  1. Building & Infrastructure Martyn Hulme Deputy Chair of the AGMA Environment Commission & Managing Director of Co-operative Estates

  2. Adapting the city

  3. Buildings and infrastructure workshop EcoCities research summary Jeremy Carter Research Fellow, University of Manchester, School of Environment & Development

  4. Recent trends in GM weather and climate events

  5. Consequences of weather/climate events in GM

  6. Critical infrastructure and the built environment in GM

  7. Susceptibility of GM infrastructure to flood risk • 7% of hazardous substance instillations in flood zone 3 • 6% of motorway junctions in flood zone 3 • 5% of fire stations in flood zone 3 • 2.4% educational establishments in flood zone 3

  8. The EcoCities Spatial Portal Mapping flood zones 2 and 3, and educational establishments. Mapping the urban heat island and residential care homes.

  9. Human comfort in office buildings • Productivity and health of workers are associated with thermal comfort in offices • Level of control over temperature and ventilation in offices is crucial for employees’ comfort, health and productivity. • Landlord regarded as responsible for physical building changes, tenants for adjusting behaviour. • Behavioural adaptation measures affected by common reliance on air conditioning and the variability of tenant companies. This study used Arup Appraise data

  10. Urban green/blue infrastructure Artificial wetland • Benefits of green infrastructure • Reduced surface runoff • Moderating air temperatures • Improving air quality • Protecting and enhancing biodiversity • Providing recreation space • Reducing carbon emissions Green roof Flood detention basin

  11. Oxford Road: green infrastructure scenarios Business as usual 15% green space High development 4% green space High development = +5ºC Business as usual Deep green 34% green space Deep green = -6ºC ~21% green space will maintain surface temperatures at baseline

  12. Greater Manchester – future land use scenarios Long descent scenario 2050 Upward Spiral scenario 2050

  13. Summary • Weather/climate risks to buildings and infrastructure are evolving • Today’s developments will be operating in a different climate regime in the future • New developments need to be resilient to future climate change • Adaptation needs to mix physical and behavioural responses • Green and blue infrastructure is a valuable adaptation response • Climate change projections should ideally be considered alongside socio-economic projections.

  18. Building & Infrastructure Mike Kay Network Strategic Director, Electricity North West

  19. The challenge for the wires • Decarbonization of generation, of space heating, and of transport • Managing more extreme weather – flooding and wind storms • Increase in average temperatures

  20. Electricity North West • We serve only the North West of England and we are based here • We serve approximately 5 million people at 2.4 million domestic and industrial locations • £9bn of Network Assets58,000km of cable96 bulk supply substations363 primary substations34,000 transforming points

  21. Carbon • A doubling of electricity usage by 2050? • Smart grids; smart meters – smart cities • Electric Vehicles • Innovation – Capacity to Customers (C2C) to reduce the new build capacity needed; make it available quickly and without digging up the streets

  22. The weather • Electricity North West is defending its critical infrastructure • Significant investment in flood defences

  23. Ambient temperature • Any rise in temperature is bad for electricity networks • Load growth is a much bigger effect, and ambient temperature rise will be accommodated in our changes overall

  25. Adapting the city

  26. Water Infrastructure & Climate ChangeChris Matthews Head of Sustainability, United Utilities

  27. Presentation Overview • About United Utilities • What climate change means for water and wastewater service provision and why this is a business imperative • Our response – water supply • Our response – wastewater service • Engaging with stakeholders – how we all need to work together

  28. About United Utilities • Operations in the north west of England • 7 million customers • 57,000 hectares of catchment land • Over 40,000 km of distribution mains, supplying 1950Ml/day water • Over 72,000km of sewers, 582 Wastewater Treatment Works

  29. Adaptation and water supply • 2035 estimate is a reduction in available supply of some 10% or around 180 million litres of water every day • A combination of less yield and greater customer demand • Intense rainfall may increase raw water colour increasing treatment costs • Flooding on water treatment facilities, interruption to service

  30. Adaptation and wastewater service provision • Increased incidences of flooding of homes • Flooding on wastewater treatment facilities, interruption to service • Water courses could have a lower dissolved oxygen content leading to tighter discharge consent standards to maintain water quality standards • Potential for odour generation in warmer conditions and risk of causing nuisance to customers • Impact on sludge as prolonged wet periods may restrict sludge to land recycling route • Warmer weather may have a positive effect on biological treatment processes, which operate more effectively at higher temperatures

  31. Our response – the process • Adaptation integrated into our Strategic Direction Statement, company policies and strategies to develop optimised long-term asset management plans for the next 25 years. The plans provide the foundation for assessing the specific actions required to adapt to climate change risks over the planning horizon and beyond. • Climate change data (UKCIP) and assessment of risk is used in the development of company strategies, whilst climate change is accounted for in design, construction and operational activities.

  32. Our response – water supply • Water Resources Management Plan • Reduce demand for water (leakage control and customer efficiency) • Increase supply of water (small scale new groundwater resource development and greater network integration) • 55 km West-East pipeline to link Lake District and Welsh sources and enable water to be moved to those areas most affected by climate change especially during drought period • £1.6m investment to manage flood risk at key assets and catchment land investment • All in a way that is good value for customers and is sustainable

  33. Our response – wastewater service • Increased volumes of storm water exceed sewer capacity and cause customer flooding. • Upsizing priority sections of sewer together with protecting customers’ property • Improving models of the sewer network • Engaging with local authorities and the EA on development of Surface Water Management Plans • On-going planning to protect wastewater treatment works at risk from flooding • Increasing emphasis on demand management approaches • Sustainable drainage systems (SUDS) analysis • Building our way out of the problem on its own will not work and we already have a policy NOT to routinely upsize the sewer network • Working with our customers to determine the level of service/protection that they want/can pay for

  34. Engaging with stakeholders • Engagement to understand stakeholder priorities and preferences • Taken into account within our strategic asset planning process. • Flooding from the sewerage system a symptom of more widespread problems in an entire drainage system which will often require actions from other stakeholders as well as United Utilities. • Support the adoption of a joined-up approach to drainage management based on the principles of integrated drainage as outlined in Making Space for Water (Defra, 2005), Future Water (Defra, 2008), the Pitt Review (Sir Michael Pitt, 2008) and Flood and Water Management Act (2010).

  35. Key messages • Sustainable adaptation to climate change will involve partnership working and behavioural change. We expect the proportion of this type of work to increase as conventional solutions become unsustainable. • Climate change risks to our Water Service are well catered for in our existing business plans and statutory documents. We already plan for climate variability in our 25 year business planning horizon. • There are some long-term risks to our Wastewater Service from climate change. Current methods to manage these risks are unsustainable and innovation is needed to manage the issues in the long term.
