    Design review of the Pounder Rig, following field trials of the prototype
    (1999-11-01T00:00:00Z) Ball, Peter D.
    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

    Field trials of the prototype Pounder Rig, Uganda, 20th August - 13th November 1999.
    (1999-11-01T00:00:00Z) Ball, Peter D.; Danert, Kerstin
    A prototype low-cost drilling rig was imported to Uganda in August 1999 and handed over to Mpigi District Government. Field trials of this machine were undertaken between 20 th August and 13 th November 1999. This work was enabled through a tripartite Memorandum of Understanding between the Cranfield University/DFID Low Cost well Drilling Project, the Directorate of Water Development (DWD) of the Government of Uganda, and the local Government of Mpigi District. A total of fourteen holes were drilled in a range of geological formations, and six of these were equipped with U3 handpumps installed by the direct install method (screen directly attached below pump cylinder, with rising main doubling as well casing). Of these six, one gave inadequate yield, while the other five were put into use as community water supply wells. The trial of the prototype Pounder Rig offered much opportunity to learn about its capability, the practicalities of well construction by the direct install procedure, and the acceptability of the technology to the Ugandan crew. A full design review followed the field trials, and this is reported under separate cover. A number of practical issues arose during this period, including methods of crew payment, funding of trials, logistics, and conflicts between the requirements of drilling trials and the expectations of rural communities. These were addressed as they arose, but with the benefit of hindsight they could no doubt have been resolved in better ways.

    Hand Sludging: A Report from North West Bengal.
    (1999-03-01T00:00:00Z) Ball, Peter D.; Danert, Kerstin
    The Low Cost Drilling Project (Cranfield University/DFID/Government of Uganda) is developing a modification of the traditional Asian sludging technology for use in Africa. As part of the technology research a visit was made to north India to observe and measure various characteristics of this well drilling technique. The report describes these observations and draws conclusions for the Low Cost Well Drilling Project.

    Specification and drawings for the pounder rig: a human-powered drill rig for constructing shallow small diameter wells for domestic and agricultural water supply.
    (2007-07-01T00:00:00Z) Ball, Peter D.; Carter, Richard C.
    Despite all the efforts to date to improve access to safe domestic water supply and sanitation in less developed countries, still between 1 and 3 billion people lack these essential services. The causes of this situation are complex, and are not to be resolved through technology alone. However, it is widely accepted that two broad sets of conditions (among others) need to be in place in order for the situation to improve – technologies which are affordable and manageable by user communities, and the institutional arrangements by which communities can gain access to such technologies. This document is one contribution from one project in one country (Uganda) within which an attempt is under way to address these issue
