The Household Water Test Kit is an educational presence/absence test kit, protected by patent office, which detects bacteria of fecal origin in drinking water. 

 It is used in particular in the context of community and household awareness raising operations: possible contamination between an improved water source, serving good quality water, and the point of consumption at household level can be discussed.

 The presence of fecal bacteria in water is a clear indication of contamination from human or animal excrement, which carries a high risk of pathogenic microorganisms causing severe waterborne diseases (e.g. Cholera).

Monitoring fecal bacteria is crucial to ensure safe drinking water and safeguard public health. According to the World Health Organization (WHO) drinking water guidelines, safe water must not contain any fecal indicator bacteria. (Reference: WHO Guidelines for Drinking-water Quality, Fourth Edition, 2011, page 36)”

The Kit has numerous advantages in its use in rural areas and with respect to the objective of education and sustainable behavior change. 

It is very simple to use and contains clear how-to-use illustrations which help illiterate people to understand the testing process and to read the results.

The household kit follows a simple multi-barrier approach proposed by the World Health Organization for households that are not directly connected to a water supply network: (i) improved source; (ii) household treatment; (iii) safe storage after treatment.
