The sewage scandal
The sewage scandal is – rightly – an election issue: the rivers and lakes of our great National Park should be at the top of the clean up list
The water bodies in our National Parks are under threat like never before, we explain the issues facing waterways and our work to end water pollution
The waterways of the National Parks are some of the most iconic. The Broads is the most biodiverse wetland in the UK, the mountains of Eryri and the Lake District include spectacular glacial lakes and the South Downs spring a significant proportion of the world’s chalk streams. The uplands of Dartmoor and Exmoor include wet bogs and sensitive headwaters of rivers and the waterfalls of Bannau Brycheiniog are world renowned.
Every year, millions of people explore these rivers, pools, lakes and wetlands, whether that’s navigating their waterways by boat or taking the plunge and wild swimming. These waters are the lifeblood of the National Parks, but they’re under threat.
Did you know? Not a single water body in an English National Park is in good overall health.
Healthy water bodies deliver a range of benefits: in addition to supporting biodiversity, they contribute to improved drinking water quality, support natural flood management, enhance climate mitigation, and are, of course, much valued by people as places for recreation and relaxation. The condition of water bodies in National Parks has implications far beyond the boundaries of those Parks with links between the quality of freshwater and the health of our oceans.
Our Protected Landscapes are under threat like never before from sewage discharges. Our outdated and underinvested infrastructure can’t cope with an increasing population, urbanisation, and climate change. Water companies are legally allowed to discharge untreated wastewater through sewer overflows during periods of heavy rain, but there are countless examples of this happening routinely.
Sewage in our lakes and rivers is not only unpleasant but it’s also dangerous. People who swim and want to enjoy the water for recreational activities can become seriously unwell from encountering polluted water. Increased phosphorus levels from sewage can be fatal for nature in and out of the water, causing events such as fish die-offs.
Water bodies can be contaminated in many ways. Nutrient and sediment contamination results from agricultural activities, such as the spreading of fertilizers and manures onto fields, which are then washed into nearby rivers and lakes by rainfall. Toxic chemicals can enter from a variety of sources, from pesticides use in agriculture to freshly applied flea and tic treatments on swimming dogs.
Even in the most pristine rivers and lakes in England’s National Parks, traces of toxic chemicals including mercury and other priority hazardous substances are found. Because of these toxic chemicals, which can remain in the ecosystem for decades, not a single water body in an English National Park is in good overall health.
It has been calculated that drier summers could result in some rivers having up to 80% less water in summertime by 2050, increasing the concentration of pollutants and the impact of water being removed for other purposes. Wetter winters and more frequent intense rainfall result in increased flooding and more pollutants being washed off fields and roads into nearby water bodies.
At Campaign for National Parks we’ve been fighting for new powers for National Parks so that higher standards are set by water regulators to keep our incredible waterways clean.
We’re also ensuring that public bodies including water companies, follow the law to take far greater action for Protected Landscapes.
We also support organisations and campaigns who lobby water companies directly to stop sewage spills into our lakes, rivers and oceans.
