Water Treatment Companies in Germany

Water treatment companies in Germany have been able to adapt certain systems and processes to treat wastewater from a variety of sources and also to provide these services to consumers outside the country.

Germany has an available water supply of 188 billion m3. It is a country that is rich in water resources. In 2010, around 33.1 billion m3 of water was abstracted from groundwater and surface waters to supply both industries and private households. This is less than 20% of the available water supply, i.e. over 80% of the available water supply remains unused.

The mining sector and the manufacturing industry are the second biggest water users in the country, with the thermal power plants being the first. The agricultural sector uses the least amount of water in the country.

Over the past 20 years, water consumption reduced by at least 18% and this is due to the introduction of water treatment plants. In Germany, ensuring water supply is a mandatory duty of the state. A total of 10 billion m3 of wastewater was treated by water treatment companies in 2010, almost exclusively through biological wastewater treatment.

Water treatment is a paramount duty of the country as the major sectors that consume water also generate the highest volume of wastewater. This is where the need for water treatment companies come in. Rather than dispose of the wastewater from these sectors, the wastewater is treated and made available for reuse to these same sectors.

In all of Europe, Germany has the most efficient water management, as 96% of all its wastewater generated from industries and households is channelled to water treatment companies for purification.
