Due to their essential role in monitoring and managing industrial and environmental discharges, self-monitoring systems are subject to regulations that impose various obligations on companies and local authorities. 

This equipment must undergo regular technical inspections of industrial discharges, to ensure the accuracy of the data collected and environmental compliance with existing requirements. 

CTC can help you verify and audit your self-monitoring systems to ensure that the monitoring of your facilities is reliable and secure. Our qualified team is certified by the Rhone Mediterranean Corsica (RMC) Water Agency and works with local authorities, farmers and manufacturers.

Thanks to our expertise in on-site measurement and our specialised equipment, we can guide you through each stage, from the initial audit onwards, offering customised recommendations.

How our on-site measurements work 

Our interventions take place in several stages to guarantee the reliability of the self-monitoring systems: 

• On-site inspection: verification of the facility, accessibility and general operating conditions. 
• Metrological check: comparative measurement of on-site equipment (flowmeters, sample takers) in accordance with standardised self-monitoring audit methods. 
• Parameter analysis: verification of sampled volumes, temperature of refrigerated chambers and sample repeatability. 
• Verification of procedures: audit of procedures and self-monitoring manual, including examination of sampling and maintenance forms. 
• Summary and recommendations: delivery of a detailed audit report meeting the RMC Water Agency’s requirements.
