Nine Danish partners have formed a consortium with the objective to demonstrate the use and effect of integrated high-end solutions within Leakage Management based on Danish technologies and know-how. The nine partners represent leading technology providers, consultants, water utilities and the Technical University of Denmark.


The project – named the LEAKman project – is initiated to demonstrate Danish solutions for reducing urban water loss and pave the way for new technological developments. It includes several vital aspects such as economic analysis of the return on investment, Economic Leakage Level (ELL), selecting appropriate KPIs for monitoring the status and effect of different leakage management solutions as well as the implementation of interfaces between the systems.

Two large-scale demonstration facilities have been initiated at the Danish water utilities Nordvand and HOFOR (Greater Copenhagen Utility). The demonstration facilities are using state-of-the-art tools and techniques in order to test, verify and optimise leakage management solutions which will reduce and maintain NRW at a level of 4-6%.

The approach integrates the four key elements of leakage management: pressure management, active leakage control, pipeline management and rehabilitation as well as speed and quality of repairs. The implementation includes installation and use of intelligent valves, pumps, deployed noise loggers, smart meters, smart inspections, SCADA, online hydraulic modelling (Aquis), GIS and a holistic management information system (HOMIS) configured for automated calculation, display and reporting of selected key performance indicators.

Many of these components are already in use at water utilities, however they are often installed as part of separate projects with only little or inefficient interface between the different components. As a consequence, the full potential of the entire system is never reached. A key point of the implementation is to establish seamless and generic interfaces between all components in order to optimise the value of each individual system when combined with the other systems.

The LEAKman project is a 4-year project under the Eco-Innovation Programme supported by the Ministry of Environment and Food which runs from 2016 to 2019 and has an overall budget of EUR 5.7 million.
