Abstract: The performance of 129 boreholes constructed as groundwater intervention projects by governmental and non-governmental agencies in Ife Central Local Government Area, Osun State, Southwestern Nigeria was assessed to appraise the effectiveness of the projects. Out of the eighty-seven (87) boreholes constructed by Government (Federal, State and Local), 51 boreholes (59%) were functional, while 36 boreholes (41%) were non-functional. Twenty-nine (29) boreholes constructed by non-governmental agencies recorded 66% success and 34% failure. Thirteen (13) boreholes constructed by unidentified agencies recorded 8% success and 92% failure. Pump failure, poor maintenance, stolen pump and unidentified causes contributed 36%, 16%, 7% and 41%, respectively to the 45% failure of the boreholes. The groundwater intervention projects are not very effective as only 55% of the 129 boreholes investigated were functional while 45% were non-functional. Borehole maintenance by both the agencies and beneficiaries, and availability of spare parts for the groundwater supply facilities were recommended.
