If you measure something, how do you know that someone else would get the same result? This is a fundamental question in many fields including medicine and psychology, but it is rarely considered in rural water supply.

If you measure something, how do you know that someone else would get the same result? This is a fundamental question in many fields including medicine and psychology, but it is rarely considered in rural water supply.
This problem became painfully apparent during a recent study of professionalizing handpump maintenance in Uganda conducted by the Program for Water, Health, and Development at the Stanford Woods Institute for the Environment and International Lifeline Fund. Our data collection team had a seemingly straightforward instruction: Count a handpump as functional if it provides water. But different data collectors interpreted the instruction differently. Some would count a handpump as functional even if it took a long time to get a little water. Others counted handpumps in a similar condition as nonfunctional. We needed a clearer, more reliable procedure to ensure that handpump functionality measured by different people would be comparable.
India: home to almost a fifth of the global population. Yet, its rural communities continue to face challenges in accessing water, due to overextraction depleting groundwater, poor recharge, and increased demand for water as industries expand and the rural economy grows. Ensuring water security for the future requires us to learn from the past. Across India, rural populations once met their water needs through ingenious feats of architecture in the form of stepwells (or baolis or vavs). I went to visit Adalaj Ni Vav (Rudabai Stepwell), on the outskirts of Ahmedabad, Gujarat in February 2023. In this two-part blog series, I reflect on the lessons we can learn about the significance of stepwells for India from past uses of Adalaj (part 1) and look ahead the role that stepwells could play in the future (part 2).
What are stepwells?
Stepwells are linear buildings. Steps lead down to landings with pavilions that house two shrines, and columns which make them resemble a room, followed by more steps, until reaching a cylindrical well at the bottom. The roof of one room becomes the floor of the pavilion above. Gujarat’s stepwells range from 60 to 80-feet in depth, with their upper-most landings receiving the most light, screened by walls known as Jalees to provide shade. Stepwell corridors are open to the sky except where it enters a pavilion. The terraces of stepwells are typically marked by noises and splashes as women beat clothes and scour pots, animals drink and children run around. The stepwells are referred to by landmarks (e.g. station vav), goddesses (e.g. Surya Kundi), patrons (e.g. queen) or place (e.g. Adalaj)[i].

Adalaj Ni Vav: a well with a tragic tale
Adalaj Ni Vav is a 75.3-metre-long stepwell laid out in a north-south direction. On my visit, I made my way down one of the three flights of steps arranged in a cross to enter the vav, which are attached to the main stepped corridor leading to the well at the bottom, with an octagonal opening at the top and a pavilion resting on 16 pillars with 4 built-in shrines. The vav was built between 1498-1505 by Sultan Mahmud Begada in honour of Queen Rudrarani, who he promised to marry after it was completed. When the vav was completed, Rudrarani committed suicide by jumping in to the well. Through his grief, the Sultan killed those who built it to prevent another similar vav from being built, who are buried in the graves in the nearby garden i.
Learning from Gujarat’s past links to Adalaj
Adalaj Ni Vav was once a hub for the local community until the British Raj put it and many other vavs into disuse, deeming it unhygienic and introducing taps, pumps and borewells. Rainwater harvesting enabled the community to wash their clothes and feed their animals. Travellers used the vav, built along trade routes to support India’s economic development, as a resting site[ii].
Whilst it is no longer used as a water point, Adalaj’s long-standing spiritual connections to local people can help to sustain the cultural legacy of the stepwell. There is scope to pave a way for the community to continue its traditional purpose as a place of worship. The shrine on the outer wall has long been used and maintained by local Brahmin women to the present day, who worship local goddesses for fertility, health, and family prosperity.
But, it is not just people who stand to benefit from lessons from Adalaj’s past. Birds and animals used to be attracted to the vav as a cool spot, drawn in by food left over from festivals. In an era of global challenges such as climate change, it is important to recognise that the stepwell was once a place where rich biodiversity could flourish.
Moving forward: bridging the history of Gujarat’s stepwells to the future
The history of Gujarat’s rural stepwells reflects the cultural significance they held in the past, and show a need to recognise them as previous places of sustenance and of continued spiritual value. Whilst it is unlikely that Adalaj will once again serve as a water point, it can provide a place for biodiversity to flourish, and has the potential to teach and reengage local communities with their own water management systems for future preservation, particularly in these parts of Gujarat where drilling for petroleum is creating depressions in the water table. Let’s recognise the collective memory of Gujarat’s rural stepwells as historical sites of interest and work to preserve these ancient structures for the future.

