Public awareness and economic incentives to reduce NRW
Denmark has shown that economic growth and decreasing resource consumption are not mutually exclusive; they can, in fact, go hand in hand successfully.
Over the past 30 years, Denmark’s GDP has increased by 75 percent while the water consumption has decreased by 40 percent. The Danish approach, consisting of continuous public awareness concerning the importance of saving water together with economic incentives, has resulted in water consumption figures that are acknowledged worldwide.
Politicians and decision makers in Denmark have understood that public regulation and taxes are important and effective tools for behavioural change. In 1996, a general requirement was introduced for the installation of water meters at the consumer level in Denmark, giving private households access to their water consumption data. Furthermore, Danish authorities impose an annual penalty on water utilities that do not maintain their NRW level below 10 percent through extra taxes on lost water.
In 2024, the total price for water supply and wastewater treatment was an average of EUR 11.01 per cubic metre. The same year, water consumption in Denmark per capita was on average 97 litres/day, showcasing that the price of water can serve as a strong incentive for the public to reduce consumption.
The national average for NRW has been reduced to 7.5 percent due to the long-term intervention. Moreover, government regulations have motivated water utilities and technology providers to develop new, cost-efficient leakage monitoring technologies and leakage management systems. The highly efficient Danish water distribution system can also be reflected in the fact that the average ILI has remained below 1.0 for many years.
