Application for trade effluent consent

You need consent to discharge trade effluent

Trade effluent consent is a vital part of wider legislation which protects the environment. It is illegal to discharge trade effluent without consent and doing so carries the risk of prosecution and fines. A trade effluent consent does not permit discharge of potentially hazardous chemicals to the sewer – businesses must ensure waste of this nature is disposed of responsibly via a specialist waste contractor.

Why you need consent for trade effluent

Unlike domestic sewerage, trade effluent is highly variable in terms of volume and contamination strength. It is therefore necessary to regulate this wastewater to ensure the sewerage network can adequately handle and treat the waste. This is to protect the health and safety of staff and to protect the environment. 

To regulate trade effluent, businesses are provided with a licence, or discharge consent. The licence defines the nature of the allowable discharge and establishes any restrictions. Samples of the trade effluent discharge are taken regularly to ensure the customer is complying with the terms of their consent. 

It is a criminal offence to discharge trade effluent waste without a consent.

Please note this is a chargeable process, with fees imposed by the respective Wholesaler for the application.

Please be aware that once consent is granted there may be a further charge from the Wholesaler relating to the actual discharge. This charge will not be quantifiable until raised by the Wholesaler.

You should not begin discharging trade effluent until you have received a valid discharge licence; It is a criminal offence under the Water Industry Act 1991 to make a trade effluent discharge to the public sewer without the permission of the appropriate sewerage undertaker.

Please be aware, new applications can take up to two months for wholesalers to grant.