After some days of reflection, I want to share my thoughts on the UN Water Conference, which was undoubtedly a historical event for all those committed to the human rights to water and sanitation.
First, I would like to congratulate the President of the UN General Assembly and the UN Secretary-General, as well as the co-host member states, the Kingdom of the Netherlands and the Republic of Tajikistan. For the first time in 47 years, the UN family gathered to host a global event on water; this is in itself a positive achievement. The UN provides an important platform to discuss the fundamental human rights to water and sanitation and I welcome the decision to hold a third UN Water Conference in 2025.
This blog is based on the Accountability for Water action and research programme funded by the William and Flora Hewlett Foundation and managed by the Partnership For African Social and Governance Research (PASGR), supported by Water Witness International, KEWASNET and Shahidi Wa Maji. The full webinar summary is available here.
On 15th December 2022, a global webinar was held to discuss the critical importance of accountability for water. During the webinar, a partnership of organizations led by PASGR and Water Witness presented the findings of their Accountability for Water research program, which aimed to identify specific actions to strengthen accountability in different contexts. The programme partners involved in the research include KEWASNET, Shahidi Wa Maji, WaterAid, Water Integrity Network,End Water Poverty, IRC, and World Bank. Dr Pauline Ngimwa and Dr Muthio Nzau of PASGR introduced the webinar.
Dr Tim Brewer of Water Witness gave an overview of the research programme which started with the global review of evidence carried out in 2019-2020. According to this review, 80% of the research papers on accountability found that interventions contributed to improved water, sanitation and hygiene (WASH) services and water resource management (WRM). Common lessons emerged with clear recommendations for action by governments, civil society, donors and others. While a key lesson is that accountability is context specific, an analytical framework based on the “5 Rs of accountability” can be used to identify specific challenges and opportunities within this framework – the ability to review, explain, and report performance against rules, responsibilities, and obligations, and to react constructively to improve performance through sanctions, incentives, or corrective measures.
The review identified a series of knowledge gaps and questions, including gender, donors, government responsiveness, measurement, and civic space. Based on this analysis, 14 Professional Research Fellows (PRF) working in the water sector in Ethiopia, Kenya, Tanzania, Zambia, Liberia, and Zimbabwe from a range of government, civil society and academic institutions investigated accountability issues in their own contexts. The full list of research topics and researchers is at the bottom of this blog.
The following key takeaways for governments, civil society organizations (CSOs), and donors were drawn from a compilation of recommendations from the research projects .Presenters included Dr Firehiwot Sintayehu (Addis Ababa University); Eunice Kivuva (CESPAD); Chitimbwa Chifunda (WaterAid Zambia), The full list of research topics and researchers at the end of this blog demonstrates the depth and breadth of evidence underlying these recommendations .
Three key takeaways for governments
Laws, policies and accountability mechanisms are essential to support accountability. However, lack of clarity and consistency between sectors and levels, a lack of knowledge and capacity about the laws and mechanisms, and weak enforcement often undermine these. Therefore, the key recommendations are to:
Harmonise, strengthen, and execute laws and policies for water resources and WASH at national and subnational levels,
Strengthen accountability systems and relationships: mechanisms, standards, regulation, monitoring, stakeholder engagement and enforcement including for the private sector,
Build capacity on accountability, develop an accountable outlook and de-politicise accountability systems.
Clear roles and responsibilities and better coordination: Accountability mechanisms are often let down by poor coordination, unclear or conflicting roles and responsibilities and widespread lack of enforcement. Key actions required are to:
Clarify institutional roles and responsibilities between actors for WASH and WRM – eliminate conflicts in functions,
Separate implementation and regulatory institutions,
Strengthen horizontal and vertical institutional and sector coordination across water users through enforceable accountability systems and mechanisms.
Informed engagement with citizens and users: All the researchers found that effective engagement with citizens, citizen groups and water users is essential for accountability but wanting. To address this governments need to:
Introduce or strengthen accountability mechanisms such as public hearings and citizen oversight panels,
Provide Information, education, and mobilisation for communities ensure access for marginalised groups,
Support civil society to vertically integrate social accountability initiatives into decision making at different levels,
Support coordination amongst actors to increase the capacity of rural women and marginalised communities to participate in problem analyses and decision-making processes.
