Contextualization: Colombian rural areas have a deficit in the coverage of safe water supply service. In addition, the treatment systems already implemented are not efficient enough in the removal of pathogens.

Research gap: The waters used for consumption are not treated properly, added to the poor coverage of its supply, and despite the fact that the population carries out the water treatment on its own, it is not guaranteed that it is in optimal conditions for its consumption.

Purpose: The objective of this investigation was to determine the removal efficiency of an unconventional household system for the supply of safe water in the San Fernando District – Municipality of Pasto, Colombia.

Methodology: Three phases were developed. The first phase was the diagnosis of the study zone, which included a risk map, characterization of the supply source, physical-spatial, socioeconomic and cultural characterization, selection of the population under study and formulation of indicators; the second phase defined the technology to be implemented through the multicriteria analysis and hierarchical analysis process with 6 experts, where the participatory transfer strategy for hygiene and sanitation was also designed and implemented, complemented with the teaching-learning strategy; the third phase  determined the efficiency of the safe water supply system implemented.

Results and conclusions: By mean of 3 monitoring samples and the comparison with the raw water samples obtained in the characterization, it was determined that the treatment system was 99% efficient in the turbidity removal, total coliforms and fecal coliforms, which guarantees the consumption of safe water in this population.

On the other hand, it is important to consider that the success of unconventional technologies is linked to the social transfer that is applied throughout their implementation; the appropriation that the community gives to the system is vital for its sustainability over time and for the follow-up process developed by the social leaders of the area.
