Wastewater management is at the heart of environmental protection, because it seeks to avoid the pollution of our precious rivers, lakes and shores.
The sustainable protection of water bodies demands steadily increasing expenditures and efforts to reach legally required effluent quality.
In addition to the well-known classical treatment processes, changing requirements in water protection and increased public awareness generate the necessity to use innovative technologies.
It is of crucial importance to adequately take into account the economic impact as well as the ecological requirements in order to select the appropriate technology.
Pöyry provides comprehensive solutions for the most effective wastewater disposal and treatment operations that best meet the needs of our clients.
