Acknowledgements: The Kitui County Government would like to acknowledge the financial support received from the United States Agency for International Development (USAID). Further, the Kitui County Government appreciates its longstanding partnership with the University of Oxford and UNICEF Kenya through various collaborating programs, including the DFID-funded REACH Program. The leadership received from Emmanuel Kisangau, Kennedy Mutati, Philip Nzula, Augustus Ndingo, and Hope Sila — all from the County Ministry for Water Agriculture and Livestock Development — throughout the audit exercise is appreciated. The sub-county water officers were instrumental in logistics planning and in providing liaison between the field audit teams, communities, and County Ministries for Agriculture, Water, and Livestock Development and Administration and Coordination. A team of local enumerators led field data collection: Lucy Mweti, Grace Muisyo, Abigael Kyenze, Patrick Mulwa, Lydia Mwikali, Muimi Kivoko, Philip Muthengi, Mary Sammy, Ruth Mwende, Peter Musili, Annah Kavata, James Kimanzi, Purity Maingi, Felix Muthui, and Assumpta Mwikali. The technical advice and guidance received from Professor Rob Hope of the University of Oxford and Dr. Andrew Trevett of UNICEF Kenya throughout the planning, data collection, analysis, and preparation of this report is very much appreciated. Front cover: This Katanu Hand pump was developed in the late 1990s by the Government of Kenya and is the main water source for Nzamba Village in Ikutha Ward, Kitui.
