Southern Water has successfully completed the replacement of ageing water mains under a key road on the Isle of Wight, finishing the work ahead of schedule. The project involved installing a 500-meter (1,640-foot) plastic pipe, which began on January 26.
The utility company stated that this upgrade significantly reduces the risk of bursts, leaks, water discolouration, and interruptions to water supplies, enhancing overall service reliability for residents.
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 danger to wildlife, as birds, fish, and marine mammals often mistake them for food.
A petition calling for a ban on plastic beads in wastewater treatment garnered 9,915 signatures and was presented to Parliament. Currently, five out of Southern Water’s 367 wastewater treatment sites still utilize bio-beads, an outdated technology from the 1990s.
Southern Water is collaborating with Defra to explore options for updating these sites to eliminate the use of bio-beads, which have been criticized for their environmental impact. A spokesperson for the company acknowledged that bio-beads were the best available technology at the time of their installation, but modern alternatives exist.
Henri Brocklebank, an environmental expert, 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.” This highlights the urgent need for updated technologies in wastewater treatment.
Helena Dollimore, who has been working with the Sussex Wildlife Trust, emphasized the importance of transitioning away from plastic beads, stating, “The use of plastic beads in wastewater treatment is an outdated technology and better, modern methods exist.”
As Southern Water continues to address these environmental challenges, observers are keenly watching for updates on the transition plans for the remaining treatment sites still using bio-beads. Details remain unconfirmed.
