Again, thanks for your responses:You_Rock_.
B R when you mention the stainless steel hand pump is that any thing like you see on those water for Africa adverts?
Also, on a side note are the concrete water towers simply a giant version of a domestic borehole system. Being a bit ignorant, I always assumed they pummped water from a reservior up into the cistern, does it actually come out of the ground directly below the tower?

He means something like one of these
You need to always keep a pail of water near to prime it before pumping.
