    1. 1. Practical SustainabilityApproach, examples and results of implementing carbon targets and“Sustainability in Design” early in AMP5 to reduce carbonBusiness Council for Sustainable Development Nov 2012Peter CaldwellLead Sustainability Champion@one Alliance (working with Anglian Water)
    2. 2. Agenda• Who am I, and what do I do?• Board commitment & targets• Measures, practical approach and method• Examples• Overall results• Conclusions

    4. 4. @one Alliance Board Commitment to Sustainability (Nov 2009) Environmental impacts • Focus on reducing energy, carbon and waste. • Drive innovative, sustainable solutions. Social impacts • Deliver with the local community • Develop training that enhances the skills of our workforce. Economic impacts • Work with the local supply chain. • Develop and implement a policy on sustainable procurement.4
    5. 5. @one Alliance Carbon Targets AMP5 Area Targets 2010 to 2015 Baseline is best practice in AMP4 / Ofwat submission. Embodied carbon reduction 50% Operational carbon reduction 20% Capital Expenditure reduction 20% rising to 30%5

This product is an update of the AMP4 product, but the original product. Can embodied carbon reduction with design reduced to the minimum required to be achieved? achieve the plant requirements.

Product reduced from 2 tanks and large kiosk to single self bunded tank and small kiosk. Smaller base and ancillaries for installation required. Still full assembly of units off site and simple installation Detail of any other particularly sustainability activity undertaken on the project. Smaller systems will be much easier to install on small sites with difficult access Tichatonga Mhlanga – Supplier may also be useful for other products / applications Water Infrastructure Ke y Con ta cts IProcT Warren Bigwood Operations Simon Toulson Product Peter Caldwell8
    9. 9. Sustainability in Design Methodology Designers use a four stage hierarchy at the start of the project Build nothing Build less, Build clever Build with lower carbon materials Build more efficiently9
    10. 10. Build Nothing 1010
    11. 11. Build Less/ Build Clever • 30,000 population growth • Target cost £17m • Forecast below £15m • Embodied carbon - 65% • Operating carbon -120% • Effective OPEX saving over £230k/yr 1111
    12. 12. Build Clever/ Build with Lower Carbon Materials Conventional in-situ reinforced concrete Structured plastic with conventional bedding 34% cost saving 39% reduction in embodied carbon Precast concrete 28% cost saving 19% reduction in embodied carbon (50% reduction with cement replacement) Structured plastic in curved trench 38% cost saving 50% reduction in embodied carbon (55% reduction with SMR)12
    13. 13. Standard Products and Build off-site • Already off-site build in AMP4 • New single tank with reduced footprint • 40% reduction in embodied carbon • CAPEX savings forecast greater than 20% affordability • 29 projects will use this Standard Product13

    15. 15. Conclusions Carbon targets used to change design and project behaviours. Practical examples generated. A step change has been made. Embodied carbon reduced significantly. Operating carbon reduced significantly. CAPEX, OPEX and whole life cost reduced beyond target15
