  1. D Dŵ ŵr r Cymru Cymru Microplastics: A Macro Problem

  2. The scale of DCWW’s work 1. 4 million customers across Wales, Herefordshire & Deeside Serving over 3 million population equivalent Operate 27,000km of water mains and over 36,000km of sewers 63 water treatment works, 840 wastewater treatment works and 91 dams and reservoirs 104 bathing water beaches

  3. Agenda DCWW approach Where next? Challenges Context Pathways

  4. Key pathways

  5. Pathways percentage

  6. DCWW’s approach to addressing marine litter & Microplastics Customer communications Policy and Legislation Water industry engagement + joint projects Research + collaboration Direct (short term) Action Asset Investment

  7. Stop the Block Education centre Customer communications TV and social media

  8. UKWIR projects Research body All water companies Flushables project - Improve labeling Microplastics & litter project -Quantity, type & potential source -treated wastewater, discharges from the sewerage system, drinking water and treated sewage sludge -Confirm the best analytical methods (type, size and quantity throughout the whole water and sewerage system) - Joint UK standard - Behaviour Change - Blockage investigations

  9. Refill campaign

  10. On site work and innovations Screening: Effluent entering works On site Event Duration Monitoring: Management of storm water Illegal connections: Investigating &correcting illegal/ misconnections Trialling of alternative filter bed media Monitoring level of 8 plastics Innovation Review of pipe lining Trialling alternative raking screens & macerators at inlet works Effect of dosing and coagulants

  11. Challenges to tackling Marine Litter • Monitoring: current monitoring focused on soluble chemical contaminants, not larger sewage-related debris. • Measuring: How to measure litter (parts per area/weight/impact) and micro plastics (size, number, mass, type)? • Engaging: industry engagement on packaging & reduction is complex • Locality: impacts not always felt at source

  12. Where next? What is the water industry’s contribution, how can we reduce it? What happens to plastics in different environments? Impacts upon food chain and human health? Would impacts on human health drive more rapid action? Better link marine litter to SDGs (goals 6, 11, 12, 13 and 14, 15)? Introduce a Fairshare principle / Market based instruments? Opportunity to innovate economic opportunity
