It's humorous that most of the answers provided meet neither criteria of being very simple and non-imported.
Anthony - I suggest you look into constructing a roughing filter. Here is a link to a good paper that discusses using them for drinking water treatment, but there is much more information readily available via Google.
They are a very simple technology that is well-suited to implementation in developing countries.

i agree with Daniel. A simple sand filter with some anthracite will take care of most suspended solids. Just make sure you have a back wash system for this. This is cheap and cost effective treatment. if this doesn't accomplish your goal on turbidity you just add a polymer dosing system to this to bring NTU's down even further. Tim Shrum

That was my first reply. No other exotic technology is needed at this stage, unless more water details are knowing

Polymer dosing is simple in theory, but complex in practice. The wrong polymer can stabilize the suspension and make the problem worse. Extensive jar testing is mandatory before proceeding with full-scale. Also, you need high-quality make-up water that I'm guessing might not be available. It's probably not economically feasible in this case, either. Dry floc systems run at least $100k, plus the ongoing cost of the reagent. Let's not even mention the logistics of getting any of this stuff in Haiti.
That said, it is still a much better suggestion than microfiltration or ultrafiltration...in Haiti.
