Drinking safe water

Even if households have access to safe water (safe water = free from microbiological or chemical contaminants), several obstacles might prevent them from drinking safe water:

  • They prefer to go to the unsafe well because they are used to it, or it is nearer, or the water is cheaper

  • They collect safe water, but their transportation and storage containers or their drinking devices are unsafe

  • They do not use any water disinfection technique

We analyze the psychosocial and contextual drivers of not performing these behaviors and develop interventions focusing on exactly these drivers.
