Southern Water has announced the early completion of a significant infrastructure upgrade, replacing ageing water mains under Horsebridge Hill on the Isle of Wight. The project, which began on January 26, involved the installation of a 500-meter (1,640-foot) plastic pipe, aimed at enhancing the reliability of water supplies and reducing the risks of bursts, leaks, and water discolouration.
This upgrade is part of Southern Water’s broader strategy to modernize its infrastructure and improve service delivery. The company has emphasized that such upgrades are crucial for minimizing disruptions to water supplies, which can have significant implications for public health and environmental sustainability.
In a related environmental concern, 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 threat to marine life, as birds, fish, and marine mammals may mistake them for food, leading to harmful consequences.
Southern Water operates a total of 367 wastewater treatment sites, of which 5 still utilize bio-beads, a technology deemed outdated. A petition with 9,915 signatures was presented to Parliament, calling for a ban on plastic beads in wastewater treatment, highlighting growing public concern over their environmental impact.
Southern Water is currently collaborating with the Department for Environment, Food & Rural Affairs (Defra) to explore options for updating the remaining sites that still use bio-beads. A spokesperson for the company acknowledged that while bio-beads were the best technology available when the Eastbourne site was built in the 1990s, advancements in wastewater treatment technology have since emerged.
Helena Dollimore, an advocate for environmental reform, stated, “I have since been working with the Sussex Wildlife Trust because the use of plastic beads in wastewater treatment is an outdated technology and better, modern methods exist.” This sentiment is echoed by Henri Brocklebank, who noted the well-documented impacts of bioplastics on wildlife, while also expressing concerns about the lesser-known effects of contaminants released in the digestive systems of affected animals.
As Southern Water continues to address these pressing issues, observers are keenly watching for updates on the implementation of modern technologies in wastewater treatment. The shift away from bio-beads could mark a significant step towards more sustainable practices in the water industry.
