Southern Water Completes Key Infrastructure Upgrade Early

Southern Water has completed work to replace aging water mains under a key road on the Isle of Wight earlier than anticipated. The project involved the installation of a 500-meter (1,640-foot) plastic pipe, aimed at reducing the risk of bursts, leaks, water discolouration, and interruptions to water supplies.

The upgrade began on January 26 and was part of Southern Water’s ongoing efforts to enhance infrastructure and service reliability. “We believe the ideal is to ensure FOG material is kept out of the sewer network and managed in a way that delivers clear environmental, operational and regulatory benefits – that’s why FOG Network 2026 is so important,” stated John Cunningham.

In a related environmental issue, millions of bio-beads washed up on Camber Sands beach last November after a screening filter failed at Southern Water’s treatment works in Eastbourne. These plastic beads pose a significant threat to wildlife, as they can be mistaken for food by birds, fish, and marine mammals.

Currently, five of Southern Water’s 367 wastewater treatment sites still utilize bio-beads, a technology considered outdated. A petition to ban these beads in wastewater treatment garnered 9,915 signatures and was presented to Parliament.

A Southern Water spokesman acknowledged, “Bio-beads were the best technology available when sites like Eastbourne were built in the 1990s where previously there were no sewage treatment at all.” However, the environmental impact of bioplastics is concerning. Henri Brocklebank noted, “The impact of bioplastics accumulating in the digestive systems is well documented, but the effects of any contaminants that could be released in the acidic gut systems of these birds are far less understood.”

Helena Dollimore has been actively working with the Sussex Wildlife Trust to address the use of plastic beads in wastewater treatment, emphasizing that better, modern methods exist.

Southern Water is currently collaborating with Defra to explore options for updating the remaining sites that still use bio-beads. Observers expect that these discussions will lead to more sustainable practices in wastewater management.
