The efficient removal of thermotolerant coliforms in drinking water is essential for human health. For this reason, the objective of the work carried out was to determine the efficiency of the chlorination process in the elimination of thermotolerant coliforms from the “Santa Rosa” Drinking Water Treatment Plant (PTAP) - Chota. 10 samples of water distributed in the rainy and dry season were carried out for both raw water and treated water. Data analysis was performed using simple samples. Good bacteriological quality was defined: water with adequate free chlorine, absence of total coliforms. To take water samples, the Protocol established by the General Directorate of Environmental Health (DIGESA) of the Ministry of Health was taken into account. The results determined the presence of thermotolerant coliforms in raw water, with variations from 149 NMP / 100mL to 168 NMP / 100 mL respectively; however, the chlorination process managed to eliminate thermotolerant coliforms with an efficiency of 100%. The treated water met the Maximum Permissible Limits (LMP) for water for human consumption.
