Global urbanization poses a number of water-related challenges – chief among them supplying clean drinking water and disposing of waste water.


Supplying millions of citizens every day with water is a task that requires much planning and the help of a large number of electrical and electronic water management systems and technologies. Millions of electric motors, pumps, valves, sensors and controls rely on IEC International Standards to work safely and efficiently in sometimes harsh environments. 

Fresh water
It starts at the water utility, where instrumentation keeps a close watch on water consumption and the data sent back from individual water meters. Water extraction pumps are used to pump water from wells or through pipelines to purification, filtration or desalination systems.
Building and industrial pumps ensure that water pressure remains constant even at the top floor of high-rises or during use in industrial processes.

A myriad of sensors control the start and stop of water flow for example at the individual faucet in your bathroom. They also help control timing and length of flush in toilets, avoid overflow in boilers and storage towers or sense soil water content or freezing temperatures in irrigation systems.

Waste water treatment
Centrally controlled, highly automated pumps, conveyor belts and sorting machines separate solids from other waste. Waste water is sent through settlement tanks where electrically driven scrapers push sludge to be pumped away. Rotating motors drive clarifiers and air pumps in aeration tanks to allow bacteria to break down the rests of sludge. Cleaned water flows back into rivers or is used for other purposes.
