A precious resource

All the water that ends up in your home is reliant on one thing – rain. Rainwater is captured in our 23 reservoirs, over 3000 miles of rivers, and a few groundwater sources too. It's our job to transport this 'raw' water to our treatment works, and from there to your taps. We treat it to such a standard that your drinking water is some of the best in the world.

How we're improving our service to you

Day to day, our skilled technicians, engineers, and contractors manage and maintain the operation and performance of our drinking water network. This involves finding and fixing leaks, fitting meters, monitoring rivers and transferring water around the network to where it's needed.

Into the future, we have some major plans to upgrade our network to make it even bigger and better. These plans take us up to 2050 when we will have achieved:

50%
reduction in leaks*
100%
of metered customers on smart meters
110litres
consumption per person per day
173million litres
less water taken from rivers per day

*compared to 2017/18 levels.

To make these plans a reality, we’ll be working with our wonderful partners including the Wildlife Trusts, Historic England, the Environment Agency, the National Trust and local and district councils.

Our plan for your water

Dive into the detail

Dig into the nitty-gritty to learn more about the quality of your tap water. Or why not find out how much water you and your household use? A meter is just the piece of kit you need to start your water-use investigations.

Track your use and more

A meter will not just help you save water, but also money. Customers who install a meter usually end up £300-£400 better off because of it.
