Indonesian - Danish Water Days19-21 February 2009
An Introduction to Danish water services and knowledges
Jesper Goodley Dannisøe
Danish Water Research goes into action!!
Danish Water Knowledge
Short overview of problems and topics• Water resources management
– Policy & Management– Water supply– Waste water treatment– Surface waters
• Water & Agriculture• Climate challenges• Water Foot Prints• Water & Energy
Water Resources: A few topics!
Policy & ManagementWater supplyWaste water treatmentSurface water management
Policy & Management
• Without proper IWRM => Potential for water problems• Implementation of IWRM in many countries• Drafting laws, by-laws and regulations• Provide training and capacity building in water
authorities• Develop guidelines and manuals for daily
administration of water resources.• Integrate IWRM into local and regional planning
Integrated Water Resource Management, IWRM
Policy & Management
• Planning properly in the urban areas can reduce impacts• Accepting that Urban areas are important for water
resource administration• Arising awareness in the community to help in
combatting floodings• Support local initiatives for urban water resource
management.• Integrate IUWRM into local and regional planning
Integrated Urban Water Resource Management
What are the priorities of a city ?
1. Drinking water
2. Sanitation / sewers
3.Wastewater treatment & reduction of flooding
4. Reduction of pollution in recipients
5. Recreative values of water
Stormwater drainage - an integral component of urban environmental management
Have you seen this before??
And who are often the victims during floodings?
Water supply
Danish water supply based on groundwater for more than 100 years
Chemical p

n !!!!!
Danish non-revenue water!
5-10 %• People report leakages
• Supply companies have leakage teams and modern tracking equipment
• Plans for pipe rehabilitation a tradition!
• Because water has a value !!!
Why ?
…and waste water treatment
National water plans from 1987• All systems upgraded•Max 8 mg Total Nitrogen•Max 1.5 mg Phosphorus=> Increase in process and construction knowledge
Waste water systems = both combined and separate sewer systems
Main sewers of Copenhagen built 1857 – 1865, and still OK!
Surface water
Introducing the use of biomonitoring!
• Using different biological indicators for assessment of the surface water quality
• Quick
• Cheap (after it has been adapted to local bio-conditions)
• Reliable
• …but does not rule out traditional chemical assessment!

Assessment Forecast
Irrigation and proper crops
• Shift from traditional irrigation methods to ”more crop-per-drop” methods
• Assessing crops and their suitability versus climate
• Tax on water for irrigation => better use of the water
Climate challenges
Wet gets wetterDry gets drier
Increased energy consumption to handle water
Climate change
Increased CO2 emission
The vicious circle
Water conservation!
With the aid of Danish companies you can:• Preserve water, when it is there!
• Avoid loss of water in piping systems
• Consider recharging the groundwater resources!
• Handle floodings intelligently
• Prepare the urban areas to handle floods
• Introduce Water Foot Prints
Climate impacts on sewer systems
In Denmark more precipitation, but in shorter and more heavy bursts!
Result: Flooding
Action: Intelligent modelling, forecast and control
Modeling of flooding in cities
…or even worse!!!!!
Water Foot Print!
Examples of water foot prints
The good news: drink more beer!Product Water consumed
Liters1 glass of beer 751 cup of coffee 140 1 glass of milk 2001 cotton T-shirt 20001 hamburger 24001 liter bio-ethanol 25001 pair leather shoes 8000
Summing up!
• Danish water knowledge is active in all sectors
• We have learned from experiences and have adapted our approaches accordingly
• We believe that we can provide you with state-of-the-art solutions
• Danish water research take all levels from the water cycle into account => Research with results!
• …and we are very modest!!!
Thank you for your attention!And see you later!
