    Tackling Non-revenue water

    Providing clean and safe drinking water day in, day out isn’t as easy as it sounds. To get the tap water you really want – clean, safe, and drinkable – there’s an entire chain of drinking water and wastewater treatment processes behind. And that has its price. Complex plants and pipe networks need to be built, operated, and maintained to provide a reliable municipal water supply. And the high investment, operational, and lifecycle costs are the reason why every drop is valuable. Treated water that is lost within the system and can’t be billed – non-revenue water (NRW) – is therefore an economical issue for water utilities and has to be minimized as fast as possible. The clock is ticking. And not just because of the financial loss but also because of potential ecological and humanitarian reasons.

    Listen to the flow, find the leak

    Aging pipe networks, difficult temperature conditions, vibration caused by construction work – there are many causes for leaks in water infrastructure. Unfortunately, leaks often appear beneath the surface where nobody can see them until it’s too late. Billions of drops, millions of cubic meters of drinking water are lost by many water utilities due to leaks every year. How can you minimize these losses? Not just to prevent the lost revenue, but also to conserve the vital resource, to keep drinking water clean, and to prevent buildings and infrastructure from dangerous undercutting. There’s a smart way for water utilities to ensure constant leakage detection with minimal effort. And we’re going to explore it.

    Measuring water consumption in the digital age

    Every year, millions of households wait for the manual readings of their water meters, having to stay home or organize friends or neighbors to be present so that the reading can take place. Additionally, for water utilities the annual reading is time-consuming, labor-intensive, and causes high expenses. In the 21st century, with everything going digital or even virtual - from planning and simulation to diagnostics, from offerings-as-a-service to digital twins, and from small IIoT components to AGVs, robotics, and e-mobility, the measurement of water is still largely done in an analogue manner. Why not use the benefits of digitalization to make readings easier, more comfortable, more reliable, and more efficient for all parties involved?

    How can we simplify water management?

    Colorless, odorless, indispensable for life. Arguably the most important, resource on the planet, water is under constant threat from climate change and leaky infrastructure. Ironically, while sea levels are rising on one hand, water shortages are becoming increasingly common on the other.
