How three handpumps revolutionised Rural Water Supplies: the Afridev

1980 to 1990 was the International Decade of Water Supply and Sanitation and the greatest hand-pump project began.How Three Handpumps Revolutionised Rural Water Supply

In the new publication “How Three Handpumps Revolutionised Rural Water Supplies” from RWSN, Erich Baumann explains how three handpumps, the India Mark II, the Afridev, and the Zimbabwe Bush Pump were developed and Sean Furey explores what lessons can be learned for scaling up WASH technologies today.

As part of that UNDP and the World Bank established a joint Water & Sanitation Program (WSP, which still exists as part of the World Bank) and one of its flagship projects was the Hand-pump Project, led by Saul Arlosoroff, which rigorously tested all the hand-pumps around the world that they could get their hands on. Their final report “Community Water Supply: the Hand pump Option” (1987) is still the defining text in hand-pump literature.

The hand-pump project also defined Village Level Operation & Maintenance (VLOM), the concept of making hand-pumps easier to maintain by the users so that minor breakdowns could be repaired quickly.  The India Mark II was not a VLOM pump because it required specialist tools and some skill and strength to make repairs to the pump cylinder down in the borehole. This was addressed through a design revision, imaginatively called the India Mark III. However the hand-pump team throught they could still do better and so two handpump design projects began.

How three handpumps revolutionised Rural Water Supplies: the India Mark II

How Three Handpumps Revolutionised Rural Water Supply1974: UNICEF reviewed their water supply programme in India. The results were shocking: of the tens of thousands of wells drilled over the previous seven years, 75% were not supplying water.

In the new publication “How Three Handpumps Revolutionised Rural Water Supplies” from RWSN, Erich Baumann explains how three handpumps, the India Mark II, the Afridev, and the Zimbabwe Bush Pump were developed and Sean Furey explores what lessons can be learned for scaling up WASH technologies today.

In the mid 1960s, drought ravaged India, and the Government of India asked UNICEF for help with improving access to water through borehole drilling. In the following years, the emergency drilling campaign evolved into a broader national programme to improve rural water supplies, but the attention was focused on the drilling and the boreholes. No one gave the hand-pumps that went on them much thought. That all changed in 1974.

reflections on Everyone, Forever and lifecycle costing in Honduras

Stef Smits's avatarwater services that last

Anyone who works in the water sector cannot have missed the various consultations and debates on the post-2015 goals for water and sanitation, with the official one taking place here, but also good online discussions, such as the one on The Broker online. At the same time, technical proposals have been developed by working groups on water, sanitation and hygiene, as nicely presented here by my colleague Catarina Fonseca. The consensus in both the technical proposals and the discussions around them is the vision of universal coverage. The difference lies in the time frame: can it be achieved in our life time? Or is that just wishful thinking? Over the past year, this blog has paid lots of attention to the “Forever” side of “Everyone, Forever”, as Water For People have so compellingly called it. For the coming period expect more posts here on the…

Update from the WASHtech project

dietvorst's avatarWASHTech, THE project (2011-2013)

Sustainable WASH services can only be achieved if the technology used to provide services is sound enough for the specific context. Too often, however, water and sanitation services stop because the WASH technology no longer functions or is too complicated for the context which it’s in. New WASH technologies are promising successful solutions but are often not considered.

WASHTech, an action-research project, is developing and testing processes and tools to perform context-specific validations of potential WASH technologies. WASHTech also aims to successfully introduce the validated technologies into certain contexts such as countries, districts, or sub-districts.

Come and be part of this pre-launch on Friday 12 April 2013 from 09:30 – 11:00 hrs and learn how the “Technology Applicability Framework” and the “Technology Introduction Process” can help you achieve sustainable WASH services.

Word from the Chair: How do we widen the net?

