Electrical and electronic systems and equipment play an important role in the process of ensuring that clean water reaches everyone. They are an essential element in water extraction, transportation, purification and delivery to users.
Pumps are needed to extract water from rivers, lakes, oceans or from under ground and transport it to water works. Valves and sensors are needed to control water flow, pressure, temperature and liquid levels. They are indispensable in distributing water and in avoiding leakages.
Most water pumping stations are automated and many electronic devices are used for their control and supervision. Programmable logic controllers (PLCs) and remote terminal units (RTUs) are integrated in centralized control rooms with supervisory control and data acquisition (SCADA) systems.
The process for water purification and waste water treatment is a multiple-stage process that involves mechanical and chemical phases, all of which require electrical and electronic equipment in the form of pumps, chemical injectors and rotating arms driven by electric motors.
Billions of sensors regulate the flow of water in faucets and toilets in homes, offices, healthcare facilities or manufacturing plants.
