Rick and Kathy Adams were here from 2:45 to 5:45 today. We learned a bunch about Haiti and their motivations, details of the trip, a pump system on their UF water filter, etc.
The general wisdom among agencies that help poor countries is to make hardware out of the most local and easy to fix materials as possible. In Rick's experience, they don't even fix a broken chain or rod. Even the simple manual pumps often fail and don't get fixed.
I'm thinking it might work better to use reliable high tech devices and have a trained local person who can replace modules. For example: Replace the manual pump that seems like too much work and fails a lot with a solar panel and a standard submersible well pump.
They paid $15,000 for just the hardware for that manual pump and a four stage UF filter. With the electric pump it seems that about $5k could do it with the advantage that it takes little manual labor and it could be submersed in a well or river.
