In the last 32 years we have invested £12 billion in improvingthe sewage treatment system. During this time we’ve contributed to making rivers healthier than they have ever been before. But we still have further to go and now is the time to take it to the next level.
We are investing £100m a year on our sewage network improving our sewer systems, reducing sewer flooding and pollutions and installing more monitoring capability.
River health in England is measured by the Environment Agency (EA). All waterbodies aim to achieve Good Ecological Status, which means that the river is as close to its natural state as possible.
The EA measure this looking at a range of aspects including:
- the amount and size of fish and other species
- the presence of chemicals like phosphate, ammonia and dissolved oxygen
Water companies, such as Severn Trent, account for 24% of the remaining quality issues in England’s rivers. With other sectors, including agriculture, housing and transport amongst others, accounting for 76% of the reasons for rivers failing to achieve good ecological status.
