Thorough, accurate flow inspections

An approved and impartial provider of MCERTS inspections for water discharge monitoring systems.

Trade Customers

Your partner in ensuring compliance

If you are trading in industry and have been served a consent to discharge trade effluent then you will need to meet certain requirements regarding your monitoring of waste water. These requirements may include MCERTS inspections of your monitoring solutions, processes and systems.


Our certified MCERTS inspectors can carry out site inspections of your flow measurement and sampling systems and issue conformance reports or recommendations based on their findings.


Depending on the results, you will be issued with an MCERTS certificate, valid for 5 years, to confirm your compliance.

MCERTS Certification

Our inspectors will visit your site to carry out their inspection before producing a report. If your site passes then you will be issued with a 5-year certificate by the CSA Group. If your site does not pass, then your report will include details of recommended actions to take. Once remedial work has been carried out, then our inspectors will carry out a second inspection of your site.
