Our Love Every Drop goals

Backed up by over 100 commitments

and measures

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

Moving beyond operational carbon

Operational carbonEmbodied carbon

Most forward looking organisations are

reducing operational carbon.

Leading organisations are reducing embodied

and operational carbon.

487,659 Tonnes annual greenhouse gas emissions (of CO2e)

£45,568bn Gross asset value (replacement cost)

Around 2bn 5 year capital investment programme

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

Orthophosphoric acid dosingThe 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 coreSaving of ~10% on embodied carbon

AMP 5 Standard Products : Focus on Carbon & Cost

Air valvesSmaller and lighter than traditional AVs and more efficient.Saving of 36% on the cost of the product coreSaving of 93% on embodied carbon

Valve chambersA 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 coreSaving of 27% on embodied carbon

P removal1 tank instead of 2 and reduced footprint. Saving of greater than 15% on product coreTargeting 50% reduction in embodied carbon

High efficiency aerationApproximately 30% less air is needed with this product, resulting in corresponding lower energy requirements for the blowers.Savings of 86% on Whole Life CostSavings of 25% on Whole Life Carbon

PolydosingCost saving of 15% on product coreSaving of 12% on embodied carbon

Precast concretePrecast 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 concreteConventional techniques are labour and materials intensive.

Structured plastic in curved trenchA 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)

Use materials with lower embodied carbon

Use fewer materials/reduce waste

• Low Carbon Challenge Solution•Temporary tanks to allow isolation•Shotblast & re-coat existing tank•Original design 166 tonnes embodied carbon•New design 3 tonnes embodied carbon•Saving in embodied carbon and reduction in use of finite materials from the environment

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 !

Embodied Carbon and CAPEX percentage change 100% CAPEX = baseline , 100% Embodied carbon = baseline

• New sustainability toolkit informs the decision making process of a project

• It ensures engineers are aware of their impact on sustainability during the design phase of a project

• Provides them with the information to assess the interrelationship between carbon, waste, cost and water usage
