Tips for Groundwater Success: A Sponsored Seminar at the 7th RWSN Forum, Abidjan

Are you involved in groundwater development for rural water services? Come along to this one day seminar to learn more about how to develop groundwater for safe and sustainable water supplies. We will be discussing many aspects of groundwater development, from data and information that can help us understand groundwater resources, to technologies in borehole construction and solar pumping for the delivery of effective water supplies.

Why should I come to this seminar?

This one day seminar – An Understandable Approach to the Development and Use of Groundwater – aims to take some of the mystery out of groundwater development and provide useful, practical information to help you develop effective groundwater supplies.

Groundwater makes up almost 30% of the world’s freshwater reserves, and more than 95% of the available, unfrozen fresh water. Given its broad geographical distribution, general good quality, and resilience to seasonal fluctuations (as compared to surface water), groundwater holds the promise to ensure many communities an affordable, safe and sustainable water supply.

Groundwater is sometimes referred to as a hidden asset – it occurs underground therefore can’t be easily seen or visualised, and is often difficult to understand due to the many varying factors influencing its behaviour, from geology, topography, and climate to land use, soil type and human activities.

What will I learn?

To develop groundwater in a safe and sustainable way we need to understand it. And to understand groundwater we need good data and information, which is often hard to find. The first half of the seminar will seek to answer the questions:

What data and information is needed to understand groundwater and develop it sustainably?

How can we effectively collect and store groundwater data to produce a high quality body of information that is accessible, convenient, affordable, manageable and useful for current and future groundwater development projects?

We will look at data at different scales – from international initiatives down to local, site-scale data – but will be focussing at the country-scale with an introduction to the Africa Groundwater Atlas and case studies of national groundwater data collection and storage from West Africa. Participants will have the opportunity to discuss some of the issues they have experienced with all aspects of groundwater data (collection, storage, management and use) and we will try to offer practical solutions for the future.

The second half of the seminar will focus on practical groundwater development, demonstrating how proper borehole construction, and solar pumping and distribution solutions can provide safe and accessible water that is cost-effective and sustainable for those most in need.

We will seek to show how borehole construction and maintenance can help protect groundwater sources, providing a drinking water supply that is free of e-coli and will last for generations. Participants will also receive tools and guidance for writing borehole specifications to help ensure that groundwater sources are safe and sustainable.

From borehole construction we will then move on to solar pumping and distribution technology, demonstrating that this is often a viable and smart option for potable water services in rural development, particularly where poor groundwater quality or high population density and growth limit the applicability of boreholes fitted with hand pumps. We will show several case studies, from single point supplies to full distribution networks, which highlight low failure rates and overall life-cycle costs, and discuss the key considerations for designing, constructing and implementing solar powered water supply systems.

Who should come to the seminar?

 The seminar is aimed at anyone with an interest in rural water services, and in particular groundwater resources and water supply. We hope to include a range of professionals from all types of organizations and at all levels – from government staff, NGOs, private sector practitioners and academia.

 Who is running the seminar?

The seminar is being sponsored by the UPGro research programme (Unlocking the Potential of Groundwater for the Poor) and Water Mission and will be run by a range of groundwater experts from across Africa, Europe and the USA.

The RWSN Forum – a once in every five-year opportunity!

Rural Water Supply Network - blog

forumThe 7th RWSN Forum in Abidjan is only two months away. Most of the authors of papers, posters and films have now been informed of their acceptance, and we are progressing well with the logistics for the event. I have to say that the team spirit (with 50 reviewers) as well as the joining of hands for the seminars has been outstanding. And thanks to our generous forum sponsors for enabling us to organise this event. I am delighted to see such openness for organisations to link up and work together to prepare sessions in which the forum participants will be able to learn from others, and share.

The programme is driven by the you – RWSN members who made their submissions as well as agencies and groups who have developed the sponsored seminar programme for the Friday. There will be plenty to learn on sustainable services; groundwater and…

Plenty of interest in the Africa Groundwater Atlas in Montpellier

The room is packed as more than 50 people sit and stand to listen to Brighid O Dochartaigh present the Africa Groundwater Atlas. Interest in this initiative this week at the 43rd IAH Congress in Montpellier is high; but I think that this is merely a drop in the ocean and interest will grow in the coming months and years as it becomes more widely known and used.

So what makes this atlas so important?

Well, lack of available, robust information on groundwater constrains safe and sustainable development of the resource. In fact, there is actually lots of information out there, but it remains dispersed and often hard to find; whether on bookshelves, buried in archives, on somebody’s computer or behind journal pay walls. Building on the SADC Grey Literature archive, the Africa Groundwater Atlas and Literature Archive is drawing this information out, and making it available to the public.

What is actually in the Atlas and Literature Archive?

The Atlas provides a consistent overview of key aquifers for 51 countries in Africa. Maps, tables and narrative descriptions provide an overview of the hydrogeology, groundwater status and management of these countries. The Atlas also includes supporting data on climate, surface water, topography, soil, land cover, and geology. It can help you to find out who is who in groundwater in a particular country, and is an ideal place to find out what has already been written for a particular country or region.

If (like me) you are not a hydrogeologist the Atlas is a great starting point for understanding the groundwater resource; and if you are a hydrogeologist, you are likely to be delighted to see the amount of information that has been pulled together.

The Atlas provides new country-scale geological maps together with consistent summaries of the major formations in each country. Some countries have more information than others. However, the team at the British Geological Survey working on the Atlas are reaching out to collaborate with others to improve what’s already there.

Currently, the literature archive is the most comprehensive index of African groundwater literature in the world. It provides a phenomenal index of literature, with over 7000 documents on groundwater from across the continent. The library includes unpublished reports from 1897 to 2014, as well as links to academic papers. While the sheer number of entries may sound overwhelming, the powerful indexing system with keywords, free search possibilities and geo-referenced reports (for 2000 documents) makes searching for information remarkably easy. Just try it!

Looking forward

The Atlas and Archive are not finished! There is still much to do in order to draw out more information and reports, and improve the descriptions for several countries in the Atlas. So I ask those of you with groundwater information that you would like to share to please contact the team at the British Geological Survey (AfricaGWAtlas@bgs.ac.uk) to contribute to the Archive and Atlas. While the Atlas has not included detailed groundwater data, the UPGro project GroFutures is trying to bring together long-term groundwater data and form a network of African Observatories so that those holding the data can work together to improve the understanding and management of groundwater for the African continent.

Finally – What has made the Atlas possible?

The Atlas and literature archive are funded by UPGro (Unlocking the Potential of Groundwater for the Poor), a seven-year UK-funded research programme that runs up to 2020. The Atlas was prepared in collaboration with the International Association (IAH) Burdon Network and was only possibly thanks to more than 50 co-authors working on groundwater across the African continent.20160927_101208atlas_2
