Water watchdogs move to prevent pollution of River Dee

Businesses on an industrial estate in Corwen have received important guidance as part of a campaign aimed at protecting the nearby watercourses, including the River Dee, from pollution.

On Wednesday August 14, Natural Resources Wales (NRW) officers visited various units on the Ty’n y Llidiart Industrial Estate. 

This is the latest industrial estate visit across North East Wales designed to help businesses identify any pollution risks associated with their operations.

During the visits, officers discussed possible pollution prevention measures and provided advice on any necessary consents and environmental permitting requirements. A letter drop was also carried out at a nearby residential area to raise awareness of potential misconnections to the surface water line.

The nearby waterways, such as the Nant Fawr, have faced several pollution incidents over the years. 

NRW says these incidents are often caused by accidental releases of harmful substances from nearby industrial sites or incorrect connections to the surface water drainage system.

And they stress it is crucial that pollution risks to the surrounding streams are minimised given their connections to the River Dee. 

This vital watercourse is recognised as a Site of Special Scientific Interest (SSSI) thanks to its diverse wildlife, including species like lamprey, Atlantic salmon, and European eel.

The Dee is also an important source of drinking water. It was designated as a Water Protection Zone under the Water Resources Act, 1991, meaning consent is required where certain substances are used or stored at specific sites anywhere within the designated area, which includes Ty’n y Llidiart Industrial Estate.

Rhys Ellis, NRW Environment Team Leader for Denbighshire, said: “Pollution incidents can occur frequently due to spills, accidents, or even vandalism. These incidents not only endanger human health but also have a devastating impact on local wildlife and water quality.

“By proactively engaging with businesses at Ty’n y Llidiart Industrial Estate, we aim to ensure they have the necessary measures in place to prevent such pollution. This initiative will help raise awareness about the risks of pollution from industrial estates and safeguard the river Dee and its surrounding habitats.”
