The obvious sign of sewage pollution of a stream or river is the presence of sewage solids in the water, but there may also other indications. These include:
Pollution can kill fish and other aquatic life, cause a risk to human health, and also affect biodiversity, amenity value, and the use of water and land for agricultural purposes.
Flushing away rubbish down the toilet can cause blockages in sewerage pipes, sometimes leading to the flooding of homes and pollution of the environment. Our Let's Stop the Block campaign highlights the things that are flushed away to cause problems – and which should be disposed of properly.
Fat, oil and grease (FOG) poured down kitchen sinks and drains can build up in sewers and cause blockages and flooding. To help avoid this, please dispose of them correctly. Click here to see our advice.
