Drinking water

Drinking water treatment

The highest quality possible

We need clean water for drinking, personal hygiene, laundry and many other purposes. The average citizen in New South Wales consumes around 340 litres of water a day. In Dubai, average daily consumption is as high as 500 litres, while in Germany it’s just 130 litres. Regardless of local consumption habits, there's high demand for the security and quality of drinking water. We must manage water resources more sustainably and productively to provide a secure, reliable supply to our growing urban areas while allocating sustainable volumes of water for irrigation. Water treatment plants must be lean and efficient. Siemens can support you with regulatory requirements and help you fulfil quality standards. Our hardware, software and comprehensive services let you design, operate and maintain your plant – for efficient and sustainable drinking water treatment.


Clean water through high tech

In many parts of the world, demand for drinking water cannot be satisfied by groundwater alone. As a result, the treatment of surface water or even sewage is increasingly important, especially where water sources are scarce or polluted. Siemens’ intelligent automation systems, drive technology, industrial controls and power distribution ensure smooth operation of water treatment plants.

Energy efficiency

Drinking water is obtained primarily by purifying groundwater and surface water. The treatment depends on the quality of the raw water, determined by the substances it contains and what must be removed. Energy use is a big cost factor, however, up to 80% of electricity used in treatment plants is in the transport of raw and finished water.


Intelligent drive technology is decisive for pump and blower station availability and efficiency. It's also at the core of energy-efficiency initiatives in the water and wastewater sector. We help you achieve transparency in terms of energy demand in order to reduce costs significantly.

Asset life

Water treatment plants are often unmanned and are managed remotely from a central control room. Better network visibility is a chance to operate assets more efficiently. Many utilities are deferring capital expenditure through network optimisation and using real-time modelling to proactively address constraints.


Virtual control technology offers clear advantages: the entire control system server infrastructure is consolidated in a computer center. We facilitate your entry into future-oriented technologies with our lifecycle service that covers everything you need for a virtualization solution – all from a single source.

Planning and adaptability

For optimised operations, plants and infrastructure must be intelligently controlled and managed. Pumping stations are often far away and unmanned, so their components need to be rugged and reliable – but also interact perfectly in regard to process control technology, drive and automation engineering, process instrumentation, power supply and networking.
