In an interview with Jo Bradley from Stormwater Shepherds, hosted by GreenBlue Urban, the discussion revolves around sustainable drainage systems (SuDS) for managing highway runoff pollution. Jo emphasises that current solutions often overlook the severe pollution from highways, which includes toxic metals and hydrocarbons. SuDS can handle low to medium-traffic roads but are inadequate for high-traffic areas, which need more detailed design and maintenance.<\/p>\n
Jo criticises the lack of attention and maintenance for existing drainage systems, partly due to budget constraints and lack of statutory duty. She proposes a stormwater utility levy to fund the maintenance and operation of these systems. Joe also stresses that while SuDS provide multiple benefits, they rarely create significant wildlife habitats and should not be relied on solely for biodiversity net gain.<\/p>\n
To address water quality, Jo advocates for a holistic approach that includes considering all pollution sources, not just focusing on combined sewer overflows (CSOs). She calls for more public awareness and involvement in managing stormwater pollution, including reducing water use, avoiding flushing harmful materials, and creating meaningful habitats for wildlife in urban areas.<\/p>\n
