Our challenge

• By 2025, 1.8 billion people will live where water is scarce
• Water is fundamental to health, nutrition and energy
• Water security is a pressing concern due to population

Water security is a pressing concern due to population growth, climate change and drought

• The threat of flooding in both vulnerable and established
• The threat of flooding in both vulnerable and established

communities is increasing Water is a power source that is not yet being properly exploited

• Water is a power source that is not yet being properly exploited.

• Why is it happening?

Why are floods more visible?

• 70% of world’s populations already live in areas at risk of flooding

70% of world s populations already live in areas at risk of flooding

…Urban developments are frequently on rivers or by the sea for historical reasons.

• ‘Business as usual’ means that we are building more and

more in these locations

hi h b it lf i i k …which by itself increases risk…

• Add climate change risk
• Add climate change risk

…rising sea levels, increased storminess and higher intensity rainfall = even more risk.

• So, more stuff to be damaged + increasing likelihood = a double hit!
• Social commentary post-Pitt has raised awareness

…But Nature Check (October 2011) said government “failing” to implement

17

( ) g g Pitt Review.

What should we do?

• Planning must take place at a landscape or catchment level

to understand the many interactions y

• In a more tightly-packed world decisions are more complex

and need multi-disciplined response

• Systems approach is needed

We live in a world where food, water supplies, roads, power (etc) i t li k d are interlinked Systems approach to urban management to ensure the close interdependencies of water and economics are: – fully understood – and decisions are made in the interests of resilience.

18

Flooding around the world

• Flood risk management around the world has

different drivers and faces different challenges

• Case studies:
• UK
• Africa
• Middle East.

UK

Shaldon Shaldon

defence scheme

• Extensive consultation with the local community
• Protection to 453 properties against a 1 in 1,000

chance of flooding

• Other environmental improvements.

Teignmouth Teignmouth

• Atkins is producing this long term plan for

management of flood and coastal risk management of flood and coastal risk

• in light of climate change
• achieving UK and European legal

req irements for managing habitat requirements for managing habitat

• building robustness into the plan due to

longer term uncertainties.

Africa

Nzoia River, Kenya

• World Bank funded flood protection

project along 40km reach of river project along 40km reach of river

• Existing embankments have been failing

with increasing frequency since 1997 C d h d t d d

• Crops and homes are destroyed and

7,000 people (many subsistence farmers) are displaced when embankments breached breached

• The area is one of the poorest in Kenya,

largely as a result of the regular inundation inundation

• Atkins is assessing flooding issues in the

downstream section of the catchment, evaluating management options and evaluating management options and providing detailed design for the proposed approach.

Middle East

Wadi Hilti-Salahi Flood Protection Dams – Oman

• Flooding in Muscat and surrounding area

caused by Gonu cyclone in 2007

• Atkins has been contracted to carry out
• Atkins has been contracted to carry out

a feasibility study, detail design and construction supervision of flood retention dams

• Protection provided against floods up to

1,000 year return period

32

An increasing focus in UK?

• A number of resilience schemes in AMP5
• Two example projects:
• Severn Trent Water - Derwent Valley Aqueduct
• Wessex Water – Water Supply Grid.

33

Derwent Valley aqueduct

• Part of Severn Trent Water’s strategic water grid
• Supplies +200Mld to more than 590 000 customers across the East Midlands
• Supplies +200Mld to more than 590,000 customers across the East Midlands
• 200km of large diameter pipelines and tunnel sections
• Failure would result in significant loss of supplies

Failure would result in significant loss of supplies

• Atkins undertaking design of upgrades to improve resilience

and security of supply

• Development of a long term Asset

Management Plan

34

Water supply grid

• Wessex Water’s largest ever capital project
• Wessex Water s largest ever capital project
• Four key drivers:

– Security of supply Security of supply – Balance supply and demand over the next 25 years – Enable abstraction licences reductions – Address deteriorating ground water quality

• Approx 20 separate projects ranging from

larger trunk main schemes through to larger trunk main schemes through to more minor pumping station and local distribution upgrades.

• Atkins is undertaking concept review and

all engineering feasibility and design.

world dwarfing the biggest nuclear and coal power projects.

• The theoretical potential of worldwide hydropower is 2,800 GW,

The theoretical potential of worldwide hydropower is 2,800 GW, about four times greater than the 723 GW that has been exploited.

• The world’s biggest power plant is the Three Gorge Dam in China.

Most of the world’s largest hydroelectricity plants in the world are situation in China and South America. 20% f th ld’ l t i it i t d f h d d th

• 20% of the world’s electricity is created from hydropower and the

majority of this (80%) comes from 2,000 large schemes.

More than 50,000 small hydroelectricity plants around the world.

• Hydropower is a very efficient energy source because some turbines

can achieve efficiency of 95 % and more.

• In 1998, the hydroelectric plants of Norway and the Democratic

Republic of the Congo (formerly Zaire) provided 99% of each t ' d h d l t i l t i B il id d 90% f country's power; and hydroelectric plants in Brazil provided 90% of total used electricity.
