Tailoring a holistic NRW strategy that fits local circumstances to reduce urban water loss
According to the UN, global water consumption will increase with up to 30 percent by 2020. In order to meet the future demand, there needs to be a strong focus on efficient water distribution. Non-Revenue Water (NRW) or urban water loss is a major global challenge as 25-50 percent of all distributed water globally is lost or never invoiced due to illegal connections, inaccurate billing systems, inaccurate metering, physical leakages, deteriorating infrastructure, wrong water pressure management etc. Danish water utilities have managed to achieve a national NRW average of just 8 percent. Each utility has developed its own strategy tailored to local circumstances, which typically includes a holistic NRW master plan, ongoing monitoring and pressure management and using high quality components such as water meters, valves, pumps and pipes.

New EU directive map out how drinking water quality and supply can improve across the EU. Denmark has helped to focus on water waste in the revised EU directive aimed at ensuring consumers healthy and clean drinking water.
Like many other countries, South Africa faces severe challenges in terms of water and energy security. Danish companies and authorities aim to assist South Africa to catalyse their green transition and meet water challenges at African Utility Week 2019.
In 2011, the water utility TREFOR Vand carried out an analysis of its water loss to address its high NRW issue. Afterwards, an action plan for 2012-2014 was developed using the IWA methodology. The action plan included implementation of KeyZones, pressure management, active leakage detection and optimisation of operation procedures. All mechanical meters have been […]
In the capital region of Denmark, they listen carefully to their water distribution networks. The country’s two largest water suppliers, HOFOR (Greater Copenhagen Utility) and Novafos, have transformed parts of their water distribution networks around Copenhagen into full-scale demonstration areas with state-of-the-art technology
25-50% of all distributed water globally is lost or never invoiced due to illegal connections, inaccurate billing systems, inaccurate metering, leakages, deteriorating infrastructure and wrong water pressure management etc. – or in short Non-Revenue Water (NRW). This white paper examines how water utilities can improve efficiency and meet future demand for water by reducing Non-Revenue Water.
We are happy to introduce WaterRehab; a unique tool for making pipe rehabilitation planning smoother and much more efficient. The pipeline network typically counts for up to 70% of the total volume of assets in water utilities. Therefore, even a small improvement of the rehabilitation strategy will result in huge savings in the distribution system. […]
As a supplier of drinking water, everything counts in providing the full picture when adding up duties and the economy. The new intelligent water meter MULTICAL 21 does not only measure the water consumption. It also improves the economy, facilitates the administration and prevents leakages from evolving. The advantages of the MULTICAL 21 water meter […]
In order to identify the possibilities for reducing non-revenue water in Hanoi, EnviDan has conducted a feasibility study, which points out the way forward in relation to NRW-reduction. The focus of the study has been to find the current Non Revenue Water (NRW) level and to make a cost/benefit analysis to improve the existing condition. […]
