Thanks, excellent plans. Since we have a staff welder, this is not going to be hard (for me that is! :lol:)

I like the idea of the rope/paternoster pump.

Some alternatives that might be worth investigating:

A DIY Piston Pump - Videos on "EMAS" and "Baptist" technologies for water supply in rural communities in developing countries. - includes full set of videos on how to make it - probably needs adapting to your situation, but it should be easy to drive from a large turning wheel - there are some nice PVC piping techniques in these videos.

What about using a car water pump (belt driven) or perhaps some direct drive washing machine water pumps? Belt drive from a large turning wheel should easy.


I think a big advantage of the rope pump is that it looks like it is very simple and probably has no problem with dirty water. Washing machine pumps are generally only good for about a meter. I probably will need 2 meters. The same is true for a car water pump.

The EMAS pump looks interesting as well - but the rope appeals more from a coolness factor. :D

Hey, if you do make one, any documentation, feedback or local adaptations you make would be really appreciated by RDIC - they're trying to make their technology available and useful to as many people as possible :cheers:

I love the use of a bike tyre for the rope guide :geek:
