Apply for a discharge licence
If you release an effluent (other than domestic wastewater or stormwater) to waters or a sewer, you are required to have the appropriate discharge licence in place. Discharge (trade effluent) licences ensure that discharge is treated and controlled in a manner that protects the receiving environment. The below outlines the various types of licences available for trade effluent discharges however if you are unsure which one you require, please call Water Pollution Control and a site visit can be arranged.
Discharge to Waters – Section 4 Licenses
Discharge licences are issued under Section 4 of the Local Government (Water Pollution) Act 1977, as amended in 1990, in respect of the discharge of trade effluent to surface water or groundwater. Licences set conditions so the discharge is treated and controlled in a manner that protects the receiving environment.
The discharge of trade effluent to waters without a licence is an offence under the Act. Failure to comply with the terms and conditions of a Discharge Licence is an offence under the Local Government (Water Pollution) Act 1977, as amended.

Discharge licences in respect of the discharge of trade effluent to sewer are issued under Section 16 of the Local Government (Water Pollution) Act 1977, as amended.
