Water can be and often is, polluted, resulting in the spread of many diseases: parasites, amoebic dysentry, Weil’s disease or leptospirosis (know locally as Rat Fever), cholera and typhoid are common. Even water from bore wells which is usually unpolluted can easily become so during transit to and storage in the house. Lack of water or the difficulty of accessing water can often result in lack of hygiene especially by younger children. It is hard to wash your hands if you don’t have reasonably easy access to water. Clean water is needed for drinking and cooking, for the washing of bodies and of utensils. Water is needed to wash clothes, wash houses, and to make crops grow. A lack in any of these areas will result in ill health. Boiling water to make it safe to drink, requires the use of fuel, which is needed for cooking. The gathering of fuel, usually scrap wood, also takes time.
