The global markets in clean drinking water production and transportation, as well as those of wastewater treatment are growing rapidly. Finnish companies have developed advanced mechanical, biological and chemical effluent treatment systems, sludge de-watering and internal process water treatment technologies, and process technologies in sludge treatment for municipal and industrial applications.

In recent years, especially technologies for removal of micro-pollutants from drinking water, utilization of treated wastewaters, recycling of industrial wastewaters, nutrient recovery and sludge treatment have been under development.

The leading Finnish environmental engineering companies are internationally renowned suppliers of water transmission and distribution systems, water treatment plants and municipal and industrial wastewater treatment plants. They have also developed solutions for monitoring the quality of drinking water and effluent, as well as surveying the pollution levels in natural waters.
