Global water loss - Danish solutions with LEAKman

The LEAKman project aims to demonstrate Danish solutions to reduce the loss of clean drinking water, as well as to pave the way for new Danish water technology.

LEAKman is a lighthouse project under the MUDP (Environmental Technology Development and Demonstration Program), which was awarded in the autumn of 2015 with a budget of DKK 43 million. The project brings together the largest in the industry of Danish water technology and expertise and includes in addition to Leif Koch A / S, Niras, Grundfos, AVK, Kamstrup, DTU, Nordvand, HOFOR and Shcneider Electric.

Unique Danish partnership fights against global water loss

The leakage level in the Danish drinking water distribution system is among the lowest in the world, with an average loss in supplies of less than 10 %. The low water loss on the pipeline network in Denmark is primarily a result of a long-term strategy for establishing rehabilitation processes, good craftsmanship and accurate measurements for water production and consumption. This, together with political initiatives, as well as a culture of water consumption without corruption, has resulted in us in Denmark having such a low water loss.

The LEAKman project works to create guidelines for selecting suitable instruments and techniques that can be implemented in water supplies worldwide. This can reduce water loss to the country's specific objective, and ensure a stable water supply. This includes several vital aspects such as economic analyzes of gain in reducing water loss, selecting appropriate key figures and criteria for success, as well as monitoring the effect of various leakage management solutions to select the most effective form of platform implementation between systems.

Denmark has know-how

Denmark has great know-how and some of the best high-tech solutions to reduce water loss on the mains.

Two large-scale demonstration facilities are being built at two large Danish utilities, HOFOR and Nordvand. The demonstration facilities consist of state-of-the-art instruments and techniques to ensure valid and effective testing of the leakage level. This is the basis for optimizing solutions in leakage management, with the aim to reduce the leakage loss to 4-6 %, and ensure that this level does not exceed this level in the future. The approach for the project follows IWA (International Water Association) customs and guidelines, for all four pillars of leakage management

The implementation of the demonstration facilities includes installation and use of intelligent valves, pumps, leakage loggers, intelligent meters and inspections, SCADA, online hydraulic modeling, GIS and a holistic management and information system configured for automatic calculations and reporting of selected success criteria and key figures. Despite the fact that several of these techniques are already used in the water industry today, they are often installed separately with no or little inefficient interaction between the components. One consequence of this is that the full potential of the system has not yet been reached.

An important point in implementation is to establish seamless and generic interfaces between all the components, in order to optimize the value of the individual systems when combined with other systems. These large-scale demonstration facilities will provide a unique playground of opportunities for practical analysis and investigation of effects and changes achieved through the implementation and combination of technologies. By implementing standardized user interfaces in future installations and systems, the installation costs will decrease, at the same time as the time with which the components are installed will decrease.
