Modernizing sewers and wastewater systems with new technologies: The Danish action plan for promotion of eco-efficient technologies - Danish lessons

Research output: Other contributionNet publication - Internet publicationResearch

Abstract

After continuous problems and challenges with dead fish and oxygen depletion in the waters, Denmark initiated an action plan for Danish waters to reduce pollution in the late 1980s. The action plan puts focus on stricter criteria for wastewater treatment plants. Over the years, the plan has been revised three times to ensure continuity in the work. As a result, Danish waters are significantly cleaner today. Since 1987 the pollution caused by wastewater has been reduced by 80 - 90 % - depending on the type of pollutant. Upgrading the wastewater treatment system with a number of new and innovative Danish technologies is one of the main contributions to this success. However, education of staff, improved legislation and good cooperation between several stakeholders played an important role as well.
