Monitoring Discharges to Water & Sewerage

If you discharge effluent to a river, small watercourse or the sea, and if effluent flow monitoring is a requirement of your permit, you must monitor the volume of effluent you discharge.

This applies to large sewage treatment works, and PPC/EPR installations with effluent flow monitoring specified in their permits. This will include discharges to public sewer.

You are required to have your site inspected by an inspector under the MCERTS Self Monitoring of Effluent Flow Scheme. If your flow monitoring arrangements meet our requirements and you demonstrate satisfactory maintenance procedures you can apply to Sira Certification Service for an MCERTS site conformity inspection certificate.
