Design review of the Pounder Rig, following field trials of the prototype

Field trials of the prototype Pounder Rig were undertaken in Mpigi District, Uganda in the second half of 1999. The first phase of these trials gave rise to an initial evaluation of the equipment, which is included here as an Appendix. The trials themselves are fully reported under separate cover (Ball, P and Danert, K (1999) Field Trials of the Prototype Pounder Rig, Uganda, 20 th August – 13 th November, 1999. Report of DFID KAR Project R7126 “Private Sector Participation in Low Cost Water Well Drilling”, Cranfield University). This document is a review of the design of the Pounder Rig, and a discussion of pertinent aspects of its use and management, following the completion of the trials. It forms the basis for the move from prototype to production
