The Rural Water Supply Network (RWSN), in collaboration with UNICEF, recently published a Code of Practice for Cost Effective Boreholes. This document outlines principles that provide a basis for the realisation of economical and sustainable access to safe water through the construction of boreholes in Sub-Saharan Africa. Evaluation of these principles in specific countries underlined the importance of improved contractual procedures and technical specifications for significant reductions in drilling costs.
