As per your request regarding rope pumps see below ... these are links to the files in our TSU DropBox folder but available to everyone if you click these links. I have included other in this email as well for their interest.
Note that the Mozambique version was developed from the detailed design from Madagascar. We decided not to do detailed designs for Mozambique, but just the manufacturing guidelines. The one thing that I line about the Burkina model is the complete cover which solves some of the problems we had with the Moz & Mad versions with dripping water. The Burkina model cover is also easier to make.
Also note that all of these are designed for Communal water points. The pump can be simplified for household situations and for irrigation purposes.
You can also download the very detailed manuals for the Nicaraguan model here: http://www.ropepump.com/
WOT developed a rope and washer pump that was suitable for greater depths. If the enclosed pump is unsuitable then you can contact WOT at the following address.

Website: http://www.wot.utwente.nl A non-profit organisation working in the field of small scale sustainable energy, based at the University of Twente.
Practica Foundation has also done some work in this area.
The Practica Foundation aims to facilitate research, development and commercial application of technology in the field of water and energy in developing countries. The choice for water and energy-related technology comes from an assessment that these are often prime movers in rural livelihoods and the conviction that there is still considerable scope to reduce cost and improve Their design of rope and washer pumps can pump to a depth of up to 35m Yield 30 litres per minute at 10m 20 litres per minute at 20m 10 litres per minute at 30m Costs 70 – 150 Euro, depending on depth, local material and labour costs They seem to have links with another organisation working in Tanzania on rope and washer pumps called The GAIA-Movement Maison de l’Environnement II, Chemin de Balexert 9, CH-1219 Châtelaine, Switzerland Tel: +41 22 917 8783 Fax: +41 22 797 1768 Mobile: +41 76 421 0154 Email: email@example.com The GAIA-Movement developed the TaZaMo project together with the Dutch NGO “Connect International”. TAnzania, ZAmbia, and Mozambique (sounds like the Dutch word for “together”) is funded by the Dutch Government. The project installs rope pumps in Tanzania, Zambia and Mozambique.
TaZaMo is implemented by SHIPO in Southern Highlands, Tanzania, DAPP in 4 Zambian Districts, and ADPP in Itoculo, Mozambique.
The first wind-rope pump in Africa was built at Chimoio. Henk Holtslag, associate of the Dutch Practica Foundation, has developed the model in Nicaragua, where 350 farmers now use them to irrigate 1-2 ha each. The windmill can - after training - be built from locally available materials in a metal workshop with basic equipment.
Also in Tanzania, Brian Polkinghorne has been working on rope pumps for some years.

Brian built many of Robert Lambert's Rope and Washer Pumps over the years And has also worked on a deep wells (35 to 46 feet). Translated the book into Kiswahili.
