrosion. Fe0-based systems are an affordable and applicable technology for small communities in low-income countries, which could contribute to attaining self-reliance in clean water supply and universal public health.

There is a serious problem of rural unsafe drinking water in china,but only it is essential for legislation to solve comprehensively.Through the analysis of the legislative background, legislative basis and legislative framework system of rural safe drinking water,the paper explores some legislative issues.Water source contaminated by industrial pollutants, agricultural pollutants, domestic pollutants, is the biggest obstacle to rural drinking water safety.Rural safe drinking water legislation have sufficiently the constitutional basis and the basic law basis. Legislative framework system is composed of drinking water source protection,rural water supply planning,project financing,operation and management mechanisms,emergency warning system, pricing system, supervision system etc. Rural safe drinking water legislation will play a significant role in solving fundamentally the problem of rural safe drinking water.

Drinking water is a basic need for humans. The provision of drinking water throughout Indonesia is an obligation that has been stated in UUD 45. Based on the Bappenas study with the Ministry of Public Works, universal access to drinking water is targeted to reach 84,8% nationally. Then, this universal access must increase to 92,2% in 2018. In the end, access to drinking water for the community in 2019 is 100%. Based on this description, every region in Indonesia must have universal access to proper drinking water. Manggarai Regency is one of the districts that will alleviate the problem of universal access to drinking water. Existing water sources in Manggarai Regency are in various locations of hills and mountains. This water source is a source of water that can be used as a source of drinking water. Based on the study of SPAM Master Plan, residents of Manggarai Regency who have had access to adequate drinking water are 57.61%. The percentage value is still below the threshold of decent MDGs in 2015 which is 68%. Considering that the target of fulfilling universal access to drinking water in 2019 is 100%, it is necessary to have a major breakthrough in drinking water supply in Manggarai Regency. One way that needs to be done is to evaluate the drinking water needs. Based on the results of a field survey, Manggarai District has the potential of drinking water sources of 150 Lps, water has been utilized by 30 Lps and the services to be developed are 40 Lps. The method used in this research is quantitative descriptive method. The results of the analysis obtained from the study on the evaluation of drinking water needs are long-term drinking water needs in 8 (eight villages), the capacity of clean water from Wae Decer water spring cannot supply drinking water by 2029. In 2028, the remaining clean water capacity from MA. Wae Decer only has 0.16 liters per second. If Wae Decer SPAM wants to be extended to 2037 according to long-term planning, then in 2018 the required supply capacity is 48,15 liters per second. The difference of 8,15 liters per second can be taken from Wae Decer which still has the remaining idle capacity of 77 liters per second in 2037. This capacity can be used for the development of drinking water reaching other villages that intersect with the DED Wae Decer system and or added from source of springs adjacent to Wae Decer clean water network.
