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.
We invite you to explore solutions related to non-revenue water in more depth below, find potential partners, catch up on the latest related news and discover real-life case examples of how non-revenue-water solutions can help solve your environmental issues.
Challenge The city of Al Ain in the Emirates of Abu Dhabi (United Arab Emirates) is working towards a more sustainable water supply Solution The results were achieved through an integrated approach which included implementation of real-time hydraulic modelling, automated water balance calculations, installation of flow and pressure monitoring instruments as well as deploying noise […]
As the second most populous state in the United States, Texas has a growing demand for water. With a semi-arid climate, the state is prone to extreme droughts but still lots of distributed water is lost or never invoiced every year. These challenges can be addressed to meet current and future water needs by optimizing water management and reducing non-revenue water.
Mid-South Synergy in Montgomery, TX, operates a water service area with more than 5,000 metering points. The utility was looking for a solution that would give them a detailed overview of their distribution network with realtime information and smart alarms, which would help save resources.
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.
The City of Larvik has a customer base of 39,000 people. Larvik is also a holiday destination, and during summer of 2018, the municipal water treatment plants had difficulty meeting demand. Larvik has several pressure zones, altitudinous reservoirs and pumping stations. The distribution system has eight major districts, subdivided into 20 DMAs with 35 district […]
Good water management can make cities healthier places to live, resilient towards climate change and more sustainable overall. Without proper sanitation, sewerage and clean water supply, there is no liveable city. This white paper features lessons learned from different Danish stakeholders within urban water management. It is meant to serve as a tool for inspiration for creating innovative water solutions, which contribute to smarter and more liveable cities.
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.
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. […]
