Trade effluent is a liquid waste, discharged into our sewers from a business or industrial process. We need to control discharges entering the public sewer system so that it can be safely handled and treated before it's returned to the environment. As a business, charity or public sector organisation your primary point of contact should be your retailer.
As your wholesaler, we’re committed to providing a quality service across your network. If you're planning to discharge trade effluent into our network, you’ll need to apply for consent - you can find information on how to do that below.
Consent applications, variations and terminations
Your retailer is set up to order services on your behalf, and they will also be able to apply for your consent to discharge. We recommend that you work with your retailer to apply for a consent or a variation to existing consent conditions or a consent termination, this User Guide describes how to do that in detail. In the case you'd like to apply directly to us, please use the G/02 service request form for a permanent consent or the G/03 service request form for a temporary consent. As charges will be made to you through your retailer, please consult them for all information concerning this.
We’re required by law to share a public register of all our authorised trade effluent consents, and you can use our search tool to view it:
Monitoring and sampling discharges
Once a trade effluent consent is issued, we may carry out sampling and analysis to determine the applicable charging structure. Under the terms of a trade effluent consent, you may be required to pay for the monitoring and analysis we carry out. For more information about the charges, please contact your retailer. Alternatively, you may be able to arrange for your own trade effluent billing samples to be collected. Please work with your retailer to follow the correct process.
From time to time, we may visit your site to monitor your compliance with the consent conditions. As part of this process, we may need to take samples to assess the effluent and any health and safety risks. If any samples taken aren’t compliant with the consent, charges may be made to you through your retailer.
