The study of water quality has been evaluated by many national and international studies, as it is essential and vital for water intended for human consumption to have the necessary characteristics to ensure its risk-free consumption. The WHO, through its guidelines for drinking water quality, emphasizes prevention and sustainable access to drinking water for economic development. Locally, the General Directorate of Environmental Health (DIGESA) aligns with this, especially with its regulatory framework DS-031-2010-SA. The objective of this study was to evaluate the mandatory control parameters for the quality of water for human consumption in the reservoirs of the Rio Seco – Cieneguilla rural town center, from March to October 2019. The methodology used was a descriptive, cross-sectional, and non-experimental study with quantitative microbiological and physical analysis based on current regulations. The population consisted of 46 properties, and quality was evaluated according to the following parameters: Determination of total coliforms and Escherichia coli, and determination of physical parameters (pH, residual chlorine, turbidity, and color). An evaluation through surveys showed that 67.4% of properties did not continuously clean their reservoir and 28.3% did not purify the water they consumed. This improved after training was provided, with a predisposition to improve sanitary measures, resulting in 70% purifying their water and 80% continuously cleaning their reservoirs. Results: 97.8% (45 samples) tested positive for total coliforms, and 34.8% (16 samples) tested positive for Escherichia coli. These results were compared with the permissible parameters according to current drinking water quality regulations. Conclusion: The water consumed by the population does not comply with the mandatory microbiological parameters of the DS N° 031-2010 SA, DIGESA regulation.
