Transcript

  • 1. Innovation through Carbon ICE/APM Prestige lecture Chris Newsome Director of Asset Management Anglian Water 1st July 2013
  • 2. Driving Innovation through Carbon Reduction ICE/APM Prestige lecture Chris Newsome Director of Asset Management Anglian Water 1st July 2013
  • 3. Our Love Every Drop goals Backed up by over 100 commitments and measures
  • 4. Halve our embodied carbon in new assets we build by 2015 from a 2010 baseline Reduce our operational carbon emissions by 10% in real terms by 2015 from 2010 baseline
  • 5. Moving beyond operational carbon Operational carbon Embodied carbon Most forward looking organisations are reducing operational carbon. Leading organisations are reducing embodied and operational 487,659 Tonnes annual greenhouse gas emissions (of CO2e) £45,568bn Gross asset value (replacement cost) Around 2bn 5 year capital investment Our carbon footprint
  • 6. Managing Embodied Carbon Don’t build Build less Use materials with lower embodied carbon Use fewer materials/reduce waste Process Tools Governanc e Perceived barriers ???
  • 7. Belief – Back of a ‘fag packet’ calculation and a public platform • Example HPPE SDR17 in road • Pipe material only 11% of total CO2e • 89% for excavation, laying, backfill Pipe Material Excavation Laying Backfill and re- instatement B D C Ground level Pipe OD C1 C2 C3 C4 D1
  • 8. 9 Future Opportunity : Sustainable drainage systems..
  • 9. 10 Proof of Concept – ‘Our First Standard Product’ : the Wootton booster…….  Simplified design process and procurement  Installation reduced from 15 days to 1 day  Reduced waste and re-work  Time on site reduced by 50% - 3 weeks  Highest quality, consistently, at a lower cost  Health & Safety risks reduced
  • 10. 11 Orthophosphoric acid dosing The Mark II product provides a reduced footprint dosing plant. Savings are made by buying in bulk (enabled by programme visibility) and by reducing the amount of design, installation and commissioning. Saving of 23% on the cost of the product core Saving of ~10% on embodied carbon AMP 5 Standard Products : Focus on Carbon & Cost Air valves Smaller and lighter than traditional AVs and more efficient. Saving of 36% on the cost of the product core Saving of 93% on embodied carbon Valve chambers A telescopic sheath for the valve spindle eliminates the need for a traditional chamber and reduces installation time. Saving of 50% on the cost of the product core Saving of 27% on embodied carbon P removal 1 tank instead of 2 and reduced footprint. Saving of greater than 15% on product core Targeting 50% reduction in embodied carbon High efficiency aeration Approximately 30% less air is needed with this product, resulting in corresponding lower energy requirements for the blowers. Savings of 86% on Whole Life Cost Savings of 25% on Whole Life Carbon Polydosing Cost saving of 15% on product core Saving of 12% on embodied carbon
  • 11. Precast concrete Precast concrete units provide a more cost effective solution than plastic for certain ground conditions. 28% cost saving 19% reduction in embodied carbon (50% reduction with cement replacement) Structured plastic with conventional bedding Lower cost solution with lower embodied carbon, but still requires bedding and surround to be craned into position. 34% cost saving 39% reduction in embodied carbon Conventional in-situ reinforced concrete Conventional techniques are labour and materials intensive. Structured plastic in curved trench A specially fabricated bucket enables a curved- bottom trench to be dug, making significant savings on imported bedding and surround materials. 38% cost saving 50% reduction in embodied carbon (55% reduction with SMR) Early AMP 5 : Innovation in our supply chain

  • 18. What happened : REDUCED CARBON REDUCED COST • Design engineers rose to the challenge – Released from focus on cost and standard design • Key Framework Partners & suppliers energised to deliver low carbon solutions • Strong link between lower embodied carbon and lower CAPEX • Design engineers and suppliers challenged AWS to improve measurement & management – Strong illustration that reducing carbon matters to them !
