Updated: Report and summary graphic added: Environmental performance of the water and sewerage companies in 2017.
There are 9 water and sewerage companies that operate wholly or mainly in England, providing clean (drinking) water and waste water (sewerage) services.
The Environment Agency works with these water companies to minimise the impact that their assets and activities have on the environment.
We monitor their environmental performance throughout the year against important objectives including reducing pollution incidents, complying with permits and delivering environmental improvement schemes. We publish an annual assessment of their performance.
