This paper uses pragmatic findings and lessons learned from three case studies to deduce that community-based rainwater harvesting (CB-RWH) is an innovative solution to develop sustainable drinking water supply systems in developing countries, especially in Africa and Asia. Taking advantage of traditional community-based activities in African and Asian villages, the water supply system can be significantly improved with the introduction and implementation of CB-RWH systems. Furthermore, sustainable, safe water sources in Africa and Asia can be brought to fruition when transparent self-regulatory management systems are supported through comprehensive design and maintenance guidelines and funded from private and public sources. To this end, the potential for CB-RWH to lead toward greater resilience and sustainability was investigated. Based on case studies of three successful demonstration projects in Africa and Asia, this paper identifies 14 innovative solutions resolving technical, economic, and social problems which have been barriers preventing the wide implementation of CB-RWH in developing countries, especially in Africa and Asia. It also recommends strategies to promote CB-RWH in African and Asian villages, which include the following: implementation of more pilot projects at local levels; promotion of and education in rainwater preservation and harvesting at all levels of the education system; and innovation in micro-funding systems in cooperation with corporate social responsibility activities. These strategies will promote the implementation of CB-RWH as a mainstream and high-priority technique for national, regional, and global water strategies.

Abstract Sustainable Development Goal number 6 declares safe drinking water for all as a human right and it can be used as an indicator to measure development. While urban and municipal residents benefit from safe drinking water through centralized water supply systems, water supply for rural areas and estates were decentralized due to large construction costs, according to the demand-driven approach introducing community governance mechanism for water sources and water supply in rural areas. Community-based water societies emerged as a consequence of this situation. In Badulla district of Sri Lanka, 47% of community-based water societies depend upon natural water springs benefitting 46% of households in a particular area. Recently, two natural water springs dried up affecting 191 households and 10 community-based water societies who depend on natural water springs are regulating their water supply hours due to a long and extended drought situation.This affected 1,953 households in Badulla. Further it represents 8.4% of households who depend upon natural water springs. Owing to the present water scarcity, 37 community-based water societies started catchment protection initiatives with the support of government and non-governmental agencies. One community-based water society in this district has collapsed due to lack of water with the drying up of their natural water spring and another is functioning with an alternative water source. Other community-based water societies are functioning to a varying extent because of water level reduction in natural water springs. While the climate is changing, there are development initiatives that, in particular, are affecting natural water springs.

Limited capacity of government on drinking water supply has demanded the implementation of Community Based Water Supply System, one of them in the form of a Drinking Water User Association (Hippam). An important issue in community-based water supply is sustainability, from which institutions play a critical factor in the sustained provision of drinking water. Institutions relate to management, maintenance and financing systems, and contribute to technology selection and decision making. The purpose of this study is to explore the institutional conditions as a determinant factor for the sustainability of community-based water management. The study also aims to develop a framework for sustainable institutional assessment in community-based drinking water supply. In this study Hippam Mandiri Arjowinangun (HMA) in Malang City, East Java Province was chosen as a case study. HMA has been operating since 1994. The sustainability of HMA regarding applying the principles of institutional support for sustainability was very interesting as a case. The research method applied qualitative research by comparing the benchmark of institutional principles of sustainability with institutional principles applied to HMA. The result shows that HMA has applied the principles of institutional support for sustainability. However, some issues should be addressed in the HMA sustainability include the delineation of the water source boundary, specific attributes for the users, and the rules of water utilization. The study has also produced an assessment framework for the sustainability of community-based drinking water supply systems from the institutional perspective.

Rainwater harvesting is a potential option of water supply to the coastal and arsenic affected rural communities in Bangladesh and during the last few years, several projects were undertaken to promote and install various types of rainwater harvesting systems by government organizations and NGOs mainly for drinking and cooking water supply. A study was undertaken to assess the currently practiced rainwater harvesting systems located in the south west coastal and arsenic affected areas in the country. A total of 1,000 rainwater-harvesting systems were investigated using structured questionnaires; among them 14.8% were community based and 85.2% were household rainwater harvesting systems. The results of this assessment are presented in this paper. Availability of the harvested rainwater, operation, storage and maintenance of community based rainwater harvesting and ensuring water quality to meet the drinking water standard are the important issues that must be addressed properly. A protocol for the operation and maintenance according to WHO guideline can be adopted for the safe and sustainable rainwater harvesting in the country.

Summary. Introduction: Drinking water is one of the most important environmental factors sustaining life and determining human health. The goal of the Russian Federal Clean Water Project is to improve drinking water quality through upgrading of water treatment and supply systems using advanced technologies, including those developed by the military-industrial complex. The most informative and reliable sources of information for assessing drinking water quality are the results of systematic laboratory testing obtained within the framework of socio-hygienic monitoring (SGM) and production control carried out by water supply organizations. The objective of our study was to formulate approaches to organizing quality monitoring programs for centralized cold water supply systems. Materials and methods: We reviewed programs and results of drinking water quality laboratory tests performed by Rospotrebnadzor bodies and institutions within the framework of SGM in 2017–2018. Results: We established that drinking water quality monitoring in the constituent entities of the Russian Federation differs significantly in the number of monitoring points (566 in the Krasnoyarsk Krai vs 10 in Sevastopol) and measured indicators, especially sanitary and chemical ones (53 inorganic and organic substances in the Kemerovo Region vs one indicator in the Amur Region). Discussion: For a more complete and objective assessment of drinking water quality in centralized cold water supply systems, monitoring points should be organized at all stages of water supply with account for the coverage of the maximum number of people supplied with water from a particular network. Thus, the number of points in the distribution network should depend, inter alia, on the size of population served. In urban settlements with up to 10,000 inhabitants, for example, at least 4 points should be organized while in the cities with more than 3,000,000 inhabitants at least 80 points are necessary. We developed minimum mandatory lists of indicators and approaches to selecting priority indices to be monitored at all stages of drinking water supply.

Quality Guidelines

Water quality can affect human health in various ways: through breeding of vectors, presence of pathogenic protozoa, helminths, bacteria and viruses, or through inorganic and organic chemicals. While traditional concern has been with pathogens and gastro-intestinal diseases, chemical pollutants in drinking-water supplies have in many instances reached proportions which affect human health, especially in cases of chronic exposure. Treatment of drinking-water, often grossly inadequate in developing countries, is the last barrier of health protection, but control at source is more effective for pollution control. Several WHO programmes of the International Drinking-Water Supply and Sanitation Decade have stimulated awareness of the importance of water quality in public water supplies. Three main streams have been followed during the eighties: guidelines for drinking-water quality, guidelines for wastewater reuse and the monitoring of freshwater quality. Following massive investments in the community water supply sector to provide people with adequate quantities of drinking-water, it becomes more and more important to also guarantee minimum quality standards. This has been recognized by many water and health authorities in developing countries and, as a result, WHO cooperates with many of them in establishing water quality laboratories and pollution control programmes.
