Sustainable Water Resource and Environmental Management in Developing CountriesOLUGBOYE, DAYO. (2017)Water supply service delivery has been recognised as a complex challenge facing communities in developing countries. Its particularly serious in sub-Saharan Africa where a significant proportion of the population still lack basic access to safe drinking water supply. Over the years, many externally supported community-managed water facilities have failed to deliver sustainably. This results not only in a loss of financial investment but also constitutes a real threat to people’s health and well-being. Therefore, this study aimed to explore options for innovative water service delivery approach that can support vibrant water supply provision as well as provide a guidance framework for sustainable water service delivery in Nigeria. Due to the socio-technical complexity of the research, the mixed method approach was found to be the most suitable research method after extensive considerations and reviews of other several available research methodologies. The study found that the hand-dug wells (HDW) have enormous potential in sustainable water service delivery to households within the proposed framework arrangement. This research successfully presented a unique model, based on the concept of HDW self-supply, using rope pump technology in conjunction with a community-based water resource management concept. The proposed approach led to the production of a set of Guidance Frameworks that will aid planning and implementation of a proposed solution. This was validated with key stakeholders and it applicability was rated highly relevant in the water sector. The approach did not only address the question of technical and financial sustainability but also make a case for environmental sustainability. Hence, ensuring that meeting present domestic water needs will not jeopardise the ability of future generations to meet their own needs. Further research was recommended to ensure wider applicability of the model.
