Risk assessment in municipal wastewater treatment plant

Abstract

Each technical facility is exposed to a risk that will hinder or prevent its proper functioning. Risk assessment is a component of the risk management process in municipal wastewater treatment plants, the purpose of which is to reduce the occurrence of events as well as their resulting effects, which adversely affect the operation of the treatment plant. The authors, having based their work on the identification of risk-related phenomena, estimated the value of risk and determined its acceptability. The result of the work was to obtain a risk matrix – in other words, a risk map with a designated hierarchy. This could then be used as a basis to determine the level of risk that an event triggered. This allows for faster response to risky situations and an optimal selection of remedies.
