Abstract

Handpump technology is documented as being the best option for the water supply of rural communities in the developing world. However, it has been observed that the amount of available handpump models significantly drops as water tables get deeper. Many handpumps are therefore expected to operate beyond their design specifications, which is responsible for many failures of handpump projects. This paper compares a total of 12 ultra deep-well handpumps (UDWHPs), with a pumping lift higher than 60 m, in terms of technologies, materials, outputs, costs and maintenance potentialities.

A comparative study between “Rope pumps” and conventional piston pumps on water quality and other sustainability parameters Appropriate technologies for rural water supply

Publisher: Fondazione ACRA-CCS, SHIPO
Institution:

In Tanzania there now are some 5000 Rope pumps both for small communities and Households. To compare Rope pumps with piston pumps like Afridev and Nira pumps regarding water quality, cost per capita and other aspects, the organisation ACRA effected a Comparative study. Some conclusions of the study are:
- Rural communities do not prefer piston pumps above Rope pump
-The water quality of tested Rope pumps is lower than Piston pumps but this is mainly due to bad installation. If installed right there is not much difference in water quality.

A preliminary study of training artisans in upgradeable techniques for family owned wells

Publisher: Aquamor Pvt Ltd
Institution:

Several years ago Zimbabwe embarked on a program of upgrading family owned wells. This program was fully endorsed by the GOZ and operated under the MOHCW. The program has been well documented in papers and other publications. This program was based on the fact that for many decades individual families had chosen to upgrade their own wells privately and outside the formal GOZ rural water supply and sanitation program.

An Assessment of Hand Drilling Potential in Upland and Lowland Malawi MSc Thesis Academic Year 2006/7

Downloads: 25


Author: SUTTON, I.
Year of Publishing: 2007
Publisher: Cranfield University
Institution:

Hand drilling methods can offer low cost, rapid access to shallow, unconsolidated aquifers typically found in dambo environments (seasonally waterlogged African wetlands).
This thesis presents the findings from an evaluation of three hand drilling techniques (augering, percussion drilling, and borehole jetting) regarding to their suitability for groundwater supply in upland and lowland dambos in Malawi.

An Assessment of the EMAS Pump and its Potential for Use in Household Water Systems in Uganda University of South Florida MSc Thesis

Institution:

Rural improved water supply coverage in Uganda has stagnated around 64% for a number of years and at this point more than 10 million rural people do not have access to an improved drinking water source. It has been recognized that progress toward improved water supply coverage and increased service levels may be gained through Government and nongovernmental organization (NGO) support of private investment in household and shared water supplies, commonly known as Self-supply.
There are indications that low-cost wells and underground rainwater tanks are applicable in many parts of Uganda and could be paired with an EMAS Pump to achieve significant affordability for Self-supply household water systems. Recommendations are provided in terms of the feasibility of introducing the EMAS Pump as a part of Self-supply strategies in Uganda.

An Evaluation of the BluePump in Kenya and Gambia

Publisher: University of Technology Sydney & Oxfam
Institution: Institute for Sustainable Futures

This report presents the results of an evaluation of the Fairwater BluePump, an emerging rural water supply technology in sub-Saharan Africa. Claims about the BluePump’s durability and minimal maintenance requirements have provoked significant interest within the rural water sector. This evaluation set out to assess the suitability of the BluePump as a rural water supply technology, taking into account its operational performance, the experiences of water users, the views of local stakeholders, and the broader contextual factors that impinge upon its sustainability.

Institution:

Baptist drilling is similar to hand sludging, with some percussion drilling combined. The main difference is that while sludging relies on a person's hand at the top of the drill pipe as a valve, the Baptist method uses on a valve at the bottom of the drill pipe.

Capitalisation D'Experiences sur les Forages Manuels a Madagascar

Institution: Practica Foundation

Des techniques appropriées au contexte malgache et adoptées par les opérateurs :
well jetting, rota sludge et madrill. La recherche action est porteuse d’améliorations constantes et elle apporte une réponse aux contraintes rencontrées par les utilisateurs. Avec plus de 2000 forages réalisés le secteur du forage manuel a acquis sanotoriété en dépit de son absence dans la politique nationale du secteur eau. 4 fois moins cher que le forage motorisé le coût des forages manuels pratiqué à Madagascar est 2 à 3 fois moins élevé que dans les autres pays d’Afrique.
Un potentiel à confirmer pour donner une idée du marché et de l’impact attendu. Les standards d’équipements sont disparates et la définition d’un ensemble de normes techniques détaillées pour les forages manuels est indispensable.
