Water treatment
Clean water is essential for hygiene, for consumption and for feeding programmes (for mixing with powdered therapeutic milk or porridge), as well as for preventing the spread of water-borne disease. As such, MSF water engineers and volunteers must create a source of clean water. This is usually achieved by modifying an existing water well, by digging a new well and/or starting a water treatment project to obtain clean water for a population. Water treatment in these situations may consist of storage sedimentation, filtration and/or chlorination depending on available resources.
