In the rural water scheme projects across sub-Saharan Africa, the participatory Community Based Management model has become the norm. Through initial financing by oustide funders, the goal is for communities to independently take on the financing of the operation and maintenance (O&M) of the improved water schemes, thereby ensuring sustainability and functionality of the pumps. Evidence has been gathering, however that this model, combining ideals of collective action with the logics of commodification, has been frequently failing, one in three hand pumps in Africa are out of function, and communities struggle to meet the financing needs of O&M in infrastructures which perpetuate isolation. This, however, does not lie fully in the fault of the communities, or implementation, but also in theoretical downfalls of the CBM. Looking at a community-based rural project in the Tikar region of Central Cameroon as well, this research reveals the limits of CBM to achieving sustainable water access, as well as reveal new angles and paradigms to pursue.

Many rural communities in arid areas of the world make extensive use of perennial water supplies retained within the sediment of a river channel. This naturally filtered water provides for their basic subsistence. A general term applied to the abstraction of water from river sediment is sand-abstraction. Ephemeral and seasonal rivers primarily drain the dryland regions of the world. These arid regions are typically subject to extensive environmental degradation with a consequent high degree of surface erosion. As a result, many of the rivers have become sand rivers, filled with copious amounts of sediment. Most arid areas are subject to occasional rainstorms and flash floods that immediately drain to waterways and saturate the sediment within the river channel. In larger rivers a perennial supply of water is maintained within the sediment. Despite a perceived potential for this water resource there has been little development of any small-scale technology that is suitable for use at a basic rural level. A research and study programme was instigated to assess fully, the potential of such a resource. Field research was undertaken to characterise typical sand rivers and to assess the water storage and water loss and retention factors within river sediment. A check list for identifying possible sand-abstraction sites was devised. In the process of this study the advantages of storing water in sand was fully appreciated and attention given to the development of initially less suitable sites in serious water deficit areas. Systems for efficient abstraction of water were reviewed and designs formulated for the fabrication of equipment to mechanically draw water from river sediment. A series of well-screens, well-points, infiltration galleries and caissons have been designed and initial tests have been conducted under field conditions. Simple technology handpumps that it was considered could be operated, maintained and repaired by rural communities using locally available materials have been developed in conjunction with the abstraction equipment. In consultation with rural people an analysis was made of the technical and sociological requirements that are considered essential for the sustainability of technology suitable for use by disadvantaged rural communities. Both practical and literature research has indicated the latent possibility of this technology. Interaction has been maintained with four communities throughout the research and development period and contributions and indications received are that there is a need to develop such a water source with an upgraded technology. The conclusion from the work undertaken is that development of the technology is worthwhile and that greater efforts should be made to promote it at a small-scale, rural level. In addition the potential to provide clean water in arid regions from such a lowtechnology application should be drawn to the attention of professional water engineers.

Rural water supply and sanitation in low and middle income countries face the same challenges now as in the 1970s. Despite massive efforts in providing communal “borehole with handpump” and “improved latrines” to improve the lives of millions of people, this traditional approach to development is failing to deliver long lasting improved services - even if for the last 40 years many attempts have been made to solve problems in the approach. The main research question is “Can low-income rural families pay for rural water supply and sanitation?” This thesis has analysed household poverty and costs on water and sanitation services in Mozambique and Ghana based on 3,049 surveys collected between 2009-2010 by the IRC International Water and Sanitation Centre WASHCost project. Evidence shows that even extreme poor households can and do pay for improved water and sanitation services. However, households prefer to pay for more expensive services to reduce the distance required to collect water instead of paying for the cheaper maintenance of communal (further away) sources. For sanitation, without targeted support towards the poorest, improved latrines might be unaffordable. Also, without follow up support, behaviour change and health impact will not be sustained. Small increases in the wealth of the poorest have a large impact on the services demanded in terms of quantity, distance and time spend as well as an increase in the level of capital and maintenance expenditure. Ultimately, the world now is not the same as in the 1970s and for achieving universal sustainable coverage for water and sanitation we need to rethink the failed traditional approach to development in low income countries with a deeper understanding of the market segmentation in the lowest quintile of the population and their real aspirations and demand.
