Wastewater treatment

We help companies achieve and sustain the highest standards across the entire industrial water cycle. SUEZ research and wastewater expertise are also making our customers’ processes more sustainable.

Failure at any stage of the effluent management process can compromise operational efficiency, site safety and the local environment. Breach of discharge consents may lead to prosecution or even plant closure.


With extensive experience in industrial water management, SUEZ provides a comprehensive range of services – troubleshooting, consultancy, treatment, design, construction, operations, maintenance and optimisation – to businesses in all sectors.


We help companies, whatever their scale, to achieve and sustain the highest standards across the entire industrial water cycle – even returning water to the environment cleaner than when it was extracted.


With our help, you can:

  • Control your site’s effluent discharge and be assured of compliance with standards and regulations.
  • Employ the latest, most efficient aerobic and anaerobic biological treatment technology.
  • Ensure your systems are running to their optimal level.
