%X Santa Catarina State has encouraged the use of cisterns as a technology to offer water in quantity and quality to livestock. The region is characterized by severe droughts in the summer months. The aims of the study were: to monitor physical, chemical and microbiological rain water quality parameters of a cistern; to evaluate if water had quality for pigs and beef cattle water consumption. Concentrations of nitrate, nitrite and ammonia were in accordance with the standards for animal consumption. E. coli was present in some samples. The rainfall and speed of wind influenced the concentrations of nitrogen. Investigations of the relations between these environmental parameters and water quality must be conducted to avoid agricultural and livestock emission sources to have a negative impact on water quality. The water stored in the cistern showed satisfactory quality for use of pigs and beef cattle drinking. This gives support to the utilization of this technology to improve the water use efficiency for livestock.
