Its main activities require considerable volumes of water at the same time, should not be dismissed on the ground or collecting networks, they could generate risks to the environment. Thus, this article aims to evaluate the frequency and risk of the activities of the concrete plant on the use of water. In addition, monitor the quality of water treatment system for pH and turbidity. To this end, we applied the method of the Activity Risk Assessment together with in situ observations to better represent the actions of a conventional production day. The survey was conducted by six random days for three consecutive weeks. To evaluate the quality of wastewater pH and turbidity, always on the last day of production of the plant were monitored, representing the worst case. The results showed that washing of trucks is the activity that presents the greatest risk to the environment, because it happens more often within the space of production. The current system cannot remove turbidity for allocation of water to the reuse while maintaining the pH above 12.porAcesso AbertoUsinas de concretoAvaliação de riscoQualidade da águaresiduáriaConcrete plantsRisk assessmentQuality of wastewaterArtigo10.521/reec.V9i4.32759
