[HCG25-01] Report for household management of drinking water in a rural area of Cambodia
★Invited Papers
Keywords:Cambodia, Drinking water, Coliforms
BACKGROUND: Cambodia, one of the developing countries, is facing issues in safe drinking water security, especially in rural areas.
OBJECTIVE: To clarify the management process of drinking water in households in rural Cambodia
Methods: Observations and interviews on the process of obtaining drinking water from collection to consumption and an incubation experiment using Compact Dry.
RESULTS: We examined 13 households in five villages in one Kampot province. The original water sources were wells and rainwater. The process from source to drinking water was organised into seven stages, which varied from household to household. Coliforms were detected in many of the water sources. Boiling and filter filtration during the process up to the drinking stage ensured that the water was free of coliforms. However, coliforms were detected in most of storage and drinking materials subsequently used, and there was only one case of drinking water free of coliforms at the drinking stage. Water from moated wells at a depth of about 30 m had no or mild coliforms contamination. But there were no cases of direct use as drinking water because of its odour or poor taste.
DISCUSSION: Even if the methods used to properly remove coliforms - boiling and filter filtration - were used, the water was contaminated with coliforms at the time of drinking due to subsequent processes. The risk of diarrhoea occurring due to drinking water is considered to be high. Water from moated wells with relatively low coliform contamination was not preferred as drinking water, while rainwater with a large number of coliforms was preferred. It is considered that preference, as well as safety, is an important factor in the choice of drinking water.
CONCLUSION: There are various challenges that need to be solved to ensure safe drinking water in rural areas. It is necessary to share these issues with the population, the users, and consider how to ensure safe drinking water.
