Work to replace ageing water mains under a key Isle of Wight road has finished early, according to Southern Water. The project involved replacing an old main with a 500-meter (1,640-foot) plastic pipe, which commenced on January 26.
Southern Water stated that this upgrade is expected to significantly reduce the risk of bursts, leaks, water discolouration, and interruptions to water supplies for residents in the area.
In a related environmental concern, millions of bio-beads washed up onto Camber Sands beach in November last year after a screening filter failed at Southern Water’s treatment works in Eastbourne. These plastic beads pose a threat to wildlife, as they can be harmful if ingested by birds, fish, and marine mammals that mistake them for food.
A petition to ban the use of plastic beads in wastewater treatment was presented to Parliament, gathering 9,915 signatures. Currently, five of Southern Water’s 367 wastewater treatment sites still utilize bio-beads, which have been criticized as an outdated technology.
A Southern Water spokesman acknowledged that bio-beads were the best technology available when sites like Eastbourne were built in the 1990s, but emphasized the need for modern alternatives.
Helena Dollimore, who has been collaborating with the Sussex Wildlife Trust, 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have since been working with the Sussex Wildlife Trust because the use of plastic beads in wastewater treatment is an outdated technology and better, modern methods exist.”
Henri Brocklebank highlighted the potential dangers of bioplastics, noting, “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.”
Southern Water is currently working with Defra to explore options for updating the sites that still use bio-beads, aiming to mitigate the environmental impact of their wastewater treatment processes.
As these developments unfold, observers are keen to see how Southern Water will address the ongoing concerns regarding plastic pollution and the effectiveness of their wastewater treatment practices.
