Mthente Research and Consulting Services was appointed by the Energy and Water Sector Education and Training Authority (EWSETA) to conduct a post-implementation review of the War on Leaks (WoL) project. Launched in 2015 as a presidential initiative in response to South Africa’s pressing water conservation challenges, the WoL project aimed to address the inefficient use of water and reduce losses caused by physical leakages and commercial inefficiencies. The review provided EWSETA with critical insights into how well the project performed against its original objectives and offered valuable lessons to inform the planning and execution of future initiatives of a similar scale.
To conduct the review, Mthente adopted a mixed methods approach grounded in the OECD/DAC evaluation criteria—relevance, effectiveness, efficiency, impact, and sustainability. The study included a comprehensive document review, a quantitative survey with 200 project beneficiaries, and qualitative interviews with key stakeholders, including representatives from the implementing agent (Rand Water), project managers, and training providers.
The triangulation of data from multiple sources enabled Mthente to assess the successes and challenges experienced during implementation, as well as the broader impact and sustainability of the project. The findings offer EWSETA a well-rounded understanding of the WoL project’s achievements and limitations, serving as a foundation for improved project design, implementation, and evaluation in the future.
