The National Infrastructure Commission

“The National Infrastructure Commission is a permanent body which will provide the government with impartial, expert advice on major long-term infrastructure challenges. The objectives of the Commission are to:

• support sustainable economic growth across all regions of

the UK;

• improve competitiveness and
• improve quality of life

“The National Infrastructure Commission commits to delivering the following products and services:

• A National Infrastructure Assessment once in every

Parliament, setting out the NIC’s assessment of long-term infrastructure needs with recommendations to the government” Scope covers: transport; digital; energy; water & waste water; flood risk; and solid waste. Plus interdependencies and cross- cutting issues

The Commission’s plan of action for the UK’s infrastructure over the next 10-30 years Recommendations include:

• Nationwide full fibre broadband by 2033
• Half of power provided by renewables by 2030
• Three quarters of plastic packaging recycled by 2030
• £43 billion of transport funding for regional cities
• Preparing for 100% electric vehicle sales by 2030
• Ensuring resilience to extreme drought
• A national standard of flood resilience for all communities by

2050. Alongside these, better design and more efficient funding and financing can save money, reduce risk and create a legacy that looks good and works well. The government has committed to respond to the Commission’s recommendations and to adopt agreed recommendations as government policy.

Challenges: population growth

Estimated and projected total population, UK, mid-1981 to mid-2041

Challenges: climate change

Challenges: climate change impacts - drought

• Currently not all companies are resilient to the “worst historic drought”, approximately

a drought with 1% annual chance to occur.

• All regions are projected to be in deficit during such drought by 2050.

Challenges: climate change impacts – surface water flood risk

£300 million +40% Average direct damages to properties per year 2050s, 2°C global temperature increase Now

Challenges: environmental needs

1 in 5 surface water bodies and 1 in 3 groundwater bodies under pressure due to abstraction

Almost 1 in 10 rivers not in good ecological status due to land management, the water industry, and urban and transport pressures

Half groundwater bodies will not be in good chemical status by 2021

Other challenges

• Joined-up planning for water resources
• Long-term planning for wastewater and drainage
• Ageing drainage network
• Fragmented responsibilities for surface water management
• Lack of data on surface water networks

“A lack of reliable data has meant that it has not been possible to consider surface or waste water in detail for this Assessment. Surface water flooding is significant and there has been little progress in the decade since the Pitt review. Further work is needed urgently.” National Infrastructure Commission, 2018

Recommendations

• Government set a long-term strategy

and funding by 2019

• Water companies and local authorities

deliver joint plans for managing surface water by 2022

• The Environment Agency update

catchment plans by 2023

• MHCLG ensure new properties are

resilient and don’t increase risk elsewhere

• Increase resilience to drought, providing 4,000 Ml/day of additional capacity through:
• Water companies halve leakage by 2050
• Government enable and encourage widespread smart metering by 2030
• Ofwat enable the delivery of supply infrastructure by 2030s maximising transfers
• Ensure that communities are resilient to flooding 99.5% of the times by 2050 through:

Next steps

• On water resources, the government will respond formally but initial

indications and reactions from the industry are broadly favourable

• On flooding, we will look at companies to make tangible progress in

managing surface water in close collaboration with local authorities

• The government has yet to respond to our recommendations in full and will

publish a National Infrastructure Strategy next year

• The government has also tasked us to carry out studies on resilience and on

the regulatory system

• Further NIC work on the link between infrastructure and housing is

underway
