Success Factors for Water Safety Plan Implementation in Small Drinking Water Supplies in Low- and Middle-Income Countries

Water Safety Plan (WSP) implementation has the potential to greatly improve, commonly very challenging and resource limited, small drinking water supplies. Although slower than in urban or high-income settings, the uptake of WSPs in low- and middle-income countries (LMICs) is accelerating. Understanding the factors which will make a WSP successful will further improve efficient uptake and assist with its long-term sustainability. Based on an extensive literature search using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISM-A) methodology, 48 publications, including case studies and guidance documentation, formed the basis of this review. These were analysed using inductive and deductive coding methods to (i) identify the success factors applicable to WSP implementation in small drinking water supplies in LMICs and (ii) to investigate which factors are more or less critical depending on the geography and level of development of the implementing country. Key challenges identified during the review process were also noted. A comparison of these success factors was made with those identified from high-income and urban settings. The three most important success factors identified are the development of technical capacity, community engagement, and monitoring and verification. Factors specific to small drinking water supplies in LMICs include support from non-government organisations, integration into existing water sanitation and hygiene (WASH) programs, simplicity, and community engagement. Certain factors, such as adaptability, the use of guidance documentation, international collaboration, the role of pilot studies, knowledge sharing, and stakeholder involvement are applicable to all WSP settings. Due to the specific challenges faced by small drinking water systems and the limited number of original research publications on this topic, this study highlights the need for further data collection and research focused on success factors in these settings. It is anticipated that the consideration of the success factors identified in this study will assist implementers in improving the uptake and long-term sustainability of WSPs in small drinking water supplies in low- and middle-income settings

Experiences from integrating water and sanitation safety planning in small systems in rural Serbia

The WHO recommends a risk management approach to ensure safe drinking-water and sanitation, so-called Water Safety Planning and Sanitation Safety Planning. However, applying these risk management approaches separately in small-scale drinking-water supply and sanitation systems might be challenging for rural communities with limited human, financial, and administrative resources. An integrated approach seems a better option. In this study, an integrated water and sanitation safety planning (iWSSP) approach was developed together with guidance and training material for the practical application of this novel approach. The integrated approach was piloted in three small systems in rural Serbia to identify benefits and suggestions for improvement which can be used for potential future scaling-up. Implementing iWSSP at the pilot sites contributed to a better understanding of both drinking-water supply and sanitation systems. It also resulted in increased awareness, knowledge, and understanding among staff of drinking-water supply and sanitation services. Key experts, including external facilitators, played a crucial role in the implementation of iWSSP. Future scaling-up of the integrated approach could be enabled if more guidance, easy-to-use training materials and templates become available which can be adapted and updated as needed. HIGHLIGHTS We developed and tested integrated drinking-water safety planning and sanitation safety planning (iWSSP).; iWSSP helps small rural systems to better understand how both systems influence each other which supports identifying hazardous events.
