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

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!