Three key takeaways for civil society,
Activate and institutionalise effective citizen oversight mechanisms. As well as the government actions to strengthen engagement with citizens and water users Civil society organisations need to support this, they should:
Advocate for more legally institutionalised avenues of citizen oversight,
Ensure that citizens’ monitoring and advocacy initiatives are vertically and strategically integrated in decision making at all levels,
Carry out budget tracking throughout the whole cycle from planning to expenditure.
Build capacity, empowerment and organise communities. A very common cause of weak accountability is the low levels of knowledge and capacity of water users about their rights, the laws and responsibilities around water provision and resource management, and how they can use accountability mechanisms. Civil society organisations need to:
Build capacity on accountability mechanisms and support their use,
Strengthen grassroots user groups and associations to participate in decision making,
Support civil society and water users, especially women, to move up the Participation ladder from token participation to active participation, decision making, and control.
Build on what works, like budget tracking, evidence-based advocacy, litigation. There is growing knowledge about successful strategies for strengthening accountability. This research has helped to strengthen a community of practice on accountability and identify examples that others can learn from. Key lessons for civil society are to:
Strike a balance between constructive and critical approaches to advocacy,
Bring strong evidence for advocacy,
Raise awareness of WASH and WRM issues amongst all stakeholders including citizens, government and development partners.
Four key takeaways for donors and private sector
Support governments and CSOs to strengthen accountability frameworks, monitoring and enforcement. Donors can provide financial and political support for the actions for governments and civil society mentioned above. They need to:
Support governments on WASH and WRM accountability actions as above,
Support CSO actions as above,
Support good governance and democratic space for citizens’ voice. Citizens’ engagement is critical to enhancing accountability,
Invest in women’s participation and reaching marginalised people,
Strengthen political will for accountability. Donors can influence government priorities,
Invest seriously in sustainability.
Water investments need to go beyond projects. They need to:
Go beyond procedural & financial accountability. For example strengthen basins planning to ensure responsible industrial water use,
Support budget tracking through the cycle – budget tracking is an effective tool to improve budget performance,
Invest in appropriate technology to support accountable and responsive services, For example digital monitoring of services and water treatment technology to prevent pollution of water resources.
Enhance due diligence. Researchers found examples of very weak accountability in economic uses of water by industrial and agricultural actors. Donors and private investors can help strengthen accountability by requiring:
Stronger due diligence of companies in relation to water use,
mandatory reporting on water,
promoting and enforcing the Polluter pays principle
Be accountable! Donors are major investors in the water sector but often do not fulfil their commitments. For example in Zambia the WASH sector is 80% funded by Donors but only 29% of that was tracked through the budget.
Accountability Mechanisms are needed to enable Governments and CSO to hold Donors accountable for their commitments.
Discussion and next steps
During the webinar, Sareen Malik from KEWASNET, emphasised the importance of legislation to strengthen accountability mechanisms. NGOs can play an important role to advocate for this and bring stakeholders together in Joint Sector reviews as a critical mechanism for accountability, monitoring and reporting.
Martin Atela of PASGR reflected on the role of politics in undermining accountability and suggested that political interference can be mitigated by greater clarity on roles and boundaries of ministerial responsibilities. He also emphasized the need to find ways to work with political elites so they see the value in change
Next steps involve joining the community of practice on accountability for water, to continue learning from experience and to advocate for commitments to strengthen accountability.
Research partners are organising an event at the UN Conference on Water 2023: “Where is the accountability” on Tuesday 21st March, driving a greater emphasis on governance and accountability. This needs to be front and centre of all discussion.
The Research programme is managed by the Partnership for African Social and Governance Research (PASGR) and Water Witness International with financial support from the Hewlett Foundation.

For International Women’s Day, we would like to highlight two participants from the RWSN Mentoring programme for young professionals and women, Fadzai T. Munodawafa-Bhurabhura (from Zimbabwe) and Dr Kerstin Danert (from Switzerland). You can find out more about their experience of mentoring through RWSN below. RWSN plans on launching a new edition of the mentoring programme soon, and encourages women of all ages in the water sector to sign up. To find out more, sign up to become a RWSN member today.
Mentorship is a reciprocal learning relationship in which a mentor and mentee work collaboratively toward the achievement of mutually-defined goals that will develop a mentee’s skills, abilities, knowledge, and/or thinking.
