Author: MORGAN, P. and A. KANYEMBA
Year of Publishing: 2012
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.

Year of Publishing: 2014
Publisher: Rural Water Supply Network
Institution: RWSN/UNICEF

La présente note pratique est destinée aux entreprises de forage et aux sociétés qui gèrent ou participent à des projets de forage. Grâce à une approche par étape, elle donne des directives claires sur la manière d’analyser les coûts et de déterminer les prix pour la réalisation de forages. Elle fournit également des conseils de ges-tion en soulignant les réalités propres à de nombreux pays d’Afrique subsaharienne. Sa lecture vous permettra d’être mieux à même de calculer les coûts des forages, de réfléchir aux prix et de faire face aux réalités commerciales.

L’analyse des coûts et la détermination des prix passent par cinq étapes: (1) l’identification des coûts de fonctionnement de base de votre entreprise, (2) l’analyse du dossier d’appel d’offres, (3) la définition des catégories de coûts, (4) le calcul des coûts et (5) la détermination des prix. Lors de chaque étape, plusieurs points clés doivent être pris en compte. Les coûts se décomposent comme suit: implantation du forage, amenée, forage, équipement/complé¬tion, développement du forage/test de pompage et installation de la pompe. La présente note fournit des exemples pratiques et éprouvés qui permettent de comprendre aisément la méthode d’analyse des coûts et aborde également les devis quantitatifs, les procédures d’appel d’offres et la gestion des risques et des incertitudes. Les auteurs fournissent par ailleurs des conseils pour une gestion efficace de la procédure.

Baptist Drilling

Author: CLOESEN, P.
Year of Publishing: 2007
Publisher: unpublished
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.

Author: Tom Heath, Philip Tibenderana, Richard Carter,Kerstin Danert & Etsegenet Berhe
Year of Publishing: 2009
Publisher: RWSN
Institution: Cranfield University, UNICEF, SDC, Skat

This Borehole Costing Model is a spreadsheet in Microsoft Excel 2003

Once set up the model can quickly calculate the actual cost of a borehole (not the price). The first time the model is used it requires the unit costs to be entered for different materials and rigs. The model was built by Tom Heath, Richard Carter and Kerstin Danert. The model consists of three components: Model Unit Costs, Borehole Specifications and Results.

Capitalisation D'Experiences sur les Forages Manuels a Madagascar

Downloads: 97


Author: PRACTICA
Year of Publishing: 2012
Publisher: UNICEF
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.
