Work in London
Improving our water and wastewater network is essential for delivery of our services. Our Victorian infrastructure wasn't designed for the demands of modern day London. Climate change and population growth mean our pipes are no longer fit for purpose.
So, we're working across London and the Thames Valley to bring our network up to date. Our planned maintenance programme will reduce leaks and supply interruptions for our customers.
