Enhancing rivers and seas
A £1 billion investment in a variety of Water Industry National Environment Schemes will improve 1,000km of rivers across our region.
Healthy environment including clean rivers and seas
We recognise the important role we play in protecting the environment. We’re continuing to reduce our use of storm overflows and improve water quality.
How we're doing things differently
As part of our Delivery Action Plan we’re improving the capability of our people, systems and processes to deliver our business plan to 2030.
Creating partnerships to move at pace
Eight of 10 agreements are now in place with local highways authorities, which will see sustainable drainage systems built into roads, helping to reduce storm overflow releases. By working with councils in this way we reduce planning time and costs.
Value for money in our supply chain
We’ve set up three new supplier frameworks to support our large-scale environmental projects so we can quickly source trusted suppliers, reduce procurement delays, and ensure good value for money while meeting regulatory targets.
A healthy network
To limit pollution to local rivers and bathing waters, since April 2025 our contractors have completed over 100 metres of sewer repairs. Pre-season health checks were carried out at 254 pumping stations and treatment works ahead of the start of 2025 bathing water season, with any required improvements swiftly actioned.
Working together to improve water quality
We’ve been working with partners and communities to tackle other sources of poor water quality. This includes identifying issues on the plumbing and pipework around local piers, as well as other illegal connections to our network.
Enhancing our environment
Across our catchment programmes, we’re delivering a broad suite of projects across our Water Industry Natural Environment Programme (WINEP), restoring precious chalk streams, improving water quality, removing obstacles within river channels, natural flood management through installation of leaky dams in the upper catchments, and more.
We’re moving faster with new partnerships
We’ve set up new supplier frameworks and expanded the existing ones, to help us deliver sustainable drainage projects more quickly, including a new one with partners in the voluntary sector.
Projects and schemes
We’ve created a clear Delivery Plan for the next five years, setting out what we’ll build, when, and how we’ll keep you informed along the way.

£262m
Invested this year of £906 million allocated to 2030 to upgrade our wastewater network and treatment works to increase capacity, reducing the use of storm overflows, has started.
£8m
Invested this year of £135 million allocated to 2030 to improve treatment processes at our wastewater sites – and the quality of water returned to the environment.
£41m
Invested of £367 million allocated to 2030 to improve the removal of harmful nutrients at sites across our region, such as phosphorus.
£11.6m
Invested of £230 million to remove excess nitrogen from the water we return to the environment from our wastewater treatment works.
Cutting storm overflows
Managing 1,556 million litres of wastewater a day, we’ll carry out hundreds of schemes before 2030 to improve the environmental quality of our water, reducing storm overflow releases along our coastline.
Becoming more sustainable
We’re introducing nature-based solutions, cutting carbon emissions and improving biodiversity.
