East Sussex

Our £476.1 million investment in East Sussex will improve bathing water quality, protect the coastline, and build a stronger, more resilient water supply network for generations to come.

Cleaner seas, stronger supplies for East Sussex

Over the next five years, we’re making major improvements to protect East Sussex’s coastline and support local growth. This includes reducing the use of storm overflows and upgrading our wastewater treatment sites to handle more waste and remove nutrients—like phosphorus—before water is returned to the environment.

We’re also investing in your water supply. By rebuilding Weirwood Water Supply Works and expanding our network, we’ll support a growing population, reduce the risk of outages, and help keep local rivers healthy.

£53.3m in Brighton and Hove

We’re investing in local groundwater catchment schemes to protect the quality of our water supply. Millions is being spent to improve our Peacehaven site, reducing spills to protect local bathing waters and improving the treatment of sludge - a byproduct of the treatment process used by farmers. We also use the renewable energy created in the process to power our sites.

£30.3m in Hastings and Rye

To improve bathing waters and river health, we're improving wastewater treatment and reducing the amount of phosphorus returning to rivers at Ferry Hill, Winchelsea and Icklesham. We’re also investing £5.6m in Fairlight to cut spills in the area.

£65.2m in Bexhill and Battle

£21m will help us reduce spills in Hastings, Northiam and Westfield and protect local rivers and seas. We’re also improving the quality of treatment at our sites, removing phosphorus from wastewater returning to the environment, and monitoring flow better to reduce storm overflows. Further investment will increase resilience to flooding at our Battle and Catsfield sites.

£77.7m in The Sussex Weald

We’re investing £6.1m to reduce spills in Hailsham North and £6.9m to enhance wastewater treatment at Hailsham South, both bringing huge benefits to local rivers and seas. As part of our commitment to enhance water quality in over 1000km of rivers, we’re also reducing levels of phosphorus from treated wastewater returning to them. Upgrades to Halland Wastewater Treatment Works will increase the site’s resilience to flooding.

£36.8m in Lewes

£5.2m will help us improve the health of local rivers by removing more phosphorus – a potentially harmful nutrient - at our Plumpton and Ditchling wastewater treatment works.
