Helping businesses protect the River Alyn from pollution

Businesses based at Llay Industrial Estate have been supported to help stop pollution from reaching the nearby River Alyn.

On Thursday 6 November, officers from Natural Resources Wales (NRW) visited several units across the estate to offer practical advice on how to reduce pollution risks and improve environmental practices.

The aim of the visits was to help businesses spot potential pollution hazards and understand what steps they can take to prevent incidents. Officers also provided guidance on environmental permits where needed.

Singrett Brook runs through the estate and eventually flows into the River Alyn – a key tributary of the River Dee. Unfortunately, the brook has been affected by repeated pollution incidents, often caused by accidental spills or incorrect drainage connections from nearby industrial sites.

The River Dee is a designated Site of Special Scientific Interest (SSSI) and a Special Area of Conservation (SAC), recognised for its rich biodiversity including species such as salmon, bullhead, lamprey, otters, and a variety of plants and invertebrates.

It’s also a vital source of drinking water. Because of this, the area around the river – including Llay Industrial Estate – is part of a Water Protection Zone under the Water Resources Act 1991. This means that certain substances must be carefully managed and stored, and may require consent.

Elizabeth Felton, NRW’s Environment Team Leader for Wrexham, said:

“Pollution from industrial estates can happen all too easily – whether through spills, accidents, or even vandalism. These incidents can harm wildlife and pose risks to people’s health.

“By visiting businesses on the estate, we’re helping them take practical steps to prevent pollution and protect the local environment.

“We want to raise awareness of the impact pollution can have on rivers like the Alyn and support businesses to do their part in keeping our water clean and safe.”
