Microbial Control for Wastewater Reuse


Water resources worldwide are increasingly coming under pressure, leading to water scarcity and a deterioration in water quality. In particular, climate change, unpredictable weather patterns and drought are contributing significantly to the strain on the availability of freshwater, arising from urban development and agriculture.

The ability to respond to these pressures can be improved by wider reuse of treated wastewater, limiting extraction from surface water bodies and groundwater bodies, reducing the impact of discharge of treated wastewater into water bodies, and promoting water savings through multiple uses for urban wastewater, while ensuring a high level of environmental protection.

The European Parliament enacted regulation 2020/741 that defines the necessary quality controls and quality requirements for the reuse of urban wastewater, primarily for agriculture.

The requirements towards microbial controls are based on a risk assessment from the perspective of the downstream use of water. Required tests always include a quantitative detection of E. coli and, if a possibility of aerosol formation exists, the quantitative detection of Legionella.
