Climate change adaptation in the
renewal of Jönköpings water and
sewer systems
•Jönköpings under world consists of:
•Ca 800 km water pipelines
•Ca 720 km sewer pipes
•Ca 480 km storm water pipes
•Renewal of 9000 meter pipes or 3000 meter
ditch each year
•Rate of renewal shall raise from 500 year to
200 year (renewal from 0.2% to 0.5%)
•80% does not live up to functional (10
year rain) and conditional requirements

Rate of storm water / sewage
system renewal in Sweden
The systems are designed for 2-5 year
rain intensities! (100 year rains have
occurred)
Today Sweden invests 200 million Euro
per year in renewal of the drainage
systems
A rough estimation is that the pace of
renewal will grow 3 to 4 times during the
next 25 years
Is that probable, likely, feasible ?

Renewal strategy for piping systems
• Step 1: Prioritize pipes
• Step 2: Water flow directions and lowest points
• Step 3: City-area based renewal
Implementation:
• Inventory
• Responsibility division
• Prioritize (very high, high, medium, low)
• Response activity plans
• Detailed planning
• Realization
Instead of just looking at the age of the pipes, also look at climate change
impacts: 80% of system in need of renewal. Innovative renewal needed.

Aim is to integrate
•
the increasing demand for more houses and other
buildings with
•
the increasing need for more and better flood risk
management measures
•

France: Paris, Orléans
Belgium: Brussels, Leuven
Ireland: Dublin
Great-Britain: Sheffield
Germany: Mainz
Netherlands: Nijmegen

Översvämnings riskhantering & hydromodellen
När behöver man en hydromodell?
• Awareness: To show flood risks (where, cost,
frequency) and explain how to manage it
• Avoidance: To limit flood damage and ease
recovery by planning and adapting buildings,
infrastructure, surfaces and economic activities
and building capacity in individuals and
institutions to become more resilient
• Alleviation: To reduce flood risk by implementing
physical, technical, non-structural and procedural
measures for the management of water systems
• Assistance: To provide support to for a quick
recovery process by engaging and building
capacity in communities, and others prior to,
during and after flood events

When there is a flooding in your country …
Who is responsible?
Who will suffer?
What will be the losses?
What is your strategy?
Where do you start?
How fast can your region recover?
Who will take measures that it will not happen again?
Could it be prevented?
Different history – different strategy for future

Monograph conclusions
The Buzi River Basin, offers
considerable potential for economic
growth and development
Strategic location
Water Development Potential
Agricultural Development Potential
Moderate population density
Basic infrastructure in place in the
north part of the basin
Vulnerable to Floods and Cyclones
Challenges and Development issues
Regional Energy Scarcity –
Potential in the basin for HPP
Water for basic needs
Water for Irrigation
Disaster Management
Future Challenges
o Water Shortages (Water Supply and Irrigation)
o Energy Demand (regional)
o Extreme water events
Need for water infrastructure development!
