Dear Patrick

If the government (DINEPA) prefer India Mark, then go for that - if the well is deep enough. Preferably the India Mark III which is easier to maintain for the reasons pointed out by Les. It is slightly more expensive because rising main diameter is wider so that the foot valve assembly can be lifted out without having to pull out the whole rising main. I notice that they put it in their guidance manual: https://dinepa.gouv.ht/referentieltechnique/doc/1-aep/1.2.1%20DIT4%20Pompes%20a%20motricite%20humaine.pdf

For sourcing, talk to DINEPA and they should know who the main stockists/importers are.

A couple of alternatives, if the wells are only going to be used by a few families (rather than 200-400 people) are: A rope pump: https://rural-water-supply.net/en/implementation/public-domain-handpumps/rope-pump An EMAS pump: https://rural-water-supply.net/en/implementation/public-domain-handpumps/emas-flexi-pump

Hope that helps
