How to purify muddy water for potable use

In the Foster Home that we support in Ghana, the water from 60 m deep bore well can no longer be used for drinking due to a mud contamination. The water quality (specifications) is still good, but the mud colors the water brown and negatively impacts the taste. The well water is pumped via a PVCpipe to 4 reservoirs (plastic containers), filtered, and then distributed to approx 100 users. The question is what filtration/purification system can we use to best alleviate these negative effects and where should the filters be installed? Can we add something in bore well itself to get better water? Please note that we are situated in a rural area, with limited access technical support and spare parts. Thank you for your help.
