This consultation has now closed. NRW will use the feedback from the public consultation to inform our new charging schemes, which we intend to implement from 1 April 2023, subject to Ministerial approval.
If your discharge of effluent can’t be registered with us as exempt, you will need an Environmental Permit. These discharges can include:
- Discharges of trade effluent to ground or to surface water
- Discharges of mixed effluent (trade and sewage) to ground or to surface water
- Discharges to groundwater via a borehole, well or other deep structure.
- Discharges to water from a heat exchanger into surface water
