Improvements to your water network

We are constantly improving and embracing new ideas, new ways of thinking and new technologies to find the best possible solutions to repair water pipes, track down leaks.

Our innovation initiatives

Our Water Resources Management Plan outlines the improvements we’ll make to keep providing you with some of the best drinking water in the world.

The plans for all 5 of our Water Resource Zones will make sure we look after both you and the environment. 

By 2050, we will have achieved:

50%
reduction in leaks*
90%
of customers on smart meters
110litres
consumption per person per day
209million litres
less water taken from rivers per day

*compared to 2017/18 levels.

Other work we’re doing is specific to each zone:

Up to 2030: Investment: c£1m Litres saved: We’re investing in closer monitoring and network research before this can be calculated reliably.

Additional water made available: No new sources of water on the islands, and we can't bring water in from elsewhere. 

Projects up to 2050:

  • Using new water treatment systems to supply more customers
  • Supplementing groundwater sources with more desalination

Improvements to your wastewater network

Our Drainage and Wastewater Management Plan covers all the improvements we’re making to our wastewater network up to 2050. We’re determined to be a service you can rely on to protect the environment, handle wastewater responsibly and plan for future expansion.

We know there’s a lot to do, and we’re promising that by 2050 we will have achieved:

1,470hectares
surface water removed
510,000m3
of storage added
3,000km
sewers upgraded
110
treatment works upgraded

To do this, we’ve split the region into 22 catchments. Each area has a specific plan of improvements and upgrades that we’ll be working on. Some of the major projects include:

Increasing storm storage

At times of high rainfall the water flow into our treatment works currently hits levels well above capacity. So, by increasing storm storage capacity, we plan to reduce the number of times wastewater is discharged straight into water courses (rivers, sea etc) through storm overflows – down to 10 spills per year in any one location by 2050.

Separating combined sewers

To further help control the amount of wastewater ending up at our treatment works, we’re separating surface water (rainwater) from the foul sewerage. The surface water is released into watercourses with minimal treatment, freeing up the treatment works to more efficiently treat foul sewage from homes and businesses.

Upgrading our sites

In the next few years, we’ll be upgrading, improving, and even relocating some sites to protect them from rising sea levels, coastal erosion, and demand changes.

Proactive interventions

We’re collaborating with landowners on a wide range of land management solutions which will help keep our rivers healthy.

Creating green spaces for wildlife

We’re making our sites more wildlife friendly in our ground management techniques and protecting the wildlife like bats, birds and unique plants and insects that already live there.
