Solving water loss for life

Water network performance solutions

Non-revenue water

The challenges facing water utilities

Within discussions centered around sustainability, water scarcity, and the conservation of precious resources, one topic regularly covered is how utilities can better solve the challenge of water loss within their network. The need to protect precious resources and reduce water loss to more acceptable levels has made non-revenue water (NRW) one of the most challenging problems for water utility owners and operators to overcome.

Non-revenue water is the difference between the water entering a distribution system and the amount billed to water consumers. NRW is not the only actual loss of water, such as leakage or pipe bursts, but it also can impact all levels – from water abstraction to billing. Causes are as diverse as they are complicated to identify and measure, making NRW a major topic to ensure the future of resilient utilities.

One community, one purpose

How we're already helping to solve water loss globally

Anergy network, Lucerne, Switzerland

  • Ecological energy from the lake/sustainable heating and cooling anergy network To meet the requirements of a sustainable energy policy, Swiss municipality EWL is using ecological energy from Lake Lucerne as a sustainable heat carrier for heating and cooling of 7,000 households.
  • Additionally, they are saving up to 10,000 tons of CO2 per year with help of ELGEF Plus couplers with active reinforcement and prefabricated fittings to save valuable installation time and costs.

iRETI, Italy

  • IRETI supplies water to over 2.5 million customers in almost 300 municipalities in Northwest Italy, with a network of roughly 20’000 kilometers. The water loss in Italy is on average 37%.
  • Also IRETI faces the challenge of non-revenue water and with it the associated maintenance and asset lifetime. The innovative NeoFlow pressure regulating valve (PRV) by GF Piping Systems is providing the solution.

HSY Helsinki, Finland

  • GF Piping Systems supported the Finish utility, Helsinki Region Environmental Services Authority (HSY), to operate a reliable water supply system while complying with stringent environmental objectives.
  • GF Piping Systems provided data on the CO2 footprint of ELGEF Plus fittings, PE systems that highlighted the reduction in CO2 emissions by more than 80% when compared to metal systems.

FARYS Water Utility, Gent, Belgium

  • Retrofitting of large diameter transport lines in densely populated city areas often confronts water utility companies with major challenges.
  • The trenchless installation, combined with Ultrasonic Non-Destructive Testing (NDT) minimized risks and increased peace of mind.

$39 billion annually.

Lost water is lost revenue

It costs $39 billion annually for utilities. 1/3 of utilities report loss of more than 40% due to leaks.

77 liters per day.

Preserve what is precious

What if you could save 77 liters of water per day? This is the amount of non-revenue water per capita which is lost down the drain.

225.000 tons of CO2.

Make a difference

In the US a 5% reduction of water leakage can save up to 225,000 metric tons of CO2 annually, the equivalent to the annual CO2 emissions of 14.000 US citizens


A Cost-effective And Sustainable Solution In Fighting Global Non-revenue Water

Due to the globally aging water distribution infrastructure, non-revenue water (NRW) is a major issue for water utility companies worldwide. Retrofitting existing water networks with modern pressure management systems helps avoid leakages and lost water.

(Don’t) Waste Water Podcast: How To Save 126 Trillion Liters A Year? Solve Non-Revenue Water!

Some of the things that were covered:

  • How Non-Revenue Water represents 126 billion cubic meters a year and an achievable saving potential of $37 billion a year
  • How the Non-Revenue Water (NRW) question is intricate and multi-faceted
  • How water you lose on your network not only represents a direct cost but also an indirect one, as you have to produce new water accordingly

GF Piping Systems launches NeoFlow pressure regulating valve: the polymer balancing cure for water utility networks

Co-developed with OFUI NeoFlow pressure regulating valve (PRV) allows water utilities to easily implement pressure management technology and benefit from a renewed water network, a solution to avoid non-revenue water. The compact polymer valve is nine times lighter in weight and uses 40% less installation time than a standard metal PRV.
