“…This study defines accountability as a process of mutual responsibility between at least two persons or organisations that involve asking for and giving accounts of conduct (Roberts and Scapens, 1985). Over the years, public authorities around the world have made considerable efforts to improve access to potable water for rural and urban populations by using new technologies (Chen et al, 2020;Post et al, 2019) and various forms of new public management and new public governance (Burke and Demirag, 2017;Kirkpatrick et al, 2006;Koppenjan and Koliba, 2013). In developed countries, for instance, public authorities often use public sector-owned corporations to fulfil this need (Peda and Vinnari, 2019;Vinnari and N€ asi, 2008).…”

PurposeThis study analyses how the implementation of PPPs to operate rural water infrastructures and deliver water to local population has led to a new accountability archetype.Design/methodology/approachThe archetype theory is used to analyse the process of implementing PPPs as a new archetype and setting up systems and structures of accountability between contracting parties. The empirical part of the study is based on extensive document analysis in an East African country. Documents analysed are from governmental sources, UNICEF and the World Bank and cover a period from 1998 to early 2019.FindingsThe process of implementing PPPs was revolutionary at the national level and evolutionary at micro levels. The sequence of the change process moved from central to peripheral. The linearity followed a reorientation track strategy. Setting up systems and structure of accountability was evolutionary, peripheral to central following the reorientation strategy. National authorities reacted proactively to comments and suggestions from international donors and local population. However, not all districts have fully implemented PPPs in their rural water sector. The structure of accountability at the local level, however, still suffers from logistical and professional capacity constraints.Research limitations/implicationsEmpirical findings cannot be generalised to other situations, but the theoretical framework used in this study can be applied elsewhere.Practical implicationsGiving priority to hearing from end users themselves before designing and implementing policies that intend to respond to specific local needs is recommended.Originality/valueThis study explains the ways in which micro-organisational change can lead to revolutionary archetypes such as PPPs, whereas the implementation of systems and the structure of accountability at inter-organisational level remain evolutionary.

“…Newly emerged technology that is Ultraviolet light-emitting diodes (UV-LEDs) is poorly characterized in full-scale drinking water treatment systems and hence Peter Jarvis et al,2019 investigated UV-LED reactor that is world's first full-scale UV-LED reactor for cleansing of pathogenic microbes from drinking water (54). While Electrolysis process performed well than chlorination in decreasing bacteria and opportunistic pathogens along with regulation on the formation of by-products (56). Consequently, to overcome tackles of chlorination additional literature is assessed and it appears that the new technology Electrochlorination that can be used to treat the drinking water: Eugene & Suffet, 2002, present a new technology that reduces the shortcomings of the chlorination process.…”

The Sustainable Development Goal 2015-30, which is the blueprint to achieve a better and sustainable future for all includes goal number six, aiming at the provision of clean water and sanitation by 2030 worldwide. But still the rural areas in developing nations are predominantly facing the scarcity of pathogen-free drinking water, which creates an urgent need for research in the area of water disinfection. The paper presents a systematic literature review of the conventional and novel water disinfection techniques supported by a bibliometric analysis based on the data from Scopus and Web of Science data from the year 1980 to 2020 for all the disinfection techniques. The novel and latest water disinfection technology in the literature studied by few researchers are also discussed and it can be concluded that the research related to these latest technologies is fewer and real-life usage is very scanty. The detailed literature review indicates the need for novel, decentralized, low-cost water disinfection technology for providing clean and pathogen-free water to all, overcoming the problems related to access of safe drinking water to rural communities. The paper also identifies the research gaps related to new technologies for water disinfection which needs to addressed in further studies.

the paper deals with the variant of partial diversification of water supply facilities where the surplus of electrolytically generated hydrogen produced by electrolysis of sodium hypochlorite - water disinfectant -can be used for heating of production facilities and nearby consumers, production of conditioned water for technological needs from atmospheric precipitations, which confirms the possibility of economically expedient participation of the water supply enterprise in forming the regional market.
