Statement on environmental pollution incident in the upper Beaulieu River

Hampshire & Isle of Wight Wildlife Trust is deeply concerned by reports of a major pollution incident affecting the upper Beaulieu River on 16 September 2026, following the failure of a water main near Lyndhurst.

Early evidence suggests that significant volumes of chlorinated water entered the river over an extended period, at a time when river flows were already exceptionally low following prolonged dry weather. The impact may also have been compounded by water flowing along the road before reaching the river, increasing the likelihood of road and traffic run-off, including oils and microplastics, being washed into the river. 

While the full environmental impact is still being assessed, incidents like this highlight how vulnerable our rivers have become to failing infrastructure. Whether pollution comes from sewage overflows, leaking pipes or other failures in the water system, the result is the same: damage to the health of our rivers and the wildlife that depends upon them.

Hampshire and the Isle of Wight's rivers should not be expected to absorb the consequences of an ageing and under-invested water network. The Beaulieu River is one of the jewels of the New Forest, supporting internationally important wildlife and providing benefits for local communities and visitors alike.

This latest incident reinforces why we need urgent action to fix water. We need greater investment in resilient infrastructure, faster responses when incidents occur, greater transparency with communities and regulators, and a long-term commitment to restoring the health of our rivers.

People are rightly frustrated by the steady stream of pollution incidents affecting our waterways. Rivers should be places where wildlife thrives, not where infrastructure failures become routine. It is time to fix water.

Debbie Tann MBE, Chief Executive at Hampshire & Isle of Wight Wildlife Trust, said: 'The details emerging from the Beaulieu River are deeply concerning. While investigations are ongoing, this incident appears to be yet another example of river ecosystems bearing the cost of failing water infrastructure. Whether it's sewage spills, burst mains or chronic pollution, the public sees the same outcome: damaged rivers and declining wildlife.

The Beaulieu is a precious New Forest river, and we need a water system that protects it. That's why we're calling for urgent action to fix water, through better infrastructure, stronger accountability and investment that puts healthy rivers at the heart of decision-making.'" 

"This isn't just one pollution incident. It's another symptom of a water system that is failing our rivers. If we're serious about restoring nature, we need to fix water."
