Southern Water nears completion of £11 million upgrades on the Isle of Wight

Three schemes, costing more than £11 million, are almost complete on the Isle of Wight – boosting treatment processes and environmental protection locally. 

Our wastewater treatment works in Roud, Shalfleet, and Calbourne have all had cutting-edge equipment installed and upgrades made to improve the quality of the treated flows leaving the site. 

The improvements are part of efforts across the island to better protect and enhance the environment, by upgrading our wastewater network and cutting storm overflows 

Improvement sites
The improvements carried out across the three sites include:  

  • Roud: Installing new sand filters, a sludge tank and installing a new treatment process called ferric dosing that will improve water quality 
  • Calbourne: Installing ferric dosing process. Further improvements include new tanks (humus tanks) that help remove solids from wastewater and refurbishment of reed beds.   
  • Shalfleet (below): Installing ferric dosing process, we are also improving wastewater treatment through refurbishing reed beds. 

Aston-Kolek: This work will make a big difference on the Isle of Wight
Project Manager for Southern Water, Taniko Aston-Kolek, said, 

“We’re under no illusions that we have to invest in our treatment works as part of our wider work to improve the health of our rivers and seas.

“This is our top priority and this work will make a big difference on the Isle of Wight and we’re excited to see it completed and looking forward to making further improvements in the coming years.” 

The work is being carried out by contractor GtB who are supporting Southern Water on a number of other key projects to treatment sites across its region, including recently at our Portswood works in Southampton

Richards: The teams across the sites have done a sterling job
Martin Richards, Project Manager for GTb, added,

“It’s great to see these projects nearing completion.

“We have more work to do and expect to finish by April 2025.

“The teams across the sites have done a sterling job, despite some really appalling weather conditions to keep these projects on track.”
