Eastbourne Wastewater Treatment Works upgrade

We are investing almost £16 million to upgrade the treatment processes and make other improvements at the works.


Every day the works treats up to 86 million litres of wastewater from about 140,000 people in the area.

As it is now 16 years old, some of the site’s equipment requires refurbishment and we are taking the opportunity to make further improvements.

They include:

  • Refurbishing the biological filter which uses bacteria to digest waste
  • Improving lighting, ventilation and odour control inside the building
  • Replacing pumps and other operational equipment.

As most of the work is happening underground, specialist rescue teams are on-hand 24-hours-a-day to keep our workers safe.

As part of the ongoing improvements, part of the promenade has been closed. A cycle path and pedestrian path are in place as a diversion

The underground treatment tanks containing the main treatment processes.

Some parts of the work are already under way and we have now completed our refurbishment of the site’s treatment tanks.

This has already resulted in further improvements to the quality of the treated wastewater returned to the environment.
