    Our region covers 5,000 square miles.
    We have 8.8m drinking water customers and 14m wastewater customers.
    We have 350 sewage treatment works and 66,500 miles of sewer network, a lot of which will end up at Beckton Sewage Treatment Works.
    We have the biggest capital delivery programme in the industry, worth £5bn between 2010 and 2015…
    We invest around £1bn each year on improving our water and wastewater network - replacing worn-out infrastructure and adapting to the needs of a growing population. This is more than any other UK water company.
    We have started work on some of the largest engineering projects in Europe, through our London Tideway Improvements Programme…
