The magic and mystery of groundwater data

To be effective, drinking water programmes relying on groundwater need good quality and well managed groundwater data. Unfortunately this is an overlooked, “techy domain”. The presentations and discussants on this webinar explain the typical problems of groundwater data collection, management and use. They draw on first hand examples of: groundwater data use in Uganda and the United Kingdom; groundwater databases in 15 African countries (Benin, Burundi, Central African Republic, Chad, Guinea, Ivory Coast, Liberia, Madagascar, Mali, Mauritania, Niger, Senegal, Sierra Leone, Togo and Zambia) and work on transboundary aquifers in South Africa, Namibia and Botswana) followed by of the current realities in Mozambique. There is need for training, quality assurance of data, and for groundwater data collection to become part of drilling contract management.
Presentations and reflections from Lawrence Brown from Hafren Water (UK), Helen Bonsor of the British Geological Survey – BGS (UK), Fabio Fussi of the University of Milano Bicocca, Italy and Andreas Antoniou of the International Groundwater Centre – IGRAC (the Netherlands). Reflections from Brighid O Dochartaigh, British Geological Survey – BGS (UK) and Samo Chirindja Farisse – Eduardo Mondlane University (Mozambique).

Pour être efficients, les programmes d’approvisionnement en eau potable ayant recours aux eaux souterraines ont besoin de données sur les eaux souterraines de bonne qualité et bien gérées. Malheureusement il s’agit d’un domaine jugé trop technique et souvent négligé. Lors de ce webinar les présentateurs et commentateurs mettent en exergue les problèmes typiques concernant la collecte, la gestion et l’utilisation des données sur les eaux souterraines. Ils se basent sur des exemples personnels : utilisation des données des eaux souterraines en Ouganda et au Royaume Uni ; bases de données sur l’eau souterraine dans 15 pays africains (Bénin, Burundi, République Centrafricaine, Tchad, Guinée, Côte d’Ivoire, Libéria, Madagascar, Mali, Mauritanie, Niger, Sénégal, Sierra Leone, Togo et Zambie). Il y a des besoins en formation, en assurance qualité des données et en ce qui concerne la collecte des données sur les eaux souterraines la nécessité de devenir partie du contrat de forage.

Overcoming the Rural Water Supply Scandal of Handpump Corrosion

Handpump corrosion has been known about for over 30 years, the fact that it is a common problem in over 25 countries is a scandal and reflects badly on donors, implementers and governments.
In this webinar, Bony Etti and Jacinta Nekesa from WaterAid Uganda describe their shocking findings from investigating boreholes and pumps (as part of the UPGro Hidden Crisis study) some of which have failed or become unusable within 6 months of being installed. Jake Carpenter, a consultant and former Peace Corps volunteer in Uganda describes the history, theory and practice of corrosion issues and provides practical solutions for resolving the issue. Our discussants, Dr Peter Harvey (UNICEF) and Jess MacArthur (iDE) add their comments on why this avoidable problem is still around and in a lively Q&A session, some positive ways forward are discussed.

Le secteur est au courant depuis plus de trente ans des problèmes de corrosion des pompes manuelles. Il est scandaleux que ce problème soit encore récurrent dans plus de 25 pays, et cela nuit à la réputation des financeurs, des chefs de projets et des gouvernements.
Dans ce wébinaire, Bony Etti et Jacinta Nekesa de WaterAid Ouganda présentent les résultats choquants de leur évaluation de forages et de pompes (dans le cadre de l’étude UPGro Hidden Crisis) dont certains sont tombées en panne ou ne sont plus utilisables 6 mois seulement après leur installation. Jake Carpenter, consultant et ancien bénévole des Peace Corps en Ouganda, reprend lui l’histoire, la théorie et les aspects techniques des problèmes de corrosion en général, et propose des solutions simples et pratiques pour les résoudre. Dans la session Questions/Réponses les participants discutent de ces alternatives à mettre en place pour améliorer la situation.
Dans la version anglaise du wébinaire deux intervenants, Dr Peter Harvey (UNICEF) et Jess MacArthur (iDE), apportent aussi des précisions sur les raisons pour lesquelles ce problème pourtant évitable continue d’exister.

Groundwater Governance

10th March 2015

Two presentations followed extensive discussion. Groundwater risks and institutional responses in Kwale, Kenya (Jacob Katuva, Oxford University) and From Codes of Practice to a Code of Conduct – groundwater governance in Kenya from a drillers perspective (Tom Armstrong, JB Drilling). Practical issues of borehole design and construction, groundwater quality, gender and poverty as well as the realities of the Water Resource User Associations (WRUAs) in Kenya, and plans of the Kenya Water Industry Association (KWIA) were discussed.

Groundwater Resources and Supplies in Africa

24th February 2015

Two research-based presentations by: Joy Obando (Kenyatta University, Kenya) and Dan Lapworth (British Geological Survey, UK). With a focus on selected sites in in Comoros, Tanzania and Kenya, Obando’s presentation sets out key social and economic issues with respect to groundwater resources in coastal East Africa. Lapworth’s presentation examines the changes in water access and realities of groundwater resources in Kabwe, Zambia. The examples, combined with the lively exchange with participants, provide insights into the realities of drinking water for the poor in urbanising Africa. The webinar is facilitated by Jan Willem Foppen (UNESCO-IHE, Netherlands).

Africa Groundwater Research

In this webinar, Jan de Leeuw presented his project’s work in developing and using a decision-support tool to enable a municipality to quantify the risk of developing a major new groundwater source from the Merti Aquifer, in Kenya. John Chilton presented disturbing evidence from Uganda about why handpumps fail and that some of the major problems come from poor installation and supervision in the first place – thus giving communities an uphill struggle to manage their water source sustainably. In the debate afterwards, John Gowing, of the AMGRAF project, and the participants asked some searching questions.
