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.
