Sweden’s 16 environmental objectivespoint the way to a sustainable society.
Here you will find best practice examples from the investment programmes within the water and sewage sector.
The Municipality of Söderhamn created a wetland alongside a sewage treatment plant. This resulted in a reduction in nitrogen emissions of 5.5 tonnes/year and in phosphorus emissions of 365 kg/year.
The Municipality of Strömstad has built a recycling plant on the Koster Islands that does not just treat the wastewater and reduce nutrient inputs to the Skagerak. It also deals with the residues from wet composting.
By conveying digested sludge from the sewage treatment plant to reed beds, the Municipality of Hässleholm has reduced its use of chemicals and nitrogen emissions. A cleaner sludge with a reduced content of organic environmental toxins has been obtained.
In the eco-district of Augustenborg, the City of Malmö has constructed an open stormwater system that collects and treats rainwater. The recurrent floods are now a thing of the past, and the load on the sewage treatment plant downstream has decreased.
Hammarby Sjöstadsverket in Stockholm, Sweden, was built as part of the Hammarby Sjöstad initiative, with the aim of halving environmental impact by demonstrating new technology and innovative solutions.
By running nutrient-rich wastewater from the Tönnersjö sewage treatment plant to the local plant nursery, the Municipality of Halmstad in Sweden has reduced nutrient emissions by around 20 kg phosphorus and 100 kg nitrogen annually.
