Project Effectiveness Review: Expanding Water and Sanitation in Urban Freetown, Sierra Leone



Oxfam in Sierra Leone works through a development-oriented approach. We aim to enable people to make the most of every opportunity. The thrust of our programme has been on public health, women’s political empowerment, education, economic and social justice and governance. We seek to improve public health   through better access to sustainable, safe and sufficient water, sanitation and hygiene (WASH) services. We also support the development of appropriate pro-poor water and sanitation policies and have model decentralised implementation through good practice in Kailahun, Koinadugu and Freetown. 

The Freetown WASH Consortium (FWC) is a partnership of four international NGOs: Action Against Hunger, Concern Worldwide, Save the Children and Oxfam (lead agency), which since 2009 has been working to address chronic and acute WASH issues in the poorest communities of Western Area Urban (WAU) and Western Area Rural (WAR). The consortium programme – predominantly funded by the UK Government’s Department for International Development (DFID) – was implemented in three phases, from 2010 to 2019. This Project Effectiveness Review will evaluate Phase III of this programme, which was implemented from October 2016 to March 2019, in the geographical areas where Oxfam was the implementation lead. 

As part of Oxfam GB’s Global Performance Framework, a Project Effectiveness Review rigorously assesses the impact of a project for the people it intends to support. Specifically, impact is evaluated against Oxfam GB’s global indicator forSustainable Water and Sanitation. Quantitative and qualitative data will be collected via household surveys and interviews with community leaders, both in areas where the project operated (intervention group) and in comparable areas where no project or similar activities were conducted (control group). 

Oxfam is recruiting a consultant to manage field work for this Project Effectiveness Review, which is expected to take place in WAU. Oxfam’s Impact Evaluation Adviser will be responsible for the overall methodology, but will work in close collaboration with the consultant as well as the Oxfam team and partner organisations. The role of the consultant is to (1) assist with finalising the evaluation design, sampling strategy and data collection tools, (2) recruit, train, supervise and mentor a team of enumerators to carry out data collection activities (3) ensure that data collection meets Oxfam’s high quality standards, prioritises privacy and complies with data protection laws (e.g., GDPR), and (4) coordinate sharing initial findings from data collection back to respondents in community reflection sessions. This consultancy DOES NOT include data analysis or final report writing; additionally, data collection tools will be provided by Oxfam.
