South East Water’s expanded £22 million, state-of-the-art water treatment works upgrade in Bray, Berkshire, has been brought into action for the first time this week.

The water comany’s expanded treatment plant, which will help the company treat an additional 23 million litres of water a day, is making substantial progress.
This week, around six million litres of water was treated for the first time within sections of the upgraded treatment works before being pumped to customers’ taps.
Brian Steventon, Delivery Manager at South East Water, said:
“After three years in construction we are really excited to hit such a significant milestone with this project.
“The new tanks are now fully constructed and thousands of meters of cable has been installed to power them up. We have also fine-tuned many areas of the expanded works which has now enabled us to begin pumping raw water through it for treatment.
“This expansion is vital to ensure we can continue to supply top-quality drinking water as the community grows so I am very pleased with the progress the team has continued to make.”
The company will gradually increase the water treated at the expanded treatment works over the coming weeks.
At present, Bray Keleher Water Treatment Works can produce up to 45 million litres of water a day. Once the expansion is complete, it will produce up to 68 million litres of water.
Brian Steventon continued:
“This week, we are treating water using the new Clarifiers and Rapid Gravity Filters (RGFs).
“A vital part of the treatment process, the RGFs use a special type of sand to filter out any unwanted particles that can be found in raw water.”
The project is the largest investment of the decade by South East Water.
Craig Nienaber, Business Development Manager for Safe Access Solutions (SAS) at HUBER Technology, explores why the company is seeing a growing level of interest in its safe access solutions for critical infrastructure providers, including their application in wastewater treatment assets.
