Abstract: There seem too little or no management plan to safe-guard groundwater extraction and ensure sustainability, even though, over 80% of the rural areas in Ghana, which make up about 70% of Ghana’s population, depend on groundwater as a source of portable drinking water by means of mostly boreholes, hand-dug wells fitted with hand pumps. This study provides safemeasurement as a framework to manage and ensure the sustainability of groundwater extraction in Upper EastRegion of Ghana. Mathematical relations to estimate the timesand thetotal number of peoplerequired to exceed the safe yields of selected boreholes had been developed. The study revealed that (7) out of the (28)selected boreholes are being over-pumped; (2) of the boreholes currently have less than (25) years to be susceptible to over-pumping and (19) boreholes have more than (25) years to be susceptible to over-pumping. The study has also estimated the maximum number of people each of the selected boreholes could serve. Recommendations has been made for the estimation of safe on all boreholes in the Districts of Ghana to help all stakeholders to be able plan and monitor yields of boreholes to ensure sustainability of rural water supply in Ghana; Spatial Distribution Map of all boreholes and their safe yields must be developed to facilitate monitoring activities. Further studies are on-going to ascertain the current states of those boreholes which are currently being over-pumped.
