The challenge
Less than one percent of the water on our planet can be used by humans. This makes water the number one resource – far ahead of other raw materials. The demand for water has been rising continuously for years. Causes of this are globalization, climate change, population growth and an increasing trend towards urbanization, i.e. the spread of urban lifestyles. For many years, onoff GmbH has been supporting industrial and municipal companies in the water/wastewater sector that operate in areas ranging from water collection and processing to water treatment and purification. This customer has also been part of our customer base for seven years. With a capacity of over 1.3 million population equivalents, the sewage treatment plant is one of the largest and most modern in Europe.
