New fact sheet describes effect of proposed UWWTD on nutrient inputs to the Baltic Sea
The requirements on wastewater treatment proposed in new EU Urban Wastewater Treatment Directive draft is unlikely to have a decisive effect on the nutrient inputs to the Baltic Sea. This is concluded in a new fact sheet, describing the requirements in the proposed directive in relation to the current situation regarding wastewater treatment in the Baltic Sea catchment.
Nutrient supply from the wastewater sector remains a large part of the anthropogenic inputs to the Baltic Sea. In October 2022, the European Commission proposed a recast of the directive regulating these emissions; the Urban Wastewater Treatment Directive (UWWTD).
A recently published fact sheet from Stockholm University Baltic Sea Centre describes how the total amount of wastewater is distributed between different fractions, and the current treatment efficiency of wastewater treatment plants.
