Disponibilité et qualité des eaux de boisson consommées dans quelques établissements scolaires de la ville de Yaoundé (Cameroun Disponibilité et qualité des eaux de boisson consommées dans quelques établissements scolaires de la ville de Yaoundé (Cameroun).10363 Availability and quality of drinking water consumed in some schools of Yaoundé (Cameroon) ABSTRACT Objective: Water is an essential resource for life meanwhile million people worldwide still lack access. This study was carried out in 20 public schools of Yaounde in order to assess the effectiveness of investments performed by the Cameroon government in terms of availability, physico-chemical and bacteriological quality of drinking water. Methodology and Results: After field surveys, it appears that schools are provided with two types of drinking water facilities: 85% with tap water from Camwater, 10% with drilling water and 5% are using both facilities. However, water is not available most of the time due to many cuts and limited drinking water facilities in each school. Schools are trying to solve this problem by storing the water collected in containers. It appears from the analysis of water samples that some parameters (pH, Turbidity, Temperature) of stored water do not meet WHO drinking water quality guidelines. More worrying, water samples are contaminated at 95% by fecal coliforms. The deterioration of the water quality is linked to its storage in uncleanliness containers and its manipulation by dirty hands. Because it prevents the contamination of water, treating water techniques are effective in ensuring the microbiological quality of drinking water at the point of consumption. Conclusion and Application of results:This study recommends, the multiplication of drinking water facilities, implementation of water treatment techniques and the promotion of hygiene practices in order to enhance the educational performance of schools learners. Waterborne diseases, in particular diarrhea, are among the principal causes of morbidity and mortality in most developing countries and can contribute to decrease in many ways the growth, cognition, learning ability and finally exacerbate school absenteeism. Contaminated water is one of the main vehicles for the transmission of diseases, which affect youth, the most vulnerable part of the population.
