Information sources related to Malawi

I am an experienced UK civil engineer about to visit South West Malawi for the first time and am looking for sources of info on water sources (wells etc.) and sanitation provision which may be useful. My hosts have just informed me that they are looking at "drilling" a borehole so any advice on pitfalls to avoid or "must do" would be really helpful.

A lot will depend on what part of the country. I taught a national crew on hand pump repair in the north a few years ago, Embangweni area. Most villages in that area had at least 1 or 2 machine drilled wells with Afri-Dev hand pumps, so water table there was typically within 30 meters of surface. (I've probably got records somewhere, this is quick off top of memory). There were also a number of hand turned "Elephant" pumps on larger hand dug type wells (~1.5 M dia.) and a numbers of Malawi made MkIV pumps (direct action with PVC cylinder parts and welded G.I pipe parts aboveground). Hospital there used simple gravity powered system with elevated poly tanks on brick cruciform stands about 6 M tall.

If you provide more details of the area of interest, I'm sure others will have details for that area.

Thankyou, Larry. I shall be visiting the area of Mchinji down in the South West, near the Zambian border.
