posted on 12.02.2018, 15:08 authored by Kerstin Danert, Richard C. Carter, D. Adekile, A. MacDonald, Erich BaumannThe paper sets out a conceptual framework for Cost Effective
Boreholes (CEB) in subSaharan
Africa.
Using examples from the literature, it sets out six key factors and discusses thirteen elements that affect
CEB. The elements are: operation and maintenance procedures; preference for local private sector
drilling; borehole standards and designs; drilling equipment; procurement processes; contract
packaging; programme and contract management; siting; construction supervision; test pumping
requirements; evaluation of groundwater resources, hydrogeological data collection and storage; and
regulation and private sector professionalism. Adherence to basic principles with respect to these
elements can improve CEB provision. However more investment in human resource development,
institutional strengthening, better monitoring and more transparent reporting is required. The thirteen
elements of the CEB conceptual framework could be used to benchmark the drilling sector in a particular
country and thus raise incentives to make improvements but this requires international as well as
national endorsement.
