We invest around £1bn each year on improving our water and wastewater network - replacing ancient and worn out infrastructure, and adapting to the needs of a growing population. This is more than any other UK water company.
We have a number of major projects already in the pipeline, and have started work on some of the largest engineering projects in Europe - including our London Tideway Improvements Programme.
