Environment Agency
The Environment Agency set up the monitoring certification scheme (MCERTS) to provide guidance on the standards you must meet to monitor emissions that affect the environment.
This standard applies if you have a permit under the environmental permitting regulations and that permit says you must:
- monitor liquid flow (for example, sewage or trade effluent)
- collect and record the results of your monitoring
This standard specifies the minimum requirements for self-monitoring flow where operators have installed meters to conform to the Environment Agencys permit requirements.
Natural Resources Wales permits may also specify that flow monitoring systems are certified against this standard.
