Trade Effluent

During the current Covid-19 outbreak, we are committed to supporting our business customers. If you want to discharge any perishable product, you need to contact us before discharging it to our sewer network.

Any illegal discharge can not only have severe effects on the environment, but is also an illegal (criminal) act under the Water Industry Act 1991. We will enforce our regulatory duties when it comes to monitoring our network for illegal effluent that damages the environment, and this may include prosecution for environmental offences.

If you have any queries relating to the disposal of products or other trade effluent please don’t hesitate to contact us at Trade.Effluent@dwrcymru.com.

If your business plans to discharge trade effluent into any public foul sewer within our supply area, you must get our permission before any discharges take place.

This is a legal requirement under the Water Industry Act 1991. Trade effluent can be best described as anything other than domestic sewage (toilet, bath or sink waste) or uncontaminated surface water and roof drainage (rainwater).
