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.
The DST P140 pressure transmitter is designed to provide unrivalled reliability, durability, performance, and not least, digital possibilities in the water-pump market.

According to the UN, 1/3 of the world’s population will live in water stressed areas in 2025.
Non-revenue water levels differ around the world with 40 % as average and 26 % in Europe.
In less than two decades, demands will rise due to growing populations, urbanization, and a larger middle class.

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.
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.

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.
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.
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.
Danfoss KPI pressure switches are used for regulating, monitoring and alarm systems in industrial applications. The KP series are suitable for plant in connection with liquid and gaseous media.
Pressure transmitter, type MBS 1700 is designed to a variety of applications and easy installations within the distributor market. The transmitter offers highly reliable pressure measurement, ensuring that even the slightest change is detected immediately.
MBS 3000 is designed for use in almost all industrial applications, and offers a reliable pressure measurement, even under harsh environmental conditions.The flexible pressure transmitter programme covers all standard output signals.
For use in corrosive environments and with aggressive media, Danfoss offers the robust DST P40I pressure transmitter made of Titanium and with ceramic pressure sensing element. DST P40I is optimized for use in applications such as desalination systems, seawater cooling, and chemical processing.
The DST P140 pressure transmitter is dedicated for use in water pump and air compressor applications. It is designed to provide unrivaled reliability, durability, performance, and not least, digital possibilities.

The Marselisborg catchment area in Aarhus has achieved 100 % energy surplus production - by minimizing consumption throughout the whole water cycle and maximizing energy production from the wastewater facility.
POLAND: For more than a decade, Danfoss drives have halved the power consumption at Carlsberg’s Okocim Brewery. The brewery uses less water and has lowered its emissions too.
Over the past decade, the use of Sea Water Reverse Osmosis (SWRO) for desalination has taken off. With proven efficiency rates up to 92% and energy savings of up to 65% compared to traditional solutions, the opportunities of SWRO technologies deserve further exploration.
Non-revenue water has been a hot topic in the water industry for years. And for a good reason. In addition to the environmental consequences, non-revenue water has a major impact on the financial viability of water utilities due to water loss and unnecessarily high operating costs.
Throughout the entire water cycle, pressure plays a key role in ensuring an efficient, reliable, and sustainable water supply. And for decades, the water industry has struggled with numerous pressure-related challenges in the water system. By using intelligent pressure and flow management, a global study proves how water facilities can reduce unnecessary water and energy loss.
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.
Water puts pressure on people everywhere – whether they are struggling with too much, too little, or too dirty water. In fact, a water crisis is evaluated as one of the highest risks to the world and with the largest impact, according to the World Economic Forum. In this article, we outline the causes of this global water crisis – and offer a lifebuoy that can help us overcome it.
