Objective:

To analyze the association between the infrastructure of rural supply systems of Boyacá and the quality of water for human consumption distributed during 2016.

Materials and methods:

Retrospective descriptive analysis of secondary data of independent variables in infrastructure of 288 rural supply systems, using descriptive, bivariate and multivariate statistics in relation to the dependent variable of water quality for human consumption named CAT.

Results:

not having a treatment system reduces in 0.2 (95% CI 0.05 - 0.72) the chances of complying with CAT compared to having a treatment. Likewise, if an aqueduct controls the efficiency of the purification processes, they increase in 4.2 (95% CI 1.16 - 15.25) chances of not exceeding CAT, in comparison with systems that do not perform this operational activity.

Conclusion:

The unsafe water supply in the rural areas of Boyacá is associated with the lack of potable water infrastructure and the control of the efficiency of the purification units as a routine operational activity. These variables are related to the presence of Escherichia coli and coliforms in the drinking water of these communities.