Transferring the Knowledge: Handpump Training with Erich Baumann and the Austrian Red Cross (Photo: S. Furey, 2012)

If you receive this newsletter, and if you routinely receive the latest RWSN Field Notes and other knowledge products, then you are, like me, one of the privileged few who is reasonably well (or very well) connected to internet and email.  Assuming our workloads allow, we have wonderful opportunities to read and so access the experience and knowledge of water professionals and organisations around the world, and to use or adapt that knowledge to our own circumstances.  But what about those who work in remote areas, with limited travel or conference budgets, and with poor or no electronic connectivity?  Professionals who work for local Governments, local NGOs and CBOs, and the local private sector, who have very limited access to up-to-date experience and knowledge, either in their own country or beyond.

How should RWSN and other similar organisations communicate with and support such important workers?  Is it simply a matter of extending internet connectivity and speed ever more widely?  Or are there other things that we should be doing in the meantime to get better knowledge and ideas into the minds of local workers, so contributing to a greater level of professionalism at the ‘coal-face’?  If you have ideas about this, do please write to me or to the Secretariat.  Should we be producing different kinds of knowledge products, disseminating them in different ways, and helping our fellow workers assimilate and use them better?  Do let us know what you think.

Water is a social problem, not just about health

Water Journalists- Africa's avatarWaterSan Perspective

Water scarcity in some parts of Uganda has led to increased domestic violence in homes.

One of the worst affected is Bushenyi district in the southwestern region.

Wills Bashasha- the Bushenyi district chairperson says that the water shortage in the district had led to many women being beaten by their husbands, while others are allegedly raped as they travel far off places to collect water from shallow wells.

He now wants households with iron-roofed houses to construct water harvesting tanks as a measure to reduce on causes of domestic violence in homes.

Bashasha notes that it’s a shame to find people carrying jerry cans of water collected from far off wetlands and swamps despite the fact that such water could have been tapped during the downpour before flowing off to the wetlands.

He explains that the issue of lack of water in some homes has…

Defender or Prius? When it comes to WASH technologies, are we asking the wrong questions?

The Rope Pump - the Land Rover of rural water supply? (Photo: RWSN/Skat)

In her latest blog post “What’s wrong with a free car?”, Susan Davis of Improve International argues that giving away cars for free would not solve mobility problems for those on low incomes and that likewise, with WASH projects, giving away a capital asset does not help a ‘beneficiary’ if it leaves them with crippling running costs that they can’t afford. In planning WASH services we need to consider lifecycle costs.

There are also parallels in terms of technology choice: do you buy an old Land Rover, which will be unreliable but many things can be fixed by the owner (My neighbour and I changed a head gasket and a cracked cylinder head on my 20-year-old Defender, and I spent many happy – and unhappy – hours tinkering),  or do you buy a Toyota Prius that will be ultra-efficient and reliable, but when it does break will cost and fortune and needs specialist skills and materials.

What should water users in say, Nicaragua or South Sudan, choose for their pump? Would they be better with a handpump that is precision-manufactured out of the very best materials to make it as reliable as possible, or a Rope Pump or an EMAS pump that can be made cheaply from readily available materials, and can be easily fixed by the user if it goes wrong.

It may seem to perverse to compare the two situations where millions everyday around the world do not have access to safe water, let alone a vehicle. But I found Susan’s comparison a helpful one in explaining the value of a topic like lifecycle costing that at first glance can seem intangible and academic.  In the WASHtech project we, along with our project partners IRC, WaterAid, Cranfield, KNUST and Netwas, have embedded the findings of WASHCost from day one so that the assessment of the applicability of new WASH technologies tries to get the whole picture.

What lifecycle costing does is that it shows us that there are better questions to questions to ask than just “which technology is better”.  Instead:  for any given context, which approach to supplying a water service is the most financially sustainable? What are all the costs involved, not just the CapEx and OpEx? If water users and Government can be provided with that information, in a way that is clear and understandable, then they have a fighting chance of getting a system that works, and continues to work.
