If your business needs to discharge waste liquid to public sewer as part of its process then you may need a trade effluent consent.

A trade effluent consent gives you permission to discharge waste liquid with agreed limits on volume and other characteristics. It's important that you have one so that you won't be caught out by environmental legislation.

To apply for a consent or to make a change to an exsiting one, you'll need to fill out our trade effluent consent form.