Fadzai’s words:
I am Fadzai T. Munodawafa, a WASH professional with an international Non-Governmental Organisation (NGO) in Zimbabwe. I support teams who implement WASH in the rural communities in Zimbabwe. In addition, I am responsible for managing the drilling unit of the organisation. With such responsibilities as a young professional, I sought to increase my understanding of rural and urban water supply and sanitation as well as groundwater monitoring, which both have a significant bearing on improving access to water for under-privileged communities.
A message of invitation for young professionals in the water sector to join the mentorship programme under the Rural Water Supply Network (RWSN) was shared on the Zimbabwe WASH Cluster platform. I thought this was an opportunity to learn from senior professionals and firm up my career. Following acceptance within the mentorship programme in 2020, I was linked with Dr Kerstin Danert a water sector professional researcher and facilitator.
Kerstin’s words:
I am Kerstin Danert, a rural water supply professional who has been active in RWSN since 2004, when I was still living and working in Uganda. I work as a consultant, with a range of types of work including research, training, facilitation and knowledge-brokering. I currently live in Switzerland.
Fadzai’s words:
My mentorship experience was a flexible one where I would ask questions or a raise discussion point and Kerstin would have a topic for discussion for our scheduled meetings. During our 9-month mentorship relationship, Kerstin and I discussed broadly on topics such as groundwater management, remote sensing and sustainable community-based management of water points key areas that have helped me in my career in the water sector. Kerstin’s experience in sub-Saharan Africa and remote areas made our connection easy as she could relate to my experiences and questions.
Kerstin’s words:
Our mentoring relationship commenced just as I was branching out to start my own company, which unfortunately coincided with the start of the Covid pandemic. It was not an easy time (as we all know), and I was worried as to whether my company would even survive. It very soon became apparent that this would not be a one-way mentorship by any means. Fadzai not only helped me to make contact with field realities (which I was very much missing), but also gave me a lot of support and encouragement regarding my new venture.
Fadzai’s words:
As a young professional, I was not confident speaking in public forums, a weakness my mentor helped me to work on. Now I can confidently speak in professional forums following her encouragement. Our engagement also looked into working on my resume and boost it to showcase the experience and skills I have. In addition, she connected me with experienced drillers and water specialists in Zimbabwe.
Kerstin’s words
Although I have now worked in the water sector for over 25 years always as a consultant, I still remain concerned work may not come in going forwards. Further, I think that I had began to take my years of experience for granted. The exchanges with Fadzai helped me to fully appreciate that I am actually not at the start of my working life, but (hopefully) in the middle of it with a lot under my belt already!
Both of us
Since the mentorship programme under RWSN, we have kept in touch resulting in our participation in the UNHS Climate and Gender podcast on Global Partnership: Gender, Progression and Climate-Orientated Careers (The UNHS Podcast and Spotify) in 2021. The following year, our mentorship led us to work on a report and video documenting the impact stories from participants of online courses on professional drilling by the RWSN
Fadzai’s words:
As a result of my mentorship experience, I can more effectively allocate my time for various activities, connect and confidently engage with other professionals in the water sector as well as have knowledge on key aspects of documentation. I highly recommend other young professionals to join the mentorship program that will build them up in their career within the water sector. Many thanks to the RWSN for this amazing and life changing experience.
Kerstin’s words:
This mentorship brought me closer to the field again. I learned so much from the conversations with Fadzai – and drew insights from her into all of my ongoing assignments, whatever the topic in fact. She always had such insightful contributions to make. And I argue that I was the mentee just as much as Fadzai was. So I encourage others to take the time to get involved in this programme. It has been so rewarding and I look forward to finally meeting Fadzai one day! We have been talking regularly now for three years. A big thanks to RWSN for this chance.

I am sorry to inform you of the passing of Dr. Otto Langenegger, who peacefully left us on 19 February, 2023 surrounded by his family, aged 84.
Dr Langenegger was the pioneer of rapid handpump corrosion. His seminal publications in 1989 and 1994 set the foundation for all that followed in trying to understand and address this phenomenon.
In his eulogy, he was poignantly referred to as a “nomad around water”. He grew up, in humble surroundings, close to Lake Constance in eastern Switzerland, the youngest of six siblings.
His thirst for discovering and learning could not be quenched by his apprenticeship as a radio technician in Winterthur. He was a through-and-through scientist and researcher, moving between subjects throughout his life, and building on the learning from one area as he branched into another. Together with his wife Dorothea, he moved to work in Canada for several years, from where he was able to, amongst other experiences, be part of an expedition to the Arctic, an exposure that he relished for the rest of his life.
