1. Drawing on recent research on the siting and borehole drilling in Uganda, this webinar provides a platform for discussion on turnkey contracts, groundwater data, procurement realities and the regulation of private sector enterprises and consultants for professionals from throughout the world.
    The webinar follows on from a series of four blogs on drilling professionalism inviting comments that were released on the 18th March, 1st April, 15th April and 29th April, as well as the publication of the Guidance Note on Professional Drilling and the UNICEF Toolkit on Borehole Drilling – Planning, Contracting & Management.

  2. Les dysfonctionnements des forages peuvent être dus à des défauts de conception ou de construction du puits. Dans cette vidéo Henry, réparateur de pompes manuelles avisé, apprend les bases pour bien réussir l'implantation, la conception, la construction et le développement d'un puits. Découvrez avec lui à ce propos l'importance du chemisage et des filtres, du massif filtrant et du joint sanitaire, et les conséquences problématiques de l'ensablement dans un forage. Pour aller plus loin sur la conception et la construction des forages, téléchargez Developing Groundwater, un guide gratuit disponible sur le site internet de Practical Action (developmentbookshelf.com/doi/book/10.3362/9781780441290)

  3. Pump failure can be caused by poor quality borehole design or construction. Meet Henry the handpump mechanic as he learns about the basics of good of borehole siting, design, construction and well development. Find out about casing and screen, gravel pack, and the sanitary seal and see that silting is one reason that boreholes fail. To learn more about borehole design and construction, download Developing Groundwater, which is available for free on the Practical Action website (developmentbookshelf.com/doi/book/10.3362/9781780441290)

  4. Créer un forage pour trouver de l'eau n'est pas une tâche facile. La plupart de la construction est souterraine et les marges d'erreurs sont élevées. Les foreurs supportent tous les risques seuls si ils ne sont pas dédommagés pour les puits improductifs. Pour bien gérer les contrats de forage il est nécessaire d'appréhender ces incertitudes et de travailler étroitement avec l'ensemble des partenaires. Les quatre étapes pour obtenir de meilleurs forages sont: (i) préparer une procédure de passation des marchés, (ii) suivre une procédure d'attribution des marchés claire et précise, (iii) gérer les contrats efficacement, à travers notamment une communication régulière, la supervision et le paiement des factures en temps et en heure et (iv) assurer le suivi évaluation après la construction.

  5. Drilling for water is complicated. Most of the construction is underground and much can go wrong. If drillers are not paid anything for dry boreholes then all the risk is passed to them. Good drilling contract management requires an understanding of the uncertainties; stakeholders need to work together. The four steps to better drilling are: (i) preparing a procurement plan, (ii) a systematic contract award process, (iii) professional contract management, including regular communication, supervision and timely payment and (iv) monitoring and reporting after construction.
