Eau potable

Définition
L'eau potable de base est définie comme une source d'eau potable fonctionnelle améliorée sur ou à proximité des locaux et des points d'eau accessibles à tous les utilisateurs pendant les heures de classe. Une source d'eau potable améliorée est un point de distribution d'eau qui, par la nature de sa conception, protège l'eau de la contamination externe, en particulier d'origine fécale. Des exemples d'installations d'eau potable améliorées comprennent l'eau courante, les puits protégés, les puits tubulaires et les forages, les sources protégées et l'eau de pluie, l'eau en bouteille achetée et les camions-citernes. Les sources d'eau non améliorées comprennent les puits et les sources non protégés et les eaux de surface (par exemple les rivières, les lacs).

Basic drinking water

Definition
Basic drinking water is defined as a functional improved drinking water source on or near the premises and water points accessible to all users during school hours. An improved drinking water source is a water delivery point that by the nature of its design protects the water from external contamination, particularly of fecal origin. Examples of improved drinking water facilities include piped water, protected wells, tubewells and boreholes, protected springs and rainwater, purchased bottled water and tanker-trucks. Unimproved water sources include unprotected wells and springs and surface water (e.g. rivers, lakes).
