A journey down Ampney Brook

How sewage pollution is affecting your rivers and streams

Top

Ampney Brook starts near Cirencester. Like the River Windrush, the water is naturally filtered by limestone, making it very clear.

Ampney Brook is home to a healthy fish and invertebrate population. Freshwater fish, such as trout, flourish in these conditions.

Let's look further downstream

Downstream, there's a mysterious pipe near the sewage pumping station. It runs into Ampney Brook and foam spills out.

We cannot prove a link, but downstream of the sewage pumping station the water gradually
becomes murky.

The water now takes on a different appearance. So does the riverbed and weed, which is coated in algae and sediment. This is a common sign of sewage pollution.

What happens if we keep going downstream?

Anchor 12

Now we come to the sewage works. There's an outfall pipe and more strange foam.

Downstream of the sewage works, we find algae and sediment covering the weeds. This prevents photosynthesis and chokes aquatic plants.

Beneath the surface, the water is cloudy and grey. Some trout appear to be surviving, but these conditions are not conducive to life.

Why does it matter?

Animals

Many species of fish can't spawn in polluted riverbeds. You may not see dead fish, but they'll slowly disappear.

Plants

Plants are choked by sewage pollution. Eventually, they will stop growing -- removing an important habitat for many species.

People

Sewage pollution makes water unsafe for people and their pets. This is happening in rivers across the country.

"We want to pass the river onto the next generation as an asset - not a liability."