Dr. Langenegger and his wife, with their two sons Urs and Thomas, moved back to Switzerland, and he completed his first PhD at the University of Bern in 1973. But he was soon on the move again, this time to Ethiopia, where he worked as a Hydrogeologist with the Christoffel Mission. He was fascinated by the people and culture, and was saddened to have to leave in 1976 due to the difficult political situation at the time.
Dr. Langenegger was not long back in Switzerland, before heading off to Africa in 1981, initially to Ghana, where he worked for the World Bank on the pioneering water well drilling and handpump installation project of its time in West Africa. This position, and the subsequent assignment based out of Abidjan, took him to Burkina Faso, Cote d’Ivoire, Ghana, Mali and Niger.
As a keen observer and compassionate man, Dr Langenegger was both intrigued and appalled by the ‘red water’ problem, coupled with corroding and failing handpumps that he observed in many parts of West Africa during his field work. And so, he set out to understand the causes. Initially using his own allowances to test water quality, he diligently researched this issue. One of his colleagues from the time told me that he stayed in the cheaper hotel in Kumasi – saving money for testing, and filling the bathtub with his tests. He also had his wife, Dorothea, cook plantain with different concentrations of iron-rich water from the rapidly corroding handpumps to see what happened to them. They changed colour.
Anyone working on handpump corrosion is familiar with Otto Langenegger’s seminal publications (1989 and 1994), which have provided the foundation for all that has followed on this topic. His second PhD was in fact on Handpump Corrosion.
After returning to Switzerland in 1989, Dr. Langenegger set up his private consultancy practice, working out of his home in Gais, Appenzell. Overlooked by snow-capped Alpstein mountains, his interest in water found an outlet in learning about the blue coloured snow, high on the slopes. And so once again, this through-and-through researcher set about observing, measuring and interpreting. I would say that Dr. Langenegger’s, keen interest and thirst for knowledge in relation to water was insatiable.
It was 2019 that Dr. Langenegger, who would soon to be known to me by the informal address simply as Otto, contacted me. He had found my own report on Rapid handpump corrosion in Burkina Faso and beyond and wanted to know more. Otto was both disgusted that the corrosion problem had not been fully addressed (after more than 30 years), but was also pleased that it was at least being looked at again. Unbeknown to me previously, he lived just a few stops along the train line from St. Gallen where I am based!
Otto had been out of touch with the water supply world in Africa for a long time, but had, now and then, searched for what may have followed on from his work on handpump corrosion. And so he was aware of the presentation entitled ‘New signs of an old Problem’ at the WaTer Conference in Oklahoma in 2015 by Vincent Casey, Lawrence Brown and Jake Carpenter.
Over the last two and a half years that Otto and I were able to share, he followed all of the ongoing efforts and work to address rapid handpump corrosion – the issue which he has pioneered in the 1980s. He was delighted to be able to talk about the subject, and, researcher that he was, always asked such pertinent questions and put forward ideas.
Throughout his long illness, and even as he grew weak towards the end of his magnificent life, he always wanted to hear the latest news. His delight to hear that the corroding handpumps in Ghana had been replaced in the 1990s is something that will always remain with me. “It was not all for nothing” he remarked, fist in the air, referring to his efforts over 30 years ago.
Dr. Otto Langenegger will be much missed. May he Rest in Peace.
He leaves behind a large family:
Urs and Marika Langenegger-Bohse with their children Tabea, Dominik and Eliane.
Thomas and Anita Langenegger Vogel, with their children Samuel, Jonas, Elias, Rahel and Salome.
In 1983, I moved to live and work in Ghana – some 40 years ago now. Back then, I was the regional supervisor on the 3000 Well Maintenance Unit in Southern and Central Ghana which was funded by the German Development Service under the Rural Water Supply programme. The project was a pioneer of its time, and included drilling boreholes alongside the installation and testing of handpumps in six of Ghana’s regions, as well as the Nanumba district, Northern Region.
