Inspection of the Bush Pump head is normally undertaken by measuring the parts with callipers, measuring tapes and rulers etc. In this case a series of templates has been prepared which can be held against the pump head and its parts to make an immediate check of the accuracy of the various components and the alignment of the pump head. In the B type Bush Pump, the alignment of the head is particularly important. | »
In rural areas where hand pumps are commonly used, extracting wa-ter from ultra-deep boreholes (up to 150 metres) poses a significant problem for communities since this is beyond the design limit of standard hand pumps. Demand for climate-resilient, ultra-deep hand pump technology is growing due to dropping global groundwater levels, along with the need for government policies to enforce best practices for year-round, safe water supply.
This paper provides a case study of a practice-based overview of how the governments initiated an update of policies enabling the use of the LifePump in both Zambia and Malawi | »
The provision of safe water requires high initial investments for the construction of the water supply systems. lt is generally assumed that countries, like Ghana would for years to come depend on external donor support to cover the initial investment cost for the development of infrastructure for rural water supply. Experience in the past has shown that these substantial investments are often endangered as the water points fall out of service after a short period of time because of lack of adequate maintenance. | »
UNICEF Madagascar has been supporting rural water supply and sanitation activities in Madagascar for over ten years. The Water, Environment and Sanitation (WES) desk of UNICEF works with Ministry of Energy and Mines (MEM), Government of Madagascar, on a number of water supply initiatives. One of these projects, in the southern part of Tulear Province (also known as the South - Sud), comprised of drilling wells and installation of 150 lndia Mark ll handpumps in the vicinity of Antanimora. This is referred to as the AAEPA Project later in this report. The installation handpumps in the AAEPA Project was completed during 1994-96 and has since then been supported by UNICEF for its operation and maintenance (O&M) with supply of spare parts. lt has gone through a number of reorganisations of its O&M system.
UNICEF Madagascar appointed Raj Kumar Daw, Project Officer - Handpump Technology Network, (PO-HTN) from UNICEF, lndia Country Office, New Delhi, for this study. The study was carried out during 5-29 July 2004. | »
Every year UNICEF WES projects are purchasing large numbers of handpumps. The promotion of low cost technologies by UNICEF has had a profound impact on the implementation of the projects. UNICEF has followed the policy to standardize the types of pumps used. ln some countries that achieved total self-sufficiency in production of handpumps the standardization policy has been acclaimed as the reason for the success. Recently standardization has been criticized for restricting free market forces and suppressing the development of local private industries in smaller countries.
The scope of this study was to collect data on handpump performance in several countries in West Africa. UNICEF WES projects vary in design and execution from country to country.
Projects in Mali or Burkina Faso operate in a completely different environment then in Nigeria.
Accordingly the findings and the recommendations contrast for each country. lt is however also possible to find common denominators about the factors that influence the performance of the pumps. These collective aspects should be considered for the formulation of future strategies. | »
