Water and energy loss put pressure on the water industry

According to World Economic Forum 2017, a water crisis is evaluated as one of the highest risks to the world and with the largest impact.

As populations grow, pressures mount and finding a more sustainable relationship between water and energy supplies become critical in less than two decades.

Today, close to one third of the world’s population is estimated to live in water stressed and scarcity areas and by 2040, almost 20 % of all countries are anticipated to experience extremely high water stress.  

Yet, water and energy loss in the water sector are extremely high. In fact, the average amount of water wasted by waterworks is 40 % worldwide and 26 % in Europe – due to errors, leakages, and water pressure. 

At the same time, 4 % of global electricity is consumed by the water industry – a figure that is expected to double by 2040 – and water accounts for up to half of a municipality’s total energy bill.

Water industry challenges

Todays challenges - Danfoss

Today’s challenges Tomorrow’s achievements

The industry challenges reflect a growing need for efficient water supply and treatment.

The good news is that technologies to reduce energy consumption and leakages in all stages of the water cycle – from production and distribution to wastewater pumping and treatment – already exist.

Pressure management is key throughout the water cycle

Global Director at Danfoss Drives Segment, Mads Warming, explains why there is a need for more efficient water supply and treatment on a global scale.

Pressure control is key to reduce water and energy loss

Danfoss pressure sensors and variable speed drives are a key component for reducing water and energy loss throughout the whole water cycle.

Experiences from 112 systems in 10 different countries show that better pressure control reduces non-revenue water and unnecessary energy consumption significantly.

In average, improved pressure management leads to 38 % reduction in pressure and 53 % less new breaks. Among other benefits, the energy consumption is reduced by 20-40 % and the typical water leakage reduction is 38 %. Moreover, the improvements result in extended asset lifetime and fewer network related complaints.

Danish water utility sets new standards for sustainability

The Danish water utility, Aarhus Water, is running with only 6 % leakage and is fully CO2 neutral. Danfoss has contributed through the whole water cycle.

Bringing water and energy use into balance

The increasing global demand for water and energy has put immense pressure on both industries to find a path towards a more sustainable future. And pressure itself is the key to achieving this goal.

    It takes water to produce energy – as it takes energy to produce water. The mutual dependence of water and energy and the accelerating demand for both have a major global impact on economic growth and societies everywhere. To create a more sustainable future, we need to decouple the water industry from growing energy consumption.