We initially installed India Mark II and Moyno pumps, before dropping the Moyno due to technical problems. However, we soon realised that the India Mark II pumps faced corrosion issues. Investigation and testing (as documented by Langennegger, 1989 and Langenegger, 1994) found that the Galvanised Iron components (rods and riser pipes), when installed in water with low pH, had a propensity to rapidly corrode – leading to discolouration of the water and affecting taste, but also causing the pumps to fail prematurely as the rods broke and riser pipes developed cracks and holes and even fell into the borehole. The envisaged idea of maintenance by communities, with assistance from mechanics who could reach villages by motorcycle, was simply not feasible with such installations. Another significant issue related to corrosion of hand pump parts was the water contamination and bad taste of the water. As a result, the water coloured the food and therefore caused the population to stop using the borehole water and forced them to go back to unsafe water sources
We, therefore, had to seek alternatives. This involved field testing and collaborating with the Materials Testing Institute of the University of Darmstadt.
We looked into replacing the galvanised iron components with stainless steel. To ensure the pipes were light, we considered using 3 – 3.5 mm thick pipes, and used a threading that at the time was used in the drilling industry , known as the “rope thread”. Although Atlas Copco had patented this threading type at the time, it was later manufactured in India after the Atlas Copco design period (patent) ended.
Figure 1: Rope thread (Claus Riexinger)
The pump rods presented some challenges as well, since the AISI Stainless Steel grade 316 that we were using was subject to breakage, including the threaded parts. In collaboration with our partners at the University of Darmstadt, we were able to find ways to make this grade of stainless steel more elastic by adding 2-3 % Molybdenum. Other issues with the rods related to the use of rolled thread, which we learned was more durable than cut thread. Incorporating these materials and techniques, we were able to reduce the rod diameter from 12 mm down to 10.8mm, resulting in lighter rods which did not corrode. The only drawback was that the threads could not be cut in the field, but this was not such an issue, as there was no need to cut them when they were installed, or upon maintenance.
Figure 2: Pump installation (Claus Riexinger)
After switching to stainless steel riser pipes, we encountered another issue: -galvanic corrosion between the pipe and the water tank. This type of corrosion occurs when two dissimilar materials come into contact in solution. It was yet another challenge! Fortunately, we were able to solve this problem by replacing the existing flange with a new one made of stainless steel with an insulating gasket, into which the riser pipe could be screwed and prevent any further galvanic corrosion.
Figure 3: Ghana Modified India Mark II Handpump – water tank, spout and flange
After conducting extensive testing and collaborating with the University of Darmstadt over a period of around 4 years, we managed to solve the problem of rapid corrosion of handpumps in Ghana. The improved pump design came to be known as the Ghana Modified India Mark II, and was officially adopted by the Government of Ghana in the 1990s. Its specifications can be downloaded here.
Designing and publishing the specifications for a new pump is one thing, but the other is ensuring that these are adhered to. A series of meetings with government, donors, and NGOs working in the water sector in the 1990s, led to the agreement to no longer use Galvanised Iron. All stakeholders were on board with the change.
Of particular importance was the tremendous support and buy-in of the major donor at the time – KfW (Germany). They agreed to pay for the increased costs of the Ghana Modified Pump on new installations, which at the time was about three times more expensive than the version using Galvanised Iron. KfW also supported the rehabilitation and replacement of the pumps that had previously been installed using Galvanised Iron. As a result, we were able to remove and replace the corroded installations systematically, rather than addressing the issue in a piecemeal manner.
It is estimated that over 4,500 Ghana Modified India Mark II handpumps had been installed in Ghana by the time I left the 3000 Well Maintenance Unit in 1992. Anecdotally, I would say that 90% were working, and of the 10% out of use, they were down for maintenance/repair.
KfW took this design to Cameroon, while Danida took it to Burkina Faso and Zambia. I am not fully aware of what happened next, but I do know that ensuring the quality of stainless steel was a problem in Burkina Faso.
I am very pleased to see that Ghana Modified India Mark II handpumps are now available through the Rural Water Supply Network (RWSN), and hope that these can be of use to other countries that are struggling to overcome the rapid handpump corrosion problem.

However, I have a work of caution too. Although specifications, standards, and clear procurement documents are essential, they are rendered meaningless in the absence of inspection. During my time with the 3000 Well Maintenance Unit and later as an independent consultant, I traveled to India and other places for pre-shipment inspections. I also oversaw the rejection of consignments from India and Europe due to poor quality or manufacturing mistakes. And so, I urge all of you involved in handpump procurement and installation to make sure that you ensure the quality, especially through inspection and material testing.

REAL-Water to coordinate data and actions for the sustainable development of water resources in arid Southern Madagascar.
In Madagascar, there are significant disparities in access to essential water and sanitation services. Currently, only about half of the population (54.4%) has access to vital water services, and just over 10% have access to necessary sanitation services. The situation is particularly challenging in Southern Madagascar, where various development issues, such as population growth, changes in land use, and worsening dry-season water shortages, are present. These difficulties are exacerbated by poverty, which hinders water resource development, leads to poor infrastructure, and contributes to food insecurity.
To guide regional programming that considers the development and humanitarian requirements, USAID Madagascar has commissioned REAL-Water to assess water resources and infrastructure needs. The program will entail specific activities, including a literature review of water development activities, data collection on existing and planned water infrastructure, analyses of remaining water resources and infrastructure needs, and planning for future investments.
The six districts of interest covered in the assessment are shown on an I-digital elevation model (from the Shuttle Radar Topography Mission). Small gray and green polygons indicate areas of human settlement (“Settlement Extents”) from the GRID3 DATA HUB. Each settlement extent type (built-up area, small settlement area, and hamlet) is included, with built-up areas depicted in green).
Professional Drilling Management & Groundwater Resources Management
Thanks to funding from the Federal Institute for Geosciences and Natural Resources (BGR) in Germany, 2022 saw Ask for Water GmbH, together with the Africa Groundwater Network, Cap-Net UNDP and several other partners (see below) develop and run two online courses on groundwater. The courses strengthened the capacity of staff of governments, NGOs, the private sector and academia in African member states and beyond.
The courses, hosted by Cap-Net UNDP, and offered free of charge to participants, were entitled Groundwater Resources Management and Professional Drilling Management. Each course was specifically developed for professionals working on these issues, or responsible for decision making.

Professional Drilling Management Course
Drilled water wells are vital to achieving universal clean drinking water, providing safe, affordable, reliable and available water sources. To ensure that the water wells or boreholes are built to last, they must be drilled, developed and completed in a professional manner. Key elements of a professional drilling sector are robust procurement, contract management, siting, borehole design, construction, and supervision. Furthermore, the management of the groundwater resources must also be considered and support provided to long-term maintenance if services are to last. Unfortunately, in many countries it is difficult to develop skills in these areas due to a lack of training and mentoring opportunities.
The 2022 online course on Professional Drilling Management provided participants with a comprehensive overview of the different aspects of drilling management, specifically (i) groundwater data and siting; (ii) procurement and contract management (including costing and pricing; (iii) borehole drilling and supervision and (iv) legal and institutional frameworks. In the last of five modules, participants were encouraged to reflect upon and share actions that they as individuals and as organisations could take to raise drilling professionalism in the context in which they work. From the 781 people who applied for the course, 314 were selected, of which 209 were active participants. A total of 162, equivalent to 78% of the active participants passed the course.

Groundwater Resources Management Course
An estimated 50% of the global and 75% of the African population rely on groundwater for their drinking water supplies. Groundwater supports social and economic development and will become increasingly important in the face of climate change, as groundwater resources are often less affected than surface water by climate change impacts. If groundwater is to provide reliable, safe and sustainable water supplies now and for future generations, the resource must be well-managed. This requires consideration of the entire system of policies & laws, strategies & guidance, monitoring & management as well as investments & projects. Good groundwater management needs sound capacities in water authorities. But at same time, as many elements of groundwater management fall in other sectors, a general understanding of groundwater management principles in sectors like agriculture and urban planning is key for its successful implementation.
The 2022 online course on groundwater resources management provides participants with a comprehensive overview of the multiple factors that impact upon groundwater. It was a self-paced course and was hosted on the virtual campus of Cap Net/UNDP.
The course comprised 5 modules; each with a short introduction, goal, learning objectives and orientation video, as well as mandatory videos and reading materials:
Module 1: Characterization of Aquifer Systems from a Management Perspective
Module 2: Groundwater monitoring and data/information management & communication
Module 3: Groundwater quality and source water protection
Module 4: Groundwater regulation, licensing, allocation and institutions for aquifer management
Module 5: Transboundary aquifers in Africa: Approaches and mechanisms

What next?
The Rural Water Supply Network (RWSN), Ask for Water GmbH, the Africa Groundwater Network (AGW-Net), Cap-Net UNDP and partners would like to offer these courses on an annual basis. We are currently looking for sponsors/funders to make this possible. In case you are interested, please contact us via info@rural-water-supply.net.
